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.
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.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
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.
