DDJYL-A-B Integrated Dynamic Static Pressure Spindle

Parameters

Speed: 800-2500rpm

Spindle rotation accuracy: ≤ 0.0005mm

Applicable machine tools: vertical grinder, guide rail gantry grinder

Features: high precision, high rigidity, high service life, high bearing capacity, high anti vibration

Any component on the pump station must first remove the high-pressure oil inlet hose joint. After replacing the component, the oil circuit will circulate for 15-20 minutes before connecting the oil inlet pipe to the grinding head. This ensures that the spindle oil entering the grinding head is ultra clean spindle oil that has been finely filtered. This can extend the service life of the dynamic and static pressure spindle

The dynamic and static pressure spindle is a wear-resistant spindle supported by a dynamic and static pressure oil film. It combines the advantages of dynamic and static pressure spindles while avoiding their disadvantages. It will have broad application prospects in high-precision CNC machine tools. Wide applicability: Suitable for high-precision, high-efficiency, heavy-duty, wide grinding wheel and other fields

Technical parameters and characteristics of dynamic and static pressure grinding head

Within the range of cutting conditions:     spindle should work normally and there should be no abnormal noise.

The radial jump of the main shaft is ≤ 0.001mm, and the axial displacement is ≤ 0.001mm

The spindle speed is related to the shaft diameter. A larger shaft diameter results in a lower speed, while a smaller shaft diameter results in a higher speed. The speed range is 800-5000/min

Oil model: No.2 spindle oil

The oil supply pressure of the hydraulic station is 1.8-2.5MPa, and the main shaft can work normally

When installing a regular grinding wheel, the linear speed should be ensured to be ≤ 60 meters per second to avoid safety accidents
