Lach Diamant has produced a grinding wheel for the tooth-face grinding of circular saw blades that is said to be more cost-efficient while maintaining high precision. The novel carrier system with 3D geometry and extended grinding layer surface is said to allow for effortless grinding of even the smallest tooth gaps.

Until now, the grinding of rake surfaces on carbide-tipped saws frequently fell short of requirements, especially regarding stability and efficiency. According to Lach Diamant, the new DragonFly grinding wheel offers higher in-feeds and feed rates to reduce grinding times, while producing high-quality, even rake surfaces without any ‘buckling’. Indeed, the vibration-absorbing and stable base body presents another innovation.
The DragonFly grinding wheel provides steady and secure grinding of carbide-tipped saws, as one user confirms: “The DragonFly wheel grinds without any problems, is very precise and has a significantly higher lifetime than all previous wheels.”
The DragonFly wheel (for tooth-face grinding) is accompanied by the DragonFly Back Cruiser for back grinding as well as the DragonFly Flank Cruiser for side grinding (from left to right).
DragonFly wheels are based on diamond abrasive technology. For many years, diamonds – preferably polycrystalline synthetic diamonds (PCD) – have been proven superior to carbide in machining. PCD offers high levels of wear protection, allowing users to profit from its elevated hardness.
