304 hard medical grade stainless steel capillary tube precision cutting chamfering polishing mirror processing

Mirror polishing process Mirror polishing directly depends on the level of finish, which is directly interpreted as being as smooth as a mirror. The polishing process of inferior stainless steel can be divided into two parts: grinding and polishing. The two-part process and method are now summarized as follows
ⅠGrinding
The main goal of grinding stainless steel welded parts is to remove the solder joints and achieve a surface roughness of workpiece to prepare for light emission!
In summary, the grinding part includes
three processes: rough grinding, semi-fine grinding and fine grinding
three surfaces, two sides and one edge
nine polishing machines
Twenty-seven adjustment mechanisms,
Detailed descriptions are as follows
Conduct visual inspection of the workpieces transferred to the polishing process in the previous stage, such as whether there are leaks in the welds, welding penetration, and uneven depth of the welding spots. Too far away from the seams, local dents, uneven docking, deep scratches, bruises, severe deformation and other defects that cannot be remedied in this process. If there are any of the above defects, they should be returned to the previous process for repair. If there are no defects mentioned above, proceed to this polishing process.
Rough grinding, using an abrasive belt to grind the workpiece back and forth on three sides. The goal of this process is to remove the solder joints left by the welding of the workpiece, as well as the bruises that occurred in the previous process, to achieve the welding joint circle. The corner is initially formed, and there are basically no large scratches or bumps on the horizontal and vertical surfaces. After this step, the surface roughness of the workpiece should be able to reach pressure on the work piece. Generally speaking, it is more appropriate to be in a straight line with the thrown surface!
Semi-finish grinding, the abrasive belt used is to grind the three sides of the workpiece according to the previous method of grinding the workpiece back and forth, mainly to correct the joints that appeared in the previous process and to further refine the impressions produced after rough grinding. Grinding, the marks left by the previous process must be repeatedly ground until the surface of the workpiece has no scratches and is basically bright. The surface roughness of this process should be up to (be careful not to produce new scratches and bumps in this process, because such defects cannot be repaired in subsequent processes.)
, fine grinding, the abrasive belt used is mainly for the front To correct the fine lines that appear in the first step, the grinding method is the same as above. The goal to be achieved by this process is that the joint between the grinding part and the unground part of the workpiece will basically disappear, and the surface of the workpiece will be further brightened. The workpiece after grinding through this process will basically have a mirror effect, and the surface roughness of the workpiece should be able to reach
Ⅱ. Light emitting part
The main purpose of the light emitting part is to mirror the polished stainless steel to achieve the purpose of mirror surface. Generally speaking, this process has two processes: waxing and polishing
Two motors, two wool wheels, large green wax, cloth
The specific content is as follows
Visual inspection For the welded parts that entered this process from the previous step, check to see if there are any missing grinding spots, incomplete grinding of all solder joints, rough grinding marks, serious damage to the protective film, excessive grinding, excessive filleting, or serious grinding at both ends. , Uneven polishing, and uneven depth in some places. Problems that occur during various polishing and polishing stages that cannot be repaired during the polishing stage. If such problems exist, you need to return to re-polishing or repairing. (Bumps, scratches, and large scratches that occur during polishing cannot be repaired in this process, but very small fine lines, such as relatively small fine lines caused by polishing, can be repaired. But it is very troublesome)
Mirror surface
Use a high-speed motor driven wool wheel (available on the market) and use daqingwax to mirror-polished the workpiece following the previous polishing method. The main purpose of this process is to mirror-polished the workpiece that has been polished in the previous steps. Polish instead of further grinding. Be careful not to rub the polishing wax onto the covering film on the surface of the workpiece during this step, and be careful not to damage the covering film.
Polishing
This process is mirror polishing In the last process, use a clean cotton cloth wheel to rub the mirrored workpiece surface, wipe clean and polish the workpiece after all previous processes have been completed. The goal of this process is that no welding traces can be distinguished on the surface of the workpiece, and the waxed and polished workpiece will be removed. The polished workpiece has a brightness as high as mirror reflection, and there is almost no difference between the polished and unpolished parts of the workpiece. A complete mirror effect is achieved.
A few additional points about polishing
Polishing method
The polishing method is basically the same as the waxing method, except that the wool wheel is rotated during waxing.
Polishing is the last process in the entire polishing process, and it must be ensured that the workpiece is polished to shine There will be no damage to the mirror surface in the end, otherwise all the previous efforts will be wasted.
The brightening method is to install the cloth wheel directly on the high-speed motor to achieve high-speed rotation, wipe it on the surface of the workpiece, and wipe off the dirt and adhesion on the workpiece. Daqing wax, to achieve the purpose of polishing! In actual polishing, abrasive powder is often used together. The abrasive powder can remove the oily substance Daqing wax. Its main function in polishing is to make it easy to polish. Remove the green wax adhering to the workpiece. If you do not use abrasive powder, the large green wax on the surface of the workpiece will be difficult to remove, and it will easily stick to other places, affecting the beauty of other places.
The brightness meets the mirror requirements, and the clean condition of the cloth wheel is particularly important. In actual production, the cloth wheel needs to be replaced in time depending on the specific situation.
