Impact specimen notch broaching machine is the dedicated and affiliated equipment with metallic pendulum impact testing machine. The machine adopts hydraulic drive, electric control the rise and fall of broach, broach lifting speed can be adjusted, adopting the lubricating oil to lubricate blade mouth parts at the same time, to ensure the sample accords with a requirement gap size and surface finish. The machine due to the use of a forming principle, the machining gap is of good identity. Broach manufactured with high-quality high-speed W18Cr4V steel alloy, and its high hardness, good wear resistance, long service life so per knife more than 20000 samples can be processed.

Applicable Standards:
