Robotic Bender Type T-WIN Series

World-patented robotic bender
The machine of high-end performance for work pieces with components mounted

Product outline

Robotic Bender Type T-WIN Series
The robotic bender type T-WIN mounts speed accelerator gear box atop of 6-axes robot head, and a small-sized bending head is mounted on the output axes.
●Thanks to this feature, high speed motion is realized in all functions of straight pitching, 360-degree rotation and retraction.
●Operation of the machine is as easy as conventional bender by input of bending point data in the (XYZ) coordination
●Loading/unloading position data for the robot bender are handled in by the teaching box.
●A work piece can be chuck-held at any point of its intermediate section or at the end of work piece.

Two types of bending head are available, movable T-WIN or stationary G-WIN.

Movable bending head (T-WIN) Stationary bending head(G-WIN)
5・8・10・15・20・25 35・45・50・60・70・80・85・90・100・130・150

Operational concepts, performance and tooling share much in common and interchangeable in corresponding capacity size between Oopton's conventional benders and robot benders.

1.T-WIN : Movable bending head

The bending head unit is mounted on the robot arm end for all PRB motion with linear- and circular-interpolation implemented.

Because of a work piece kept in fixed condition, high-speed and -accuracy machining is realized with its minimal swinging. This allows machining of complicated designs, quality stability as well as cost reduction which have long been refused in conventional machines and approaches.

Conventional production method has always needed to complete work piece with components of hoses and/or blocks in post and separated process. where in very often the cases are these components fixed only after a work piece being machined. This has only increased production process and accuracy instability.

Thanks to the enhanced capability of a bending head implemented on the robot arm end allowing its maximum interference-free motion, a straight work piece with pre-installed components can be machined, and thus shortage of process and increased of accuracy stability have come to reality

Another Robot bending


  1. Method of data input and operation same as the conventional model
  2. Machining is accessible with a work piece with component at clearance position
  3. Four different designs can be machined and classified in the standard four (4) stocker loader
  4. Small R bending is in reality thanks to the power of NC mandrel
  5. Long work piece can be machined with the help of intermediate chucking
  6. With the help by one-point bender in attached location,continuous machining accessible including special designed bending.
  7. Case sample : Robotic bender in Opton’s cell system completes 24 seconds for 15 points bending of AL work piece against 1 minute of the same by conventional bender,
  8. Case sample : Successful Cell system of whole production line for air-conditioner pipe with rubber hose for its last bending process
  9. Max machining dia 16.0mm max. bending R 50mm

There are many production problems to solve, including cost-down, quality increase, production variety, one-piece production, elimination of running stock, instant full start-up, etc., and they are all in most cases hard to be cleared by conventional type of benders. Robotic benders from Opton are just the ones for solution at high end level.
