Important precautions for operating CNC machine tools (vertical machining centers)
In modern manufacturing, CNC machine tools (vertical machining centers) play a crucial role. In order to ensure the safety and effectiveness of operation, the following is a detailed explanation of the four major precautions for operating CNC machine tools.
1、 Basic precautions for safe operation
When entering the workshop for an internship, dressing is crucial. Make sure to wear work clothes, tie the big cuffs tightly, and tie the shirt inside the pants. Female students are required to wear safety helmets and have their hair braids tucked into their hats. Avoid wearing clothing that is not suitable for the workshop environment, such as sandals, slippers, high heels, vests, skirts, etc. Special attention should be paid to not wearing gloves to operate the machine tool.
At the same time, be careful not to move or damage the warning signs installed on the machine tool. Sufficient workspace should be maintained around the machine tool to avoid placing obstacles.
When multiple people work together to complete a task, mutual coordination and consistency are crucial. Unauthorized or illegal operations are not allowed, otherwise you will face consequences such as zero score and corresponding compensation liability.
Compressed air cleaning of machine tools, electrical cabinets, and NC units is strictly prohibited.
2、 Preparation before work
Before operating a CNC machine tool (vertical machining center), it is necessary to be familiar with its general performance, structure, transmission principle, and control program. Only by thoroughly understanding the functions and operating procedures of each operation button and indicator light can the operation and adjustment of the machine tool be carried out.
Before starting the machine tool, it is necessary to carefully check whether the electrical control system of the machine tool is normal, whether the lubrication system is smooth, and whether the oil quality is good. Confirm whether the positions of each operating handle are correct, and whether the workpiece, fixture, and tool are firmly clamped. After checking if the coolant is sufficient, you can first idle the car for 3-5 minutes and check if all transmission components are working properly.
After ensuring that the program debugging is completed, the operation can only be carried out step by step with the consent of the instructor. Skipping steps is strictly prohibited, otherwise it will be considered a violation of regulations.
Before machining parts, it is necessary to strictly check whether the machine tool origin and tool data are normal, and conduct a simulation run without cutting trajectory.
3、 Safety precautions during the operation of CNC machine tools (vertical machining centers)
The protective door must be closed during processing, and it is strictly prohibited to put your head or hands inside the protective door. Operators are not allowed to leave the machine tool without authorization during the processing, and should maintain a high level of concentration and closely observe the operation status of the machine tool.
It is strictly prohibited to open the CNC system control cabinet without authorization.
Operators are not allowed to change the internal parameters of the machine tool at will, and interns are not allowed to call or modify programs that are not created by themselves.
The machine tool control microcomputer can only perform program operations, transmission, and program copying, and other unrelated operations are strictly prohibited.
Except for the installation of fixtures and workpieces, it is strictly prohibited to stack any tools, clamps, blades, measuring tools, workpieces, and other debris on the machine tool.
Do not touch the tip of the knife or iron filings with your hands. Use an iron hook or brush to clean them.
Do not touch the rotating spindle, workpiece, or other moving parts with your hands or other means.
It is prohibited to measure workpieces or manually change gears during the processing, and it is also not allowed to wipe workpieces or clean machine tools with cotton thread.
Attempting operations are prohibited.
When moving the positions of each axis, it is necessary to clearly see the “+” and “-” signs on the X, Y, and Z axes of the machine tool before moving. When moving, slowly turn the handwheel to observe the correct direction of the machine tool movement before accelerating the movement speed.
If it is necessary to pause the measurement of workpiece size during program operation, it must be done only after the standby bed has completely stopped and the spindle has stopped rotating, in order to avoid personal accidents.
4、 Precautions for CNC machine tools (vertical machining centers) after completion of work
After completing the machining task, it is necessary to remove chips and wipe the machine tool to keep it and the environment clean. Each component should be adjusted to its normal position.
Check the condition of lubricating oil and coolant, and add or replace them in a timely manner.
Turn off the power and main power on the machine tool control panel in sequence.
Clean the site and carefully fill out equipment usage records.
In summary, the operation of CNC machine tools (vertical machining centers) requires strict adherence to various precautions. Only in this way can the safety of operation and the quality of processing be ensured. Operators should always remain vigilant and continuously improve their skill level to fully leverage the advantages of CNC machine tools.
