Presentation

ELITE JVC 800 DUO. HOW IT WORKS
Easy to use control panel
All the functions of the buttons are explained in the buttons with illustrations. And 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:
- Roughing phase:
- Infeed
- Total amount to be grinded
- Circular knive rotation speed
- Finishing phase
- Infeed
- Total amount to be grinded
- Circular knive rotation speed
- Fine-finishing phase:
- Time of the fine-finishing operation
- Circular knive rotation speed
Working exemple

Grinding wheel rotation speed variable from 2.000 to 4.000 RPM
Available as an option.
Program for equal diameters included as standard
You can produce circular saw blades at the same diameter as a standard feature.
Easy maintenance
The electrical cabinet is organized in a clean manner, so the maintenance is easy when you need to do it.
