When choosing the bending machine improperly, the production cost will rise, and the bending machine can not expect to recover the cost. Therefore, there are several factors that need to be weighed in decision-making:
1. Workpiece: the first important thing to consider is the parts you want to produce. The main point is to buy a machine with the shortest workbench and the smallest tonnage that can complete the processing task. Carefully consider the material brand and the maximum machining thickness and length.
2. Deflection: you should also consider the possible deflection of this machine. Under the same load, the deflection of the worktable and slide of the 10 foot machine is 4 times that of the 5 foot machine. That is to say, shorter machines need less gasket adjustment to produce qualified parts. Reducing gasket adjustment also shortens preparation time.
3.Bending radius of the part: next, the bending radius of the part must be considered. When free bending is adopted, the bending radius is 0.156 times of the opening distance of the die. In the free bending process, the opening distance of the die should be 8 times of the thickness of the metal material.
4. Degree: the bending accuracy requirement is a factor to be considered carefully. 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 full shelves of molds, don't think these molds are suitable for new machines. The wear of each die must be checked by measuring the length from the front end of the punch to the shoulder and the length between the shoulder of the die.
5. Side length of bending parts: one factor that people often neglect is the side length of bending materials in front of the bending machine.
