我厂在龙门刨床上成批加工底座的T型槽或宽槽时,由于槽的宽度尺寸均有严格的公差要求,所以我们应用了刀头可调的硬质合金宽度割刀。使用效果十分理想,大大提高了零件的加工质量和效率。可调式宽度割刀结构见附图:它由锥度为1∶50小端带M6螺纹的锥销1、头部两侧焊有硬质合金,并在中间钻锥孔和开3mm小槽的刀体2、锥销拉紧螺帽3等组成。使用时,根据图纸上槽的公差要求,将锥销螺帽3缓缓旋紧,由于锥销上锥度作用,刀宽H尺寸慢慢胀开,从而使刀宽H取得了所需的精确的尺寸公差。这种可调式宽度割刀,其可调节胀开范围在1mm左右,可调尺寸精度<0.02mm。由于割刀调节方便,加工出工件精度高,故具有相当普遍的实用性。我厂
Our factory in the gantry planer batch processing of the base of the T-slot or wide slot, the width of the slot due to the size of the strict tolerance requirements, so we use the adjustable carbide tip width cutter. The use of the effect is very satisfactory, greatly improving the quality of parts and processing efficiency. Adjustable width knife structure shown in the attached figure: It consists of taper 1:50 small end M6 thread taper pin 1, both sides of the head welded carbide, and in the middle of the drill hole and drill 3mm small slot knife Body 2, taper pin tightening nut 3 and other components. Use, according to the drawings on the groove tolerance requirements, the tapered nut 3 slowly tighten the taper pin taper effect, the knife width H size slowly open, so that the knife width H to obtain the required precision Size tolerances. This adjustable width knife, which can adjust the expansion in the range of about 1mm, adjustable size accuracy <0.02mm. Due to the cutting knife adjustment convenience, the workpiece precision machining, it has a very common practicability. my factory
