Vereco RG 700/8500 CNC Crankshaft Grinding Machine

The VERECO RG 700/8500 NEW CNC grinding machine is designed for the batch production of bench pins and connecting rod pins of crankshafts in a fully automatic cycle, or, for the production of individual parts in manual.

It operates by means of a mobile grinding wheel unit both on the X axis and on the Z axis: this allows the grinding of different diameters in a single positioning of the piece.

Siemens 840D PL CNC Control

The Siemens 840D electronic numerical control system allows you to work manually or automatically, independently managing:

• the transverse movement of the upper grinding wheel wagon (X axis).
• the longitudinal movement of the lower grinding wagon (Z axis).
• the constant speed of the grinding wheel.
• the speed of rotation of the part in work.

REMOTE CONTROL PANEL

• The keypad of the panel is mobile, on sliding guides fixed to the workpiece base, for the length of the piece to be machined.
• From this panel you can control all the functions and movements of the machine.
• Two electronic handwheels allow the micrometric positioning of the two main axes (X and Z).

SOME TECHNICAL SOLUTIONS WITH WHICH THE ETTIFICATRICE IS EQUIPPED:

• dimension detection system with linear transducer (Heidenhain optical line) on the longitudinal axis Z and on the transverse axis X.
• advancement of the longitudinal Z-axis wagon obtained through two motors and two sprockets, managed directly by the Siemens numerical control to eliminate the clearance between the sprockets and the rack.
• hydrostatic support spindle.
• grinding wheel motor mounted on the wagon of the longitudinal axis Z.
• telescopic guards of the longitudinal Z and transverse X axes in stainless steel with first walkable element.
• execution with automatic retraction of the grinding wheel and maintenance of the synchronism of the workpiece heads in case of sudden lack of tension.

STANDARD EQUIPMENT

• Spindle for balancing the grinding wheel.
