CNC Press Brakes Main Components: Bed, Ram, Punch and Die, Back Gauge, Frame
It runs vertically along the Y axis and is positioned by numerical control at specific positions according to the operation to be performed. There are independent Y1 and Y2 axes that regulate the possible unbalance of the machine’s main ram (in a hydraulic press these are the different strokes that the cylinders can perform).
The CNC system manages the vertical movement of the ram and the horizontal positioning of the back gauge. Additionally, some press brakes feature a crowning system that adjusts the bed's curvature to ensure uniform bending.
Ram: The ram applies force to the metal sheet, creating the bend.
Back gauge: The back gauge positions the sheet metal accurately before bending.
Crowning: This optional feature helps prevent uneven bending by adjusting the bed's shape.
X: "Forward and backward", sets the length of the bend (flange) from the centre of the die to the tip of the fingers.
R: "up and down", adjusts the height of the stops/fingers to allow the fingers to reach the part better and so that dies of different heights can be mounted.
Z: "left and right", adjusts the position of the stop/s on the table, to ensure that the back fingers are in the correct support position towards the punch and die.

🛠️ What is a CNC Press Brake Machine?
A CNC Press Brake Machine is a computer-controlled machine tool used for bending sheet and plate metal. It is widely used in fabrication shops, automotive, aerospace, and heavy machinery industries for precise, repeatable metal forming.
🔹 Key Components:
Ram/Punch: The top tool that presses down.
Die: The bottom tool against which the metal is pressed.
Back Gauge: Adjusts the position of the metal sheet.
CNC Controller: Automates movement and settings (angle, stroke, pressure).
Hydraulic or Electric System: Provides the power for bending.
🔧 How It Works:
The metal sheet is placed on the die.
The CNC controller positions the back gauge.
The ram lowers to bend the sheet to a specified angle.
Multiple bends can be done in sequence automatically.
✅ Advantages:
High accuracy and repeatability
Suitable for complex multi-step bends
Reduces manual labour
Allows automatic tool changes in advanced models
Can handle a wide range of material types and thicknesses
🔍 Common Applications:
Control panels
Brackets and enclosures
Automotive body panels
Elevator parts
Kitchen equipment
Furniture frames
