High-Performance JIS Taps

January 01, 2011

Emuge Corp. has introduced a new line of High Performance JIS Taps for tapping applications at companies manufacturing products with Japanese-specified standards. The new Emuge JIS Line includes a selection of taps and cold-forming taps. Shank diameter and square dimensions are in accordance with Japanese standards, and all Emuge JIS taps are uniquely designed to produce threads with a JIS Class 2 tolerance.

"As part of our continued global expansion, Emuge wants to recognize and offer key standards, such as the unique specifications for Japanese automotive manufacturing. Manufacturers who need to produce threads according to Japanese standards now have another choice for taps," said Mr. Peter Matysiak, President of Emuge Corp. "Further, to provide for manufacturers located in Japan, Emuge has recently opened a branch office in Yokohama City, Japan."

Emuge's expertise and excellence in tapping technology are inherent in their new high quality JIS TapEmuge JIS Taps include a variety of geometries and styles that will produce threads in a broad range of materials from steels, stainless steels, cast and non-ferrous, to titanium and titanium alloys, nickel and nickel-base and cobalt-base alloys. The surface of the taps are treated with titanium carbonitride or titanium nitride coating for a long tool life.

For efficient chip evacuation and maximum lubrication, Emuge JIS taps are available with an internal coolant-lubricant supply exiting through the tap or in the flutes. New Emuge JIS Taps are offered in designs for both short-chipping and long-chipping material and through-or blind-hole applications. Emuge's JIS line also includes a tap ideally suited for producng threads in cast iron, as well as abrasive cast iron with vermicular graphite.

JIS Taps are optimized for use on automatic lathes, multi-spindle machines or CNC machines. JIS Cold forming taps for the chipless production of internal threads in blind- or through-holes are also available. The cold forming taps feature excellent stability, especially with small thread sizes. Emuge JIS Taps include sizes ranging from M 5 x0.8 to M 12 x 1.75 in metric coarse and from M 10 x 1.25 to M 20 x 1.5 in metric fine, in straight-flute, spiral point, slow- and fast-spiral flute configurations. The taps have advanced coatings to suit material and tapping applications.

  • abrasive

    abrasive

    Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.

  • alloys

    alloys

    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • blind-hole

    blind-hole

    Hole or cavity cut in a solid shape that does not connect with other holes or exit through the workpiece.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • flutes

    flutes

    Grooves and spaces in the body of a tool that permit chip removal from, and cutting-fluid application to, the point of cut.

  • shank

    shank

    Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

  • stainless steels

    stainless steels

    Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.

  • tap

    tap

    Cylindrical tool that cuts internal threads and has flutes to remove chips and carry tapping fluid to the point of cut. Normally used on a drill press or tapping machine but also may be operated manually. See tapping.

  • tapping

    tapping

    Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.

  • titanium carbonitride ( TiCN)

    titanium carbonitride ( TiCN)

    Often used as a tool coating. See coated tools.

  • titanium nitride ( TiN)

    titanium nitride ( TiN)

    Added to titanium-carbide tooling to permit machining of hard metals at high speeds. Also used as a tool coating. See coated tools.

  • tolerance

    tolerance

    Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
