图示带长方形可转位刀片的车刀可供普通车床和立式车床强力粗车之用。它除具有杠销式夹紧结构的优点外,还具有下列特点: 1.刀片槽的三个基面均进行磨削,因而刀片定位精确,使用可靠。2.V形垫蛰铁及刀杆台肩刚性好,受力合理。3.由两个销子定位的淬硬的磨过的刀垫可防止刀杆损坏。4.散热情况好,铜箍8与刀片相接能,把热量引出切削区,V形垫铁与刀杆间亦有铜垫7导热。该车刀与焊接车刀比较,在加工各种钢和铸铁(包括自口铸铁)时,由于能大大提高切削用量,因而生产效率高;
The illustrated turning tool with a rectangular indexable insert can be used with the powerful rough car for both standard lathes and vertical lathes. In addition to the advantages of the pin-type clamping structure, it also has the following features: 1. The three base surfaces of the blade groove are ground so that the blade can be positioned accurately and reliably. 2.V-shaped mat sting iron and arbor shoulder rigidity, force reasonable. 3. A hardened, worn pad positioned by two pins prevents damage to the shank. 4 heat dissipation is good, copper hoop 8 and the blade phase can, the heat leads to the cutting area, V-shaped horn and the knife bar also has a copper pad 7 thermal conductivity. Compared with the welding lathe, the turning tool has high production efficiency because it can greatly increase the cutting amount when processing various types of steel and cast iron (including self-cast iron)
