Application of laser cutting machine in medical equipment industry
Due to the special use environment of medical devices, we have relatively high requirements for their precision, safety, finish, sanitary conditions, etc. Therefore, when manufacturing medical devices, we must strictly require manufacturers from the source . In the process of metal medical equipment processing, the traditional sheet metal mechanical cutting processing mode has great defects in terms of accuracy, safety, and controllability. Therefore, the replacement of traditional processing methods by fiber laser cutting machines is an inevitable trend in the development of the industry.
First of all, laser cutting meets the precision, safety, and finish requirements of the medical profession. Fiber laser cutting is to use a high-power density laser beam to scan the surface of the material to heat the material to thousands to tens of thousands of degrees Celsius in a very short time to melt or vaporize the material, and then use high-pressure gas to cut the melted or vaporized material from the material. Blow away in the seam to achieve the purpose of cutting the material. This extremely high-temperature cutting ensures that the equipment will not be contaminated twice during the processing of the equipment. The cut surface finish of the processed material is very good, which can meet the requirements of one-time molding, and avoid the secondary or multiple reprocessing after the material is formed. Time and material loss.
Secondly, in terms of the workpiece itself, medical devices are quite different from other mechanical parts. It requires very high accuracy without any deviation, and the laser cutting machine can meet these processing requirements well when performing equipment processing and cutting.
In addition, the slit produced by laser cutting is very narrow, the laser beam is focused into a small spot, so that the focal point reaches a high power density, the material is quickly heated to the degree of vaporization, and evaporates to form holes. With the relative linear movement of the light beam and the material, the hole continuously forms a slit with a very narrow width. The slit width is generally 0.10-0.20mm. The extremely small cutting seam ensures the high precision of cutting.
The production and processing process of the laser cutting machine is a non-contact processing, the laser cutting head will not contact the surface of the processed material, and the workpiece will not be scratched. For medical devices, the surface is the most basic requirement. If the surface polishing process of the device products can be minimized during the processing, the production efficiency will be greatly improved.
