Kyocera SGS Precision Tools Expands Z-Carb HPR Series
Kyocera SGS Precision Tools has expanded the Z-Carb HPR series of high-performance end mills for titanium and stainless steel. The expansion includes 320 tools in fractional diameters ranging from 1/8" to 1" and in metric diameters ranging from 6 to 25 mm. The five-flute roughing end mills are said to achieve high metal removal rates while still providing a smooth surface finish. The specialized five-flute design is engineered for increased productivity over three- and four-flute end mills.
Fifty-nine of the expanded items are coated with Ti-Namite-M (TM) and feature new corner radius options. The TM coating promotes higher removal rates in difficult-to-machine materials like titanium, according to the company. Another contingent of the expanded items are coated with Ti-Namite-A (TA), which improves removal rates in materials like stainless steel.
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.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
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.
