Product Overview
This precision mini lathe is designed for various processing jobs, including turning, drilling, threading, and cutting on round bar materials. It features a DC motor-driven spindle with variable speed from 0 to 2500 RPM.
Technical Specifications
- Power: 550W (brush motor)
- Spindle Speed: 0-2500 RPM
- Center Distance: 350mm
- Chuck Diameter: 100mm (Three-jaw chuck)
- Spindle Taper: MT3
- Tailstock Taper: MT2
Setup and Adjustment
Before operation, clean off any grease from the machine. Ensure the three set screws on the chuck are tight and that the chuck rotates freely by hand. Move the feeding direction selector to the middle position.
Operation and Maintenance
Chuck Replacement: Place a cloth or wood on the bed way under the chuck to prevent damage if dropped. Loosen the three set screws to remove the chuck.
Jaw Replacement: Jaws are internal or external. Mount them in ascending order (1-2-3) and remove in descending order (3-2-1). After assembly, rotate to the smallest diameter to ensure they are well-fitted.
Carbon Brush Replacement: Remove brush covers on the motor cover and the right bottom side of the speed controller.
Gear Mounting
Gears can be replaced according to the gear list provided in the manual. After replacement, ensure the gears are properly interlocked with each other.
Troubleshooting
If the machine fails to start, check the following: 1. Ensure power supply voltage matches the machine (110V or 220V). 2. Check if the voltage is stable. 3. Check if the fuse is broken. 4. Ensure the motor is working. 5. Open the control box to check for loose wiring. 6. Verify the correct starting sequence was followed.
