Precautions for processing precision hardware parts: 1. Check whether the moving part is filled with lubricating oil before the machine works, then start and check whether the clutch and brake are normal, and turn the machine tool by Air 1-3 minutes, it is strictly prohibited to operate when the machine is faulty.
2. Keep the correct posture at work and have sufficient spirit to cope with the work. If you find any physical discomfort, you should leave your job immediately and report it to the leader.
When operating, one must concentrate one's thoughts. Chatting and cooperating with each other are strictly prohibited. Operators must not operate in a state of irritability and fatigue to avoid accidents and ensure safe operation.
Before entering the job, all employees should check whether their clothes meet the job requirements.
Slippers, high heels and safety-affecting clothing are not allowed. Those with long hair should wear safety helmets.
3. When replacing the mold, the power supply should be turned off first. After the movement Department of the punch stops running, the mold can be installed and debugged.
After installation and adjustment, move the flywheel by hand and try to punch twice. Check whether the upper and lower dies are symmetrical and reasonable, whether the screws are firm, and whether the blank holder is in a reasonable position.
4, must wait for other personnel to leave the mechanical work area, and take away the debris on the workbench, can start the power to start the machine.
5. When working mechanically, it is forbidden to reach into the working area of the slider, and it is forbidden to take and place the workpiece by hand.
Tools that meet the standards must be used when taking and placing workpieces in the die.
If abnormal sound or machine failure is found, the power switch should be turned off immediately for inspection.
After the machine is started, it is transported by one person and operated by the machine. Others are not allowed to press the power construction or step on the pedal switch board, nor can they put their hands into the mechanical working area or touch the moving part of the machine with their hands.
6. When leaving work, turn off the power supply and tidy up the finished products, side materials and sundries on the post to ensure the clean and safe working environment.
Principle of precision precision machining
: the focus of pure basic level consideration is how to reduce errors and improve accuracy, so the basic principle of selecting essential surface is: first, the principle of reference coincidence.
The design benchmark as far as possible should be selected as the positioning benchmark.
Especially in the final completion, to ensure accuracy, more attention should be paid to this principle.
In this way, the reference deviation of position error can be avoided; Second: the principle of benchmark unification.
All kinds of surface treatments of unified positioning datum should be selected to ensure the position accuracy between each surface as much as possible;
Sometimes it also follows the principle of common benchmark and is processed repeatedly; Third: Self-benchmark principle.
Some small precision machining allowance and unified finishing process ensure machining quality and productivity, with precision machined surface itself as a basic level.
Whether it's automation or artificial intelligence, the rapid convergence of technology and business often determines machining parts’s competitiveness.
