CNC Automatic Eye forming line ER3F

ER3F eye forming machine with positioning device

1 Steel bar thickness             8-25mm

2 Steel bar width钢                   44-120mm

3 Min. inner diameter of eye     Φ19mm

(D/T≥2, D: Inner diameter of eye, T: Thickness of leaf)(Diameter less than Φ25 will not be guaranteed the precision, the mandrel life will be shorter)

4 Max. inner diameter of eye forming    Φ80mm

5 Length between two eyes              1060-1900mm

6 The distance tolerance between two eyes    ≤±1.50mm

7 Parallelism of eyes                          ≤1%

8 Perpendicularity of eye                        ≤1%

9 Allowance of inner diameter of eye      ≤0.3mm

( D/T≥2,  D:Inner diameter of eye,  T:Thickness of leaf ) (Note: deduct the effect oxide scale, except the leaf springs with rectangular section)
