Centerless Grinding Centerless grinding is an effective process used for finishing a parts surface which saves time and money. MLG provides precision tolerances to meet your specific requirements. Straight or stepped shafts can be ground concentric to the centerline of the part.
Centerless Grinding. Centerless Grinding is a machining process that removes material from the outside of a cylindrical item through the method of abrasive cutting in order to achieve the desired diameters, smoothness and roundness. The concept is relatively simple. The workpiece is fed between two wheels rotating at different speeds.
In the grinding process of centerless grinder, there are two grinding wheels: guide wheel and grinding wheel. The guide wheel drives the cylindrical workpiece to rotate on the pad iron, and the grinding wheel plays a grinding roll on the workpiece.
Centerless Technology offers some of the most advanced cylindrical grinding equipment in the industry. Our latest acquisition, the KELLENBER VARIA UR 175/1000, boasts a fully programmable B Axis capable of complex multidiameter grinding as well as internal grinding.
Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained. On traditional OD machines, the work is held between centers or chucked and rotated against the faster spinning grinding wheel by an external motor usually located in a workhead.
