6211 Bearing Product Testing:
1.Metallographic structure checking
Bearings steel and ordinary steel, it is a kind of used in the manufacture of ball bearings, roller bearings ring and steel.
Compared with other steel, bearings steel with higher and more uniform hardness and abrasion resistance.
The most rare is that of bearings steel with ultra-high hardness at the same time,have very strong elasticity.The assurance of hardness can prolong the service life of bearings.
2.Diameter checking during grinding production
CNC bearings grinding machine is mainly used for grinding bearings ring inner diameter. CNC bearings grinding machine is a multipurpose manufacturing machine tools.
The whole machine tool grinding cycle are completed automatically.including automatic feeding, automatic finishing grinding wheel, the size of the automatic compensation, automatic control, the operator only needs a manual loading. CNC bearings grinding machine is applicable to both single small batch production, CNC bearings grinding machine is also applicable to a large number of mass production.
3.Groove testing by the Profile instrument
It can measure the various kinds of bearings components of the linear shape,straightness,angle,convexity,logarithmic curve,groove depth,groove width,groove shape,arc and other parameters.
With high frequency rate and high accuracy,it can accurate and fast measure &test for the object contour,two-dimensional size,two-dimensional displacement.
By this way,it can control the accuracy of bearings & bearings components effectively.
4.Dimension testing for goods
In order to ensure the accuracy of the bearing dimension, before the final packing, we will to check the appearance and dimension by our quality inspection person with many years experience ,to ensure qualified goods arrive customer warehouse.
5.Vibration testing
Bearings vibration and noise test,it can monitor the bearings noise,while the external oscilloscope,to monitor the abnormal sound & vibration waveform;
It can show the bearings vibration velocity with low,medium and high frequency RMS (m/s),the vibration detector can effectively reduce the adverse factors in the process of assembling.
In order to control the finished bearings vibration and noise effectively, improve the bearings life.
6.Fatigue life testing
It is use for measuring the bearings defect by high frequency acceleration & vibration measurement,lt can analysis the domain waveform,FFT frequency to analyze the reason part failure,through the detection of the instrument,lt can check out for the bearings fault produced during the first production process,soas to guarantee the bearings long lifetime.
