brake Machine accuracy and mold
Precision required is a careful consideration of the factors, it is this factor, the decision you need to consider a CNC Bending Machine Bending Machine or hand-controlled. press brake If the bending precision 1 but should not change, you must focus on the CNC machine.
CNC Bending Machine slider Repeatability is 0.0004 inch, forming a precise angle to be used such precision and good mold. Manual bending machine slider repeat accuracy of 0.002 inches, and in the use of a press brake suitable mold under conditions in general will produce 2 ~ 3 deviation. In addition, CNC bending machine for rapid loading mode to prepare, when you need to bend the system in many low-volume parts, this is considered an unquestionable reason.
Mold
For the conventional mold, each foot deviation should be about 0.001 inch, and the deviation of the total length of not more than 0.005 inch. As for grinding mold, each foot should be the accuracy of 0.0004 inch, press brake the overall accuracy of not more than 0.002 inch. Better to die for grinding CNC bending machine, the conventional mold for manual brake Machine.
