CNC Press Brake and Shearing Machine

CNC Press Brake and Shearing Machine is CNC (Computer Numerical Control) controlled mechanical processing machine mainly utilised for sheet metal bending and forming. CNC press brakes are integrated with a computer numerical control system with hydraulic press brakes with an electrical system.

Latest technology as well as customer needs require that fabrication should be done quicker, and create precise parts. CNC Press Brakes are an important fabrication machine used for bending and forming sheet metal essential in almost every fabrication shop. However, today's CNC technology provides us the CNC control to increase precision sheet metal bending and fast production capacity.  CNC Press Brakes form predetermined bends by clamping the workpiece between a matching punch and die and through force gaged in tonnage bends the metals.

These tonnage and length aspects are vital because every press brake has a concentrated load limit which is calculated in tons per inch, in the center of the press. Using the incorrect tonnage can impair the press ram, the die or the working part which in the worst case could damage the machine beyond repair.

The section molds have diverse shapes and the bending angles can be set in advance. Thus, diverse shapes and angles of metal sheets can be produced massively. First, the CNC press brake takes the sheet metal section flat blank at a distance given by the programmable backstop, the point where the bend will be formed. The distance that the programmable V blade that enters into the V block will be defining the angle obtained of the final bend, the further the V blade enters the V block the tighter the final V bend will be.

The final section is a combination of several bend lengths and angles which are generated by the CNC program that positions the sheet metal component blank at defined positions and at programmed angles. The length of the CNC press brake bed outlines the maximum length of sheet metal section that can be bent up. The greater the opening in the bottom V block, the larger the sheet metal gauge that can be bent for the same tonnage.

• Programmable so it makes switching to different bends, parts and even materials much faster.
• Can bend sheet metal work from a few inches across to sections many feet long. 
• Can check for errors and calculate the correct bend sequence.
• Repeat the motion over and over again for production. 
• Setup time is much faster as the controller calculates all the positions of the ram and back gage.
• CNC press brakes and shearing machines are more specialized than press brakes.

CNC Press Brake and Shearing Machines are extensively utilised in transportation, agricultural machinery, energy, automobile, machinery, shipbuilding, metallurgy, aviation, military, petroleum machinery, power generation industries.
