Appendix A
(Appendix of the standard)
Method for testing the dynamic and static balance of diamond rollersA1.1 Instrument: BIWy-100B flash dynamic balancing machine or a dynamic balancing machine of equivalent performance. A1.2 Technical requirements for mandrels used for balance testingA1.2.1 The coaxiality of the taper journal of the journal, belt shaft, and sleeve wheel shall be less than or equal to 0.005mm. A1.2.2 The hardness shall not be less than 50HRC, and the surface roughness Ra value shall not be greater than 0.40 um. A1.2.3 The end face of the shaft head at the sleeve wheel position shall be marked with average fractions of 1, 2, 3, and 4 to determine the unbalanced phase. A1.2.4 The total weight of the mandrel and roller shall be greater than the lower limit of the weight that can be measured by the balancing machine. A1.3 Prepare according to the requirements of BLWy-100B dynamic balancing machine: A1.3.1 Equipment speed: 2400r/min.
A1.3.2 Place the balancing mandrel on the V-groove, put on the transmission belt, and adjust the vertical tension strength to make the mandrel rotate stably. A1.3.3 Adjust each knob to the following positions: a) "Left measurement" and "right measurement" rotation refers to the \10\ position; b) "Left" and "right" rotation refers to the \5" position; c) "Left", "static" and "right" rotation refers to the "static" position; d) "Light" and "heavy" rotation refers to the "heavy" position (select according to weight removal). A1.3.4 The relative position of the roller and the mandrel should remain unchanged before and after weight removal, and should be measured twice from the relative position of 180° A1.3.5 Power on and preheat for 1 to 2 minutes.
A2 Operation||tt| |a) Start the motor first;
b) Adjust the "input attenuation" switch to gear 1. If the meter exceeds the full scale, it can be attenuated in the order of "3", "10", "30" and "100" so that the pointer is between "0" and the full scale;
c) Adjust the "frequency adjustment" button so that the pointer reaches the maximum value; d) Turn on the "flashlight" and move closer to the roller, observe the horizontal position number, and record the position and meter reading; e) Stop the machine and remove the roller for weight removal until the attenuation gear number and meter reading corresponding to the standard value are reached. A3 Determination of attenuation gear number and electric attenuation reading
A3.1 When inspecting a batch of rollers of the same specification for the first time, the first roller should be balanced to the best accuracy of the machine, that is, when illuminated by a flashlight, the handwriting is unclear and the meter reading is the smallest.
The residual unbalance value of this roller can be measured according to the "Method for measuring the accuracy of the workpiece" in the manual. If the center of gravity offset of the residual unbalance value is less than or equal to 0.001mm, the highest accuracy of the machine has been achieved. Then calculate the weighted mass corresponding to the standard push value according to formula (A1). G

The center of gravity offset specified by the standard, mm. For example, for a diamond roller, the center of gravity offset e(standard) = 0.063mm; the radius of the weighted position, mm.
According to the specifications of the roller, weigh the plasticine according to the calculated weight and adhere it to the selected weighted radius; then inspect it according to the above method. At this time, the weighted object should be clearly visible in the horizontal position when illuminated by the flashlight. Note the number of attenuation gears and the meter reading. This number is the gear number and meter reading corresponding to the allowable standard value.
When inspecting the roller, if the gear number and meter reading are less than the gear number and meter reading, it means that the center of gravity deviation does not exceed the standard allowable value, and the roller is qualified without deweighting; if it is greater than the gear number and meter reading, it can be deweighted to make it less than the value, which means it is qualified. A3.2 If the flash position is shifted after deweighting in the first inspection, it means that the weight and position of the deweighting are not accurate. It is allowed to deweight at the new position, but the drilling deweighting shall not exceed three places at most. In order to make the deweighting position accurate, it is necessary to correctly adjust the "frequency adjustment" knob and strive to accurately determine the flash horizontal position. 2681When inspecting a batch of rollers of the same specification for the first time, the first roller should be balanced to the best accuracy of the machine, that is, when illuminated by a flashlight, the writing is unclear and the meter reading is the smallest.
