Application advantages of CNC plate drilling in chemical industry-6
- 11 August 2020
SUPERNOVA CNC plate drilling machine has subverted the traditional processing mode for hole processing in chemical industry. It is now the main CNC drilling machine for processing chemical flange, heat exchanger, tubesheet, etc. Before using the traditional hole processing method, first fitter scribed positioning, and then fixed the well positioned tubesheet on the bench vice, and then drilled with a radial drilling machine. For large hole diameter, even through two procedures of drilling and reaming. Compared with the traditional hole processing method, the advantages of NC plate drilling machine are as follows:
（6） Measurement of repeated indexing accuracy of rotary table
The measurement method is to repeat positioning three times at any three positions within one week of the rotary table, and detect them under the rotation in the positive and negative directions respectively. The maximum indexing accuracy of the difference between all reading values and the theoretical value of the corresponding position. If it is a CNC rotary table, take one measuring point every 30 as the target position, and conduct five times rapid positioning for each target position from the positive and negative directions respectively, and measure the difference between the actual position and the target position, that is, the position deviation. Then calculate the standard deviation according to the method specified in gb10931-89. Six times of the maximum standard deviation of each measuring point is the CNC return The accuracy of repeated indexing of rotary table. Welcome your consult to know more:Kevin
