Centerless grinding with a "workpiece on the fly”
Centerless grinding involves the work-piece being simultaneously machined and guided on its generated surface. The line contact on a grinding wheel forms the grinding line, the workpiece lies flush with the regulating wheel and is held in place from below by a guide rail. During grinding, the center of the workpiece lowers as its diameter is reduced through abrasion. This causes the work-piece to migrate towards the regulating wheel. JUNKER’s electronic control system compensates for this position change by tracking the grinding wheel so that pre-cise machining is guaranteed at all times. Centerless cylindrical grinding is also the ideal solution for workpieces that are dif-ficult to hold due to their shape or small dimensions. |
