不同刃磨方式下带锯锯齿表面质量的分析研究

STUDY ON SURFACE QUALITY OF BANDSAW′S TOOTH WITH DIFFERENT GRINDING METHODS

本文就刃磨方式对带锯锯齿表面质量的影响进行了分析研究。结果表明：带锯经传统的非冷却式横磨法刃磨后，锯齿表面质量差，锯割时易于磨损和开裂。采用新型的冷却式纵磨法，可以改善磨削条件，提高锯齿的疲劳强度和耐磨性，有效地防止疲劳裂纹的产生与扩散。

This paper is focused on the studying of influence on the surface quality of bandsaw′s tooth with the grinding method.The result shows that the conventional uncooling horizontal grinding method makes the surface quality of bandsaw′s tooth low,on the contrary,the new cooling vertical grinding method can improve grinding condition,heighten fatigue strength and wearingresisting capacity,and it can eliminate fatigue cracks efficiently.
