Measurement of Wear Spots in Four Ball Friction and Wear Testing Machine

Four-ball friction and wear testing machine of the grinding spot measurement

The measurement of wear marks is doneFour ball friction and wear testToday, Hengxu editor will introduce to you the relevant knowledge of wear spot measurement, which is the most important part of the process.

The measurement of ground spotis the most important part of the four-ball friction wear test. Today, we will give you some knowledge about the measurement of the ground.

The measurement of steel ball wear marks is carried out using our company's specially developed wear mark measurement system, with a measurement accuracy of0.01mm， Through the special design of the bottom mounting platform, it is possible to measure the wear marks of three steel balls in the oil box without removing the steel balls. When measuring, first place the oil box on the microscope stand, align the steel balls with the objective lens of the microscope, and then rotate the focusing handwheel to obtain clear wear marks. Rotate the oil box and measure the average wear spot diameter of the other two steel balls in sequence using the same scheme. The arithmetic mean of the average wear spot diameter of the three steel balls is the average wear spot diameter of this experiment.

Of ball mill is developed by using our special grinding spot measurement system to complete, the measuring accuracy is 0.01 mm, through special design at the bottom of the mounting plate, can not take out the steel ball, under the condition of three steel ball mill in the oil box of spot measurement, measurement when oil box first placed on a microscope, the steel ball on the microscope objective lens, then turn the focusing handwheel, get clear spots. The rotary oil box is used to measure the average grinding diameter of the other two steel balls in the same scheme. The arithmetic mean of the average diameter of the three steel balls is the average grinding diameter of the experiment

In general, for the same grinding spot, before the PB point, the grinding spot reading data shows that the horizontal direction is greater than or equal to the vertical direction, and after the PB point, the grinding spot reading data shows that the vertical direction is greater than or equal to the horizontal direction, which is normal.

In general, for the same spot, before the point of PB, grinding spot to read the test data, and the horizontal is greater than or equal to the longitudinal direction, after the PB point, grinding spot to read the test data, and vertical is greater than or equal to the horizontal, as normal.

Looking forward to communicating and learning with you!
