Machine Control Technologies Inc. offers the 5-axis MCTSamatic 5000I CNC PCD grinder, with 8-axis freedom of movements, for producing PCD-tipped inserts and rotary tools. It is built on a steel base with 6"-thick granite top for damping and equipped with an automatic measuring system.
The rotary axis can swivel 270 degrees around the rotary center to provide a wide grinding angle. The grinder has built-in macro programs for producing radii, chamfers and relief angles. The conversational programming menu enables users to fill in the tool grinding information without needing expensive grinding software to run the machine, according to the company.
The machine costs $138,000 without the optional autoloader, which can load different workpiece sizes and shapes.

- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- conversational programming
Method for using plain English to produce G-code file without knowing G-code in order to program CNC machines.
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.
- polycrystalline diamond ( PCD)
polycrystalline diamond ( PCD)
Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.
Space provided behind the cutting edges to prevent rubbing. Sometimes called primary relief. Secondary relief provides additional space behind primary relief. Relief on end teeth is axial relief; relief on side teeth is peripheral relief.
