Tool Inserts Improve Finish, Production Rate for High-Temp Alloys
Thinbit by Kaiser Tool Co. offers inserts tipped with cubic boron nitride and polycrystalline diamond.
Thinbit by Kaiser Tool Co. offers inserts tipped with cubic boron nitride (CBN) and polycrystalline diamond (PCD). CBN and PCD inserts are available for grooving, turning, face grooving, threading, boring and parting. The inserts are useful in form tools and custom geometries.
CBN-tipped inserts provide an increased production rate, improved surface finish and dimensional control when used on high-temperature alloys such as Inconel, nickel-based alloys and materials with a hardness of Rockwell C-35 or harder. PCD-tipped inserts provide these same benefits when used on nonferrous and abrasive metal such as aluminum, brass and copper.
The inserts fit L-series toolholders and can be used in conventional, Swiss-type and CNC machines. Toolholders are available in square shank sizes from 5/16" to 1¼" and round shank sizes from ½" to 1" with both straight and 90-degree presentations.
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.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
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.
