此拉床专门针对于冷凝器铜阀座平面加工,在加工精度、效率要求高的情况下特别能显示其优越性,三工位专用设计, 一次拉削3个工件,具有结构简单,操作、维修方便等优点,并可配置自动上下料,节约人工成本,,除此之外,对冷凝管主阀座的加工,其检测的标准是泄露量,故对平面度的要求及拉刀的精度都要求非常高。特别对于小孔径的拉刀,如何保证刀具的精度等非常关键。

该机床主要技术参数为:
拉力: 50KN
行程:800mm
切削速度: 1.5-9m/min
表面粗糙度: Ra 1.6
生产节拍: 25秒/ 2件
Broaching machine for surface of main valve of condensing tube One of features of refrigerating industry is large-scale production. It has strict demands on stability. Besides, it has high demand on flatness and precision of broach and the test standard for main valve base of condensing tube is leakage .The key is to ensure precision of tools for small bore broach. We pay great attention on reliability and size tolerance of this machine when working.
At meantime, we are working with users to improve the technique. Owing to efforts we paid, the machine works well and it becomes a good machine.
Main specification:
Pulling capacity: 50kN
Stroke: 800mm
Cutting speed: 1.5-9m/min
Surface roughness: Ra 1.6
Producing efficiency: 25sec/2 pieces
