Blanchard Grinding

Using significantly greater horsepower than other grinding methods, Blanchard grinding (also referred to as rotary surface grinding) removes large amounts of stock quickly, efficiently and more economically. This method adds size versatility, eliminates mismatches and speeds turnaround time on large parts when compared to flycutting; it saves time over surface grinding as well.

You can reduce turnaround time and save on premachining costs by simultaneously Blanchard grinding multiple parts – creating further efficiencies. Multiple part grinding, along with cutting a large, Blanchard-ground blank into smaller parts, provides uniform part-to-part thickness tolerances and surface finishes at a lower unit cost.

Withers Tool, Die and Manufacturing Company offers precision grinding to close tolerances at competitive prices. Surface finish typically will run 63 microinch rms and as high as 32 microinch rms with certain material. We have four Blanchard grinders to serve you.
