I. Key Points to Note When Using CNC Lathes
Pre-Operation Inspection and Preparation
Before starting the machine, operators must conduct a comprehensive inspection:
- Verify power and air supply are normal, with stable voltage and adequate air pressure
- Ensure sufficient lubricating oil and coolant, with unobstructed oil and fluid lines
- Confirm tools and workpieces are securely clamped, with fixtures tightly fastened
- Safety guards are intact
- Program and coordinate system are correct and aligned with the workpiece origin
Strict Adherence to Operating Procedures
Operators must be trained and certified before machine operation. During operation:
- Do not modify system parameters without authorization
- Do not arbitrarily adjust tool compensation
- Do not measure, wipe, or replace workpieces while the machine is running
- Do not leave a machine in operation
Maintain a suitable machining environment
Keep workshop temperatures stable to prevent thermal deformation caused by temperature fluctuations
Maintain a clean work area to prevent metal chips from accumulating on guideways and lead screws
Use coolant appropriately during machining to reduce temperatures and extend tool life
Prohibit placing vibration sources or strong magnetic field equipment near the machine to avoid compromising machining accuracy
Standardize Tool and Workpiece Usage
Use tools compliant with machine specifications; over-specification installation is prohibited.
Ensure tools are mounted steadily and securely fastened, with minimal protrusion.
Workpieces must be clamped symmetrically to prevent vibration caused by eccentricity.
Select appropriate cutting parameters when machining different materials.
Safety Precautions
Do not reach near rotating spindles.
Avoid wearing scarves, gloves, or other items that may become entangled in the machine.
Ensure emergency stop buttons are accessible and familiarize yourself with their operation.
When shutting down, first return to zero, then stop the spindle, and finally disconnect the power supply.
II. Common Improper Operations and Their Consequences
| Common Improper Operation | Consequence |
| Failing to check the coordinate origin before operation | Program offset, tool collision, or spindle damage |
| Running the program without a dry run test | Program errors causing machine crash or tool breakage |
| Using worn-out or unqualified cutting tools | Poor surface finish, spindle overload, servo motor overcurrent |
| Excessive tool overhang | Tool vibration, reduced machining accuracy, possible tool breakage |
| Insufficient or incorrect coolant use | Accelerated tool wear, workpiece burning, spindle overheating |
| Unauthorized modification of system parameters | Control system malfunction or unexpected machine movement |
| Failure to clean chips in time | Guide rail blockage, leadscrew scratches, coolant system clogging |
| Improper shutdown procedures | Forgetting to return to zero, turning off power before spindle stops, damaging drive system |
| Overloading the machine for long periods | Motor overheating, premature spindle bearing failure, increased backlash in leadscrew |
III. Correct Practices for Extending the Service Life of CNC Lathes
Establish a Daily Maintenance Routine
Machine tool maintenance is categorized into daily, weekly, monthly, and annual checks:
- Daily Maintenance: Clean metal chips, inspect lubricant levels, verify coolant circulation
- Weekly Maintenance: Check turret positioning accuracy, clean electrical cabinet filters
- Monthly Maintenance: Verify guideway oil flow integrity, adjust belt tension
- Annual Maintenance: Inspect spindle clearance, ball screw nut wear, and servo system precision
Maintain Optimal Lubrication Conditions
Lubrication is critical for extending machine tool lifespan. Regularly verify lubrication system functionality. Critical components like guideways, ball screws, and turrets must never run dry or use mixed lubricants.
Avoid prolonged overload operation
Allocate production tasks reasonably to prevent extended full-load or continuous high-intensity operation. Schedule machining intervals when necessary to allow sufficient cooling time for the spindle and servo system.
Electrical and Environmental Protection
- Regularly inspect electrical cabinet temperature and fans
- Ensure proper grounding
- Avoid excessive humidity
- Prohibit unauthorized power connections
- Perform maintenance and cleaning only after power is disconnected
Enhance Operator Training
Equipment lifespan depends on user proficiency. Companies should regularly conduct training on operational skills, safety knowledge, and maintenance to familiarize operators with machine performance, proper function usage, and anomaly detection.
Establish Machine Operation Records
Document and analyze machine runtime, maintenance logs, fault incidents, and tool change frequency. This enables predictive analysis of equipment wear patterns for proactive maintenance.
