How to judge the quality of automatic locking screw machine and screw
Views:2138 Date:2020-04-30
For the detection of the hardness of the surface of the screw, this test can be said to be an important characteristic of the screw. For this inspection, if the screw does not require heat treatment, it can be directly tested, but if the screw needs to be hardened, then for The hardness of the screw can be checked after hardening. The inspection of screw appearance is generally divided into three parts.

First of all, whether the appearance of a screw is normal, whether the nut is tilted, the thread of the screw thread, whether it has passed the check rule, etc., such inspection also has defective screws that can exist and defective screws that cannot exist, etc., It is very important to check the appearance. If the appearance of the screw does not meet the requirements of the customer, then this screw is an unqualified screw.

How to check whether the surface of the screw meets the surface of the screw. For the inspection after screw plating, for this kind of inspection, only the screws with electroplating are required. After electroplating, the main check is whether the plating layer has a surface covering the screws, and the uniformity of the plating layer. It can well protect the screw itself and so on.

In fact, many good-quality screws are not single-handedly manufactured, but the screws are inspected in various aspects, and the quality is improved by inspection.

The rapid development of the industry requires continuous support from science and technology.The application range of automatic lock screw machines is very wide.Mobile phones, notebooks, digital cameras, remote controls, computers, toys, clocks, meters, appliances, automobiles, and other production fields Therefore, only by improving the quality of automatic locking screw machines and screws can we win in the future industry competition.
