Polygon Turning/Threadmilling Catalog Page

Polygon attachments are mounted on the cross slide or main tool slide and cut flats with a cutter that is synced to the part. This is called flat generating. One flat or multiple flats can be made with different ratios and cutters. For example, to create the six flats on a hexagonal part such as a hex bolt, you would use a cutter with three inserts spaced equally 120 degrees apart at a ratio of 2:1. The polygon attachment's cutter is spinning at twice the rate of the part in your screw machine. Watch the video below for a demonstration of this process.

Thread milling attachments use an advanced spindle technology to achieve the lowest possible run out. They also have a base plate system that allows exact taper adjustment which allows this attachment to be mounted on older machines that might be worn or out of square. Thread milling in steel can be achieved using carbide cutters, great for very narrow threads and non ferrous materials that do not roll well. See our threadmilling page for more information.
