汽缸套内孔的加工,目前我国大多由镗孔改为铰孔工艺,所用专用铰刀主要型式有:1.镶齿式2.整体焊死3.较复杂的机夹。上述三种型式铰刀都具有一些缺点,例如镶齿式的主要缺点是:刀体和镶片制造较困难、麻烦,如齿的精度不高易出现松动现象,刀头需先经焊接在镶片上,经过焊接刀头质量明显下降。对于整体焊死的铰刀其缺点也是刀头经焊接性能变
Cylinder liner hole processing, at present, most of our country by the hole to reaming technology, the main types of reamer used are: 1. Indentation 2. The overall welding death 3. More complicated machine folder. The above three types of reamers all have some shortcomings. For example, the main disadvantages of the insert type are that the cutter body and the insert are difficult to manufacture and the trouble is that the accuracy of the teeth is low and the loosening phenomenon is easy. The cutter head needs to be welded On the chip, after welding the quality of the blade decreased significantly. For the overall welded reamer its disadvantage is the blade by the welding performance change
