Function overview
The bidirectional CNC pipe bending machine produced by King-Mazon introduced in this technology is a kind of automatic pipe bending machine, with left bending and right bending bidirectional pipe bending function. The bidirectional pipe bending machine is designed with two layers of molds, one of which has the function of large radius push bending. The CNC pipe bending machine is obviously superior to other CNC pipe bending machines in bending thick wall pipes and bending high strength pipes. The equipment can be used to bend round pipe, square pipe, rectangular pipe, oval pipe and other profiles with high precision and fast, which can meet the bending processing requirements of various three-dimensional pipe fittings. It is also one of the advanced equipment with flange high precision bending in the world.
Meet the following requirements
For 300MW, 600MW, 1000MW boiler water wall φ31.8 ~ φ114 pipe cold bending.

FAQ
Q1: What is a left and right CNC tube bending machine?
A: A left and right CNC tube bending machine is a bidirectional bending system that can bend tubes both clockwise and counterclockwise within the same cycle, without releasing or repositioning the workpiece. This allows complex, multi-plane tube geometries to be formed continuously with high accuracy and repeatability.
Q2: What are the main advantages of bidirectional bending compared to unidirectional machines?
A: Bidirectional bending eliminates manual flipping and re-clamping, which reduces handling time, labor cost, and tolerance stack-up errors. It also protects the tube surface and pre-installed components, making it ideal for complex parts such as automotive fluid lines and HVAC coils.
Q3: What types of tubes and materials can it handle?
A: The machine is suitable for both metal tubes and pipes, including carbon steel, stainless steel, aluminum, copper, and thin-wall materials. It supports various diameters and wall thicknesses, depending on machine configuration and tooling. Custom tooling can be provided for special tube profiles.
Q4: Can it handle pre-flanged or pre-formed tubes?
A: Yes. With dynamic head shifting and specialized tooling, the machine can avoid collisions with pre-installed flanges, end fittings, or other components. This reduces the need for secondary welding or post-bend assembly operations.
Q5: What should buyers check before ordering?
A: Buyers should confirm tube diameter, wall thickness, material, required bend radii, number of bends per part, and the minimum straight length between bends. It is also important to verify tooling compatibility, control system functions, and after-sales support, including training and spare parts availability.
