TUNGSTEN CARBIDE TOOTH CIRCULAR SAWS BACK-OFF GRINDER AND SHARPENING MACHINE
HIGHLIGHTS
- 4 CNC axes for automatic work programmable from the control panel
- Programmable tooth pitch
- Back-off grinding of the saw body, sharpening the inside and sharpening the flat outside
- 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 model MVB 850 is our back-off grinder to remove the steel in the back of the tooth in tungsten carbide tooth on circular saws. It can also sharpen the face and the flat top of the teeth as an option.
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 inside and outside of the tooth in the straight 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
Coolant tank
Big coolant tank with capacity up to 220 liters
Back-off grinding
You can go fast when it is needed!
All the movements has been optimized to reduce downtime.
Face Grinding
Fast tooth indexing
Slow tooth indexing
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.
