Sumitomo Electric Carbide Inc. introduces a new general purpose face mill that reportedly provides substantial cost savings to consumers. The new 45 degree DGC cutter accepts double-sided square and octagon inserts that reduce user's initial cost while increasing productivity in general purpose to rough milling.
Cost efficiency is highlighted with the DGC octagon inserts. The DGC significantly reduces the initial investment by having 16 cutting edges available at 3mm depths of cut. Square inserts offer 8 cutting edges at 6mm depths of cut while providing an elite surface finish.
The patented ZX coating strengthens square and octagon DGC inserts to extend tool life while increasing wear resistance. When interrupted cutting, the ZX coating enhances the tool life and cost efficiency of the DGC to provide machinists with an ideal surface finish.

- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- 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.
- wear resistance
Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
