In the world of tube bending, there are a ton of options, features, controls, and concepts that can overwhelm a prospective buyer. Many of these options can be removed or narrowed down by discussing the type of bender you need:
semi-automatic or CNC?
At Tube & Pipe Bending Machines, we work with all shapes, sizes, options, and brands of tube benders. Below is a brief overview of semi-automatic versus CNC tube benders that can help you determine which option makes the most sense for your specific needs.
Semi-automatic tube bender (also known as the NC series) is a basic machine that performs a sequenced set of steps to bend a part using an NC control unit interface. In basic terms, the steps go like this:
The machine can have a limit switch to set the degree of bend or an encoder attached to a programmable control to set the degree of bend. However, a semi-automatic tube bender will NOT reposition the tube between bends. In order to automatically produce a tube with numerous bends with limited operator involvement between each bend, you may need a CNC tube bending machine.
CNC tube bender (CNC – Computer Numerical Control) performs the same functions as a semi-automatic tube bender but with less operator involvement thanks to the use of multi-axis computer-controlled servos. A CNC tube bender automatically positions the tube between bends, including the rotation of the tube (B-Axis) and the distance between bends (Y-Axis). Both measurements are critical and can be difficult to control with a NC tube bender.
Once the machine positions the tube in place, it goes through the same clamping, bending, and releasing steps as the semi-automatic machine. But instead of the operator repositioning the tube manually, the machine uses the carriage to hold and move the tube to the next position before making the next bend.
Now that you know the differences between a semi-automatic and a CNC machine, you still need to determine which one to buy from: Tube & Pipe Bending Machines. To make this decision, it is important to consider four main factors:
To discuss your specific project needs and to make an educated decision that will yield the best results.
