There are two types of PCBN sintered directly by CBN single-crystal sintering and PCBN sintered with a certain proportion of binder. According to the way of manufacturing composite: there are integrated PCBN sintered blocks and cemented carbide composite sintered PCBN composite pieces.PCBN composite tablets with the binder are widely used. The hardness of PCBN varies according to the proportion of binder added. The higher the binder content, the lower the hardness and the better the toughness. Different binder types, the use of PCBN is different. Grinding process of PCBN tool The produced blank body needs to be sharpened before it can be used for cutting. Generally divided into rough grinding, fine grinding, and grinding process. Rough grinding adopts no. 180 ~ 240 resin bond diamond grinding wheel, feeding volume is 0.01mm/double stroke. Wlo ~ W14 resin bond grinding wheel for fine grinding, feed 0.05mm/double stroke; Special attention should be paid to the effect of cutting edge dressing of diamond grinding wheel on cutting edge grinding. Although the cutting tool swings back and forth across the whole end face of the grinding wheel during the grinding process to make the surface of the grinding wheel consume uniformly. In fact, the surface of the grinding wheel is still prone to be uneven, which requires frequent dressing. Our company's tool grinding machine can grind PCD, PCBN and CVD insert. In addition, the PCBN tool can grind carbide and machine tool inserts, boring tools, HSS non-standard inserts, standard or non-standard welding lathe tools, grooving tools, and various other tools.

Carbide Insert Grinding Techniques For ManufacturesThe hard alloy blade has high hardness, great brittleness, poor thermal conductivity, and high thermal shrinkage. However, due to the high price of the diamond grinding wheel, it is difficult to repair after wear, so many factories still use the ordinary grinding wheels for cutting edge grinding. In the cutting edge grinding process, due to the high hardness of the hard alloy, the grinding grains of the ordinary grinding wheel is easy to be passivated. And the violent friction causes local high temperatures on the blade surface, forming the attached heating stress, easily causing thermal deformation and thermal crack, which directly affects the service life and processing quality of the tool. Therefore, necessary measures should be taken to prevent the emergence of blade grinding cracks. Through the processing practice, the following technological measures can be summarized to prevent or reduce the grinding crack effectively.Methods/stepsNegative edge sharpeningThe negative blade sharpening method is to grind a negative blade strip on the front or rear blade surface before sharpening the tool. Hard alloy is a hard and brittle material, and it is easy to vibrate and crack due to the vibration of the grinding wheel. At the same time, the thermal stress of the grinding zone may exceed the strength limit of the hard alloy and cause a thermal crack. The negative edge grinding method can improve the strength of the blade, enhance the vibration resistance of the blade, and the ability to bear impact load. And increase the heated area to prevent a large number of hot guide blades in grinding, so as to reduce or prevent cracks.Soak grinding wheel with molybdenum disulfideAt room temperature, powdered molybdenum disulfide and absolute ethanol can be made into a mixed solution. In order to prevent ethanol from volatilizing, a new ordinary grinding wheel is then immersed in the mixed solution in a sealed container. After 14 hours, the wheel was taken out and naturally dried for 18-20 hours, so that the grinding wheel was completely dried. The inner voids of the grinding wheel treated above are filled with molybdenum disulfide, which can lubricate the grinding grains and make the grinding wheel discharge chips well and not easy to be blocked. The test shows that when grinding hard alloy blade with molybdenum disulfide wetted grinding wheel, the grinding is sharp, the grinding grain is not easy to passivate, the workpiece deformation is small, chip discharge is smooth, the shape of the grinding chip is basically ribbon-like, which can take away most of the grinding heat, thus improving the grinding effect and increasing the yield of the blade.Reasonable selection of grinding dosageIf the friction force is too large in the grinding process, the grinding temperature will rise sharply and the blade will burst easily. Therefore, it is very important to select the proper grinding amount.Common reasonable grinding usage is: circumferential speed V =10 ~ 15m/min, feed f vertical =0.5 ~ 1.0m/min, f horizontal =0.01 ~ 0.02mm/ stroke.When hand grinding, longitudinal and transverse feed should not be too large.Other process measuresThe lack of rigidity of the tool pole, the instability of the tool clamping, and the runout of the machine tool spindle may cause the blade grinding crack. Therefore, the processing system composed of the machine tool, grinding wheel, fixture, and cutter should be rigid enough and the axial and radial runout of the grinding wheel should be controlled. There are many factors that cause a carbide tool to produce grinding crack. Only by selecting suitable grinding wheel and adopting reasonable grinding technology can crack generation be avoided effectively and the quality of grinding edge be improved.Demina tool grinding machine can grind carbide insert with high quality.

The user's scope of use is no longer restricted by the manufacturer. Grinding failure solution OF PP-50 universal tool grinder The role of the Universal tool grinder is mainly for the grinding of some metal tools such as turning tools, engraving knives, cutting plotters, etc. As a sophisticated instrument, the tool grinding machine rarely fails. But sometimes the PP-50 universal tool grinder is used. Plastic deformation, wear, fatigue and hot and cold fatigue, fracture and cracking, corrosion, etc. are encountered in the process, and these problems are mainly caused by the failure of tool grinding. In order to ensure the smooth production, the grinding of the universal tool grinding machine is in urgent need of a solution. Then Beijing Demina Precision Machinery co., ltd is a professional PP-50 universal tool grinder manufacturer. Next, we will teach you some universal tool for grinding machines. Let's learn about the countermeasures of cutting the failure! In response to the failure of the grinding of the universal tool grinding machine. The first is to rationally select the grinding amount and improve the speed of the workpiece and the universal tool grinding wheel, which can greatly reduce the occurrence of cutting heat. Secondly, it is reasonable to choose the model of the universal tool grinder and the dressing wheel. It is recommended to use the white corundum grinding wheel because it is hard and brittle and easy to produce new cutting edges. In addition, the hardness of the grinding wheel is medium soft and soft. That is, the grinding wheel with coarse grain size and low hardness. Because the self-excitation is good, the cutting head can greatly reduce. In addition, the quenching stress after heat treatment is reduced to a minimum. So that the grinding heat of the universal tool grinder is within the allowable range. Thus preventing the workpiece from being thermally deformed and avoiding the failure of the universal tool grinder grinding after prolonged use. In short, in the grinding operation of the tool resharpening machine. The grinding process should pay full attention to, and the operator should minimize the grinding microcracks and residual stresses. Only in this way can the service life of the grinding wheel greatly reduce, thus avoiding the root cause. The phenomenon of tool grinding failure. Grinding step of PP-50 universal tool grinder PP-50 universal tool grinder as a grinding machine, its most important function is grinding, and the main part of the tool grinding machine is the grinding wheel. The right grinding wheel can use to grind the sharp knife. Let's take a look at the steps of sharpening the turning of the tool grinder. The first step is the tool grinding machine. The first step is to grind the main flank and grind the main declination and the main relief. Then, the tool grinder is operated to grind the flank face, and the secondary declination and the sub-back angle are ground. Then grind the front, grind the front corner and grind the knives and tips. Secondly, the posture and method of the tool grinder sharpening knife generally require the operator to stand on the side of the grinder to prevent the debris from flying out and hurting when the grinding wheel breaks. In addition, the distance between the operator holding the knife should release, and the elbows are clamped to the waist to reduce the jitter during sharpening.

The motorized spindle is the last ten years in the field of CNC machine tools will machine tool spindle and spindle motor integration of new technology. It is the “core” components of high-speed CNC machine tools, its performance directly determines the high-speed machining performance of machine tools.As motorized spindles are high-speed precision components regular maintenance is very necessary. The motorized spindle is maintained as follows:1. The radial runout of the inner cone hole of the motorized spindle is generally required to be 0.002mm(2 m) and detected twice a year.2. The radial runout of the far end of the spindle (250mm) is generally required to be 0.012mm(12 m) and tested twice a year.3. The extended distance of broach is 10.5±0.1mm when the broach is released (take HSK63 as an example) for 4 times a year.Analysis and treatment of severe heating during high-speed rotation of spindle:Heat and temperature rise in spindle operation is always the focus of research. There are two main heat sources inside the spindle unit: one is the spindle bearing, the other is the main motor.The most prominent problem of the spindle unit is the heating of the main motor. As the main motor is next to the spindle bearing, if the heat dissipation of the main motor is not solved well, it will also affect the reliability of the machine. The main solution is to adopt the cycle cooling structure, including the external cycle and the internal cycle. The cooling medium can be water or oil so that the motor and the front and rear bearings can be fully cooled.Spindle bearing is the core 2113 core support of motorized spindle and also one of the main heat sources of the motorized spindle. At present, high-speed motorized spindles are mostly made of angular contact ceramic ball bearings. Because ceramic ball bearings have the following characteristics:1. Because of the lightweight of the ball, the centrifugal force is a small, a small moment of dynamic friction.2. Small thermal expansion caused by temperature rise, so that the bearing pre-tightening force stability.Small elastic deformation, high stiffness, long life. Due to the high running speed of the motorized spindle, there are strict requirements for the dynamic and thermal performance of spindle bearing. Reasonable preload, good and sufficient lubrication is necessary to ensure the normal operation of the spindle.Oil mist lubrication is adopted. The air pressure of the atomizing generator is 0.25~ 0.3mpa. 20# turbine oil is selected. The lube mist, while fully lubricating the bearings, also carries away a lot of heat. The distribution of lubricating oil in the front and rear bearings is a very important issue and must be strictly controlled. The inlet section is larger than the sum of the sections of the front and rear injection orifices, and the exhaust shall be smooth. The injection Angle of each injection hole is 15O with the axis so that the oil mist is directly sprayed into the bearing working area.Key Points Of The Motorized Spindle Maintenance Process1. According to the damage of the motorized spindle, measurement of static, dynamic radial runout and lift clearance, and axial movement momentum.2. Remove the motorized spindle with a special tool made of 5261. Clean and measure rotor pendulum and wear.3. Optional bearing. The consistency error of the inner hole and outer diameter of each group of bearings shall be ≤0.002~0.003mm. Keep a clearance of 0.0025~0.005mm from the main shaft. In practice, it is best to use both thumbs to push the bearing into the sleeve. Too tight will cause bearing outer ring deformation, bearing temperature rise is too high, too loose will reduce the stiffness of the grinding head.4. Bearing cleaning is to ensure the normal work and service life of the important link, do not use compressed air to blow the bearing, because the compressed air in the hard particles will make the racetrack hair.5. Tapered bearings or angular contact ball bearings must pay attention to the direction of bearing installation, otherwise, they can not reach the rotary precision requirements. The whole assembly process adopts special tools to eliminate assembly errors and ensure assembly quality.6. When the inner hole of the sleeve is deformed, the roundness is out of tolerance, or it is too loose with the bearing. The local electroplating method can be used to compensate and regrind to the requirement, and this method can also be used at the shaft neck.7. The end face of the round nut and oil seal cover on the motorized spindle is in close contact with the end face of the inner and outer rings of the bearing respectively. Therefore, the perpendicularity of the threaded part and the end face is very high. If the contact rate & LT;80%, can grind the end face, make it reach perpendicularity requirement.4102 this work is very important. Its accuracy will affect the radial runout of the grinding spindle extension rod, thus affecting the surface roughness of the grinding workpiece.8. The spindle shall be adjusted in axial direction after assembly (measured by tension spring balance during adjustment). At the same time, static and dynamic radial run-out and lifting clearance shall be measured until the assembly process requirements are met.9. Under the actual running conditions of the machine, excluding the influence of assembly. Thermal deformation, and other factors during the operation of the machine, under a certain rotating speed, a dynamic balancing instrument is used to balance the rotor in motion.Maintenance Analysis And Elimination Method Of Common Faults Of Motorized Spindle1. Spindle heating(1) The spindle bearing preload is too large, causing the spindle rotation friction too large, causing the spindle temperature sharply increased.Troubleshooting: It can be eliminated by readjusting the preload of the spindle bearing.(2) Spindle bearing grinding or damage will also cause spindle rotary friction too large, resulting in a sharp rise in spindle temperature.Troubleshooting: It can be eliminated by replacing new bearings.(3) Spindle oil dirty or impurities will also cause spindle rotation resistance is too large, causing spindle temperature rise.Troubleshooting: remove the problem by cleaning the headstock and changing the oil.(4) When the lubricating grease of spindle bearing is exhausted or too much lubricating grease, it will also cause the resistance and friction of spindle turning to be too large, which will cause the temperature of the spindle to rise.Troubleshooting: Remove by reapplying grease.2. Spindle when the strong cutting stop(1) The transmission belt connecting the spindle motor and the spindle is too loose, resulting in too small spindle drive torque, insufficient spindle torque during strong cutting, the alarm will be generated, and the CNC machine will stop automatically.Troubleshooting methods: By adjusting the tension of the main shaft belt, to eliminate.(2) There is oil on the surface of the transmission belt between the spindle motor and the spindle, which causes the transmission belt to slip when the spindle is driving. In the case of strong cutting, the spindle torque is insufficient, giving an alarm and the CNC machine stops automatically.Troubleshooting: Remove by scrubbing after cleaning with gasoline or alcohol.(3) The driving belt connecting the spindle motor and the spindle becomes invalid after being used for too long, which causes the spindle motor’s torque to be unable to drive. When the spindle torque is insufficient during strong cutting, an alarm will be generated and the CNC machine will stop automatically.Troubleshooting: remove the fault by replacing a new spindle drive belt.(4) In the spindle driving mechanism, the clutch, coupling connection, adjust too loose or wear, resulting in the spindle motor torque transmission error is too large, strong vibration spindle cutting. Generate alarm, NC machine automatically stops.Troubleshooting: remove by adjusting or replacing the clutch or coupling.3. Too much noise when the spindle works(1) Poor dynamic balance of spindle components, so that the spindle rotation vibration is too large, causing working noise.Troubleshooting methods: All spindle components should be checked and adjusted by professionals from the machine tool manufacturer.(2) Spindle transmission gear wear, so that the gear meshing clearance is too large, spindle rotation impact vibration is too large, causing work noise.Troubleshooting: it is necessary to have the spindle drive gear inspected, repaired, or replaced by a professional from the machine tool manufacturer.(3) Spindle bearing drawing or damage, so that the spindle rotary clearance is too large, rotary impact, vibration is too large, causing work noise.Troubleshooting: Professional personnel from the machine tool manufacturer are required to inspect, repair, or replace the bearings.(4) The spindle belt slack or wear, so that the spindle rotary friction too large, causing work noise.Troubleshooting: remove by adjusting or replacing the belt.4. The tool cannot be clamped(1) The displacement of the dish spring is too small so that the spindle grasping knife, clamping device cannot reach the correct position, the tool cannot be clamped.Troubleshooting: by adjusting the stroke length of the spring dish to eliminate.(2) The spring chuck is damaged, making the spindle clamping device unable to clamp the cutter.Troubleshooting: remove the problem by replacing the spring chuck.(3) Disc spring failure, so that the spindle grasp knife, clamping device can not reach the correct position, the tool can not be clamped.Troubleshooting: remove the problem by replacing a new dish spring.(4) The pull nail on the handle is too long and hits the grasping knife and clamping device of the spindle, making it unable to move to the correct position and the tool cannot be clamped.Troubleshooting methods: By adjusting or replacing the pull nails, and correct installation to remove.5. Do not loosen the tool after it is clamped(1) Release hydraulic cylinder pressure and stroke is not enough.Troubleshooting methods: By adjusting the hydraulic pressure and stroke switch position to eliminate.(2) Saucer spring pressing is too tight so that the spindle clamping device cannot fully move to the correct position, and the tool cannot be released.Troubleshooting: by adjusting the nut on the dish spring, reduce the spring pressure to eliminate.1653 electric spindle for a high-speed CNC machine tool is the most key component, its performance depends to a large extent determines the processing accuracy and production efficiency of the high-speed machine tools, electric spindle as the core component of the machining center. It will close 2 for one, machine tool spindle and ac servo motor shaft of the spindle motor stator and rotor directly into the interior of the spindle component, and through the accurate dynamic balancing correction, have good rotation accuracy and stability, forming a perfect high-speed spindle unit, also known as the built-in motorized spindle, it no longer USES the belt gear transmission, so as to realize the “zero transmission” of machine tool spindle system. After energizing, the rotor drives the spindle directly.

Grinding wheel in the mechanical industry and grinding work. More and more widely used, so that much professional academic staff. Continue to innovate and research and study for the identification and installation of the grinding wheel. Below, we give you some advice, in the identification and installation of grinding wheel Avoid unnecessary problems The selection of the grinding wheel is mainly determined according to the conditions of the grinding machine. The shapes of the workpiece, material properties, and other factors. Generally, the appearance and cracks of the grinding wheel need to be carried out after the grinding wheel is selected identification. But sometimes the cracks in the grinding wheel is not easy to observe, should use the sound test method. Such as the mallet tap to listen to the sound, the sound of salt is no crack a good grinding wheel. As for the selection of grinding wheel should consider comprehensively. In consideration of size, generally should as large as possible to choose the outer diameter. Vertical grinding should select a wide grinding wheel. When grinding the inner circle, the outer diameter of the grinding wheel should about 2/3 of the diameter of the workpiece. Special attention should pay to the fact that the linear speed of the grinding wheel is not allowed to exceed the market value. Balance and installation of grinding wheel Sometimes, during the installation of the grinding wheel, the unbalanced grinding wheel will vibrate when rotating at a high speed. This will affect the machining quality measuring and machine tool accuracy. Serious inches will also cause grinding wheel rupture, endangering the safety of people and equipment. The main reason for unbalance is that the density of each part of the grinding wheel is not uniform, geometric asymmetry and installation eccentricity. Therefore, we must balanced the grinding wheel before installation. The balance of grinding wheel includes static balance and dynamic balance two kinds: - under normal circumstances, only do static equilibrium. And in high-speed grinding and high precision grinding, must enter the action balance. For large diameter grinding wheel, in use - section after the time, due to the grinding wheel wear, there may be an imbalance, need to balance again. Through the above analysis, I believe that everyone will have a certain understanding of grinding wheel identification and installation. So as to avoid various problems in the installation of the grinding wheel, causing damage to the workpiece, etc.  

Structure Of Cylindrical Turning Tool1. The front.The surface on which the cuttings flow. It can be a plane or a surface to make the chip flow out smoothly.2.The back. The surface opposite to the transition surface on the workpiece, also known as the back knife surface, is tilted at an Angle to reduce friction with the workpiece.3.Vice rear. The surface on a tool opposite to the machined surface at an Angle to avoid scratching the machined surface.4. Main cutting edge. The intersection line between the front and back of the tool is responsible for the main cutting task.5. Auxiliary cutting edge. The intersection line between the front and rear of the tool is only responsible for a small amount of cutting tasks.6.Point.The intersection point of the main cutting edge and the auxiliary cutting edge, which is not absolutely sharp, is generally in the shape of an arc to ensure that the tip has enough strength and wear resistance.(1) Make the knife body turn to the left according to the main Angle, and make the head turn up according to the size of the main back Angle.(2) Then make the knife body to the right according to the size of the side Angle, and make the knife head upward according to the size of the side back Angle, and grind the side back seedling to produce the side Angle and side back Angle.(3) Make the front knife face tilt according to the size of the front Angle, make the head tilt up or down according to the size of the blade inclination, and grind the front knife face.(4) Then grooving can be done by the edge of the grinding wheel.(5) Finally, chamfer and finish.Demina tool grinding machine can grind the cylindrical turning tool with high efficiency. Welcome to our customers to visit us.

The negative chamfering refers to the sharpening of a specified angle and the width of the chamfering edge on the insert. The negative chamfering increases the wedge angle of the cutter enlarges the heat dissipation area and increases the deformation of cutting chip. Which is of great significance for improving the tool life and the rolling of chips. Therefore, it is very important for grinding the right negative chamfer. It is special equipment for the negative edge of the insert. The chamfering can carry out according to different angles of the insert. And the grinding wheel can carry out according to different angles of the insert. And the grinding wheel can dress at any time, so as to ensure that the high quality negative chamfer with different requirements. The adjustment of the negative chamfering angle The model BT-300 machine is using the adjustment iron plate for negative chamfer angle according to the need for specialized angle adjustment. With four angle adjustment plates, 10 degrees, 20 degrees, 25 degrees, 30 degrees. Changing the angle adjusting plates on the fixing plate. It can grind different negative chamfer, to meet the requirements for chamfering insert angle. It is easy to operate and replace, just screw down the screw. Dressing of the grinding wheel In the chamfering process, the grinding wheel will wear with grinding. Resulting in the phenomenon of the uneven surface of the grinding wheel. Therefore, it can timely dress the grinding wheel flat, and it is also important for grinding high quality insert chamfering. BT-300 uses the dressing mechanism of swing arm type. The oil stone installed on the swingarm at the same time. To ensure the contact surface of the grinding wheel and the grinding stone is completely the same. Eliminates grinding uneven, ensure the smooth surface after grinding wheel dressing. In the process of dressing the grinding wheel, the rotary arm hand wheel is used to feed the oil stone to keep the oil stone and the grinding wheel in a dressing state.

Cemented carbide is an alloy material made of a hard compound of refractory metal and binding metal by the powder metallurgy process.The hard alloy has high hardness, good wear resistance, strength and toughness, heat resistance, corrosion resistance, and a series of excellent properties, especially its high hardness and wear resistance, even it is basically unchanged even at very high temperatures.Hard alloy is widely used as cutting tool material, such as turning tool, milling tool, planer tool, drill bit, boring tool, etc., used for cutting cast iron, non-ferrous metal, plastic, chemical fiber, graphite, glass, stone, and ordinary steel, but also can be used for cutting heat resistant steel, stainless steel, high manganese steel, tool steel and other difficult to process materials.High hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC).Good heat and hardness (up to 900 ~ 1000℃, maintain 60HRC).Good wear resistance.Carbide cutting tools have 4 ~ 7 times higher cutting speed and 5 ~ 80 times longer tool life than HSS. Manufacture die, measuring tool, life is 20 ~ 150 times longer than alloy tool steel. It can cut about 50HRC hard material.But the hard alloy is too brittle to be machined, so it is difficult to make the complex shape of the whole tool, so it is often made into different shapes of the blade, using welding, bonding, mechanical clamping and other methods installed in the tool body or die specific use.
