在切削过程中,由于机械摩擦和热效应等作用,刀具会产生磨损,这种磨损少则使刀具的几何形状受到改变,大则使刀具刃口烧坏,甚至崩落。磨损到一定程度必须及时重磨,否则将影响工件尺寸的精度和表面光洁度,导致产品质量降低,甚至报废。而对于尚能切削的力具若磨刀过于频繁,又使机床 In the cutting process, due to mechanical friction and thermal effects such as the role of the tool will produce wear and tear, the less the wear and tear of the geometry of the tool is subject to change, big knife blade is burned out, or even collapse. Wear to a certain extent must be regrouped in time, otherwise it will affect the accuracy of workpiece size and surface finish, resulting in reduced product quality, or even scrapped. And yet to cut the power if the sharpener is too frequent, but also to machine tools
