Blade evolution on show at MACH

At the forthcoming MACH exhibition at the Birmingham NEC next month, Vollmer (Hall 20, Stand 160) will be giving an exhibition debut to two machines for the processing of saw blades and cutting tools: the Loroch Evolution K850-M and Vgrind 360.

Incorporating a 19” touch-screen CNC that is comparable to a smartphone configuration, the Loroch Evolution K850-M allows blades to be programmed in minutes. Suitable for processing HSS, solid-carbide and friction saw blades, the machine has a direct-drive grinding wheel configuration which reduces power loss and eliminates undesired vibration that can impact blade quality.
Capable of automatic processing, saw blades can be loaded from 130 to 520 mm diameter in random order, while manual loading will accommodate blades up to 850 mm diameter. To achieve the automated concept with differing bore sizes, bore-reducing rings can be used to create a common bore diameter. With eight CNC axes, just one clamping flange is required for blades from 130 to 850 mm diameter.
For manufacturers of carbide drills and milling cutters, the Vgrind 360 features two vertically arranged spindles and five harmonised CNC axes that achieve interpolation with short travel distances for both the linear axes and swivel ranges. Capable of processing cutting tools up to 200 mm diameter, the machine has a number of automation options for lights-out production that will be demonstrated at the show.
