Workpiece size: it is a long and deep hole, from 500mm to 3000mm
Surface roughness requires: Ra0.8
Customers use vertical machine tools. The customer wants to dress stainless steel 17-4, 718 and is currently using abrasive hone stone sizes of 8x8x100mm 10x10x100mm, but it is too slow and can’t achieve a fine surface roughness quickly, it takes about 8 hours or more to hone 0.3mm stock.
Before trying a diamond stone from Japan, the price of this diamond stone is very high, so we can not use the diamond.
After sharing some grinding parameters and cases with the customer, we advise using CBN hone stone, 8x8x100mm, grit B181, and getting a trial order quantity of 20 pcs
