Owing to new processing technologies, 15 years ago, Lach Diamond pioneered to place ;a chipbreaker guide step three-dimensionally as a chipbreaker into the diamond layer of a PCD insert. From this the company developed several variations for their chipbreaker program for the machining of nonferrous metals, especially for aluminum. This became a key element in series and mass manufacturing. The Titan is the patented >>chipbreaker Type IS<< (US Patent 6.315.502).
With its active chipbreaker and stable cutting edge it was developed mainly for the rough machining of thick-walled, solid components with a SI content below 7 percent and is also suited for interrupted cuts. With cutting speeds from 800 to 2500 m/min. and feed rates from 0.1 to 0.3mm/rev. depth of cut, up to the maximum utilization of the cutting width from to 3 to 5mm are possible.
For thin walled, unstable components the identically constructed chipbreaker, the >>chipbreaker CO<< is available.
Related Glossary Terms
Groove or other tool geometry that breaks chips into small fragments as they come off the workpiece. Designed to prevent chips from becoming so long that they are difficult to control, catch in turning parts and cause safety problems.
- depth of cut
depth of cut
Distance between the bottom of the cut and the uncut surface of the workpiece, measured in a direction at right angles to the machined surface of the workpiece.
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- 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.
