R、B、Tool 公司发展了一种小型精密镗杆新系列—UJ 系列,这种新镗杆的特点是,镗杆上镶有硬质合金不重磨式刀片,并作有一条螺旋槽,加工时可自动清除切屑,此外,安装刀片的螺钉是埋头的,以保证形成一条排屑槽,从而消除了在一般镗杆上的切属堵塞现象;另一个特点是,这种镗杆可用于切削铁素金属和非铁素金属,有左旋和右旋两种,可用于盲孔修底和凸台加工;加工通孔时带有导角,经过精磨的带正前角的刀片,可保证精镗质量,整根镗杆包括断屑槽均进行磨削,也有不带断屑槽的镗杆结构.这种新镗杆的柄部尺寸有:5/16″,3/″,1/2″,5/8″,和3/4″。
R, B, Tool company has developed a new series of small precision boring bar-UJ series, the new boring bar is characterized by boring bar mounted carbide non-resharpening blade, and made of a spiral groove, In addition, chip-mounted screws are countersunk to ensure that a chip flute is formed, eliminating the need for blockage on a typical boring bar. Another feature is that this boring bar can be used to Cutting ferritic and non-ferrous metals, both left and right-handed, can be used for blind hole repair and boss processing; processing through-hole with guide angle, after grinding with a positive angle of the blade can be The quality of the fine boring machine, the entire boring bar including the chip breaker, and the boring bar structure without the chip breaker are available. The shank dimensions of this new boring bar are: 5/16 “, 3/1”, 1 / 2 “, 5/8”, and 3/4 ".
