Why PCD with »chipbreaker«? Working without »chipbreaker«
Working with dreborid®-»chipbreaker«
Since for weight saving purposes aluminum has been applied to an increasing extent in the automobile and aircraft industry here, the use of so-called forging alloys is advancing.
10 year
s
experie nce in the manufa cturing of PCD »c hipbrea ker«
In comparison to the conventional cast alloys, these alloys have a much higher toughness, with the disadvantage, however, that at cutting, undesired ribbon and thread chips are produced.
On January 26, 1999, the first patent application was confirmed by the German patent office, further applications followed, such as the Europe patents EP 1 023 961 B1, EP 1 023 962 B1 and US patent 6,315,502.
This way unforeseen and unwanted machine shutdowns develop. Damaged tools have to be replaced or, in the best case, large clews of these chips have to be removed from the working space of the machine.
The result of all experiences and developments can be seen in the form of this »chipbreaker« program.
Also in the area of PCD cutting inserts no systems existed up to now, which would avoid with 100% certainty such ribbon and thread chips. LACH DIAMOND, ten years ago took on this problem with great expenditure. Thanks to new processing technologies, such as laser technology, it was possible for LACH DIAMOND, for the first time to put in a chip guide step (three dimen-sional) as a chipbreaker into the diamond layer of a PCD cutting insert.
Cornerstones of this program are the patented »chipbreaker« types CO (with laser cut guide steps) and IS (with fitted active »chipbreaker«). The effectiveness of the »chipbreaker« IS again is once more strengthened by the type IC. In addition to the solidly anchored chipbreaker the type IC is equipped with a laser cut, circular positive chip guide step. This way the cutting force again is decreased and the chip is directed effectively to the »chipbreaker«.
The following shows examples of further »chipbreaker«variations
Note: The manufacturing of the »chipbreaker« is not limited to PCD cutting inserts; please see the information about CBN-DUO cutting blanks with »chipbreaker« for the machining of hardened steels.
