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.
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.
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.
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.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
