说明:1.刀具特点:本刀具采用10°前角和较大的容屑槽,便于切屑顺利排出,并留有30毫米长的校准部分,可经多次修磨刀具寿命较长,于切削一次成形,保证了产品另件的几何形状和精度要求。2.切削用量:n=165转/分;S=工件螺距;V=15米/分。3.使用效果:由于本刀具采用一次拉削成形,工效与原来车削相比,车削工时8分钟,拉削工时定额是2分3秒,实际为1分30秒,提
Description: 1. Tool Features: The tool with a 10 ° rake and larger chip flute, easy chip excretion, and leave a 30 mm long calibration section can be multiple grinding longer tool life, cutting A forming, to ensure that the other parts of the product geometry and accuracy requirements. 2. Cutting capacity: n = 165 rev / min; S = workpiece pitch; V = 15 m / min. 3. The use of results: As a result of the tool forming a broach, work efficiency compared with the original turning, turning hours 8 minutes, broaching hours quota is 2 minutes 3 seconds, the actual 1 minute 30 seconds to mention
