Overview

The Vollmer CHD270 is a CNC circular saw blade and profile saw blade sharpening and service machine — a completely different application from the company's round tool grinding machines. Vollmer is the world leader in circular saw blade sharpening machines, holding a dominant position in this specialized niche that spans woodworking, metal sawing, and composite sawing industries. The CHD270 is Vollmer's primary carbide-tipped circular saw blade grinding machine, designed for both the initial facing and top grinding of carbide saw tips and the servicing (resharpening) of worn carbide-tipped saw blades.

The CHD270 handles saw blades from 60 mm to 840 mm (2.4 to 33 in) in diameter, covering the full range of circular saw blades from small hand-tool replacement blades through large industrial sawing blades used in timber, metal, and composite cutting. The machine grinds both the top face (top clearance angle) and face (hook angle, side clearance) of each carbide tip in a fully automated cycle, indexing the blade through all tips at precise angular increments.

Vollmer's Comfort Control (CC) touchscreen control manages all grinding parameters — tooth pitch, tooth height, top and face angles, and feed rates — through an intuitive interface. The machine's automatic setting capability reduces setup time for new blade specifications, and stored programs enable fast blade-to-blade changeover for resharpening services handling multiple blade specifications per day.

At $150,000-$250,000 new, the CHD270 serves professional saw service centers, furniture and wood product manufacturers with in-house blade maintenance, metal sawing operations, and composite machining shops where blade condition directly affects cut quality and productivity. It competes with Vollmer's own CHF270 (face grinding only) and systems from Loroch and Foley United in the saw sharpening market.

Strengths & Limitations

Strengths

840 mm maximum blade diameter covers the full range from small hand-tool to large industrial circular saw blades
Automatic top and face grinding in one machine eliminates the need for separate top and face grinders
Vollmer's Comfort Control enables fast program recall for repeat blade specifications in blade resharpening services
Vollmer's dominant market position in saw blade sharpening means the most developed software, service, and support network in this niche
Compact and lighter than round tool grinders at 1,800 kg — accessible for smaller saw service operations
Handles variable-pitch blades and special-geometry blades in addition to standard uniform-pitch blades

Limitations

$150K-$250K is a significant investment for a machine dedicated specifically to saw blade sharpening
The CHD270 does not grind round tools, insert tools, or other cutting tool types — it is dedicated to circular saw blades
Vollmer's North American service network for saw blade machines is smaller than their European network
For shops needing only top grinding or only face grinding, the full CHD270 capability may not be necessary
Requires diamond or CBN grinding wheels specific to carbide saw tip grinding — consumable selection is critical

Best For

Professional saw service centers resharpening industrial carbide-tipped circular saw blades for multiple industries Large sawmill and timber operations with in-house blade maintenance programs for wood and composite sawing Metal service centers using carbide-tipped circular saws for steel, aluminum, and copper cutting who maintain blades in-house Furniture and wood product manufacturers running large volumes of circular saw blades who need in-house resharpening capability Industrial blade manufacturers setting up blade grinding capacity for carbide-tipped production and resharpening services

Frequently Asked Questions

01 What types of saw blades does the CHD270 service?

The CHD270 services carbide-tipped (TCT) circular saw blades in wood, metal, and composite cutting applications. This includes wood ripping blades, crosscut blades, combination blades, metal cutting blades, aluminum cutting blades, and fiber-reinforced composite cutting blades. The machine is designed for standard sintered carbide tips — not PCD or diamond-segment blades, which require different grinding or laser processing.

02 How does the CHD270 compare to the Vollmer CHF270?

The CHD270 grinds both the top face (clearance) and face (hook angle) of each carbide tip. The CHF270 grinds the face only. For complete saw blade maintenance including both geometries, the CHD270 is the appropriate machine. The CHF270 is appropriate for operations that primarily service blades requiring face grinding only — more common in metal cutting than woodworking applications.

03 What is the cycle time for resharpening a typical saw blade?

A typical 350 mm diameter circular saw blade with 72 teeth can be resharpened on the CHD270 in approximately 15-20 minutes including both top and face grinding. Larger blades with more teeth take proportionally longer. Setup and program recall for a stored blade specification adds 5-10 minutes. For a professional service center, the machine can process 20-25 medium-size blades per shift.

04 Does the CHD270 require diamond wheels?

Yes, the CHD270 uses diamond grinding wheels for grinding carbide saw tips. Wheel specifications depend on the carbide grade being ground — coarser diamond for initial tip formation (tipping) and finer diamond for resharpening. Vollmer provides application-specific wheel recommendations. Wheel life on carbide saw blade grinding is measured in hundreds of tips; wheel cost is a meaningful operating cost factor.
