Our best estimate for a cnc grinding machine in this class — not a quote from Vollmer. Configuration moves it a long way.

Overview

The Vollmer CHD270 grinds the teeth of circular saw blades from 80 to 840 mm in outside diameter, on blade bodies up to 14 mm thick and with tooth pitches from 6 to 180 mm. Those three ranges decide what fits: small, fine-pitch blades at one end and large, coarse-pitch blades at the other, all on the same machine. The bore has to be 10 mm or larger.

Vollmer's table separates the work by tooth surface. The rake face and the flank face are each ground with a wheel on a 32 mm bore, while the hollow face is ground with a pin on a 6 mm shaft. Hook angles run from -30° to +40°, and clearance angles from +5° to +45°. When a hollow face is ground the hook angle range is narrower, -10° to +25°. Cutting edges up to 20 mm long can be ground, a hollow face up to 15 mm, and relief grinding on the top up to 40 mm.

Bevels are covered on three surfaces. The flank face can be bevel ground up to 60°, and the rake face and the negative rake face up to 30° each. The row for size of tooth difference is marked optional, so a shop that sharpens blades whose teeth differ in size should confirm with Vollmer that the option is on the order.

The site requirements are small for a machine with this diameter range. Vollmer lists a weight of approx. 3,000 kg, a connected load of approx. 5.8 kVA, an air supply above 5 bar and a coolant container of approx. 140 L. No spindle power, grinding wheel diameter or axis speed appears in the table, so cycle time cannot be estimated from these figures alone.

Strengths & Limitations

Strengths

One machine covers saw blade outside diameters from 80 to 840 mm and tooth pitches from 6 to 180 mm
Hook angles from -30° to +40° and clearance angles from +5° to +45° take in negative-rake and steep positive-rake teeth
Hollow-face grinding up to 15 mm, done with a grinding pin on a 6 mm shaft
Bevel grinding up to 60° on the flank face and up to 30° on both the rake face and the negative rake face
Modest services: approx. 5.8 kVA connected load, air above 5 bar and a coolant container of approx. 140 L

Limitations

Blades larger than 840 mm in outside diameter or thicker than 14 mm do not fit
With a hollow face the hook angle range shrinks to -10° to +25°
Size of tooth difference is listed as optional, not as part of the base machine
Cutting edge length is limited to 20 mm, which excludes teeth with a wider cutting edge

Best For

Sharpening circular saw blades from 80 to 840 mm in outside diameter Hollow-face teeth with a hollow of up to 15 mm Bevelled tooth tops up to 60° on the flank face Saw service work with mixed tooth pitches from 6 to 180 mm

Frequently Asked Questions

01 What size saw blades does the Vollmer CHD270 take?

Outside diameters from 80 to 840 mm, with a bore from 10 mm and a blade thickness up to 14 mm. Tooth pitch can be anywhere from 6 to 180 mm, and the cutting edge can be up to 20 mm long.

02 Which tooth angles can the CHD270 grind?

Hook angles from -30° to +40° and clearance angles from +5° to +45°. Bevel grinding goes up to 60° on the flank face and up to 30° on the rake face and on the negative rake face. Relief grinding on the top is possible up to 40 mm.

03 Can the CHD270 grind hollow-face teeth?

Yes. Vollmer lists a hollow face of up to 15 mm, ground with a grinding pin on a 6 mm shaft. The hook angle at the hollow face is limited to -10° to +25°, which is narrower than the -30° to +40° available on a plain rake face.

04 What grinding wheels does the CHD270 use?

The rake face wheel and the flank face wheel both mount on a 32 mm bore. Hollow-face grinding uses a grinding pin with a 6 mm shaft. The table does not give wheel outside diameters, so those need to be confirmed with Vollmer when ordering wheels.

05 What does the CHD270 need on site?

A connected load of approx. 5.8 kVA and compressed air above 5 bar. The coolant container holds approx. 140 L and the machine weighs approx. 3,000 kg, so floor loading and a coolant fill of that size are the main things to plan for.
