A Study of spiral tap with Large Diameter

厦门大学学报（自然科学版） 2002年第S1期41卷 134-135页

作者： LI Lin 1, LI Da-wei 1, CHAI De-ming 2 (1. Tianjin Chinese-German Vocational Training Center, Tianjin 300191 , China 2. The Experimental Eanipent-Making Factory under Physical Chemistry Academy spiral, Tianjin 300180, China)

The design and manufacture of spiral tap yet are in r esearch stage at present. This paper mainly introduces how to calculate its geom etric parameters and scientific selection of them with vector method. In additio n, an empiric formula of the tool life of spiral tap with large diameter is esta blished by method of correlation. The practice of design, manufacture and applying proves the advantage of spiral tap by the comparison between the spiral tap and common tap with same size. In the application of spiral tap has got better economic effect. The cutting fea ture and economic effect are obvious, that mean spiral tap greatly better than c ommon tap. The bright and wide prospect are going to come. No greatly increasing the ω can be effective to improve the cutting condition. Scientific selection of cutting speed V can increase the tool life of tapping and life of tapping too l.
