2. Safety Instructions
Always prioritize safety when operating the mini metal lathe. Failure to follow these instructions may result in injury or damage to the equipment.
- Wear Personal Protective Equipment (PPE): Always wear safety goggles or a face shield to protect your eyes from flying debris. Consider wearing gloves, but ensure they are tight-fitting to avoid entanglement with rotating parts.
- Work Area: Operate the lathe in a well-lit, clean, and organized workspace. Ensure adequate ventilation. Keep children and pets away from the operating area.
- Secure Workpiece: Always ensure the workpiece is securely clamped in the chuck before starting the lathe. A loose workpiece can be ejected at high speed.
- Tool Selection: Use only sharp, appropriate cutting tools for the material being worked on. Dull tools can cause excessive force and lead to accidents.
- Power Connection: Ensure the power supply is correctly connected and matches the specified voltage (110V-240V). Disconnect power before performing any adjustments, maintenance, or when the machine is not in use.
- Avoid Overloading: Do not attempt to process materials beyond the lathe's specified capacity or apply excessive force, as this can damage the motor or components.
- Emergency Stop: Familiarize yourself with the location of the power switch for quick shutdown in an emergency.
- Children-Proof Design: While the machine incorporates children-proof design and safe fillet processing technology, adult supervision is always required when children are near the equipment.
3. Setup and Assembly
The ZHRUI Mini Metal Lathe is designed for straightforward assembly. While main components like the motor case and headstock are pre-jointed, some modular connections may be required.
- Unpacking: Carefully remove all components from the packaging. Verify that all parts listed in the packing list (typically included with the user manual) are present.
- Base Placement: Place the machine base (315mm x 200mm x 17mm) on a stable, level, and clean workbench.
- Component Connection: The machine utilizes a dovetail structure for connecting various parts. Align and secure the headstock, tailstock, and slider assemblies onto the machine bed. Ensure all connections are firm and stable. The connection blocks are fixed by square nuts to prevent loosening from vibration.
- Chuck Installation: Install the appropriate chuck (3-jaw or 4-jaw) onto the headstock spindle. Ensure it is securely fastened, typically by a hexagon nut, to maximize clamping tightness.
- Tool Post Setup: Mount the turning tool clamping jaw onto the big slider. The big slider features three parallel dovetail slots to facilitate tool movement and holder installation.
- Power Connection: Connect the provided AC adapter to the lathe's power input and then to a standard 110V-240V AC outlet. The 3C quality assured transformer provides over-current, over-voltage, and over-heat protection.

4. Operating Instructions
This section details the operation of your ZHRUI Mini Metal Lathe for various machining tasks.
4.1. Basic Operation
- Workpiece Clamping: Securely clamp your material in the 3-jaw chuck (max diameter 50mm) or the optional 4-jaw chuck (max diameter 60mm for irregular shapes). Ensure the workpiece is centered and held firmly.
- Tool Positioning: Mount the appropriate turning tool in the tool post. Adjust the tool height to be on the center line of the workpiece. Use the hand wheels for precise positioning along the X and Z axes. The hand wheels feature 0.02mm scale lines for high precision.
- Power On: Turn on the main power switch. The motor will reach its maximum speed of 12000 rpm. The built-in fan ensures ultra-quiet operation and effective cooling.
- Material Removal: Slowly advance the cutting tool into the workpiece using the hand wheels. Take light cuts, especially with harder materials, to avoid overloading the motor and ensure a smooth finish.
- Monitoring: Continuously monitor the cutting process, chip formation, and tool condition. The safety guard device protects against tool impact.
- Power Off: Once machining is complete, retract the tool, turn off the power switch, and allow the chuck to stop rotating before removing the workpiece.
4.2. Advanced Features
- 4-Axis Rotation (A-axis): The Rotary Miniature Lathe supports 4-axis operation (X, Z, Z1, A axes). The A-axis can rotate from -90 degrees to +90 degrees with a positioning accuracy of 2.5 degrees, enabling complex angle feed machining in coordination with the Z1 axis.
- Increased Machining Diameter: Intermediate blocks can be added under the motor box, tailstock, and lathe tools clamping jaw to enlarge the machining rotary diameter and practical usage.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ZHRUI Mini Metal Lathe.
- Cleaning: After each use, clean the lathe thoroughly to remove chips, dust, and debris. Use a brush or compressed air. Avoid using solvents that may damage the anodized surfaces.
- Lubrication: Periodically apply a light machine oil to the lead screws, slides (dovetail structures), and other moving parts to ensure smooth operation and prevent wear.
- Inspection: Regularly inspect all screws, nuts, and connections for tightness. Re-tighten any loose fasteners, especially the square nuts on connection blocks, to maintain stability and processing accuracy.
- Tool Care: Keep cutting tools sharp and free of rust. Store them properly to prevent damage.
- Surface Treatment: The electroplating and ink-jet anodized surfaces are designed for lasting rust-proof appearance. Clean them gently to preserve their finish.
6. Troubleshooting
This section addresses common issues you might encounter with your mini metal lathe.
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not power on. | No power supply; faulty power adapter; tripped circuit breaker. | Check power connection and outlet. Ensure power adapter is functioning. Reset circuit breaker if necessary. |
| Workpiece slips in chuck. | Workpiece not clamped tightly enough; chuck jaws worn or dirty; workpiece diameter too large. | Ensure workpiece is fully seated and chuck is tightened using the hexagon nut. Clean chuck jaws. Verify workpiece is within specified diameter (max 50mm for 3-jaw, 60mm for 4-jaw). |
| Excessive vibration or wobble during operation. | Loose connections; unstable workbench; unbalanced workpiece; dull cutting tool. | Check and tighten all assembly screws and connection blocks. Ensure the lathe is on a solid, level surface. Balance workpiece if possible. Sharpen or replace cutting tool. |
| Poor surface finish on workpiece. | Dull cutting tool; incorrect cutting speed/feed; excessive depth of cut; vibration. | Sharpen or replace cutting tool. Adjust cutting parameters. Reduce depth of cut. Address vibration issues as above. |
| Slider movement is stiff or jerky. | Lack of lubrication; debris on slides; overtightened gibs. | Clean slides and apply machine oil. Check for debris. Adjust gibs if applicable (refer to detailed assembly guide if provided). |
