ELITE GBT 851 DUO. MACHINE BASIS.

The ELITE model GBT 851 DUO is our CNC grinding machine for the flanks for circular saws with tungsten carbide teeth. It is similar to the GBT 850 DUO but with 2 more CNC axis that enables the machine to be fully automatic in every teeth geometry adjustment. Counting a total of 6 CNC axis.

This version is equipped with double grinding wheel and its operation is CNC with 10,1" color LCD screen. It allows a precise and fast grinding of the flanks of the teeth to manufacture carbide circular saws or repare newly welded teeth when doing teeth replacement.

The optimal cabin design ensures an easy saw blade adjustment.


ELITE GBT 851 DUO. HOW IT WORKS

Easy to use control panel

Panel%20de%20control

All the functions of the buttons are explained in the buttons with ilustrations. Every button is intended to do a single task, so you know what to expect from a button press.

The control panel with LCD screen allows the 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 movement of the tooth feeding pawl
  • Number of teeth
  • Broken teeth

Up to 7 teeth/minute in triple-chip tooth

You can go fast when it is needed!
All the movements has been optimized to reduce dead times.

Grinding wheel rotation speed variable from 5.00 to 9.000 RPM

Our machines include the variable frequency drive as a standard feature, so you can adjust grinding wheel speed at the optimal value and also reduces energy consumption.

Easy maintenance

Armario eléctrico

The electrical cabinet is organized in a clean manner, so the maintenance is easy when you need to do it.
