In fact, the superhard abrasive grinding wheel put forward some requirements on the grinding machine, it is better to grind on the superhard abrasive grinding wheel grinding machine. The main requirements of grinding machine with super hard abrasive wheel are as follows.

1, grinding machine should have high precision, grinding wheel spindle rotation accuracy, radial circular runout should be < 0.001mm, axial circular runout should be < 0.005mm, spindle bearing multi-purpose dynamic pressure bearing or dynamic and static pressure bearing, also can be used static pressure bearing, in order to ensure the precision of precision grinding required processing accuracy.

2, the grinder must have enough stiffness, high stability, small vibration. The stiffness of machine tool will affect the quality of socks and vibration resistance of grinding, which will affect the durability and life of super hard abrasive grinding wheel, and also affect the grinding quality. The general requirement is about 50% higher than the stiffness of ordinary grinding machine.

3, it requires a good feed system, high precision, uniform and stable speed, wide speed range, high speed to ensure productivity requirements, low speed to ensure grinding size, shape accuracy and surface roughness requirements. Generally, the minimum longitudinal feed speed should be O.ML /min, or even smaller, and the minimum transverse feed speed (grinding depth) should be 0.001-0.0005 mm/8t (st^ single stroke). The match between the transverse feed speed of the grinding machine and the size of the grinding particles should be considered for the grinding of the micro sand wheel.

4. The dressing of superhard abrasive grinding wheel should be considered. The dressing of superhard abrasive grinding wheel will involve some special devices, working fluids, dressing parameters, etc., which should make it possible to refit the machine tool.

5. The moving parts of the machine tool, such as the rotary part of the spindle and the part of the feeding movement guide rail, should be reliably sealed to prevent the entry of superhard abrasive causing serious wear.

6. There should be a complete processing system for grinding working fluid to ensure the cleanliness and function of the grinding fluid so as not to affect the roughness of machining surface and prevent the dirty grinding work of the machine tool from causing wear to the moving parts of the machine tool.

7. The ultra-hard abrasive grinding wheel requires small vibration. The machine tool should be placed on the anti-vibration foundation, and corresponding anti-vibration and vibration isolation measures should be taken, such as fine dressing and balance of the grinding wheel, and anti-vibration pad should be added to the contact between the machine tool and the ground.
