While CO-type chip breakers only redirect the chips, the new »IC-plus world`s best« chip breaker 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.
LACH DIAMANT can look back on twenty years of experience in the development of PCD chip breakers.
The first CO-type patent was issued on January 26, 1999: A laser cut chip groove for PCD materials.
Practice has shown, however, that chip breakers with a so manufactured chip groove have proven to be only suitable to a limited extent for a process-reliable, controlled chip breaking process of long chipping aluminium alloys.
An active chip breaker was the final solution. It had to show outstanding performance during rough machining as well as fine finishing.
LACH DIAMANT’s PCD »IC-plus« already announced as the »world`s best« chip breaker was born.

As is so often the case, great innovations remain behind closed doors because one does not even get the idea of questioning how many everyday objects are produced. Or have you ever broken your head about how a hair clipper is made?
LACH DIAMANT has faced exactly this topic and again proved the unlimited possibilities of the "contour-profiled"; technology for profile grinding of metal bonded diamond and CBN grinding wheels. Even profile depths of 13. 5 mm with a web width of 0. 5 mm are produced by the Hanau pioneers without any problems and thus make it possible to simplify the production of a hair clipper.
Until now, hair trimmers had to be ground with conventional grinding wheels. The manufacturing process was highly complex as the conventional disc had to be dressed after each stroke to maintain the profile of a hair cutting blade.
The newly developed "contour-profiled"; grinding wheel from LACH DIAMANT consists of a metallic bond matrix which eliminates the need for re-profiling during the grinding process. The entire profile has already been applied to a "mini-contour-profiled"; machine using the "EDG-plus"; spark erosion process developed by LACH DIAMANT. For the user or manufacturer of the hair cutting blade, this means

Monoblock Diamond Milling Cutter for face and square angle milling of all aluminium alloys
Another innovation of LACH-DIAMANT for the automotive and accessories industry ? for greater productivity and economic efficiency
? due to the compact precise design and resulting in a higher number of teeth
? extremely high cutting speeds (HSC) and feeds from 0.05 to 0.20 mm per tooth
? large depths of cut
? suitable for roughing ? finishing ? fine finishing
? no annoying cutting edge adjustments
? maximum tool life and cutting edge stability due to special PCD diamond qualities
? multiple life time of diamond cutting edges ? i.e. production capacity ? through the LACHDIAMANT regrinding service
Other special advantages of the »dia-compact« design:
? no storage of spare parts necessary, as is necessary for traditional insert systems
? integrated coolant supply
? wear-resistant flute for chips
? special dimensions and other types of cutting edges available upon request
In November 2004, when LACH DIAMANT was awarded the Hessian Innovation Prize for a newly developed technology for the cost and time efficient machining of aluminium components with a monoblock diamond cutter »dia-compact«, it was already said "Nothing is more efficient than this...".
However, there was still something more efficient ? as proven by the development of »Cool Injection-Plus», cooling directly via the PCD cutting insert.
Today, maximum tool life, extremely high cutting results and feed rates are taken for granted by leading automotive manufacturers and suppliers due to the use of LACH DIAMANT's monoblock milling cutters.
In addition, perfect surface quality and part accuracy have been achieved ? followed by reductions of cycle time by 50% and more.
The PCD monoblock milling cutter by LACH DIAMANT is completely mounted and balanced, delivered with an adapter of your choice and it can be immediately used on a machine, without adjustments.
