1.Suitable grinding wheel and grit sizes
Resin-bonded diamond wheels and metal-bonded diamond wheels are suitable for grinding ceramic chip bonding tools. Choose the appropriate diamond wheel grit according to the different grinding stages:
Rough grinding: Use a coarse-grained diamond wheel of D46 or D76 for preliminary removal of excess material.
Semi-fine grinding: Use a medium-grained diamond wheel of D20 or D30 to further refine the tool shape.
Fine grinding and polishing: Use a fine-grained diamond wheel of D7 or D10 to ensure surface finish and accuracy.
2.Determine grinding parameters
Reasonable grinding parameters (such as grinding speed, feed speed, grinding depth, etc.) have a significant impact on the final processing quality. The recommended parameters are as follows:
Grinding speed: According to the material hardness and grinding wheel characteristics, it is usually controlled at 20-30 m/s.
Feed speed: Keep it at 0.01-0.1 mm/s to avoid excessive feed speed causing tool breakage.
Grinding depth: Each grinding depth should be less than 0.02 mm, and the grinding depth should be reduced during the fine grinding stage to ensure surface quality.
