INTRODUCTION

The new and miniaturized CNC internal Grinding Machine from PALMARY features build-in spindles design, man-made mineral machine bed for more stability, minimize its space, and an elegant appearance combined with advanced CNC control and interactive screen operation. The all new series will bring internal grinding technology into a new era.

 

FEATURES

Man-made mineral machine bed

The high rigidity and stable man-made mineral machine bed could provide the smooth machining requirement and being the basic of accuracy.

The minimum floor space

The clients’ factory land capacity was increased for the machine has small machine bed design which only same as B1 paper size. Further, it’s easy to equip the automatic loading system.

Built-in spindles

The high efficiency bearing built-in spindles are used on both grinding wheel spindle & work spindle which offer the high accuracies grinding performance.

High-speed grinding efficiency

Both X & Z axes equip with linear servo motors which provide high-speed grinding activity and shorten the cycle time. Further, the digital readouts put on both axes for high-speed precision efficiency.
