Application of various cemented carbide milling cutters

The selection of mold milling cutters?
The reasonable lifespan of mold milling cutters Surface Milling Inserts is generally divided into high productivity mold milling cutter lifespan and low-cost mold milling cutter lifespan. The former is determined based on the goal of fewer working hours per piece, while the latter is determined based on the goal of lower process costs.
Compared with ordinary machine tool processing methods, CNC machining puts forward higher requirements for mold milling cutters. It not only requires good rigidity and high precision, but also requires dimensional stability, long service life of mold milling cutters, and easy installation and adjustment to meet the requirements of CNC machine tools. High efficiency requirements. The die milling cutter selected on CNC machine tools usually uses die milling cutter materials suitable for high-speed cutting, and uses indexable inserts. For multi tool and combination machine tungsten carbide inserts tools with complex tool installation, tool replacement, and tool adjustment, higher life standards for mold milling cutters should be selected, while ensuring the reliability of mold milling cutters. When the productivity of a certain process in the workshop limits the improvement of the overall workshop productivity, or when the overall factory cost allocated per unit time for a certain process is large, a lower method should also be chosen for the lifespan of the mold milling cutter.
When determining the lifespan of mold milling cutters, factors such as mold milling cutter manufacturing, grinding costs, and complexity can be considered. For indexable tools with short tool change times, in order to improve production efficiency and fully utilize their cutting performance, a lower life of the die milling cutter can be chosen. The lifespan of complex and high-precision mold milling cutters should be higher than that of single edge milling cutters. In the precision machining of large parts, in order to ensure that the tool is completed at least once and avoid changing the tool midway during the cutting process, the lifespan of the mold milling cutter should be determined based on the accuracy and surface roughness of the part.
