Integrated One Piece casting Design

PSGC, PSGO, and PSGP models are all first precision ground before final hand finishes scraping.

The slideway lengths are equal to table lengths, insuring table free from torsion and floatation.

Excellent Features for absolute Precision Grinding

The surface of longitudinal table ways and saddle ways are all hand scraped by experts to ensure high accuracy and to get perfect contact patterns between the matching surfaces. High rigidity, heavy loading capability, and lowest twist deformation, all yield maximum productivity with the highest surface finished and accuracy maintained.
Grinding Spindle:
1. The high precision high rigidity spindle is of a cartridge-type design, which provides easier access and services when maintenance is needed
2. Multiple high-precision anti-friction axial and radial bearings are utilized specifically for absolute minimal play and run-out.
3. A special type of grease-for-life bearing lubrication is accurately applied and sealed in the house for long production hours of trouble-free grinding.
4. Spindle run-out is tested at better than 0.0025mm (0.0001”) T.I.R.
5. The spindle is quiet and vibration-free

Stress-Relieved Main Casting:

All components of the main machine casting, such as base, table, saddle, column, etc are all annealed TWICE with particular attention to remove all metallurgical stress.

Performance: Hydraulic System: Extra Low Noise

1. Two single-acting hydraulic cylinders are anchored at very specific positions with their piston rods to enhance rigidity and stability. It creates a very stable motion and eliminates table floatation.
2. A specially designed hydraulic system, in consideration of preventing excessive heating of hydraulic oil and reducing table reversal shock, results in an extra smooth table movement.
3. The hydraulic tank and pumping unit are separated from the main machine body to provide the following advantages

Prevent the heat of warm hydraulic oil from entering the machine body and the cause of the expansion and distortion which can affect the accuracy of the workpiece finished.

Prevent any vibration generated by the hydraulic pumping system from being transferred off the machine base and the cause of flatter marks on the workpiece.
Hydraulic- type-driven system for table left/right motion provides the smoothest, shock-free step-less feeds for superior workpiece finished. In order to enhance the life of pistons, pumps, cylinders, O-rings, and seals, oil filtration is provided to keep the supplied hydraulic oil free of dirt and grit.
