High-productivity and optimised changeover times, maximum stiffness, best vibration damping, thermal stability and low maintenance.
These are the defining features of Estarta, the most complete family of centerless grinders.
Every detail is important when handling wheels up to 650 mm wide, grinding workpieces up to 250 mm in diameter with up to 110 kW power:
Oversized ball screws
Twin-grip spindles
Extra clamping in the regulating wheel head
The combination of a cantilever spindle for the grinding wheel and twin-grip for the regulating wheel gives you the best of both worlds.
Changing workpieces has never been so fast
Choose from a wide range of accessories for changing workpieces at the push of a single button:
Automatic workrest blade clamp
Automatic height positioning
Automatic taper adjustment
Motorised wheel cover opening
And much more
Can you imagine never having to worry about oil waste?
Forget about yearly oil waste and reduce your environmental footprint and running costs.
Natural granite machine base
The substitution of all hydraulic elements with high efficiency electric actuators
No chiller needed for our linear motors
The first Estarta was manufactured in 1947
75 years later, it is still the industry benchmark for centerless technology.
It is a perfect combination of tradition and the avant-garde:
Tight tolerances
High grinding speed
Fast changeovers
Environmentally sustainable
Up to 70% reduction in non-productive dressing time
Wheel conditioning was never so easy, fast and safe.
Simultaneous dressing of both wheels possible
Dressing devices run with linear motors
