CNC Internal Grinding Machines

OD (outside diameter) grinding shapes and finishes the external surfaces of a workpiece, while ID (internal diameter) grinding works on internal bores and holes. Many machines, like the Overbeck and Danobat models WSM offers, combine both capabilities in a single platform for versatile precision machining.

These machines are widely used in mold and die making, automotive component manufacturing, aerospace, and precision mechanics shops. Any industry requiring tight-tolerance bores, such as bushings, spindles, and hydraulic components, relies on internal grinding for dimensional accuracy and surface quality.

Modern CNC internal grinders like those from Overbeck and Danobat can achieve tolerances within a few microns, along with excellent roundness and surface finish. Exact capability depends on machine configuration, wheel selection, and workpiece material, so consult our team for application-specific specs.
