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.


  • Rigid Tapping--Sometimes You Need A Little Float

    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.

  • Tool Considerations for High Speed Cutting

    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?

  • Rolling Threads Has Advantages

    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.
