By combining the PCD milling cutters developed and patented by LACH DIAMOND with the PCD chip breaker patented by Audi AG, this process reportedly assures and guarantees controlled and economic machining of aluminum. This idea led to the concept of offering this advantage to all aluminum processors, especially to the automobile accessory industry. This is now possible after conclusion of a licensing agreement with the Audi AG, the owner of the patent.

With immediate effect LACH DIAMOND PCD Monoblock milling cutters will be offered not only with the featured »Cool Injection« for direct cooling through the PCD cutting face, but also alternatively with the chip breaker »Plus«. By combining both advantages, an ideal combination is available for the innovative machining of aluminum: »Cool Injection-Plus«.

By the now-possible close pitch, the maximum number of teeth leads to a considerable longer service life, extreme high cutting values, increased infeed, fine surface quality and component accuracy, according to the company. With high performance cutting (HPC) cycle time reduction of over 50 percent is possible as well.

Related Glossary Terms

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • milling


    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • pitch


    1. On a saw blade, the number of teeth per inch. 2. In threading, the number of threads per inch.

  • 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.
