Performance characteristics
The broach is made of W18Cr4V tool alloy material, the tool parameter design is reasonable, and the service life is high;
The hydraulic components are all well-known brands to ensure the reliability and stability of the hydraulic system; it is equipped with a lubrication system to supply oil to the broach blade and the broach guide device, so as to cool, lubricate and clean the broach, so that the broached broach can be cleaned. The notch and surface roughness of the sample are guaranteed, and the service life of the broach is extended;
The frame frame part is welded by angle steel, channel steel and other profiles. The structure design is reasonable and conforms to the operator's habits. The panel and other parts are sheet metal structures, which are easy to disassemble and assemble. The surface is sprayed with plastic, and the appearance is neat and beautiful;
