MVB850%28F%29

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.
