1. This machine adopts high-precision ball screw driving, straight lining guiding for support; this structure ensures the stability and the geometric precision of incision of the broach. This product is equipped with a duplex-bit broach, can be simultaneously processed two sample gap: a V-type and a U-type (also the two V-or two U-notches). Whether processing V-or U-notched, ATC is not required, the time of processing one sample gap only need 10 seconds, it is easy to operate and reliable, the processing of the V-and U-gap can be separately meet GB2106-80 "metal Charpy (V type notch) impact test method "and GB229-94" metal Charpy (U-type notch) impact test method ", as well as ASTM E23, ISO148, ISO0083 standards at home and abroad, such as the corresponding request. 2. The broach broaching machine adopts W18Cr4V manufacturing, high hardness, good wear resistance; each broach can process thebe of samples as many as 20 000. 3. Technical parameters processing gap: V-type (GB229-94), U-type (GB229-94) sample size: 10 × 10 × 55,7.5 × 7.5 × 55,2.5 × 2.5 × 55 broach itinerary: 350mm Broaching speed: 2.3m/min working motor: 380V 50Hz 0.4Kw the dimension of the external form: 350 × 510 × 1280 equipment weight: 180Kg
