Blanchard Grinding

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

Large Part Blanchard Grinding Services

You can reduce turnaround time and save on pre-machining 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 materials. We have four large Blanchard Grinders to serve you.

Professionalism at it's Best

Great experience. Withers goes above and beyond to ensure they exceed your expectations.
- James Bradshaw


Withers understood the importance of my position with a press down and meeting customer's expectations. Withers had no warning as to the scope of the work. They worked late and came in very early to ensure that I had the equipment back in 24 hours. There is no other shop in Atlanta with the resources that would make a commitment as what Withers did.
