Tungaloy’s CeramicSpeedMill Improves Productivity When Machining HRSAs
CeramicSpeedMill, from Tungaloy, is used for milling heat-resistant superalloys (HRSAs) at elevated feeds and speeds.
The CeramicSpeedMill from Tungaloy is designed for milling heat-resistant superalloys (HRSAs) at elevated feeds and speeds. Two standard ceramic grades are available. TS200 is a universal grade for finishing while TS300 is designed for descaling and other roughing applications. The cutter body is available in a bore (shell mill) style offered in diameters of 63 and 80 mm (2.5" and 3.0").
The TS200 and TS300 grades — made with SiAlON ceramics — have a close-pitch cutter design, enabling milling of nickel-based superalloys at cutting speeds of over 500 m/min. (1,640 sfm), with even greater feed rates possible during HRSA milling, a common aerospace part application.
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.
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?
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.
