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).
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.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
Consider these alternatives when conventional drilling can't do the job.
