Ghiringhelli M300 SP610 CNC 6 assi

CNC centerless grinding machine Ghiringhelli M300 CNC 420mm wheel widht wheel diameter 610mm maximum grinding diameter 350mm The machine has a very complete configuration and has a gantry loader with controlled axes. The machine ground the outer part of the bearing rings (washers) in an INA factory Siemens brushless motors / drives CNC: Siemens 850 The controlled axes are: - the upper and lower carriage of the pulling wheel - the two axes of the diamond grinding wheel (interpolated) - the two axes of the diamond grinding wheel (interpolated) - the axles of the portal loader - spindle oscillation Operating wheel wheel width max 420mm max dia 610mm peripheral speed max 50 m / sec Motor: 75kW The workpiece holder blade has an NC-controlled locking / unlocking system The spindle has the ability to oscillate axially to cross the grinding marks and perform superfinishing It mounts tailstocks for loading "packed" pieces (they performed external grinding of large bearing rings diameter) The drive wheel has a secondary motor at high revolutions to perform the diamond grinding at a higher speed, reducing the stops for the operation The machine is visible in our warehouse in Gussago BS.

Centerless grinding is a procedure for grinding cylindrical bodies and is used for the mass production of rollers

cylindrical, conical rollers, jet needles, pump pistons, hydraulic sliders, crosses, tips, etc.

During centerless plunge grinding (plunge grinding), the workpiece is ground in one pass

thanks to the translation of the wheel. For this purpose, the grinding wheels and the adjustment discs have a negative profile of the workpiece

to work which is given to them with the aid of a tool.

Through-feed grinding or also through grinding and longitudinal grinding: parts

to be machined proceed uninterruptedly with axial advancement through the grinding gap.
