Introduction
The tube endforming machine is one of the most important pieces of equipment in the modern metalworking industry. Essential for shaping the ends of metal tubes, this technology allows the creation of complex, high-precision components used in sectors such as automotive, aerospace, furniture, HVAC, marine, and agriculture.
At VLB Group, the EF Series Tube Endforming Machine represents the pinnacle of engineering applied to bending. Designed to ensure speed, power, and consistency, it combines state-of-the-art electric and hybrid systems with intuitive, programmable software.
This article will explain everything you need to know about: operation, applications, benefits, technical specifications, and much more.
What is a Tube Endforming Machine?
A tube endforming machine is an industrial equipment that shapes the ends of tubes, altering their shape and diameter to allow for specific fittings, joints, enlargements, reductions, or finishes.
Unlike bending machines, the forming machine acts on the ends, allowing the tube to take on complex shapes, such as:
- Conical
- Cylindrical
- Threaded
- Beveled
- Precise couplings

How a Tube Endforming Machine Works
The operation is based on three main steps:
- Tube clamping – the tube is firmly clamped by high-strength clamps
- Tool movement – specific tools shape the tube through controlled and sequential pressure.
- CNC programming – the operator sets the deformation parameters on a touch screen, ensuring precision and repeatability.
