Machine Base The heavily ribbed box-type base is made of Meehanite casting, providing excellent rigidity to ensure machine stability. Optimum distance between the guideways offers excellent table support to increase Z axis positioning accuracy and repeatability. Work head The sturdy rigid-designed workhead equipped with precision bearings is electronically controlled giving variable spindle speeds. Workhead swivels 90°counterclockwise to 30°clockwise for various grinding operations. A combination live and dead-type spindle allows for quick changeover from center to chuck operation or vice versa. A dual oil seal and cover prevent coolant seepage into the workhead. Tailstock The design of the tailstock is both rigid and robust. Housed in a Meehanite case body, the hardened nitralloy steel sleeve is designed to carry a MT4 center for G32A/G38A. Movement of the sleeve is adjusted by a knob to give a light or heavy load.

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
