Process for producing milling cutters by equipping with macro grains of abrasive materials, such as silicon carbide

摘要

In the process for producing milling cutters by equipping with macro grain of hard, sharp-edged abrasive materials, the machining properties of this coarse grain at high rotational speed of the milling cutter are utilised, as a result of which the cutting blades usually used can be replaced. Hand-held milling devices with cutting blades are difficult and inaccurate to control for wood machining and hold a high risk of accidents by the appliance breaking out at changes in grain. The equipping of the milling cutters with coarse, sharp-edged grain, on the other hand, permits a versatile shaping of the milling cutter, a neat and risk-free operating console and a high lifetime in the event of sand or metal being included in the wood. Milling cutters with macro grain equipping thus provide ideal prerequisites for use in tree surgery.
