Confirm the details before selection

Workpiece & process

Provide a drawing, material grade, hardness where applicable, incoming condition and required geometry. Published results must be read with their original test conditions.

Machine & tooling

Confirm the model, mounting dimensions, interfaces, abrasive or carrier specification, coolant and required documents. Request a dimensioned drawing for the configuration being quoted.
