This broaching machine is specially used for machining the plane of copper valve seats of condensers, and can particularly exhibit its superiority when the machining accuracy and efficiency are highly required. Special design of three stations enables the broaching machine to broach 3 workpieces at a time with the characteristics of simple structure and convenient operation and maintenance, etc., and automatic loading and unloading devices can be equipped so as to save the labor cost.

      Besides, for machining of main valve seats of condenser tubes, the standard of detection is leakage rate, so both the planeness and accuracy of broaches are very highly required. Especially for broaches at small bore diameter, how to guarantee the accuracy of cutting tools is critical.

Main technical parameters of the broaching machine are as follows:

Tensile force:50KN

Travel:800mm

Cutting speed:1.5-9m/min

Surface roughness:Ral.6

Production takt time:25 s/3 workpieces
