CHC & CHP Sharpening machine series

July 15, 2016
CHC 840

CHC 840Intended for hook and clearance surfaces of carbide-tipped saw blades, the CHP 840 and 1300 universal sharpening machines with four CNC-controlled axes are suitable for the complete machining of all commonly found tooth geometries, according to Vollmer of America.

In one cycle, the 840 and 1300 also machine saws with an axial angle and group toothing. A motorized hook and clearance angle adjustment automatically allows the rapid switchover from hook to clearance surface. The adjustable grinding barrel for chip breaker machining ensures more flexibility in the machining of circular saws for metal cutting.

Software for negative hook angle geometries and chip breaker machining is standard. In addition, the machine can be equipped with an optional hollow face grinding device for machining hollow face saws.

The CHP series is principally suitable for workshop-oriented sharpening of circular saw blades for cutting wood, aluminium, plastic and metal. Vollmer machines can be universally used in saw mills, by sharpening services and for small-batch manufacturing.

The Vollmer CHC 840 and CHC 1300 machines are the two "flexible sisters" of the CHP series. Specifically conceived for the particular requirements of sharpening services and saw mills, the CHC series is designed for sharpening carbide-tipped circular saws economically. Also fitted with four CNC-controlled axes, the CHC series machines are suitable for the complete machining of all commonly used tooth geometries in one cycle and, like the CHP, can be equipped with a hollow face grinding device.

  • circular saw

    circular saw

    Cutoff machine utilizing a circular blade with serrated teeth. See saw, sawing machine.

  • clearance


    Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • sawing machine ( saw)

    sawing machine ( saw)

    Machine designed to use a serrated-tooth blade to cut metal or other material. Comes in a wide variety of styles but takes one of four basic forms: hacksaw (a simple, rugged machine that uses a reciprocating motion to part metal or other material); cold or circular saw (powers a circular blade that cuts structural materials); bandsaw (runs an endless band; the two basic types are cutoff and contour band machines, which cut intricate contours and shapes); and abrasive cutoff saw (similar in appearance to the cold saw, but uses an abrasive disc that rotates at high speeds rather than a blade with serrated teeth).
