Specialist Spindles

We are a leading supplier of spindles to original equipment manufacturers in the ultra-precision machining industry

Dicing Spindle 2
A range of spindles are available for applications including contact lens turning, flycutting of optical components, mould grinding and ultra precision face grinding. Spindle designs are continually reviewed and updated to include the latest innovations in high precision technology.

They are manufactured to the highest standards of precision. They are also fitted with low noise motors and are dynamically balanced to within 0.001 gm cm to achieve motion errors as low as 0.05 um peak-peak. Bearing designs are also optimised to give maximum overall spindle stiffness in both radial and axial directions.
Dicing Spindle 1
Spindles are available with foot mounted or plain cylindrical housings. Work or tool holding arrangements are manufactured to suit individual requirements and include air operated chucks, vacuum chucks and collets.

Smaller spindles within the range can reach speeds of 15 000 rpm with air cooling or 25 000 rpm with water cooling. These higher speed spindles are fitted with AC induction motors whilst spindles designed for lower speed machining applications are fitted with DC brushless motors. Encoders are used where accurate speed control or angular positioning is required.

Ultra precision spindles may also be integrated with air slides for applications requiring extreme positional accuracy.
Air Supply Pressure 5.5 Bar
Air Consumption 76 Litres/min
