我厂目前正在使用一种不用抬刀装置的硬质合金刨刀;现把这种刨刀介绍出来,供大家参考。 1刨刀的几何形状及特点(如附图):前角Y=11°20';主后角a=3°10';刀刃斜角=12°50';付后角a_1=4°;刀尖角=90°。在切削刃上磨有负倒棱f=0.5。特点: 1)刨刀有较大前角,所以切削比较容易,切屑变形较小。2)后角α较小,所以切刀后隙面的支撑面积较大,因而减少了震动。此外,当后角减小
I plant is currently using a no lift knives carbide carpenter Planer; now this Planer introduced, for your reference. 1 planer geometry and characteristics (as the figure): rake Y = 11 ° 20 ’; the main relief angle a = 3 ° 10’; rake angle = 12 ° 50 ’; after the pay angle a_1 = 4 °; knife Sharp angle = 90 °. In the cutting edge grinding negative chamfer f = 0.5. Features: 1) Planer has a larger rake angle, so cutting is easier, less deformation of the chip. 2) The clearance angle α is smaller, so the support area of the cutter clearance is larger, thus reducing the vibration. In addition, the relief angle decreases
