7792VXE16 Shell Mill

October 01, 2010

ATI Stellram has introduced the 7792VXE16 high-feed shell mill cutter for machining titanium and nickel- and cobalt-base alloys. The tools are for taking shallow DOCs at high feed rates, and they direct cutting forces axially into the spindle. That reduces spindle wear and enhances machining stability, which is beneficial for modern and older machine tools, the company reports. The cutters accept inserts with four cutting edges, including the company's grade X500, X400, SP6519 and SC3025 inserts.

Related Glossary Terms

  • alloys

    alloys

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

  • feed

    feed

    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • milling machine ( mill)

    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.
