Internal Cylindrical or “ID Grinding” involves grinding straight or formed holes in a rotating, machined workpiece. Superabrasive and Conventional Wheels are widely used in the internal grinding of all types of hard, tough, and abrasive materials within precise tolerances and surface finishes. South Bay has a range of Resin Bond, Metal Bond, Vitreous Bond, and Plated Diamond & CBN Mandrels and Wheels in stock that are well suited for ID and Jig Grinding applications. In addition, custom specifications and wheel geometries can be manufactured to meet your requirements. Wherever they can be introduced and utilized, “Superabrasives” will pay big dividends with respect to process control, overall part quality, and cost.
