What is a slitting machine? Longitudinal cutting machine, also known as longitudinal cutting unit or longitudinal cutting line, is a necessary equipment for precision cutting of metal strips in the transformer, motor industry, and other industries. It cuts metal coils into strips of various widths required, and then harvests the strips into small rolls for use in the next process. It is mainly used for cutting materials such as tinplate, galvanized iron, silicon steel sheets, cold-rolled steel strips, stainless steel strips, aluminum strips, steel strips, etc. There are many types of longitudinal cutting lines, which can be divided into thin plate longitudinal cutting lines and thick plate longitudinal cutting lines according to the thickness of the board that can be longitudinally cut; According to the longitudinal cutting metal material, it can be divided into stainless steel longitudinal cutting wire, copper strip longitudinal cutting wire, cold plate longitudinal cutting wire, silicon steel longitudinal cutting wire, etc. According to the degree of automation, it can be divided into fully automatic longitudinal cutting line and semi-automatic longitudinal cutting line. In the pipe making machine, customers need to use longitudinal cutting lines to obtain the size they need, and then produce the pipe material of the required size through the pipe forming machine. The main process of the longitudinal cutting line is: coil storage → winding → unwinding → guiding head → clamping and rough straightening → cutting head → waste collection → nesting → centering → longitudinal cutting → waste edge winding → nesting → separation and tension → slitting → separation and winding → unloading. The CNC metal coil longitudinal cutting line produced by Jinan Zeye Machine Tool has won the national "utility model patent certificate" and is popular both domestically and internationally; Zeye Machine Tool is trustworthy!
