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.
