  • Features And Uses Of PCD&PCBN Tool Grinding Machine

    Most designs of the 2-axis PCD&PCBN tool grinding machine have the following two characteristics: First, while sharpening the PCBN and PCD tools, taking into account the natural diamond tools; Second, sharpening and welding super-hard turning tools and boring tools, but also taking into account the disc and shaft tools. Features of PCD&PCBN tool grinding machine At present, with the rapid development of the market and technology, PCD & PCBN tool grinding machine has been widely used, so the market for PCD & PCBN tool grinding machine. Grinding equipment places high demands on grinding efficiency, mainly as follows. 1. The main part of the auxiliary time requires a significant reduction in the working time of the knife. The rotation of the table to form the arc of the blade, the adjustment of the center of the tool arc to coincide with the rotation axis of the table is a prerequisite for grinding. And the "tool setting action" runs through the entire process of tool grinding and is repeated continuously. This is the fundamental reason why traditional machine tools can't get rid of manual operations. 2. The operation is convenient and reliable, try not to rely on the manual skills of the operator. In order to grind natural diamond tools, conventional machine tools introduce the processes of "flexible feed" and "constant pressure grinding". These two processes have a "knife" protection effect on a very brittle natural diamond knife. Conventional equipment uses a cylinder feed to achieve this effect, which greatly sacrifices the grinding efficiency of the PCD & PCBN tool grinding machine. 3. Increase the specific gravity of the indexable insert grinding, which requires the equipment to have a strong specialty, simple and rigid structure. With the deepening of the division of labor, more than 80% of customers use the same equipment for the same type of tool, namely PCNB, PCD or alloy indexable inserts and welding tools. However, for a single requirement, the machine structure can be simplified and the rigidity of the device can be greatly enhanced. This not only reduces equipment costs but also lays the foundation for solid and efficient production. Uses of PCD&PCBN tool grinding machine 1. Can achieve large margin rough processing The integral can realize large-volume roughing. At present, the integral CBN tool can reach a depth of 8mm, can eat the entire blade, and the production efficiency is doubled. 2. High-speed cutting Thanks to the good performance of the PCBN tool itself, high-speed cutting can be achieved completely. And it can perfectly combine with CNC machine tools, which makes high-efficiency cutting of workpieces greatly improve production efficiency. 3. Dry processing Due to the high thermal redness of the PCBN tool, if the coolant is added, the blade will crack due to the sudden drop in temperature. Therefore, the CBN tool generally uses dry cutting when machining the workpiece, especially in the case of intermittent cutting. Turning is not only environmentally friendly but also saves a certain cost. 4. Suitable for processing high hardness materials The hardness of the CBN material is after the diamond and the PCBN is a very hard tool material that is second only to diamond. Therefore, the diamond tool is collectively referred to as a superhard tool. Normally, the PCBN hardness is better than 48HRC (the CBN wears very quickly when processing soft materials). The temperature is as high as 2000 ° C and there is excellent red hardness. Proper custom PCBN tools can withstand the high heat roughing of the cutting load, the interrupted cutting, and the heat and wear required for fine machining. In general, the 2-axis PCD&PCBN tool grinding machine is currently the most ideal tool material for processing ferrous metals. In the future, with the application of high-hardness and difficult-to-machine materials, the market share of PCBN tools will gradually increase. Will become the mainstay of the hard materials processing industry.  
  • The General Steps Of Cutting Fluid Selection

    The choice of cutting fluid must consider the machine tool, cutting tool, processing technology, and other comprehensive factors to determine, as shown in the figure to choose the steps of cutting fluid. Before the cutting fluid is selected according to the machining method and required accuracy, limited items such as safety and waste liquid treatment are set.Where fire and safety are emphasized, consideration should be given to choosing a water-based cutting fluid. When selecting a water-based cutting solution, the problem of waste solution discharge should be considered and the enterprise should have facilities for waste solution treatment. Some procedures, such as grinding, generally can only choose water-based cutting fluid. For the use of carbide tool cutting, generally consider the choice of oil-based cutting fluid.Some machine tools use oil-based cutting fluid in the high-efficiency regulations. Do not use water-based cutting fluid lightly, so as not to affect the performance of the machine tool. By weighing these conditions, you can decide to choose oil-based or water-based cutting fluid. After determining the main items of the cutting fluid. The second step can be selected according to the machining method, required machining accuracy, surface roughness, and other items as well as the characteristics of the cutting fluid, so as to meet the requirements of the selected cutting fluid. Expected identification requirements. Determine whether there is a problem, solve it again, determine the cause of the problem, improve it, and finally make a clear choice.Demina tool grinders use water-based cutting fluid. It’s very environmental protection. Welcome the customers to go to our factory for tool grinding.
  • Demina Successfully Developed The BT-150HG PCD Tool Grinder

    Grinding as a final finishing process, a large part depends on the experience and skills of skilled workers. But with the retirement of the technical workers of Japan’s “general generation”, Skilled workers are steadily declining. So the need for high-level processing equipment that does not rely on operating technology is increasing. Production of BT-150HG PCD tool grinder With the increasing demand in the market, Demina has developed the BT-150HG PCD tool grinder with stable machining accuracy regardless of who can operate the machine with high-level machining. As a leading manufacturer in the field of grinding machines, with years of accumulated thermal displacement correction technology and control technology. Even highly qualified workers can achieve high-precision machining operations comparable to skilled workers. In addition, in order to respond to the needs of a wider range of users, Demina has expanded the following three models in the product line. 1.PCD universal edge grinder: stable grinding accuracy; 2.: play the professional specifications of artisan technology; 3.PCD tool analyzer: A high power specification that enables high efficiency grinding. As a leading manufacturer of grinding machines, we will continue to use high-value-added technological innovations such as “high precision”, “high productivity”, “high reliability” and “usability” in developing countries using advanced Japanese manufacturing technology. Features of BT-150HG PCD tool grinder 1. Stable grinding accuracy Precision BT-150HG PCD tool grinder reduces the influence of heat on the machine bed and reduces thermal displacement due to room temperature changes. Machining heat, and mechanical heating of the motor and pump. The shape of the bed and the distribution of the ribs have been improved, and the heat generation of the machine body is suppressed by blocking heat transfer inside the machine tool, suppressing thermal expansion, and balancing heat capacity. An insulating cover is used on the path of the cutting fluid to form an air layer with the bed, which reduces the thermal influence of the cutting fluid on the bed. Equipped with an air-cooled grinding wheel bearing oil fan to reduce the rise in bearing oil temperature. On the grinding wheel table and the work table, a floating plate that absorbs the vibration of the ball screw is assembled. And the vibration of the lead screw is absorbed without increasing the rigidity in the feeding direction to improve the straightness and the processing surface characteristics. Moreover, in order to allow the customer to use it for a long time, the "scraping" process is performed by the skilled technician on the grinding wheel table and the table guide surface, so that the wear of the sliding surface by the feed friction can suppress. 2. Easier operation - improved PCD performance It is equipped with the latest PCD device independently developed by Demina. Compared with the previous models, the calculation speed is increased 5 times, the communication speed is increased 10 times, and the non-machining time is shortened. By digitizing the grinding conditions that were previously set by the skilled technician's feelings and experience, the rigidity of the workpiece can automatically be determined by simply inputting the length and diameter of the workpiece. And the most suitable grinding conditions are automatically determined. The iconic representation of the operation buttons is convenient for use by users around the world. 3. Safe, assured, convenient operation The use of a closed protective cover not only improves safety but also prevents the environmental impact of grinding dust and dust dispersion. Taking into account the proximity to the workpiece, by expanding the opening of the front door of the machine, the operator can work in a more relaxed position. It is equipped with the function of removing the grinding wheel from the workpiece when the power failure is detected. Preventing the grinding wheel and the workpiece from being damaged. 4. PCD tool analyzer: play professional specifications of artisan technology In order to satisfy the desire of skilled workers to perform the same handwheel operation as a hydraulic machine on a PCD machine. A "professional handwheel" that reproduces the feel of a hydraulic machine is standard. The configuration of the operation buttons and the weight of the handwheel can customize according to the requirements of the customer. There is enough space between the handwheel that operates the X-axis and the handwheel that operates the Z-axis to allow the worker's foot to step in and improve the accessibility to the workpiece. When operating manually, there is a PCD display screen that is unique to manual operation. 5. PCD universal edge grinder: high power specifications for high-efficiency grinding In order to meet the customer's expectation that high-load grinding such as super-hard material roughing can also carry out on compact equipment. We have high-power grinding wheel shaft +5.5kw small high-performance on . Rate motor. The grinding wheel shaft is 1.7 times more rigid than tool analyzer and the motor's power is increased by 1.5 times.

  • Common Problems And Repair Methods Of CBN Tool Sharpening Machine

    Maintenance adjustment of CBN tool sharpening machine During the operation of the CBN tool sharpening machine, some problems will inevitably occur. What should I do? In fact, we must pay attention to the regular maintenance and adjustment of it. It can measure with the feeler gauge on the full length of the 5-axis CBN tool grinding. At this time, the vibrating flywheel moves the upper tool holder up and down several times, and gradually tightens the bolts, nuts, and adjustment edge gap values ​​to meet the requirements. Then re-adjust the other one without adjustment, initially adjusting the knife-edge of the automatic sharpener to zero. CBN tool grinding machine tool generally consists of an organic body, task table, electromagnetic table, grinding head, and electric appliance. The structure between the components is compact, the external configuration is reasonable, the grinding head is even. The configuration is accurate and the task obeys. High, long life and other characteristics, it is used in the processing of all kinds of straight edge tools. Moreover, when adjusting the sharpening machine, restart the distance and adjust it with a feeler gauge. For various thicknesses of the sheet material, the cutting edge gap is different. Common problems and repair methods of CBN tool sharpening machine Any machine has a lifespan. After the expiration of the use period, there will always be some faults. The 5-axis CBN tool grinding machine will also have such problems. For these small problems, once you find the cause of the malfunction, you can solve it yourself. 1. The sound is loud when the spindle rotates. The spindle sound is very loud, mostly due to the difference in the bearing position, or the screw that is holding the spindle is loose. When this problem is encountered, we should even replace the sharpener spindle or tighten the screws. 2. When the switch is turned on, the motor does not turn. When we encounter this problem, we must first check the circuit. If the switch is broken, we should replace the switch. If it is a line problem, we will repair the line. 3. After the boot, the belt will automatically slide down. The belt slips due to the loose belt. The distance between the two pulleys should adjust to tighten the belt. 4.CBN tool grinding machine the sharpened knife has a taper. When this problem occurs, we should adjust the scale on the cutter head so that the cutter head is perpendicular to the spindle. CBN tool grinder determines the quality of the product determines the quality, efficiency and development ability of the product to a large extent. With the miniaturization of parts and the improvement of precision requirements, the machining precision tolerance of some tool grinding machines is required. And the development of tool grinding machine industry is facing development.

  • Principle Of Diamond Grinding Wheel Dresser

    Everyone who produces diamond grinding wheels knows that the important factor that affects the grinding performance of a grinding wheel is dressing, and reasonable dressing will affect the quality and grinding accuracy of the workpiece. So what is the soft elastic dressing method of the diamond grinding wheel?The principle of the soft elastic dressing method of the diamond grinding wheel is that when dressing, the belt is put on the belt wheel. Due to the high-speed operation of the diamond grinding wheel, the winding theory will gradually roll, so that the belt will be driven. The touch force of the grinding wheel removes the bond between the abrasive grains on the surface of the diamond grinding wheel to achieve the purpose of dressing.The dressing tool of the soft elastic dressing method, the abrasive belt is always touched by the dressing wheel with new sharp abrasive grains, which can form an outstanding dressing environment, remove the bond between the abrasive grains on the surface of the diamond grinding wheel, and the grinding force is small during dressing, the surface quality of grinding is high.The dressing of the superhard abrasive wheel of the diamond grinding wheel is usually divided into two stages: shaping and sharpening. The purpose of shaping is to remove the shape error and surface defect of the grinding wheel after initial installation and to ensure the geometric shape precision of the grinding wheel. Sharpening is due to the passivation of the grinding wheel after working for a period of time. In order to make the cutting edge protruding the binder and having an appropriate height, sufficient chip tolerance space should be formed between the grinding grains, and the effective number of grinding grains per unit area should be as large as possible.
  • Cubic Boron Carbide Cutting Tool

    Cubic boron carbide cutting tool When cutting materials with HRC55 ~ 65 hardness, the cutting speed of the cubic boron nitride tool should be 50 ~ 120m/min.During milling, Vc=100 ~ 160m/min, feed per minute Vf=70 ~ 160mm/min.Vc= 60 ~ 130m/min, ap=0.1 ~ 0.2mm, f=0.07 ~ 0.2mm/r. The hardness of the workpiece is higher than 45HRC, and the effect is the best. The higher the hardness of the workpiece is, the cutting line speed should the lower. For example, if the hardness of the workpiece to be ground is 70HRC, the cutting speed should be 60-80m / min. When the cutting depth of the fine turning is 0.1 ~ 0.3mm, the feed amount is 0.05 ~ 0.025mm / r, the surface roughness of the workpiece after finishing turning is Ra0.3 ~ 0.6m, and the dimensional accuracy can reach 0.013mm. Therefore, the user must choose according to the actual situation when carrying out the grinding work, so as to achieve a better grinding effect. If a standard CNC lathe with good rigidity process the machine, good rigidity of the cutting tool and sharp edge, the surface roughness of the workpiece after finishing can reach ra0.3m, the dimensional accuracy can reach 0.01mm, which can reach the level of machining with CNC grinder. Secondary deflection Angle: according to the choice of surface finish, the deflection Angle is smaller when high. The radius of the tooltip: general carbide turning tool r=0.5-2mm, a small value for rough turning.
