This is a brief outline of NISSIN 3D Freeform Tube Bender (NISSIN CNC Pipe Bender) and our company profile. [Overview] With the NISSIN CNC 3D Freeform Tube Bender, it is possible to bend different radii at tubes and profiles in three dimensions without tool change. This is due to a patented tooling in combination with a CNC control system. Radii can follow each other without straight length in between, and can be in different planes. The machine can produce bent tubes with homogeneous wall thickness. Using a mandrel, thin-walled pipes be bent on the NISSIN CNC 3D Freeform Bender, up to a diameter of 60.5 mm. The smallest radius that can be achieved is somewhere around 3DR (depending on material tube specification.) The 3 axis system can bend round tubes only with suggested thickness 5 - 10% of O.D. The Easy Programming software on Windows has features like 3D preview, mirroring and rotation, Pls refer to these articles for technical basics: Tube bending with no straights?

2. What is NPB?
• NPB (Nissin CNC Pipe Bender) is an unique, 3-D
freeform tube bending machine that can bend tube
sections with no or small straight sections
between bends. !
• Different radii requires neither tool changeouts
nor time-consuming tooling setups. !
• Instead, an operator changes parameters in our
proprietary “previewable" machine control
software.

4. Advantages
The Nissin CNC 3D freeform tube bender offers extraordinary advantages over
conventional tube bending machines. !
With the Nissin, a tube is continuously guided through a single die according to the
programmed specifications. !
This single die technology offers flexibility in part design which is unmatched by other
forms of bending.!
!
Advantages using the Nissin over conventional tube benders include:!
! • The ability to produce multi-radii parts without additional tooling.!
! • This greatly reduces project costs for the customer.!
! • Little to no distance required between bends.!
! • Ability to produce angles greater than 180 degrees.!
!
Minimal set-up and lead times are achieved for even the most complex parts making
this bender ideal for the production of prototypes to high volume production.!
!
Despite these beauties with the Nissin, there are a few limitations.!

14. 1) Applicable tube materials?!
Basically, applicable tube should be made of steel, stainless, !
or aluminium. !
(In JIS standards: STKM, SGP, SUS304, SUS316, A5052, A6063.)!
!
2) Min. bending radius?!
3 * O.D (Please refer to the figure.)!
ex. in case of φ25 tube 3DR is 3 * 25 !
= 75R is the min. bending diameter.!
!
3)Max. bendinding radius!
No limit. But under 30DR is recommended for accuracy control.!
!
4) Thickness of tube?!
In general, the thickness should be within 5~10% of the tube !
outside diameter, for safety.!
!
5) Can I bend round bar?!
No, you can not.!
NPB can bend only tubular metal made of steel, stainless steel,!
and/or aluminium.!
!
5) Oval shaped, or other non-circular shaped tube applicable?!
No, you can not.!
!
6) How about repeatability?!
In general, within ±1 degree (per bend), but it depends on the!
tubes' specific attributes. Trial bending is required with the material !
tubes available in your market. Our reference specification is JIS.!
!
Frequently asked questions
7) How about bending speed?!
In general 100mm/sec. for both NPB-030M and NPB040M, and !
50mm/sec. for NPB-050M. Please refer to the demo movie on !
Youtube.!
!
8) Programming easy?!
Very easy.!
Please refer to the previous page for sample program code.!

9) What is the dies materials?!
A special sort of wear-resistant ceramic.!
!
10) Approx. lifetime of dies?!
In general, approx. 200km in material length but it depends on !
the quality of tube materials and how hard you bend it.!
!
11) Easy dies change?!
For a normal operator, it would take just 20 - 30 min.!
If the O.D. remains the same, you do not have to change anything.!
!
Very easy comparing with the conventional type of tube bender !
which requires time-consuming dies change.
