Polishing process and safe operation rules of polishing machine

Changshu what machinery Co., LTD.

1. Safety check the polishing machine before operation, make the polishing machine idle, check whether the connecting rod of the grinder, linen wheel or cloth wheel is fastened with the motor, and whether the fastener is loose, and do a good job of cleaning, after everything is confirmed to be normal, it is possible to work.

2. Start the polishing motor and install the polishing wheel with the rotation force of the motor shaft. After tightening, apply the polishing wax to the polishing wheel, so that the polishing can start.

3, check product appearance before polishing, polishing process of on the way to visual inspection of the artifacts, such as whether there is leakage welding seam, welding wear, solder joint depth is uneven, deviating from the seam too far, local sag, docking not neat, whether there is a deep scratches, damaged, deformation, etc. In this process will be able to remedy the defects, if has the above defects should return process to finish. If there is no defect above, enter this polishing process.

4, the first is rough polishing, rough polishing is the stainless steel metal bracket surface file marks, clamp marks, burr and welding left by the black oxide layer first off, as far as possible to throw smooth, harmonious, radian smooth, smooth lines. But also can not force too much, polishing too hard, such as in the metal bracket surface left a dent will be difficult to restore its appearance. Rough casting is the basis of fine casting, if not up to the requirements will affect the later polishing, directly affect the quality of the product.

5, polishing is a certain skill, polishing operator's polishing technique will affect the quality of polishing, polishing operation is not correct it is impossible to throw good products. Generally speaking, when polishing, try to make the product parallel to the polishing wheel, hold the product with both hands and move from top to bottom along the wheel direction. If the polishing technique is not correct, the polished product is very easy to be bounced off the high speed flying polishing wheel, to prevent the jump polishing and force weight uneven. If there is a jump, it could be that the polishing wheel is not on the axis, it could be that the polishing wheel is not round, or it could be a gesture problem. Find out the reason and solve the problem.

6, any stainless steel products after rough polishing must be fine, in order to make the surface of stainless steel products more clean, fine polishing is in the rough, in the foundation of further fine polishing, so that the surface of stainless steel products more flat, smooth, achieve the mirror effect. But its polishing friction contact surface is small, when polishing not only the force to be small and force to be uniform. Polished products should have a bright and clean surface like mirror.

7, polishing method and waxing methods are basically the same, only waxing in the wool rotation for the cloth wheel in the polishing. Polishing is the last process in the whole polishing, we must ensure that the workpiece polished light will not have any damage to the mirror, otherwise the previous work wasted.

8, the polishing method is to install the cloth wheel directly on the high-speed motor, achieve high-speed rotation, wipe on the surface of the workpiece, wipe off the dirt and attachment of the big green wax, to achieve the purpose of polishing! Often in actual polished with grinding powder together, grinding powder can remove oily substance big green wax, its role is largely in the polished in order to easily remove adhesion green wax on the artifacts, if you don't cooperate with grinding powder, big green wax on the surface of the workpiece will be difficult to remove, but also easy to stick to other places, affect other parts of the beautiful.

9. In order to obtain the brightness of the workpiece in line with the requirements of the mirror, the clean condition of the cloth wheel is particularly important. In actual production, the cloth wheel should be replaced in time according to the specific situation.

10, in the polishing process also need to control the pressure on the workpiece, too large pressure wool wheel to polish off the protective film area is too large, or even damage the workpiece, destroy the original mirror effect of the workpiece.

11. During the operation, the operator should always check the safety of the polishing machine. Once the grinding wheel, hemp wheel or cloth wheel and the connecting rod of the motor become loose, the operator should stop the work immediately.

12. When replacing the grinding wheel, hemp wheel or cloth wheel, the power should be turned off. After the replacement, the machine should be checked to see if it is running normally and can work only after confirmation of normal operation.

13. If the polishing machine is found to have abnormal phenomena during work, such as the motor running and stopping or running slowly, the power supply should be cut off or the polishing machine should be replaced immediately.

14. After the end of the work, cut off the polishing electromechanical source and clean the work site. After the machine has been in use for a long time, the lubricating oil in the motor bearing should be replaced in time. Changshu what machinery Co., LTD.
