                    Analysis of blade types of slitting machine

                    Flat knife cutting machine blade, Yellowstone cutting machine blade use design for flat knife form, such a design cut out the quality of the plate is very good, will not appear distortion phenomenon, and in use because the upper and lower two surfaces are parallel design, so when in use can be divided into cutting type and cutting type, This requires the operator to have the necessary operating experience in the operation, to avoid the occurrence of unexpected situations in the work, causing damage to the equipment or the loss of the price of the plate.

                    Roll selection

                    The commonly used roll materials and uses are shown in the table. The performance and quality of a roll generally depend on its chemical composition and method of manufacture and can be assessed by its organizational

                    Classification of rolls

                    Stainless steel roll products are mainly composed of roll body, roll neck and shaft head 3 parts. The roll body is the middle part of the roll that is actually involved in rolling metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing and the rolling force is transmitted to the frame through the bearing seat and the holding down device. The shaft head of the driving end is connected with the gear seat through the connecting shaft, which transmits the torque of the motor to the roll. Rolls can be arranged in the mill frame in the form of two, three, four or multiple rolls.

                    Performance characteristics of slitting blades

                    Standardized production process and strict quality control perfectly combined casting stable product quality, free from your worries. Acid and alkali resistance, corrosion resistance, oxidation resistance, no rust characteristics. The blade of the slitting machine has high hardness, sharp edge and good wear resistance, and the working cycle of the cutting machine is long. The tungsten steel slitting machine blade with coating follow-up treatment is more convenient to use.

                    Performance characteristics of slitting blades

                    The blade of the longitudinal shear machine uses a high-precision grinder to fine grind the edge, with high processing precision and high finish to achieve the mirror effect (Ra≥0.012). The edge is sharp, no breaking edge, no rolling edge phenomenon. The section of the cut needle is smooth, smooth, no hairless puncture, no barb phenomenon. Select 0.6um subfine crystalline hard alloy powder after precision molding by high temperature and low pressure sintering, the product internal microstructure is good, effectively reduce the micro pores in the alloy, improve the density, avoid the edge in the fine grinding and use of the phenomenon of edge breakage, improve the finish of the cutting section.

                    Machining requirements for steel rolling blades

                    The diversity of rolling blade and the characteristics of working state determine the difference in the selection of cutting tool coating. Different from drilling and turning, milling cutter should consider the characteristics of intermittent impact. The early development of coating to wear resistance as the main focus, to improve the hardness as the main index. Such coatings represented by titanium nitride have a high friction coefficient (0.4 ~ 0.6), and the continuous friction between the workpiece and the processing will generate a lot of heat energy. Cutting fluid is usually used to avoid overheat deformation affecting machining accuracy and prolong its service life.
