Spindle maintenance instructions:

1、 Maintenance cycle: The maintenance cycle for a regular spindle is within 1-2 working days (excluding logistics time)

The maintenance cycle for domestic electric spindles is within 1-2 working days

The maintenance cycle for imported electric spindles is 5-7 working days

2、 Warranty period: 6 months

3、 Maintenance accuracy: dynamic balance up to G1, noise level of 60DB, accuracy within 0.015/300mm, end face runout within 0.005mm

Repair process:

1、 Technological integration of electric spindle

High speed bearing technology: Electric spindles usually use composite ceramic bearings, which are wear-resistant and heat-resistant, and have a lifespan several times longer than traditional bearings; Sometimes electromagnetic suspension bearings are also used, with no contact between the inner and outer rings, theoretically having an infinite lifespan.

High speed motor technology: The electric spindle is a product of the fusion of the motor and the spindle, and the rotor of the motor is the rotating part of the spindle. In theory, the electric spindle can be regarded as a high-speed motor, and its key technology is dynamic balancing at high speeds.

2、 Regular inspection of electric spindle

The axial runout of the electric spindle is generally required to be 0.002mm (2 μ m), and it should be tested twice a year.

The radial runout of the taper hole in the electric spindle is generally required to be 0.002mm (2 μ m), and it should be tested twice a year.

3. The radial runout of the distal end (250mm) of the electric spindle core rod is generally required to be 0.012mm (12 μ m), and it should be tested twice a year.

4. The tightening force requirement for butterfly springs is 16-27KN (taking HSK63 as an example), which should be tested twice a year.

5. The extension distance of the knife rod when loosening the knife is 10.5 ± 0.1mm (taking HSK63 as an example), which should be tested 4 times a year

3、 Electric spindle maintenance

Clean the spindle motor clamp and pressure cap every day.

When using equipment with automatic lubrication function, pay attention to observing the lubricating oil storage in the automatic lubrication oil tank and replenish lubricating oil to the tank in a timely manner.

3. Enter JDTEST to check the status of each signal bit and the motion characteristics of each axis. After confirming the correctness, run continuously in EN3D for 10 minutes. If the work is normal, it indicates that regular maintenance is completed.

The maintenance and testing equipment includes:

1. Ultrasonic cleaning machine. 2. Spindle inspection rod. 3. Spindle dynamic balancing machine. 4. Spindle temperature rise detector. 5. Main spindle running in platform. 6. Spindle noise detector. 7. Spindle vibration meter. 8. Bearing press machine. 9. Bearing heater.

Home service is available in Jiangsu, Shanghai, and Anhui regions.
