THE WORLD'S TOP BEARING MANFACTURER ,JANPAN'S NSK GROUP IN CHINA PURCHASES SINOWON SU-300M

2021-07-21





                                                    Test samples and requirements:

Measured workpiece: Bearing (Figure one)

Product dimension: 1~49mm(internal diameter)

Product material: ISO683-17

Hardness requirement: 60~65HRC

Measurement requirements: Fully check the hardness of the bearing

Instrument used: Motorized ultrasonic hardness tester SU-300M

The company is the world's top bearing manufacturer, Japan's NSK Group, in Shenyang, China. It mainly produces high-quality bearings and guide rails. Figure 2, Bearing manufactured from the company.

Hardness is one of the important indicators of the quality of bearings and guide rails. 

As the world's top bearing manufacturer, its control of bearing hardness is very strict. The choice of hardness tester directly affects the quality of bearings and other products.

Sinowon SU-300M Motorized Ultrasonic Hardness Tester has won their love and high praise.

What's

need



1. The customer needs a hardness testing solution with precision, fast-speed and NDT . It is known that Rockwell hardness tester has a large indentation, and the measured product cannot be used after the testing. It is not suitable for mass nondestructive measurement or full inspection.

2. Vickers hardness tester need operators with experienced skills and low efficiency, and it is not suitable for customers to test large quantities of products.

3. Portable Leeb hardness tester is not suitable for such small parts due to the diameter is too small to test.







       


Our Solution



According to the current pain points of measurement, we decided to use an ultrasonic hardness tester to measure the sample.

Sinowon Ultrasonic Hardness Tester SU-300M adopts 3N test force, which can fully inspect the hardness of the motor shaft without damaging the workpiece, effectively guaranteeing the production quality of the product.

    



Test conclusion

 

    

 SU-300M is able to measure the hardness of hardness of small cylindrical workpieces with precision, fast-speed and NDT solution.

 SU-300M ultrasonic hardness tester has simple operation and high reliability. It only needs to prepare a standard sample to calibrate the   instrument, which can achieve accurate hardness         measurement.

 While using the ultrasonic hardness tester to improve the quality control of the enterprise, it also reduces the loss and increases the profit of the enterprise.
