The REKORD 500 CNC is a high-precision grinding machine designed for sharpening, re-toothing, chamfering, and fully restoring metalcutting circular saw blades with outstanding accuracy. Using CBN or diamond grinding wheels, the machine delivers exceptional surface finish and fast cycle times — even when handling worn, damaged, or variable-pitch blades.
This advanced unit is built for HSS, friction, and solid carbide circular saw blades, making it ideal for saw doctors, metal fabrication shops, manufacturing facilities, and high-production environments across Australia.
The machine can be operated confidently by non-skilled users thanks to its intuitive CNC interface. Programming is guided through a large 10” touch-screen, with tooth geometry and profile automatically calculated to DIN standards, and easily fine-tuned when needed.
A high-pressure coolant system ensures consistent cooling and stability during grinding, while filtration systems maintain coolant cleanliness and extend system performance.
The REKORD 500 CNC includes full capability for HSS circular saw blades, including:
Sharpening
Re-toothing
Chamfering
Variable tooth pitch grinding
DIN 1840 tooth forms (A, AW, B, BW, C)
Tooth geometry modification
Precision clamping for rigid, chatter-free grinding
It supports HSS blades from 150–650 mm (with optional fixtures allowing 50–150 mm diameter blades).
This makes it suitable for tube mills, steel processing, and high-speed cutting applications.
With a fully digital CNC control system, operators can:
Program tooth geometry individually
Adjust rake and clearance angles
Modify pitch and tooth depth
Store up to 99 complete working cycles
Monitor live time-remaining for cycle completion
Perform automatic tooth form calculation with easy overrides
The CNC platform ensures consistency across batches, reduces operator error, and dramatically improves workshop productivity.
Beyond HSS, the REKORD 500 CNC can sharpen and re-tooth solid carbide circular saw blades using diamond wheels.
Optional software unlocks:
Full carbide tooth profile grinding
New tooth creation
Grinding of matched pairs of blades
Geometry correction for specialised tooth forms
Cylindrical grinding cycles for blades with broken teeth
This makes it a highly versatile investment for workshops working with high-wear carbide tooling.
The machine is designed for unattended or minimal-attendance operation thanks to:
Automatic lubrication
Automatic coolant filtration
Automatic tooth indexing
Automatic chamfering adjustment
Fully enclosed safety cabin
“End cycle” indication lamp
Teleservice remote support (optional)
These features streamline workflow and allow the machine to run efficiently in production settings.
