Kyocera Precision Grooving System Gets a New Stable Insert Grade
Kyocera Precision Tools has expanded the insert lineup of the GBA grooving system with the PR1625 grade designed for grooving steel and stainless steel. PR1625 is designed to provide hardness and toughness during groovin operations, incorporating a stable carbide base material and Megacoat Nano coating for resistance to wear when grooving light as well as heavily interrupted cuts.
The GBA grooving system features inserts with three usable cutting edges. These inserts are available in three grades: PR1215 for general purpose grooving, TN620 for surface-finish-oriented grooving, and PR1625 for interrupted cuts. The tool’s GM chipbreakers are designed to maintain smooth chip control and provide a more stable groove in a range of shallow grooving applications.
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.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
