Importance of determining the machining allowance of bending machines

When using the sheet metal bending machine, in addition to operating the equipment according to the correct operating method, it is also necessary to pay attention to the measurement of the processing allowance. The processing allowance is related to the use of the equipment. Too large or too small processing allowance will have a certain impact on the use of the equipment. Therefore, targeted calculation and determination of the processing allowance can greatly improve the efficiency of the equipment. Let's analyze the importance of determining the processing allowance.
If the finishing allowance selected by the press brake is too large, it will increase the cutting force, thereby affecting the processing accuracy and the surface quality of the workpiece. On the contrary, if the finishing allowance is too small, the error left by the workpiece in the previous processing procedure cannot be eliminated, and surface defects, process clamping errors, etc. will increase the workpiece to become waste. Therefore, the finishing allowance should be reasonably determined according to the factors affecting the size of the processing allowance.
The finishing allowance of the press brake should be determined by analytical calculation. The various factors affecting the finishing allowance need to be comprehensively analyzed and calculated using calculation formulas and certain test materials to determine its finishing allowance. The finishing allowance determined by this method is more economical and reasonable, but there must be relatively complete and reliable test data.
When using a press brake to operate materials, you are required to master the machine parameters proficiently. During the setting process, you should pay attention to setting the processing allowance parameters of the equipment, and then process the materials according to the requirements. This can ensure that the allowance parameters during the processing meet the requirements, which can not only improve the working efficiency of the equipment, but also extend the service life of the machine.
