UNIVERSAL CIRCULAR GRINDING MACHINE OF HIGH PRECISION WITH CNC WITH A ROTARY WHEEL HEAD AND A MOVABLE RECTANGULAR TABLE OSH-660.3.AF3
DESCRIPTION
The machine is designed for external and internal grinding of cylindrical and conical surfaces with end faces of rotation bodies made of tool steels with stepped and curved profiles.
DESIGN ADVANTAGES
- The wheel head has three spindles: two spindles for external grinding and end grinding, and one for internal grinding. For internal grinding operations, a high-speed electric spindle at 63,000 rpm is used.
- Rotation of the wheel head in the horizontal plane and longitudinal movement of the table is carried out by linear actuators.
- Processing parameters: grinding length - up to 1000 mm, maximum external diameter-340 mm, internal grinding processing length-200 mm, maximum diameter – 250 mm.
- Processing of parts on the machine is carried out in automatic mode with control from the SINUMERIK-828D CNC system of Siemens.
- The machine is equipped with an active control device to ensure accurate measurement of the workpiece diameter to be processed.
