  • PCD Forming Tool Processing

    The improvement of tool performance is closely related to the progress of tool manufacturing technology. As advanced tool materials such as PCD become more popular in the marketplace, toolmakers will find faster, higher quality, and more cost-effective ways to manufacture these tools. The integration of other processes (such as EDM) with traditional grinding technology is a good example of how advanced technology can be used to meet the challenge of manufacturing super-hard tools.Processing Of PCD Forming ToolCutting tooltip shapes from PCD and CBN composite chips is a time-consuming task, and automated processing minimizes the labor costs of the process. The shape of the cutting edge with PCD tip was customized by EDM and wire-cutting technology. The machine tool control system can program the size and shape of the tool by inputting the size value of the tooltip on the two-dimensional drawing. For specific machining tasks, whether the EDM can meet the tool surface finish requirements depends on the EDM generator parameter settings. Different parameters can correspond to different machine tools and operators.Wire-cutting has an advantage over machining with a rotating electrode: it can produce tiny inner arc radii and other complex tool characteristics that EDG cannot process with a rotating electrode. However, on the other hand, EDG is different from other electrode wires. The rotating electrode made of the entire tungsten copper material is very hard and will not deform. This ensures a certain degree of processing consistency and a higher material removal rate. However, when the removal amount of the PCD blank is more than 0.3-0.4mm, the performance advantage of the rotating electrode will be reduced, and linear cutting becomes easy. 
  • Self-sharpening Of The Grinding Wheel

    The grinding wheel has the function of self-sharpening The tool used in the grinding process is the grinding wheel, which is a multi-blade tool bonded by grinding particles and binders. The abrasive particles are of different shapes and are irregularly distributed. Each abrasive particle is equivalent to a knife tooth. During grinding, the grinding wheel has a high circumferential speed, generally about 35M/S. In addition to cutting the workpiece surface, the grinding wheel also has a strong role in extrusion and friction polishing. And the instantaneous temperature in the grinding area is up to about 1000℃. Abrasive is a kind of high hardness non-metallic crystal. It can not only grind copper, aluminum, cast iron, and other soft materials but also can grind a variety of hardened hard steel, high-speed steel, and hard alloy and other hard materials. After dressing the working face of the grinding wheel, can form a very fine cutting edge to cut off the extremely thin metal layer on the surface of the workpiece. And grinding also has a very high metal removal rate, such as through strong grinding, a cut of 2~20mm metal. Grinding can obtain extremely high machining accuracy and extremely low surface roughness. With mirror grinding, the surface roughness of the workpiece can be up to ra0.01um, the surface of the workpiece is as smooth as a mirror, the size accuracy and shape accuracy can up to 1um, and the error is equivalent to 1/70 or less of the thickness of a person's hair. When grinding the grinding wheel, some blunt grinding grains can automatically fall off or break under certain conditions, exposing new sharp grains to participate in the grinding process. This feature is called the "self-sharpening" of the grinding wheel, which can keep the grinding performance of the grinding wheel good.
  • Operation Scheme Of BT-150D CNC Tool Grinder

    BT-150D CNC tool grinder is a precision grinding equipment. In industrial production, it is commonly used to grind PCD tools, CBN tools, and carbide tools. However, during the grinding process, in order to ensure the safety of the operator, according to the working nature and machining accuracy requirements of the CNC tool grinder, the following points are proposed for the operation of the equipment.Operation Scheme Of BT-150D CNC Tool Grinder1. CNC tool grinder is a kind of fine processing machine tool. In order to ensure the processing accuracy requirements of the equipment, the grinding machine needs to be stable during operation. The reciprocating motion of the worktable requires small inertia and no impact force when changing directions. Therefore, the hydraulic reciprocating motion of the worktable uses hydraulic transmission for the work process.2. In order to simplify the mechanical transmission organization of the grinder, multiple motors are selected for dragging alone. The CNC tool grinding machine uses three motors for dragging, and the rotary motion of the grinding wheel is dragged directly by the mounted motor.3. In order to improve the grinding quality and efficiency, a higher speed of the grinding wheel is required. Generally, the north-south and north-south cage asynchronous motors are used for dragging. In order to improve and adjust the style of the grinding wheel spindle, we can use a built-in motor to adjust the grinding wheel spindle.4. BT-150D CNC tool grinder the reciprocating pendulum mechanism of the grinding head. The grinding wheel consumes evenly and grinds in time to ensure grinding accuracy and roughness. The CNC program-controlled grinding wheel swing and moves very smoothly through speed optimization. You can set the oscillation length, position, and frequency in the program.The above are some operation plans about the BT-150D CNC tool grinder. I hope to help everyone use the equipment better.

  • Mechanical Structure

    Various types of machine tools, manufacturing technology is also a variety of, here the main problem is the stability of the bed, technology, and cost. The base of BT-150D 4-Axis CNC PCD Tool Grinder is made of solid casting with high quality. It can meet the grinding requirements of any hard material. Characteristics of cast iron bed adopted The cast iron bed adopted by this machine has the following characteristics: 1. The casting bed is made of gray cast iron, which has high carbon content and is not easy to be deformed by heat. 2. Casting the bed, one body, after aging treatment, its internal stress can almost be ignored, thus high stability can make the accuracy of the machine tool for a long time to maintain. 3. Compared with the ordinary welding bed, the casting bed is much heavier. In theory, the heavier the bed is, the smaller the machine vibration is, and the less the impact on the cutting quality. 4. Casting bed notch sensitivity is lower, because the bed in transportation and processing and other links, there will be an inevitable unexpected gap, cast iron bed due to the material characteristics, there will not be any change due to the gap, so as to further improve the overall stability of the machine. Whether casting or welding, there is a thermal process. In this case, there must be residual stress inside the structure after cooling. Residual stress can make the geometry of the machine in an unstable state, which is obviously not allowed for the machine like a mother machine. In terms of technology, the casting machine body is usually given aging treatment after casting. The welded bed is then subjected to stress relief annealing to eliminate the threat of these residual stresses before being processed into the bed product.  The casting bed has good stability, high cost and long life, causing trouble: wood mold → sand mold → pouring → forming → removing the head → heat treatment → natural aging (at least 3 years, but more than 10 years)→ artificial aging → planing → forceps → high-frequency quenching → grinding → testing.
