A metal hinge is a device used to join two or more objects, usually doors, Windows, boxes, cabinets, machines, etc. It consists of two metal pieces nested within each other, one attached to the object, the other can be turned, and the two are connected by a hinge shaft.
Metal hinges are usually made of metals, such as steel, stainless steel, aluminum, etc., to ensure their strength and durability. The hinge is usually attached to the edge or corner of an object so that it can rotate or swing freely while remaining stable.
There are many types and specifications of metal hinges, which are usually selected according to different applications and needs. For example, there are ordinary hinge, clasp hinge, hidden hinge and so on, each type of hinge has its special uses and advantages and disadvantages.
The advantages of metal hinge include its simple structure, easy installation, high reliability, durability, high bearing capacity, is one of the important parts of all kinds of furniture, buildings, vehicles and so on.
Magnetic polishing effect of metal hinge
How many grinding steel needles are needed to use magnetic polishing machine for metal hinge
When using a magnetic polisher to polish a metal hinge, the number of grinding pins required depends on several factors:
Surface state of the metal hinge before polishing: If the surface of the metal hinge has been relatively flat and there are not too many uneven places, the number of grinding steel needles required may be less.
Polishing purpose and requirements: if the surface requirements of the metal hinge are relatively high, more polishing treatment is needed, then the number of grinding steel needles required will increase accordingly.
Models and specifications of magnetic polishing machines: Different models and specifications of magnetic polishing machines can accommodate different number of grinding steel needles, so it will affect the number of grinding steel needles required.
In general, the number of grinding needles needed depends on the situation, but in general, for small metal hinges, the number of grinding needles needed may only be a few dozen to more than a hundred, and for large metal hinges, more grinding needles are needed for processing.
