刀具特点:刀具结构如图1~图4所示,由刀体、刀片、前、后锁紧螺母等组成。刀体上开有八个等分槽,刀片安装后,锁紧前后螺母,经刃磨即可使用。刀槽底具有4°30′斜角,当刀刃磨损使镗孔尺寸变小时,可使刀片向后移动一定距离,将刀刃的外径增大。一般调整到有0.5毫米刃磨量即可,然后,锁紧螺母,再经刃磨便可继续使用。采用45钢做刀片,在其上焊有硬质合金刀头。
Tool Features: Tool structure shown in Figure 1 to Figure 4, from the blade body, blade, before and after the lock nut composition. There are eight slots on the knife body, after the blade is installed, the nut is locked before and after the grinding can be used. The bottom of the flute has a 4 ° 30 ’bevel, which allows the blade to move backwards a certain distance as the cutting edge wears down to make the outer diameter of the blade larger. Generally adjusted to have a 0.5 mm grinding amount can be, then, lock nut, then by grinding can continue to use. Made of 45 steel blades, welded carbide tips.
