Video: Custom Workholding for Tool Regrinding

This shop uses a simple toolholding device on a machine meant for unattended tool production to regrind tools that already have their precision geometry.

Tri-State Tool Grinding in Cincinnati, Ohio, has a CNC tool grinder with a workpiece carrier intended for production grinding of carbide blanks. The small shop wanted to adapt this carrier for unattended regrinding of tools that already have the precision geometry.

The shop’s solution illustrates a point worth noticing now and again—namely, the extent to which a machine shop is routinely an inventor. Frequently, that invention takes the form of fixtures and other in-house workholding for machining centers, but this video shows it applied to the creation of a workholding device used for holding tools during regrinding.
