半圆刀的设计与应用

针对一些特殊材料如酚醛层压布板、有机玻璃、硬聚氯乙烯、超硬铝等孔的精加工、台阶孔的加工以及金属材料孔的半精加工,设计了一种半圆刀.使用半圆刀可达到孔的加工精度和表面粗糙度要求.半圆刀的制造与使用并不复杂,企业一旦掌握半圆刀的制造,孔的半精加工、精加工将不再受普通铰刀尺寸规格的限制,有助于提高特殊材料加工精度,这对企业工...

Design and Application of Semi-circular Knife

A kind of semi-circular knife has been designed for finish machining some special materials just like phenolic cloth laminated panels, plexiglass, PVC, super-duralumin finishing hole. This kind of semi-circular knife also can be used to machine the stepped hole and semi-finish metallic material hole. The machining accuracy and surface roughness of holes can be achieved by the semi-circular knife. The manufacture and application of the semi-circular knife is easy, the semi-finish and finish machining will not be limited by the standard of general reamer once companies master the manufacturing methods. It will improve the accuracy of machining special materials and be good to the tool manufacture.
