LACH DIAMOND can look back on 20 years of experience in the development of PCD chipbreakers. The first CO-type patent was issued on Jan. 26, 1999: A laser cut chip groove for PCD materials.
Chipbreakers with a manufactured chip groove have proven to be only suitable to a limited extent for a process-reliable, controlled chip breaking process of long chipping aluminum alloys. An active chipbreaker was the final solution. It had to show outstanding performance during rough machining, as well as fine finishing.
While CO-type chipbreakers only redirect the chips, LACH DIAMOND's new »IC-plus world`s best« chipbreaker will already guide chips with a cutting depth (ap) of 0.01 mm. The cutting depth can be increased up to the maximum length of the cutting edge, e.g. up to 5.0 mm maximum for an ISO cutting insert VCMT.

Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- aluminum alloys
Aluminum containing specified quantities of alloying elements added to obtain the necessary mechanical and physical properties. Aluminum alloys are divided into two categories: wrought compositions and casting compositions. Some compositions may contain up to 10 alloying elements, but only one or two are the main alloying elements, such as copper, manganese, silicon, magnesium, zinc or tin.
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.
- 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.
