BENDING ROLL
Standard machine serie
Customized machine series
BS-B Pinching type 4 rolls

Ideal 4 rolls bending machine Edge bending is possible with 4 rolls machine which 3 rolls machine is impossible. (Center adjustment is equipped)
Processible Dimensions at Machine

- The pre-bending processing is not required. From edge bending to cylindrical forming is possible in one process.
- All rolls are quenched and grinded, so stainless steel or aluminum can be processed without any damages on surface.
- The roundness is accurate by locking side roll (No1 to No3) perfectly after upper position.
- The barrel shape or conical shape cylinder formation is prevented by synchronized mechanism for roll balance with adjustment of center bearing.
- Repetition of bending production is simple with setting up the numbers by dial type setting meter.

1.Work supporting roll (option)
Preventing the deformation of roundness from work's weight and provide stabile processing by supporting roller, which located beside of roll.
2.Work suspension device (option)
Preventing the work's one end and other end to be feed and bend at once when work processed diameter is smaller than expected or bend with work's weight.
