PMG Series
The Supertec PMG series has been in the market 25 year, the long lasting performance has been proven by the market. The brand new Supertec PMGxA Series is the revolutionary product of Supertec Machinery of 2023, fully achieved Industrial 4.0 by integrating a complete/realtime monitoring system of the entire production line.
Description
Wheel Head
PMG series use the wheel head (Automatic B-axis) with 2 OD wheels and 1 ID wheel, for performing complex grinding operations, such as OD / Taper / ID grinding operations, under one setup to reduce cycle time, operation costs, and get better accuracy performances..
- CNC controlled wheel head (B-axis) with servo motor output 1.2 kw
- B-axis (±2.0”)PR or (±5.0”), can 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 flow through the whole machine via nozzle system during the grinding operation. Extra heat will be taken away to prevent transformation, ensure the accuracy performance. Grinding chips will be washed away by the current to keep the cleanness of the machine
