Grinding

Double‐Rough Pinch Grinding Cuts Cycle Time in Half

This alternative to customary pinch grinding uses two roughing wheels to decrease cycle times for blank preparation of carbide cutting tools.

Turn-Mills

For CNC Multitasking Machines, Why Part Along Y?

Newly designed tooling takes advantage of a multitasking machine’s Y-axis motion to more effectively perform parting-off operations compared to conventional X-axis processes.

Horizontal & Vertical Lathes

Will Transmission Manufacturers Turn to Out-Of-Round Turning?

Out-of-round turning can be an efficient alternative to profile milling and grinding for polygon couplings that could replace traditional spline connections in automotive transmissions.

5 Facts About Thread Rolling

Unlike subtractive processes, thread rolling does not remove material but instead moves and molds ductile metals quickly and precisely into the thread form using a cold-forming process. Learn more about thread rolling and tooling advances here.

Single & Multi-Spindles

Speed, Process Control Combine in Refreshened Multi-Spindle Platform

A screw machine design known for its high production speed — but also its finicky nature to set up and run — has evolved to provide computer control, better accuracy and improved repeatability.
