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.

  • Rolling Threads Has Advantages

    With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.

  • Choose The Best Drill Point Geometry

    The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.

    Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
