CNC cutting machine processing material pretreatment steps

Before CNC cutting of metal materials such as steel plates, in order to cooperate with the cutting process to improve the quality and effectiveness of the cutting, the surface of the material needs to be handled. The following small series put forward some practical opinions on this issue:
The practical process of barrel finishing finishing technology is: degreasing treatment → finishing and deburring → sorting → cleaning → drying → anti-rust treatment degreasing treatment: the parts before finishing must be thoroughly deoiled, Ultrasonic cleaning is often the best method. If the oil on the workpiece enters, the cutting force of the grinding block is obviously weakened, the effect of the grinding agent will be reduced, the effect of the smoothing and the efficiency will be reduced, and the surface of the part after finishing will not be bright.
Finishing: Finishing is mainly based on the structural shape, size, and finishing requirements of the finished part, or the selection of the equipment form, equipment specification, process material, and process parameters.
The finishing process includes three aspects: the separation of the grinding block and the workpiece, the cleaning of the grinding block and the workpiece, and the dehydration and rust prevention of the workpiece.
The common methods for separation of grinding blocks and workpieces are: manual screening, mechanical screening, vibration screening, manual electromagnetic separation, and conveyor magnetic separation, which can be selected according to actual conditions. Ultrasonic cleaning is the best method for cleaning blocks and workpieces. Rinse with clean water. Pay special attention to dehydration, drying, and rust prevention.
