Designed for the universal sharpening of tungsten-carbide-tipped (TCT) circular saw blades with diameters up to 840mm and 1,300mm respectively, the CHP840 and CHP1300 grinding centres from Nottingham-based Vollmer UK Ltd (www.vollmer-group.com) have four CNC axes for the accurate grinding and polishing of virtually all tooth geometries — in a single cycle.

Moreover, these machines feature a multi-function hand-wheel and incorporate programs for use in the aluminium-, plastic-, wood- and metal-cutting sectors.

These compact machines feature a 10in LCD colour display, a full enclosure for maximum safety and noise suppression, and a robust vibration-free platform for optimal sharpening performance.

The four axes allow the complete machining of all commonly used tooth geometries — including axial angles and ‘group toothing’ geometries.

The CHP machines also feature oscillation grinding as standard, as well as motor-driven hook and clearance angle adjustment, thereby ensuring high rates of material removal and the flexibility to switch rapidly from face grinding to top grinding.

For the metal-cutting market, the CHP840 and CHP1300 incorporate a powerful motor with a variable grinding speed for optimised machining parameters.

Machines specifically for the metal-cutting sector also feature an adjustable grinding barrel for machining chip-breakers (the software accommodates negative tooth-face geometries and chip-breaker machining as standard). The control can store up to 4,000 programs for TCT and HSS saw blades.
