Emuge’s JIS line of high-performance taps is designed for Japanese-specified standards. Shank diameter and square dimensions are in accordance with those standards, and the taps are designed to produce threads with a JIS Class 2 tolerance.
A variety of tap geometries and styles produce threads in a range of materials including steel, stainless steel, cast iron, nonferrous materials, titanium, titanium alloys, nickel, nickel-based alloys and cobalt-based alloys. Tap surfaces are treated with titanium carbonitride or a titanium nitride coating to increase tool life. For efficient chip evacuation and maximum lubrication, the taps also are available with an internal coolant-lubricant supply exiting through the tap or in the flutes.
The taps are offered in designs for both short-chipping and long-chipping material, and through- or blind-hole applications. The line also includes a tap designed to produce threads in cast iron, as well as abrasive cast iron with vermicular graphite. The taps are optimized for use on automatic lathes, multi-spindle machines or CNC machines. Cold-forming taps for the chipless production of internal threads in blind- or through-holes also are available.
The taps range in size from M 5 × 0.8 to M 12 × 1.75 in metric coarse and from M 10 × 1.25 to M 20 × 1.5 in metric fine, straight-flute, spiral point, slow- and fast-spiral flute configurations.
Modular Tooling Lines Enable Shop Standardization
Sandvik Coromant says that its modular CoromantEH, CoroTurn SL and Capto tooling lines enable the selection of optimized tooling assemblies to suit all applications using a smaller inventory of standard items.
