MECHANICAL OVERHAUL:
Ndjdsuxfu Njpfx Am Hoa
- Complete machine refurbished according to Kellenberger measurement protocol
- Repainted

New hydraulic power unit:
- Improved temperature control (oil cooler)
- Energy-saving: Only one pump, not running continuously!
- Pressure monitoring
- Monitoring of water content in hydrostatic oil
(early detection of bellows damage)
Hydrostatic ball screw drive in X-axis
- Wear-free, as no contact during operation
- No loss of accuracy, even during prolonged operation under full load at max. speed
- Frictionless at low speeds
- No reversal backlash when changing direction
- Transmits minimal rotational movements
- No stick-slip effect at low speeds
- No fluctuations in friction torque due to ball circulation
- Higher axial stiffness than ball screws
- Significantly better damping, resulting in improved workpiece surface and tool life
- No oscillations due to ball circulation
- Suitable for high speeds and accelerations
- Cost-effective alternative to linear motor with higher accuracy and much lower heat generation
- Significantly lower power loss and no issues with chips sticking to permanent magnets
- Much lower cooling requirements than linear motors

Electrical overhaul:
- Brand new, modern CNC cylindrical grinding control with BEMA cylindrical grinding interface
- Newly built control cabinet
- New drive technology
- Replacement of all electrical wiring, BERUS pressure switches, etc.
- New absolute linear scales in X and Z axes
- New absolute encoder (for B-axis)

Control:
The grinding software consists of a basic license and various options that can be enabled depending on machine equipment.

Basic software:
- External and internal oscillation grinding
- External and internal plunge grinding
- External and internal face oscillation grinding
- External and internal face plunge grinding
- External and internal taper oscillation grinding
- External and internal radius grinding (radius dressed on the wheel)
- Semi-automatic oscillation grinding
- Workpiece...
