Poor lubrication of the press brake machine hydraulic may lead to sheet cracking
Improve the lubrication premise: the relationship between the forming quality of bending machine and lubricant is very important. Poor lubrication premise or improper selection of lubricant may lead to sheet cracking press brake machine hydraulic. Adjust drawbead parameters or blank holder force: the use of drawbead can prevent flange parts from folding, but its side effect is to increase the activity resistance of the material into the concave die, therefore, improper drawbead parameters may lead to bending machine activity resistance… Read More »Poor lubrication of the press brake machine hydraulic may lead to sheet cracking
