and centerless cylindrical grinding machines 5

Design and characteristics of centerless cylindrical grinding machines

General requirements for centerless cylindrical grinding machines for centerless cylindrical grinding:

Maximum stability for high material removal rates, accuracy and throughput is achieved through:

A stable machine bed with high damping and low natural frequency
Height-adjustable, rigid support (workrest blade) for minimized setup time and automatic adjustment of the grinding geometry for simplifying the setup process and ensuring maximum accuracy.
Heavy, rigid main slides for maximum stability and vibration damping
NC-controlled dressing axes for technologically optimized dressing contours
Effective workpiece cooling

The high-performance centerless cylindrical grinding machine Ebert C-3070 meets all general requirements and additionally offers the following features:

Laterally fixed grinding center to simplify workpiece feeding, a prerequisite for machining long workpieces.
Dressing units with separate axes for mechanical copying template and servo contour, for maximum flexibility, precision and service life.
Gearless direct drive of both slides via servo motor and Ø100 mm ball screw for highest precision and rigidity.
Hydrostatic slide system with flow control valves for precise positioning and maximum service life (grinding and regulating slide).
Height adjustment of the workrest blade via servo motor for easy and quick setup of the machine.
Grinding wheel Ø725 mm for maximum service life and productivity, especially with conventional grinding wheels.
100 kW grinding wheel drive power
Machining from small parts in high quantities up to 8-ton bars
Minimized distances to the grinding gap
Compact protective cover
NC contour dressing
constant cutting speed
