CSL-B-3 Impact Specimen Gap(three knives)Power-driven Broaching Machine

1. Equipment name and Model

CSL-B-3 Impact Specimen Gap Electrical Broaching Machine (Three Knives)

2. Usage and characteristics

Impact Sample Gap Broaching Machine is the only instrument for processing the qualified charpy impact sample gap, except the optical curve grinding machine. Because of once processing theory, the gap identity is very nice.

2.1.This machine adopts high-precision ball screw drive, linear guide and support, this structure ensures the broach stability and geometric precision of gap.

2.2. This product is equipped with three broaches, which can process three gaps simultaneously: three V-notch or U-notch, or choose according to needs. Processing one sample gap only need 10 seconds, it is easy to operate and reliable for processing the V-and U-gap.

2.3. It can meet GB/T 2106-80 “Metal Charpy (V type notch) impact test method” and GB/T 229-2007 “Metal Charpy (U-type notch) impact test method”, as well as the corresponding request of ASTM E23, ISO148, ISO0083 standards at home and abroad.    

2.4.The broaching machine adopts W18Cr4V manufacturing, high hardness, good wear resistance, each broach can process the samples as many as 20,000.

2.5. It is necessary and special equipment of metallurgy, pressure vessel,vehicles and vessels, construction machinery manufacture industries and departments of science and research.
