ELITE GBT 850 DUO. MACHINE BASIS.
The ELITE model GBT 850 DUO is our CNC grinding machine for the flanks for circular saws with tungsten carbide teeth.
This version is equipped with double grinding wheel and its operation is CNC with LCD screen. It allows a precise and fast grinding of the flanks of the teeth to manufacture carbide circular saws or carry out teeth replacement
ELITE GBT 850 DUO. HOW IT WORKS
Easy to use control panel
The machine includes a led cabin light as standard.
The control panel allows selection of left or right rotation of the sharpening stone.
The grinding wheel motors with a direct motorized spindle system are adjustable from 5,000 to 9,000 RPM for optimum sharpening quality with minimal stone wear. It is driven by a frequency inverter.
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.
Programming and operation of the machine
Homing of the axis
Grinding wheel rotation speed variable from 2.500 to 5.000 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.
Saw diameter from 100 mm.
For grinding the flanks of scoring discs or portable machines
Allows indexing of any type of tooth pitch.
Integrated refrigeration equipment
Allows wet sharpening for better sharpening quality and longer life of the sharpening stone.
It integrates a 200-liter tank with removable grids for easy cleaning.
Clean design and easy access for service or repair of the machine.
The electrical panel is located at the bottom and the mechanics at the top of the machine, protected by an easy-to-open cover.
The electrical cabinet is organized in a clean manner, so the maintenance is easy when you need to do it.
