New from Sumitomo Electric Carbide Inc., the SumiMill GOALMILL Milling Cutter finishes cast iron with exceptional accuracy. The GOALMILL imparts fine surface finishes through the use of tangentially mounted inserts accompanied by easily adjustable axially mounted wiper inserts.
Each insert offers eight indexes when using single-handed cutters. Four indexes can be used on the periphery pockets, and flipping the insert on its side allows for four more indexes in the finishing cartridge. A total of 12 indexes can be used when employing both right and left hand cutters.
GOALMILL cutters are available for roughing (less than 50 Rz) semi-finishing (less than 18 Rz) and finishing (less than 12.5 Rz). Left-handed cutters are made to order.

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 cutter
Loosely, any milling tool. Horizontal cutters take the form of plain milling cutters, plain spiral-tooth cutters, helical cutters, side-milling cutters, staggered-tooth side-milling cutters, facemilling cutters, angular cutters, double-angle cutters, convex and concave form-milling cutters, straddle-sprocket cutters, spur-gear cutters, corner-rounding cutters and slitting saws. Vertical cutters use shank-mounted cutting tools, including endmills, T-slot cutters, Woodruff keyseat cutters and dovetail cutters; these may also be used on horizontal mills. See milling.
Metal-removing edge on the face of a cutter that travels in a plane perpendicular to the axis. It is the edge that sweeps the machined surface. The flat should be as wide as the feed per revolution of the cutter. This allows any given insert to wipe the entire workpiece surface and impart a fine surface finish at a high feed rate.
