Metal-ceramic saw blade is also called cold saw. It is a special tool for cutting steel. It has the characteristics of fast speed, high accuracy,and long life. It is a new cutting tool in recent years. The efficiency is about ten times that of ordinary saw blades. About five times thatwhen sawing small-diameter materials, there are unparalleled advantages of saw blades, ironworking cold sawing. The cold saw is welded bythe blade body and the cutter head, and the stress is eliminated through a special process, so that the saw blade is not deformed during thehigh-speed and high-intensity sawing process. Because the precision of the cold saw is very high through the processing of precisionequipment, the cutting surface is very smooth, and the precision is high, which can save the margin reserved for subsequent processing andreduce material loss.
