We are your source for high quality tube fittings, intricate and high volume tube shapes, certified integrators to swage your fittings and prepare your tubing, all backed the Swagelok Limited Lifetime warranty.
CNC tube bending is ideal for:
- Tubing shapes that are needed repetitively
- High volume tube bending projects
- Tubing shapes needed for R&D purposes
- Reverse-engineering of tube shapes to create specifications for future use
- Intricate or unique tubing shapes
- Tube bends that must meet demanding tolerances, such aerospace requirements
California Analytical Instruments gave automated tube bending a try. Here's what they learned.
What is CNC Tube Bending?
Automated CNC (or Computer Numerically Controlled) tube bending is an alternative to hand tube bending and welded pipe and can reduce the number of fittings needed to meet space requirements. San Diego Fluid System Technologies was one of the first to offer CNC tube bending on an Eaton Leonard machine in the San Diego area. A new state of the art bending machine was recently installed. We also offer hand tube bending by certified integrators, tube bending training for its’ customers and hand tube bender rentals.
Don't have drawings or measurements?
Our portable Vector Measurement arm can measure from existing parts or our engineering team can work with a simple sketch to create bends from the ground up.
Do you have:
1. A skilled workforce to deliver accurate specifications by hand bending?
Hand tube bending is a skill that takes some training to master. Automated CNC tube bending overcomes the potential for human error because it uses a vector measurement machine to measure exact coordinates, which are then sent to the bender itself and recreated. Scrap is eliminated because the bender is precise and you purchase only the finished product.
Tube bending is not often an ongoing process for many companies. Occasional projects that incorporate tube shapes can be distracting, reduce throughput and tie up resources that could be utilized elsewhere. An experienced tube bending partner can take the load off your company and provide bent, pre or fully swaged parts that are ready to use.
2. The workforce and space to deliver and store large quantities of bent tubing?
An automated CNC tube bending partner can save time and cost, simplify and add efficiency to your projects. Parts are created in a fraction of the time that it would take to accomplish manually. Your team can focus elsewhere and you can utilize floor space at your facility for other purposes.
Tube bends can also be integrated into panels and other assemblies at our local Swagelok Custom Solutions facility. You receive ready-to-install parts, with no waste and less busywork for your team. The tube bends and tubing assemblies provided by San Diego Fluid System Technologies are also backed by the Swagelok Limited Lifetime Warranty.
3. Specifications for existing tube shapes or reverse engineering?
San Diego Fluid System Technologies now offers a portable, highly accurate measurement arm that can be taken to your jobsite to measure existing parts, creating a specification that can be stored for later or automatically sent to the CNC bender to recreate your parts. Additionally, if you need design changes to existing parts, these specifications can be used as a base.
4. Unique or coiled shapes?
The new CNC bender, an electric Eaton Leonard VB 25 DR, is well suited for small geometry and complex shapes, such as coils. It does this with a dual rotation arm that works clockwise and counterclockwise, essentially working as a left hand bender or a right hand bender.
Applications requiring 1/4”, 3/8” and 1/2” wall thickness with “heat exchanger-like” geometry will be able to be executed upon.
