Video: Hard Pocket Milling
Relieved end mills and pre-machining of corners are two important considerations for accurate pocket machining in hard steel.
This tutorial from video contributor Todd Schuett discusses some of the keys to accurate milling of pockets in hard steel. The specific application involves milling of slide pockets at Allcraft Mold in Schaumburg, Illinois. The video explains the importance of relieved end mills and pre-machining of corners, and also gives various other tips for precise pocket machining.
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.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
The right choices in tooling and technique can optimize the thread turning process.
