PMG Series
For the past 25 years, the Supertec PMG universal grinder series has maintained an irreplaceable position in the fiercely competitive global market. Over time, it has continuously demonstrated remarkable performance improvements. In 2023, with the full integration of the ANCA Motion next-generation controller, it has achieved a significant milestone by fully embracing Industry 4.0 and opening the door to ESG (Environmental, Social, and Governance). In recent years, the Supertec PMG series has also witnessed its perfect flexibility and long-term stability in semiconductor processing.
Description
SUPERTEC’s PMG series (Pax π series) is a line of universal cylindrical grinders for the external/internal diameter composite grinding process of long shaft workpieces like crankshafts. It offers versatility and can handle small to large production quantities, as well as low-volume and high-variety production.
Wheel Head
PMG series (Pax π series) uses the wheel head (Automatic B-axis) with 2 OD wheels and 1 ID wheel. With the PMG CNC series, complex grinding operations such as external grinding, external taper grinding, end face/shoulder grinding, and internal grinding can be completed in a single setup. It brings reduced cycle time, operation costs, and improved accuracy.
- CNC controlled wheel head (B-axis) with servo motor output 1.2 kw
- B-axis (±2.0”)PR or (±5.0”), can be equipped with either Heidenhain or Fagor encoder.
- OD spindle motor output 5HP, equipped with CE certified safety cover
- OD wheel size (LHS) Ø405x 50 xØ127 mm
- OD wheel size (RHS) Ø305 x 25 xØ127 mm
Special Coolant System design
Coolant flows through the whole machine via a nozzle system during the grinding operation. Extra heat will be taken away to prevent transformation, and ensure the accuracy of performance. Grinding chips will be washed away by the current to keep the cleanness of the machine
This series offers a long history of reliability and versatility in universal cylindrical grinding. It is suitable for many industries, including automotive, semiconductor, machinery, and hydraulic, pneumatic, and electronic motor manufacturing.
