Condition: refurbished (used), CN Centerless grinding machine ROSSI MONZA 1500 CN currently being overhauled and fully electrically/electronically retrofitted Siemens electronics with touchscreen, brushless motor on Z (workpiece diameter) and regulating wheel (adjustable RPM), step motor on grinding wheel dressing increment, auto size compensation after grinding wheel dressing Bedjmmqirspfx Afmelp Grinding wheel 350 mm * 610 mm dia This machine can be inspected in our warehouse in Gussago BS Italy Centreless grinding is a procedure for grinding cylindrical bodies and is used for mass production of rollers cylindrical, conical rollers, jet needles, pump pistons, hydraulic sliders, crosses, drills etc. During centerless plunge grinding, the workpiece is ground in one pass thanks to the translation of the grinding wheel. For this purpose, the grinding wheels and the adjustment discs have a negative profile of the piece to work which is given to them with the aid of a tool. The through-feed grinding or also through grinding and longitudinal grinding: pieces to be worked proceed uninterruptedly with axial feed through the rectification gap.
