Information

Some tips for medical sheet metal processing:

1. In order to prevent debris damage, the transparent baffle should be installed in the appropriate position.

2. When the surface of the workpiece needs to be polished with gauze, the tool should be moved to a safe place, taking care not to let hands and clothes touch the surface of the workpiece. When polishing the inner hole, do not use fingers to hold the gauze, use a stick instead. At the same time, not too fast.

3. Do not place tools, fixtures or workpieces on lathes and spindle gearboxes. Concentrate on your thoughts while you work. No fatigue, chatting, multi-person operation, drinking and smoking.

4. Keep machine tools, tools and working environment clean and handover. When cleaning, the staff should cut off the power supply and put all kinds of material rods in a safe position.

5. When turning irregular workpieces, a counterweight should be installed and then cut.

6. The tool clamping should be firm, and the protruding part of the cutter should not exceed 1.5 times the height of the cutter body. The shape and size of the bottom gasket of the precision stainless steel sheet metal processing knife should conform to the shape and size of the knife body, and the gasket should be as little and flat as possible.

7. In addition to the automatic measuring tools installed on the lathe, the tool holder should be moved to a safe position before measuring the workpiece.

8. The saw blade and long spiral chips generated in the cutting process should be removed with the hook in time, and it is strictly prohibited to pull by hand.

9. Wear work clothes, tight cuffs and protective glasses before going to work. Female employees should wear hats. Hair caps are issued on a permanent basis. No gloves allowed.

10. The chuck should be loaded and unloaded on the spindle of the lathe, and it should be stopped to be taken out by the power of the motor.

11. The protruding part of the fixture, dial and chicken core clip should be protected to avoid strangling clothes and other parts of the body when the sheet metal of the distribution cabinet is processed. If there is no shield, keep some distance.

12. When using the fixture workpiece, it should be noted that the center and the center hole of the spindle should be completely consistent, and the damaged or twisted can not be used. The top and middle holes should be cleaned before use, and the top of the tail seat should be firm.

13. When turning slender workpieces, in order to ensure operation safety and processing quality, the tool holder or intermediate frame should be used. Removable protective covers and safety signs should be provided outside the machined parts of the machine.

How to improve the customization accuracy of medical sheet metal processing?

Errors are inevitable in the processing of medical sheet metal. To ensure efficiency, reduce material waste and labor, it is necessary to ensure and improve processing accuracy. So, what methods can improve the processing accuracy?

Original error reduction method: If there are errors in production, first find out the main factors affecting the processing error, and then try to eliminate or reduce these factors. For example, the processing of parts with shaped surfaces is mainly to reduce the shape error of the forming tool and the installation error of the tool.

Original error compensation method: Artificially create a new error to offset the original error in the process system. When the original error is negative, the human error is positive, otherwise it is negative, trying to make the two dimensions equal. The original error transfer method: the original error of the machining system is transferred to the direction that the machining error is not sensitive or other aspects that do not affect the machining accuracy under certain conditions. For example, when the accuracy of the machine tool can not meet the requirements of parts processing, conditions can be created on the processing or fixture, so that the geometric error of the machine tool is transferred to the aspect that does not affect the precision sheet metal processing accuracy of the chassis.

Original error equalization method: If the positioning error is large, the difference method can be used. That is, the original error is divided into n groups according to its size, and the error range of each group is reduced to the original 1/n, and then adjusted according to each group.

Original error homogenization method: For parts with high machining accuracy, homogenization method can be used. It identifies differences by comparing closely related surfaces and then modifies or benchmarks each other, thereby reducing and equalizing errors on workpiece surfaces. In machining, machining accuracy error is inevitable.

Only by analyzing the factors affecting the error, can corresponding preventive measures be taken to reduce the processing error of high-precision plate and improve the processing efficiency.
