Product description

the impact sample notch broaching machine is the only device that can process the notch of the qualified Charpy impact sample except for the optical curve grinder in the country. the machine adopts the processing principle of one-time forming, and the machined notch has excellent uniformity. this equipment is a necessary special equipment for metallurgy, boiler pressure vessels, vehicles, engineering machinery manufacturing and scientific research institutions and other departments.

Working principle

the broaching machine adopts gear rack transmission, and manually rotates the handwheel to rise and fall the broach, thereby broaching the notch. this product is equipped with one broach, optional broach model: V type (deep 2mm) or U type (deep 2mm), you can also buy two broaches, tool change is simple and quick, no complicated steps, operation reliable. The broach of the broaching machine is made of W18Cr4V material with high hardness and good wear resistance. Each cutter can process more than 20,000 samples.
