Ddjyl-a-b integrated dynamic and static pressure spindle

Time:2021-11-17 11:40:48Seo:


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 vibration resistance

when replacing any parts on the pump station, the high-pressure oil inlet hose connector must be removed first. After replacing the parts, the oil circuit circulates for 15-20 minutes before connecting the oil inlet pipe to the grinding head, so as to ensure that the main shaft oil entering the grinding head is super clean main shaft oil after fine filtration, which can prolong the service life of the dynamic and static pressure main shaft

dynamic and static pressure spindle is a wear-free spindle supported by dynamic and static pressure oil film. It combines the advantages of dynamic and static pressure spindle and avoids its disadvantages. It will have a broad application prospect in all kinds of high-precision CNC machine tools. Wide application range: suitable for high precision, high efficiency, heavy load, wide grinding wheel and other fields

technical parameters and characteristics of dynamic and static grinding head

within the range of cutting conditions:    The main shaft shall work normally without abnormal noise

radial runout of main shaft ≤ 0.001mm, axial runout ≤ 0.001mm

the spindle speed is related to the shaft diameter. If the shaft diameter is large, the speed is low, and if the shaft diameter is small, the speed is high. The speed range is 800-5000 / min

oil model: No. 2 main shaft oil

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

when installing ordinary grinding wheel, ensure that the linear speed is ≤ 60ms to avoid safety accidents
