Diamond tools for delamination-free processing

The machining of GRP and CFRP requires special know-how. Meanwhile, diamond tools – either with diamond or PCD – belong to the standard repertoire for the processing of any type of composite materials.

LACH DIAMOND tools are highly innovative, work with highest precision and increase economic efficiency by a multiple.

Wide variety of uses on all current machines in rotorblade processing: CNC-, robot- and manual milling machines.

Process: face milling of the rotorblade's root end

Solution: PCD face milling cutter

PCD monoblock milling cutters

PCD monoblock milling cutters in process

The LACH DIAMOND high-performance face milling cutter allows maximum face milling accuracy with a low degree of delamination. High feed rates reduce machining times by a multiple. Internal coolant channels ensure longer tool lives. The PCD cutting edges can be resharpend and/or re-tipped with PCD several times.

diameters from 80 to 220mm
for SK or HSK adapters

Process: axial drilling for threaded pins and radial drilling for threaded bushes

Solution: PCD and diamond drills

PCD drills in root end production

PCD brazed solid drills

LACH DIAMOND solid drills with PCD cutting edges allow delamination-free bore entrances and outlets.

The extra-hard cutting material allows maximum feed rates reducing production times by a multiple. Internal coolant channels ensure longer tool lives. The PCD cutting edges can be resharpend and/or re-tipped with PCD several times.
