Relationships of rough grinding and fine grinding
Which step do you think is more important in a grinding process, rough grinding or fine grinding? “Fine grinding” is most selected from our customers. As the final step, they believe fine grinding is protagonist in their job. One of my customers told me a sentence before, “Fine grinding is fine, everything is fine.” However, I do not agree with his thought.
Fine grinding is important, but we cannot ignore the effect of rough grinding. It is the beginning of one project, if we do not control the quality well in first step, it is impossible to make second and every follow step well.
For example, in PCD or PCBN tools grinding. We often meet the issue of large chipping edge in fine grinding process. Generally, the first thing came to mind is changing fine grinding wheel, choose finer grit size, or change current grinding wheel supplier.We tend to ignore the issue in last step. If we get a 0.05mm chipping in rough grinding, how could we reach 0.005mm in next step? Guarantee the chipping edge under 0.02-0.03mm in rough grinding, then we can get 0.005mm cutting edge easily.
When we do a wonderful job in rough grinding, we can get 8 times efficiency improvement in maximum. It decreases lots of time in fine grinding, no need to take much time to remove the big scratches which generates in rough grinding. In conclusion, we say the first step is always hardest, the first step is always important. Rough grinding as the first step in production process, we should complete it well and stable, or we will never get good quality in fine grinding.

Customers use ceramic diamond cylindrical grinding wheels to grind PCD roller tools. At first, the customer was not satisfied with the chipping effect of using a domestic brand grinding wheel. Currently, customers use a resin diamond grinding wheel from a certain European brand to achieve better grinding results, but the cost is relatively high.
A diamond roller is a high-efficiency, long-life, low-cost grinding wheel dressing tool that uses electroplating or powder metallurgy methods to inlay a large number of diamond particles on the surface of a steel roller. It is used for special machine tools and gear grinders for mass form grinding. Rotating at a certain speed (thereby reducing the relative speed between the roller and the grinding wheel) produces grinding and rolling effects on the surface of the high-speed rotating grinding wheel, so that the grinding wheel obtains a sharp working surface that matches the roller profile.
