■ Queries on bending works
Wear and gall of tooling are serious problem in bending of stainless pipes. Are there any good way suggested to keep quality of molding dies and wipers?
《Comment from Opton 》

1.For longer wiper life
① Galling shall occur when a stainless work piece and metal tooling rub against each other, To avoid this wiper die is generally made from non-ferrous alloy represented by aluminum bronze or beryllium copper.

②Wiper die can stay free from galling by using rather soft metal like non-ferrous alloy, but with adversary disadvantages of sharp wear of the die. 

③Wiper die needs be made sharper towards its edge, failure of which would immediately lead to wrinkles produced in inside wall of a work piece.  For its prevention the die must need shape-tuning and/or total remake in repeated frequencies

《Opton's proposal》
Opton original 『Wiper-integrated bending roll』 is proposed for solution.
This unique wiper-integrated mold has be realized by fundamental and innovative review of mold design and has achieved the service life of many ten's times longer against ordinary set of mold and wiper.
※ For detailed information, please visit 「Bending tools」 .

2.Protection of tooling (mandrel and pressure die inclusive) from galling
①Molds with TiC-N coated are supplied as standard specification for working with stainless work piece.
※In preparing molds, the best-suited quality of material and coating will be employed to meet individual machining conditions.

②Proper selection of lubricant media must be considered to meet machining conditions that varies among the specifications of production parts.

≪For any particular concern, please free to contact Opton to help finding solution.≫

Five popular questions about T-WIN Series
Case 1
  • Q  Power-shortage error is found with the encoder battery in the first working day after holiday.
  • A. This error is caused by power shortage of the robot' battery. Battery replacement is needed.

Case 2
  • Q.  What is the case where "teaching" must be involved in machining by the machines in the Robot Bender Series.
  • A. "Teaching" is not basically involved in relation to the creation process of the bending data. The "teaching mode" is employed for two robot functions, or "loading of a work piece to the chuck" and "unloading of a completed part into specified position".

Case 3 
  • Q. Is it a must for machine operator to join training course of handling the robot? 
  • A. The 「Ordinance on Industrial Safety and Health 」 regulates that the training on the teaching work and maintenance of robots must be held by qualified person who has completed the course of 「Special Training of handling the robot」. Under this regulation, the training course will be held by the Opton's qualified specialty at a client premises. Operators can also attend to a robot operation school held by the robot manufacture.In either course provided are handling manners of the robot and robotic system, daily cares as well as total maintenance with the contents organized to meet the request by user's operators.  

Case 4 
  • Q. Is the cable consumable material that is supplied in a package of the machine? 
  • A. Basically yes. The cable is replaced by a new one in a periodical maintenance check by Opton engineer. The cable supplied in a package of the machine is intended to be for quick maintenance by machine user himself.
  
Case 5
  • Q. T-WIN 25 in Opton HP shows the figure 1000mm/sec as the standard velocity of DBB. Can this speed be modified to higher speed?
  • A.  Yes, higher speed is possible.Listed speed is just the "standard" figure, which can be modified to meet user's tact-time requirements.

What are the max allowable length of work piece that can be accepted by Opton profiling machines ?
There is basically no limit of work piece size for profiling by the Croudforma Ⅲ

A work piece is placed for testing on the surface plate with position marking. 
The surface plate with position making is sized 700 x 1000 mm as standard, and these sizes eventually indicate the size limit of a testing work piece.
For longer-sized work piece, the surface plate is also available for 1800 x 1000 mm. Other sizes can also be custom-made. 

For work piece larger than the space of the surface plate, divided profiling may be applied.



Is there any way good for improving tool setting time and set-up repeatability?
Opton's fully electric-powerd Pipe Benders have all motion axes servo-driven and numerically controlled.  
Simply by modifying the setting values of the molds through the operation window, minutest setting adjustment can be achieved easily. Once the molds are set, the setting data are saved for individual part number and the data can be up-loaded to exhibit on the display for identical set-up of the mold whenever the same part is going to be machined again. With Opton's fully electric-powered pipe benders, cutting of set-up time and enhanced set-up repeatability can be achieved.

Features

  1. All axes by AC servo driven are employed for speed-  and  accuracy- oriented motion with enhanced easiness of N/C supported tool set up.( E-ranked )
  2. Thanks to chainless and single-linked two-motor structure, the compacted bending head and eventual envelope spade, collision of work piece to the mechanism is minimized.
  3. Fully dust-proved controller box (Totally closed air-conditioning is implemented.) Controller system is protected in safe more than before from errors attributed to severe ambient condition as well as under normal services.
  4. Work piece L/R positioning by NC,  No calibration needed for tool setting
  5. Pressure-die motion by NC enabling its easier positioning that varies among parts



What are the advantages of Opton's 「CNC Pipemulti bender」?

Simply by inputting machining data to the computer bending can be achieved for restriction-free designated bending R and bending design yet with no tooling change needed as long as material diameter remaining the same..  No clamping space needed on the tool for easier execution of continuous R bending.  Quick proto-type work can be easily met.  Continuous-R bending can be met and no chucking space needed on a work piece. Since bending with low flattening and small thickness reduction can be met, parts with high-profiled design can be best suited to this machine model.

Explain the difference in bending data creation for the robotic bender between those for "center-work chucking mode" and "end-work chucking mode ."

For center-work chucking mode (bending to be completed for each half side of work piece)

One full data package includes all bending data for both sides of a full work piece, or the data for left-bending and right-bending.  There is no need to down load the data of two areas separately. 

For end-work chucking mode, the bending data are to be prepared in the same manner as those for standard bender with chuck installed for holding a work piece at its end.

Any advice available for easier tooling set-ups and for enhanced repeatability ?
Opton employs easiest 「Tool setting in package」 which does not need calibration of the installed tools. Installation positioning remains unchanged for care-free repetitive production




What is the advantage with horizontal travelling of the clamp die for ECO series pipe benders.
When a clamp die moves upwards in a conventional toggle motion and clamp a work piece, a pushing force is normally given to the work piece causing its subtle but unneeded rotation. 
Horizontally sliding motion of the die has freed this problem. 

Longer stroke distance has become available than the toggle mechanism, leading to easier bending at higher profiled specification.
※The machine with toggle mechanism still available.



What are the trial chances of bending available at Opton's premises?

The difference between CNC Multibender and CNC Pipe Multi Bender

CNC Multibender can meet bending of materials including pipes and non-pipe materials with regular and irregular cross-section designs. 


CNC Pipe Multi is exclusively for bending pipes that has intrinsically symmetrical cross section design where twisting of work piece is unlikely during bending process.  For bending materials of irregular cross section design like those for vehicle door sash and mold, twisting of material is unavoidable due its eccentric or asymmetric design of cross sections. Opton Multibender has an extra axis to control over this twisting amidst bending.
