During a recent conversation in a design group meeting, I overheard someone say, “It looks great, let’s bend it up!” Often, issues affecting the manufacturing process arise, requiring the design group to make adjustments to their design.

Laser cutting machine technology is how to deal with the problem of burr, some customers in the use of laser cutting machine processing sheet metal, cutting out the workpiece effect is very not ideal, and the burr is very much, and many customers begin to doubt the quality of laser cutting machine products, it is not. During the cutting process of metal laser cutting machine, because of improper operation and technical problems, the material will not produce burrs.

Press brake toolAbstractA press brake tool for bending a workpiece includes a punch having a punch tip, a press brake die and a die holder fixing the die thereto. The press brake die includes a pair of rotary members and at least one elastic member. The press brake die further defines an elongated l

CNC hydraulic press brake machineGeneral Characteristics. Accurate positioning and repetability performance of synchronized CNC press brakes, achieved by synchronizing the hydraulic cylinders with advanced CN control of proportional valves and use of optic linear scales..
