A Turning is to use a lathe to remove some materials from the blankor semi-finished products to form themA kind of machining process, whichwastes raw materials and has low processing efficiency, thus resultinginThe cost and price are falsely high. Cold upsettingis the process ofupsettingand forming the blank by means of air hammer and other equipmentlt is apressure processing process of. lt can compress the crystal of the blankmore closely through the impact forceDense, so that the product has higherstrength and toughness, high processing efficiency and appearanceBeautifuwithout car marks. Compared with turning, cold heading has lower price andbetter quality!
