ESTARTA-400 / ESTARTA-650 - Heavy-duty centerless grinding
ESTARTA-400 / ESTARTA-650: heavy-duty centerless grinding machine
The machines in this family are designed for both infeed and throughfeed grinding.
- Grinding wheel width: up to 650 mm
- Eco-friendly
- Rapid component changeover
Advantages
- Looking for maximum rigidity, innovative additional support in the regulating wheel headstock is used thus eliminating the stiffness losses that all the kind of machines has had till now.
- Roller guideway system of the machine with positional control through glass scales, providing two important advantages: a greater movements sensitivity and an environment friendly machine as the hydraulic equipment becomes superfluous, requiring a lower energy consumption and reduced maintenance.
- New damping system in both guiding systems of grinding and regulating wheel slides.
- The combination of this clamping system with mentioned guideway solution guarantees the maximum precision even in the most severe working conditions.
- High speed manufacturing (120 m/s with CBN technology) paying special attention to rigidity and vibration damping.
- Requirements of completely automated manufacturing processes are fulfilled with the incorporation of customized automatic loading systems developed by Danobat, e.g. Integrated gantry or robot solutions as well as different measuring devices: by contact, pneumatic and optical.
- Rapid component changeover.
- Automatic grinding wheelhead opening.
- 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.
