Related Glossary Terms
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.
Machining a bevel on a workpiece or tool; improves a tool’s entrance into the cut.
- coated abrasive
Flexible-backed abrasive. Grit is attached to paper, fiber, cloth or film. Types include sheets, belts, flap wheels and discs.
Removal of undesirable materials from “loaded” grinding wheels using a single- or multi-point diamond or other tool. The process also exposes unused, sharp abrasive points. See loading; truing.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- 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.
The new CC-GRIND-STRONG grinding discs from PFERD offer a modern, high-performance and ergonomic alternative to conventional resin-bonded grinding wheels. The unique design combines the strength and long service life of its ¼” resin-bonded abrasive backer with the comfortable operation and fine surface finish of its layered coated abrasive discs.
This innovative product results in highly aggressive removal rates, with noise and vibration being reduced by as much as 50 percent, and dust reduced by as much as 70 percent, compared to conventional grinding wheels.
CC-GRIND-STRONG grinding discs are suitable for use on steel in applications such as mill scale removal, weld dressing, chamfering and deburring. They are available in 4 ½ in. and 5 in. diameter sizes with both 7/8 in. unthreaded bore and 5/8-11 quick-change threaded hub.
