CNC cylindrical grinderRequire high hydrostatic pressure spindle to have the following characteristics

Low friction resistance: Due to the high-pressure oil film separating the shaft and bearing under any operating conditions (including when the main shaft is stationary), direct metal contact is avoided, resulting in bearing * resistance, only the viscous force of the main shaft oil itself, inherent longer lifespan, and starting torque close to zero, achieving a more energy-efficient effect

High rotational accuracy: Due to the fact that the static bearing is evenly distributed by the entire oil film to bear the external load, it has an average effect on the manufacturing appearance error. Usually, the error caused by the static bearing motion is only one-third of the error of the bearing, so it has high rotational accuracy

High rigidity even under high load bearing capacity and low eccentricity

High pressure flowing spindle oil can be used as a coolant to reduce the temperature rise of the spindle

Good stability, due to the excellent damping effect of the hydraulic film, the workpiece can obtain a better grinding surface

　　CNC cylindrical grinderPreparation before use

Before starting the cylindrical grinder, some preparation work needs to be done to ensure the smooth operation of the grinder. The main preparation work before starting the cylindrical grinder is to check each part:

1. The oil basin in the oil tank should reach the specified oil level height

2. Adjust the tightness of the belt appropriately

3. The protective cover and grinding wheel should be securely fastened, positioned correctly, and the dust-proof felt pad should be tightly adhered

4. Check whether the electrical system (motor, distribution box, safety light, wire, grounding wire) is in good condition, without short circuit, and the surrounding environment should be clean

5. Inject lubricating oil sequentially into the lubrication area specified in the instruction manual of the piston cup foreign grinder

6. Connect the main power supply, start the oil pump and other motors in sequence, pay attention to the operating status, and immediately turn off the power if any abnormalities are found. After inspection and treatment, the vehicle can be started

7. Start the piston cup foreign grinding machine, idle for 3 minutes, check if all parts are functioning properly, if the sound is normal, and if the coolant is unobstructed

8. Before installing the card grinding wheel, it should be prevented from getting damp, and the grinding wheel should undergo a static balance test It is strictly prohibited for the grinding wheel to have cracks

9. When installing the card grinding wheel, a paper pad of 0.5-1.0mm should be placed between the grinding wheel and the pressure plate, and evenly fastened with a wrench. It is not allowed to use an extended pipe for fastening to prevent the grinding wheel from expanding and cracking
