Unstable conditions and long overhangs often lead to vibration, poor thread surfaces or even fractures during thread milling processes. With the TC630 Supreme orbital thread milling cutter, Walter
is introducing the first solid carbide thread milling cutter on the market with DeVibe anti-vibration technology.
Incorporating an anti-vibration land on the flank face into the design, the tool is stabilised during machining which suppresses vibration. The patent-pending DeVibe technology ensures excellent operational smoothness and enables usable lengths up to 4xDN, which is ideal for small threads, long overhangs, unstable conditions or difficult materials.
Also in these difficult areas of machining, creating and maintaining dimensional accuracy is desirable and this is where the cutter’s overall design and geometry delivers. With only one row of cutting edges engaged at any one time, tool deflection is addressed and the thread remains cylindrical. The moderate number of teeth also enables a high feed per tooth, enhancing the wear resistance already created by the carefully selected cutter substrate and coating.
The Supreme milling cutter for blind-hole and through-hole threads has a broad application range that covers all ISO materials up to 48HRc. Metric thread sizes from M1.6 to M20 are in the standard program, while also in the range are cutters for metric fine pitch threads, UNC, UNF and STI UNF. The latter is primarily suited to aerospace applications.
With the TC630 Supreme, users can take advantage of a range of benefits that the thread mill design delivers, such as a high level of process security and reliability in unstable machining operations. This enables it to be applied to lathes with driven tools, long overhang applications or instances where reliable chip removal is required - even in deeper thread applications where the optional internal coolant (from M5) applies.
Process stability is also assured for high feed processing and fewer cutter radius corrections are required to deliver time savings and stable, repeatable processes. As well as the cutter design and grade already mentioned, a broad product program and tool shank options ensure that it can be used universally. Areas of application include medical engineering, precision engineering, the aerospace sector as well as electronics and general mechanical engineering.
