What is a diamond turning spindle?

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. 

What are the advantages of a diamond turning spindle?

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. 

What types of materials can be machined using a diamond turning spindle?

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. 

What is the maximum speed capability of your diamond turning spindles?

Typically, smaller spindles are C. 12,000 - 15,000 rpm. Larger diamond turning spindles are 3,000-8,000 rpm.
