Do you want to know the accurate charges when the engineer repairs your machine? this is a reference for you, so, you can bargain with engineer and pay the less money.There are too parts for press brake,so,we only take several examples.The grind of press brake die is about USD 100,including upper mold and bottom mold.Of course,the grind need professional knowledge and skill.please try your best to do, if not, please find somebody to help you.As long as you do this,it can succeed.

  Another way to count charges is according to the time.for example,the engineer cost half a day to maintain your machine,you should pay at least their salary.then,you should note which parts they changed and ask them to give you a look at broken parts.when you did this action,the engineer generally dare not cheat you because he also worry you to report him to his boss.these things are due to personal engineer.the boss must have no interest to do this,they do not need so little money but concern more about their brand of press brake.
