The inner diameter of thread grinding with better processing economy is usually 10-525mm. The rule of thumb for grinding deep hole internal threads is that the ratio of the length to the diameter of the grinding wheel shaft does not exceed 7:1. The challenge in grinding deep-hole internal threads is the mutual constraint between the helix angle ...
