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.

Launched to coincide with the arrival of its latest deburring, edge rounding and finishing machine – the 22 series WRBW – the Timesavers online virtual showroom provides access to all the information customers may need, including video tours of each machine.

While face-to-face meetings have proved difficult, if not impossible during the COVID-19 pandemic, this online portal provides potential and existing customers with the information they need to move towards a solution for efficient sheet metal processing.
Although the complete Timesavers product range is available to view in the online showroom, the current focus is on its latest development, the 22 series 600 WRBW, which combines all of the technological and mechanical developments in the larger 32 and 42 series deburring machines, such as a uniform result, even wear of the tooling, high production capacity, and industry 4.0 functionalities in a 600 mm wide platform. The 22 series WRBW is now the company’s most compact rotary brushing machine, and is said to deliver premium Timesavers deburring, rounding and finishing results.
Suitable for customers with smaller production demands and associated budgets, the 22 series WRBW is constructed with a vacuum belt to transfer parts through the first abrasive belt to remove burrs. Then, processing by the four rotary brushes is performed to round external and internal edges (and remove laser oxide skin if specified), with a second belt providing the surface finish requirements to deliver fully deburred and rounded parts. The machine’s arrival marks the completion of the Timesavers RB range for premium deburring and rounding at every budget and capacity.
