STEEL RELIEF GRINDING MACHINE AND SHARPENING MACHINE FOR TUNGSTEN CARBIDE TOOTH CIRCULAR SAWS
HIGHLIGHTS
- 4 CNC axes for automatic work programmable from the control panel
- Programmable tooth pitch
- Steel relief grinder of the saw body, sharpening the top and face of flat teeth
- Easy to use
- Very compact machine with a wide range of disc diameters: from 100 to 850 mm.
ELITE MVB 850. THE CONCEPT.
The ELITE MVB 850 is our flat top and face tooth grinder and steel relief grinding machine for removing steel from the back of the tooth on carbide-tipped circular saws.
For saws from ø100 to 850 mm.
Its special configuration makes it the ideal machine for the sharpening workshop. It not only allows the relief of the saw body, but also allows the sharpening of the top and face of the tooth in the flat teeth geometry. This double function allows for greater use, which implies a much faster amortization of the cost of the machine.
Automatic operation using 4 CNC axes:
B: Tooth angle
C: Feed claw
Z: Sharpening path
X: Sharpening load
The optimal design of the cabin guarantees quick positioning of the saw blade.

ELITE MVB 850. HOW IT WORKS
Easy to use control panel
Easy-to-use control panel with LCD color touch screen that allows programming of the machine. Among the programmable values are:
- Tooth angle programming: The grinding wheel axis will automatically move to the value entered in the program.
- Sharpening path
- Sharpening load
- Sharpening speed
- Tooth pitch
- Indexing speed of the tooth feeding pawl
- Number of teeth
- Broken teeth
Sharpening group
Back-off grinding
You can go fast when it is needed!
All the movements has been optimized to reduce downtime.
Face Grinding
Top sharpening
Sharpening the saw when there are broken teeth
Integrated refrigeration equipment
Machine operates with water-soluble coolant or grinding oil for better sharpening quality and longer grinding wheel life.
Integrated coolant system with 220-liter tank and removable grates for easy cleaning.
Easy access and maintenance
At the back of the machine we find the electrical panel at the bottom and the mechanical system at the top, both protected by their corresponding easy-access panel, which also reduces the total space needed for the machine.

- Grinding wheel holder for face and back sharpening wheels
- 3 mm. feed pawl
- Lighting of the work area using LED lamp
- Device for sharpening saws of equal diameters
- Machine closed by enclosure.
