毛主席说:“古代战争,用矛用盾:矛是进攻的,为了消灭敌人;盾是防御的,为了保存自己。直到今天的武器,还是这二者的继续。”金属切削刀具是切削加工的武器,它的刃口首先要有“矛”的进攻能力:硬、耐磨耐热、锋利,以便顺利切入工件。其次,它还要具有“盾”的防御能力,以保证在高效率的前提下具有合理的耐用度。

Chairman Mao said: “In ancient times, the use of spears and shields: the spear is offensive, in order to destroy the enemy; the shield is defensive, in order to save themselves. Until today’s weapons, or both continue.” Metal cutting tools are cutting Weapon, its edge must first have a “spear” offensive ability: hard, wear heat, sharp, in order to successfully cut into the workpiece. Second, it also has the “shield” defense capability to ensure reasonable durability with high efficiency.
