Emuge’s ZGF-S-Cut Thread Mills Produces Threads in Exotic Materials

Emuge’s Threads-All ZGF-S-Cut Solid Carbide thread mills feature multiple teeth, a helical flute form and a multi-layer TiAlN T46 coating. The tools can produce threads in exotic materials including Inconels, nickel-based superalloys, Monel, titanium and 420 stainless steel because the heat is carried away during chip evacuation and does not stay in contact with the part. The tools can also be used for producing finer threads for aerospace applications such as engines, connecting rods and landing gear.

The thread mills have multiple teeth, the first acting as a rougher and the next two performing finishing. By dividing functions into three cutting edges, speeds and feeds can be increased and threads can be produced in a single pass, the company says. A 10-degree, left-hand helical flute form and chamfer geometry combine to optimize chip evacuation in the forward direction and add strength to the cutting teeth for better tool life and process security. The tools also have multiple flutes for increased tool strength.

The tools are available in lengths of 2×D, with coolant-fed options starting at ¼" diameter. One tool makes STI threads for both through and blind holes. The thread mills are offered in inch sizes ranging from No.2 or M3 through 7/16 or M10.

The Emuge Threads-all ZGF program of sub-micro grain carbide thread mills encompasses solutions to produce internal threads from No. 0-80 (M1) to 3/4-16. for industries using materials such as stainless steel, titanium and Inconel. Coolant-fed options are available starting at the 5/16" diameter size. Available in 2×D and 3×D lengths in both miniature and standard thread sizes, the Threads-all family of thread mills offer solutions for difficult applications with full bottoming threading within 1 pitch. Threads-all tools provide control over pitch diameter limits including 2B, 3B, 3BG and all oversize variants. Single plane and multiple plane tools are available.
