NDW-XCW Series 4mm/5mm/6mm/10mm/12mm/14mm Computer Control Wire Testing Machine Testing

1 Important Function

1) Wire simple torsion testing machine(wire is twisted for 360° along itselfs axial direction, it is defined one time of torsion, torsion for specific times or until wire breaking)

2) Wire reverse torsion test(wire is twisting for 360° along itselfs axial direction, it is defined as one time of torsion, twisting to opposite direction for the same times of cycle or wire breaking after twisting for specific times)

3) Simple and reverse torsion test and research with metallic wire, double strand metallic wire, composite material, bare wire, round cross sectional and special cross sectional conductor.

4) Simple and reverse torsion test with wire for plastic deformation property and defect of inner and surface.

5) Check shape and defect of breaking point(falt, ladder, diagonal, fanshaped, with crack, with sinkhole.)

6) Check crack lay of wire(constant crack and flash along torsion stripe)

7) Simple torsion with metallic, copper, aluminium and its alloy wire and composite material of diameter 1.0mm-14.0mm.

8) Reverse torsion testing with metallic, copper, aluminium and its alloy wire and special cross sectional conductor of diameter 1.0mm-10.0mm.
