Walter USA Adds PCD Inserts to Its Cut GX Grooving Series
Walter USA has added polycristalline diamond (PCD) grooving inserts to its Walter Cut GX grooving system. These straight-edge (F1) and full-radius (M1) geometries are designed for grooving in aluminum and titanium alloys, enabling high cutting speed, lengthening tool life and improving surface quality in grooving, parting and recessing operations. The inserts are said to be ideal for aerospace, medical device and automotive applications.
The wear-resistant WDN10 PCD grade provides high hardness, a low coefficient of friction and minimal heat distortion for high-speed machining of nonferrous materials.
The GX24-WDN10 inserts feature chipbreaker geometry, laser-marked ISO and ANSI corner-radius designation, and widths ranging from 0.078" to 0.118" (2 to 8 mm).
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
