What Should A Dedicated Person Be Responsible For When Operating A Double-column CNC Vertical Lathe?

When operating a double-column CNC vertical lathe, the core goal of assigning dedicated personnel is to ensure equipment safety, machining accuracy, and production efficiency, while also reducing the risk of failure and maintenance costs.

◆Safety Protection Implementation

Guardian Inspection: Before starting the CNC lathe, a designated person must verify that safety devices such as the grating guard door, emergency stop button, and limit switches are functioning properly to prevent casualties from CNC lathe equipment failures (e.g., accidentally opening a guard door while the spindle is rotating).
Hazardous Area Control: Operators must be supervised to stay away from hazardous areas such as the rotating spindle and tool changing area of ​​the CNC lathe, and unauthorized personnel are prohibited from entering the machine's working area.

◆Operational Procedure Compliance
Standardized Operation: A designated person must strictly follow the CNC lathe operating manual provided by the supplier to prevent misoperation that could cause the CNC lathe to crash or overtravel.
Exception Handling: In the event of an emergency such as a broken CNC tool or loose workpiece, a designated person must immediately press the emergency stop button and report it to prevent the accident from escalating.

◆Workpiece Clamping and Tool Setting
Precision clamping: A dedicated person must select appropriate CNC lathe fixtures based on the workpiece material and shape, and align them using a micrometer to ensure concentricity ≤ 0.01mm.
Tool Setting Accuracy: The CNC lathe uses trial cutting or a laser tool setter to input tool compensation parameters (such as X/Z axis tool wear values) to ensure that the first-part machined dimensions meet tolerance requirements (e.g., ±0.02mm).

 

◆Program Optimization and Parameter Adjustment
Program Verification: A dedicated person must simulate the program using the CNC machine's lock function to check whether the tool path interferes with the workpiece or fixture to avoid batch scrapping.
Dynamic Parameter Adjustment: The CNC lathe adjusts the spindle speed and back-cut depth based on material hardness and cutting force.
Quality Traceability: A dedicated person must record the machining parameters (such as cutting speed and tool life) for each batch of CNC lathe workpieces to provide data support for process improvements.

◆Daily Maintenance Execution
Cleaning and Lubrication: A dedicated person should clean scrap metal daily, especially from the guideway gaps on dual-column CNC vertical lathes, clean the lead screws and scales, and apply lubricant to reduce wear and corrosion.
Fluid Level Check: Confirm that the lubricant and coolant levels on CNC vertical lathes are within normal ranges to prevent overheating or workpiece burns caused by insufficient fluid.

Fault Prediction and Treatment

Abnormal Monitoring: A dedicated person should observe the CNC vertical lathe's spindle status, including abnormal noise, vibration, and oil line leaks, to identify any abnormalities. This allows for early detection of issues such as spindle bearing wear or excessive lead screw play on dual-column CNC vertical lathes.
Quick Response: In the event of an electrical fault (such as a control system freeze), a dedicated person should restart the CNC vertical lathe according to procedures or contact maintenance personnel to minimize downtime.

◆Operation Log Completion
Processing Records: A dedicated person is required to record the number of workpieces processed on the CNC lathe during each shift, tool change times, and reasons for equipment downtime (e.g., tool changes, malfunctions), providing a basis for production scheduling.
Quality Reports: Statistics are compiled on the pass rate and scrap rate (e.g., scrap due to dimensional deviations or surface defects) of CNC vertical lathe workpieces, and the root causes of any problems (e.g., program errors or unstable clamping) are analyzed.

◆Operator Training
Theoretical Training: A dedicated person is required to explain to new operators the operation of CNC vertical lathe systems (e.g., FANUC, SIEMENS), G-code programming, and the basics of mechanical drawing.
Practical Guidance: Operators must complete at least 50 hours of on-the-job training on a CNC vertical lathe under the supervision of a skilled operator and pass a simulated machining test (e.g., turning a stepped shaft) before being able to perform independent operations.
Regular Refresher Training: Participate in CNC lathe safety regulations and new technology training every six months to enhance their skills.
