Hydrostatic Electrospindles
In 2004 OMLAT spa studied and realised several electric spindle applications for grinding, with the technical characteristic of having hydrostatic bushes instead of ball bearings.
This concept (an oil cushion with approx. 60 bar pressure) makes it possible to obtain a dynamic rigidity that is more than three times that obtained with the mechanical solution (ball bearings) and consequently guarantees a very high quality finish.
These spindles have been constructed for tangential grinding machines, for the large size bearings sector and for the rolling cylinder grinding sector.
Both asynchronous and synchronous motors have been used able to fully meet the project requirements regarding performance (power and rotation speed), together with a very low vibration level, appropriate for high-precision machining.
With the high rigidity obtained by this system, last generation tools can be used to full advantage, ensuring the best output and long life.
