中心钻的铲磨加工,是工具制造工艺中的薄弱一环。一般是在机床上手动操作,生产效率低,劳动强度大,而且产品质量不易保证,废次品率较离。汤溪工具厂设计制造的这两种中心钻自动铲磨床,可实现全自动化加工,机床结构紧凑合理,加工出的中心钻质量稳定。经该厂多年使用,效果良好。现介绍如下,供其他工具厂和有关工具专用磨床设计单位参考。 Center drill shovel grinding, tool manufacturing process is a weak link. Generally manual operation on the machine, low productivity, labor-intensive, and product quality is not easy to guarantee, waste defective rate away from. Tangxi Tools Factory design and manufacture of these two centers drill automatic shovel grinding machine, can be fully automated machining, compact and reasonable machine structure, the quality of the central processing of the quality and stability. After years of use of the plant, the effect is good. Now introduced as follows, for other tools factory and tool-specific grinder design unit for reference.
