本刊1962年第12期刊登的“镗杆机轴向刀架的快速退刀”一文引起我们的兴趣,因为我厂也设计了一台镗杆机(镗杆直径φ240毫米、总长3600毫米)。为了节约一个动力头,把它安放在C666型车床上来带动镗杆旋转,其走刀丝杆传动的型式类似于原图(也可参考本文的附图)。阅读原文后,发现其中的公式2(用于走刀)及公式4(用于退刀)与实际使用情况不符。为了便于对照,现将原式抄录如下:
Our publication No.12, 1962, entitled “Fast Retraction of Axial Tool Holder for Boring Bar,” aroused our interest because our factory also designed a boring bar machine (diameter of boring bar φ240 mm, total length of 3600 mm) . In order to save a power head, put it in the C666 lathe to drive the boring bar rotation, its drive screw drive type similar to the original (also can refer to the drawings). After reading the original, found that the formula 2 (for the knife) and formula 4 (for retraction) and the actual use of discrepancies. In order to facilitate the control, now the original copy as follows:
