1.Overview
This machine is an auxiliary specialized equipment of the metal pendulum impact testing machine, which produces metal impact specimens with different notch shapes according to corresponding standards. This machine adopts hydraulic transmission and electric control (using solenoid valves to control the lifting and lowering of the cutting tool), with controllable speed adjustment (the speed control valve can adjust different cutting speeds). At the same time, lubricating oil is used to cool and lubricate the cutting tool, ensuring that the prepared sample gap size and surface quality meet the requirements. The blade is made of high-quality alloy material, which has a long service life. The equipment is stable and reliable, easy to operate, and has high sample preparation efficiency, making it the best supporting equipment for metal impact testing machines.
