Tube bending tooling for CNC tube bending machines

We supply tube bending tooling and tools for CNC tube bending machines of various manufacturers and producers for professional tube bending and fabrication. We offer solutions to be used in different sectors of industry from furniture and railing till production of high-pressure hydraulic tube lines and thin walled tube lines in aerospace industry.

Our specialization is the tooling and tools for draw tube bending process with the forming of tube radius according to the size of bending die with the use of mandrel tube and pipe bending machinery.

We offer:

• Separate parts or complete sets of tube bending tooling according to the drawings
• Ball-flexible mandrels in steel or aluminum-bronze alloy
• Single-stack (single level) or multi-stack (several levels) of tooling
• Development of tooling sets for left and right bending; 2 headed tube bending machines
• Profile milled tools for bending after tube end-forming or presenting of additional elements like nuts, rings, couplings etc.
• Round tubes; oval tubes; rectangular or square tubes or special profiles
• Short clamps with minimal straight part on tube
• Push-bending tooling with rolls for variable radiuses
• Additional holders and fixators including quick-change elements and eye-bolts for handling
• Use of drawing from our database or your drawings
• Tooling hardening for the long use
• Any difficulty of project

Mandrels and wiper-dies - the most weared elements for tube bending for perfect bending quality. Moreover we can offer mandrels for any tube bending machine without additional necessary drawings - we just need the information about the bending conditions, material and connection.

We offer:

• Solid or ball mandrels based on radius of the bending
• Special mandrels for oval and square tubes
• Mandrels with the special grooves to pass through the welding seam
• Mandrels and wiper-dies in special aluminum-bronze alloy for steel ferrous materials like stainless and mild steel
• Steel mandrels and wiper-dies for soft material like aluminum or copper
• Replaceable elements for mandrels and connection links and balls
• Wiper-dies according to the customer's drawings
• Any difficulty of bending with the use mandrels with small pitch or additional balls
• Possibilities to make the mandrels for small tubes like 8-9 mm and bigger
• Configuration according to request

Together with our standard tooling quotations, we are ready to verify the complete project for the part to be bent. We provide recommendations regarding the tooling to use, suitable radii, the feasibility of the planned tube geometry (not all models or machines can accommodate every design), implementation using different bending radii on different tooling levels or positioning on the left or right side, and bending frequency.
If the customer works with 3D CAD programs, we can first provide the main CAD dimensions for the tooling after the order is placed, so these can be imported into the software to simulate the tube-bending process in a digital environment.
Various bending applications and radii may require additional tooling preparation, such as a rougher surface for better clamping and material penetration, micro-serration (micro-tooth clamping), short tooling, and more.
Our tooling can be adapted to bend any requested material—from soft copper and brass to titanium, Inconel, and any profile shape.

One of our specializations is Multi-level (multi-stack) tooling sets for 5-, 9-, or more-axis CNC tube bending machines with vertical and horizontal movements of the bending console to position the tube between different tooling planes.
This allows the production of parts in a fully automatic cycle with several radii, transitions between classic draw bending and push bending, bends without straight sections using profiled clamps, and much more.
We are able to develop a complete tooling project for your machine, including all necessary tooling levels, holders, adaptors, and supports to ensure correct movements of clamps and pressure dies, as well as rollers and cages for push bending. During the development phase, we check all possible collisions and define the required sequence of movements.
In some cases, to prevent collisions, a specific tooling level must be used, and it is necessary to position the tube and tooling on the upper planes. We can also develop such solutions, including the use of specified spacers for lower levels.
