Why do big round machines always have unexplained vertical bars and oil needles

The surface of a barrel of ordinary material is very rough when viewed under a microscope, like wood cut by a saw. The rough surface increases the friction between the needle and the syringe. During the operation of the machine, the friction increases and the heat is generated, which increases the internal temperature of the syringe. The high temperature causes the needle oil to evaporate rapidly, resulting in insufficient lubrication, which in turn increases the friction and makes it further Vicious circle.

The high temperature causes the needle oil to evaporate rapidly, resulting in insufficient lubrication, which in turn increases the friction and makes it further Vicious circle. Eventually, the needle cylinder and the knitting needle are worn out, the position of the knitting needle is skewed to produce vertical strips, and the friction metal powder mixed needle oil is brought to the yarn by the knitting needle, resulting in oil needles on the cloth surface.
The surface of the easy-cutting alloy steel needle cylinder is smooth and tidy, because a certain number of easy-cutting elements are added to the steel to form an alloy steel that improves the machinability. In this way, a smooth surface after cutting is obtained, and heat treatment is performed after cutting to further increase the hardness of the needle cylinder. To ensure the service life of the syringe and high-quality cloth effect.
Therefore, when purchasing a large circular machine (large diameter circular weft knitting machine), we must see clearly the material and processing technology of the needle cylinder.
