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

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.

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.

FAQs
A diamond turning spindle is a precision motorised spindle used in diamond turning processes to manufacture high-precision optical components, moulds, and other parts requiring extremely tight tolerances and surface finishes. It combines the capabilities of diamond cutting tools with air-bearing technology to achieve exceptional accuracy and surface quality.
Our diamond turning spindles offer several advantages, including exceptional precision, low motion error (NRRO), superior surface finish, reduced tool wear, minimised friction and heat generation, extended spindle lifespan, and enhanced stability during machining. These spindles excel at achieving sub-micron level tolerances and producing high-quality optical components.
Diamond turning spindles can be used to machine a wide range of materials, including metals (such as aluminum, copper, and stainless steel), plastics, optical materials (like glass and crystals), and other engineering materials requiring high precision and surface quality.
Typically, smaller spindles are C. 12,000 - 15,000 rpm and are water cooled. Larger diamond turning spindles are 3,000-8,000 rpm, also water cooled.
