Selection of bending machine

In the purchase of bending machine, once the wrong choice, production costs will rise, bending machine can not expect to recover costs. Therefore, several factors need to be considered in decision-making.

Workpiece: the first important thing to consider is the parts you want to produce. The key point is to buy a machine that can complete the processing task with the shortest worktable and the smallest tonnage. Carefully consider the material grade and the maximum machining thickness and length.

Deflection: you should also consider the possible deflection of this machine. Under the same load, the deflection of the table and slide block of the 10 foot machine is 4 times that of the 5-foot machine. This means that shorter machines require less shimming to produce qualified parts. The reduction of gasket adjustment shortens the preparation time.

Bending radius of parts: then, we must focus on the bending radius of parts. When free bending is adopted, the bending radius is 0.156 times of the die opening distance. In the process of free bending, the die opening distance should be 8 times of the metal thickness.

Degree: bending accuracy requirement is a factor that needs to be carefully considered. It is this factor that determines whether you need to consider a CNC bending machine or a manual bending machine.

Molds: even if you have molds full of shelves, don't think they are suitable for new machines. Each die must be checked for wear by measuring the length from the front end of the punch to the shoulder and between the shoulder of the female die.

Side length of bending parts: one factor that people often ignore is the bending side length of materials before the bending machine.
