技术介绍
机械加工是指通过一种机械设备对工件的外形尺寸或性能进行改变的过程,按加工方式上的差别可分为切削加工和压力加工。加工需要的机械由数显铣床、数显成型磨床、数显车床、电火花机、万能磨床、加工中心、钻床、激光焊接、快走丝、中走丝、慢走丝、外圆磨床、内圆磨床、精密车床等。切削加工是指用切削工具(包括刀具、磨具和磨料)把坯料或工件上多余的材料层切去成为切屑,使工件获得规定的几何形状、尺寸和表面质量的加工方法。切削加工一般可分为:车削、铣削、钻削、镗削、铰削、刨削、插削、拉削、锯切、磨削、研磨、珩磨、超精加工、抛光、齿轮加工、蜗轮加工、螺纹加工、超精密加工、钳工和刮削等。钻孔加工是一种常见的加工方式,钻孔是指用钻头在实体材料上加工出孔的操作。盘状工件是具有腔体的圆盘,广泛使用于汽车领域,在盘状工件上钻孔也是一种常见的加工方式,在加工过程中需要实现对盘状工件的定位和夹紧,目前常见的普通夹紧装置不适合盘状工件的定位和夹紧。
