CHC 840

The Vollmer CHC 840 and CHC 1300 are high-performance CNC grinders built for the precise sharpening of carbide-tipped circular saw blades-perfectly suited for sawmill applications. With four fully CNC-controlled axes and advanced oscillation grinding, the CHC series machines all standard tooth geometries in a single cycle, including saws with axial angles or group toothing. Whether you're sharpening saws for softwood, hardwood, plastic, or composite material, the CHC provides unmatched consistency and flexibility.

CHC 840 handles blades up to 33" (840 mm) while the CHC 1300 expands capacity up to 51" (1300 mm)

Both models are designed for low maintenance with no hydraulic systems, a fully enclosed cabinet, and automatic central lubrication-making them ideal for sharpening rooms looking to reduce downtime and increase output.

Burton Mill Solutions can help configure the ideal CHC machine for your sharpening workflow.
