Mitech MJB-B series semi - automatic impact testing machine ,control the pendulum movement by servo motor,can be for metal, non-metallic and composite materials under dynamic load resistance to the performance test.Its use of classic mechanical dial display,brings stable performance, simple operation, strong structure, simple structure, high efficiency.Widely used in steel, steel pipe and other toughness of ferrous metals and alloys of its anti-pendulum impact performance of the accurate measurement.It is the necessary professional precision testing equipment for improving production efficiency and saving production costs.

It is widely used in the accurate determination of pendulum impact resistance of ferrous metals and alloy materials, such as steel, steel pipe, etc..

The hemispherical punches of the impact testing machine impact and pass through the specimen at a certain speed and measure the energy consumed by the punch to evaluate the impact resistance of the specimen.

l Read the manual carefully before using the instrument. Learn the operation steps and attentions to avoid damage the 

instrument or personal safety accidents caused by improper operation;

l Test machine is a large precision instruments, should pay attention to water, moisture. Exposed workstations, upper and 

lower beam parts and attached parts should be coated with anti-rust oil to prevent rust;

l It is forbidden to put samples before the pendulum hangs.Before placing the sample, make sure that the pendulum is stable 

and the safety pin has been ejected;

l When using, should pay attention to check the jaw support, pendulum hammer, whether reliable fastening, in order to 

prevent the test results inaccurate or accident;

l The pendulum shaft bearings on both ends of the factory has been the use of units without refueling, refueling, such as 

repairing after cleaning with 1-2 drop of sewing machine oil or watch oil, Vaseline or other power bearing grease;

l If at a long time idle, at least once a week to prevent rust;

l After the test, the pendulum should be placed in the vertical position, and the handle push rod is placed in the braking 

position;

l Don’t disassemble the instrument without authorization, maintenance related matters please contact MITECH after-sale 

service department with 4000600280.
