I.D. or O.D. Sawing and Dicing

“I.D.,” or “inner diameter,” sawing uses a circular, stainless steel blade with a hole in the middle that is coated with diamond abrasive.  In “O.D.” sawing the “outer diameter” of a circular saw blade is coated with the diamond abrasive.  All dicing is a form of O.D. grinding, and basically refers to cutting along both the X- and Y-axes of a part to form small, individual square or rectangular piece.

Although the machines and the design of the blades differ, both I.D. sawing and O.D. sawing/dicing require that the blade and part interface remain cool, lubricated and clean, for greater accuracy, longer tool-life and a smooth, defect-free surface. Combining the correct diamond abrasive and bonding matrix with the correct coolant/lubricant is essential in determining surface finish. Other critical variables include coolant flow rate, flow direction and choosing between a “once-through” or re-circulating system.  If a recirculating system is used, it needs to be properly sized for minimum temperature variation. 

Precision optic and technical ceramic manufacturers worldwide use Intersurface Dynamics’ sawing fluids to maximize yield and enhance equality, especially in high volume applications.
