Requirements For Machining Accuracy Of CNC Tool Grinding Machine
Tool grinding machine for machining accuracy requirements
BT-150N CNC tool grinding machine the requirements for machining accuracy must consider from three perspectives, not just from a unilateral perspective. The following are for accuracy requirements.
1. Grinding machine manufacturing angle: Whether it is a tool grinder or a hob grinder, the linear axis measuring system is equipped with a HEIDENHAIN grating ruler, which forms double insurance together with the encoder. From the structural point of view, the tool grinding machine now uses a long workbench. Matching the structure of the grinding wheel library, on the one hand, can effectively ensure the balance in the long tool grinding process. On the other hand, the coincidence of the grinding wheel rotation center and the grinding point also greatly improves the grinding precision.
2. Matching attachment angle: In addition to the standard workpiece probe, the tool grinder can also equip with a second probe - the original station for the grinding wheel can measure online. That is, the grinding wheel does not need to disassemble and mounted on the workpiece shaft. Instead, measurements can be made at the original station of the grinding wheel. The biggest advantage of this optional accessory is that it avoids the problem of repeated positioning caused by manual disassembly and can better ensure the grinding accuracy.
3. The right angle: Every company has always attached great importance to the after-sales service for users, and has invested a lot of manpower and resources in training and aspects. Only the first-line operators can truly grasp the rules of machine tool use. In order to maximize the advantages of machine tools and achieve high-precision production goals. Only a staff member can have a clearer understanding of the maintenance and maintenance of the machine tool so that the high-precision tool grinding machine can have a longer life.
Grinding method of tool grinding machine milling cutter
with the attachment, the hobbing cutter can ground. Through the inner hole of the mandrel and the hobbing cutter, you only need to know the inner and outer diameter of the hobbing cutter, so you can customize the tooling you need. Fixtures solve your problem of grinding hobbing cutters. Demina below introduces the specific methods and operating methods for grinding hobbing cutters.
1. Place the hobbing cutter on the mandrel and lock the hobbing cutter on the 50HC attachment.
2. For the knife, adjust the angle of the 50HC attachment, specifically according to the angle of the hobbing cutter.
3. Start grinding the end face of the hobbing cutter and adjust the feed amount to start grinding.
4. Grind one side of the hobbing cutter, then replace the other one and repair it in turn.
Grinding milling cutter with a tool grinder
1. The diameter of the milling cutter must be determined. If you want to grind the 8MM end mill, use the 8MM collet and lock the cutter to the 50D sleeve.
2. Set the angle and swing the milling cutter sleeve slightly 4° (the bottom angle of the milling cutter is between 2°-6°)
3.BT-150N universal tool grinder Start grinding the bottom surface. For example, a 4-edge milling cutter, align the milling cutter with the grinding wheel. Complete the tool setting step and then grind the bottom angle of the milling cutter, finish grinding a blade and then replace the other cutting edge is polished in turn.
4. Grind the center of the cutter to escape the angle, swing the sleeve to about 10 °. And then grind the center escape angle of each milling cutter.
5. Grinding the milling cutter second clearance angle in turn.
6. Grind the side edge of the milling cutter, against the spiral groove of the milling cutter, align the grinding wheel, and push the sleeve to grind the spiral side edge of the milling cutter.
