SPTM EXJ Thread Mill

Scientific Cutting Tools offers the new SPTM EXJ thread mill. The SPTM EXJ is an economical tool engineered for cutting external UNJ threads. It features a single thread profile that is ideal for keeping side-cutting pressure low.

The non-crest cutting design allows maximum flexibility for plated and non-standard threads. SPTM EXJ tools will cut any size external thread of the pitch listed. It is precision ground for maximum concentricity. The tool is available uncoated or with an AlTiN coating.

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
