ESTARTA-175 / ESTARTA-250 - Precision centerless grinding
ESTARTA-175 / ESTARTA-250: precision centerless grinding machine
- Grinding wheel width: up to 250 mm
- Eco-friendly
- Rapid component changeover
Advantages
- The machine with optimized design giving maximum accessibility for different adjustments and machine set up.
- In addition to having optimized rigidity, the machine has been conceived with wheel headstock in cantilever for quick changeover times emphasizing key factors for this design like minimum distance to front bearing or wheel spindle shaft diameter.
- Roller guideway system of the machine with positional control using linear scales, providing two important advantages: extreme movement sensitivity and an environment friendly machine, as the hydraulic equipment becomes superfluous, requiring lower energy consumption and reduced maintenance.
- New damping system in both guiding systems of grinding and regulating wheel slides.
- The combination of these guiding and damping systems yield in maximum precision even in the most severe working conditions.
- Rapid component changeover.
- Automatic taper adjustement.
- Automatic workrest blade locking.
- Automatic workrest blade height regulation.
- At Danobat we have developed our own, unique software for our family of centreless grinders.
- User-friendly software.
- Multiple optional integrated modules & software.
- A solution for the simple development of diamond dressing profiles for both wheels.
- Integrated machine maintenance module.
- Software for automatically generating the regulating wheel profile for throughfeed grinding.
