Special Orders + Services

It is possible for us to offer special dimensions subject to feasibility within the production processes.  We can also supply pre-cut segments from a standard size selection or alternatively to drawing if you have special requirements.

Working with our material

Our Single Layer and Double Sided PCBN can be cut using  Wire EDM (Electrical Discharge Machining) technology and laser technology.  EDM cutting rates and required settings will naturally be different for each type of PCBN due to the varying CBN content.

Our Solid PCBN can only be laser cut and this should be carefully considered when looking at this material.
