NDW-XC1/XC3 High Speed Wire Torsion Testing Machine

1 important function

1) Wire simple torsion test(wire twisting for 360° along one direction of axial direction of itselfs  is defined as one time of torsion, twisting for specified times or breaking.)

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

3) Simple and reverse torion test and research with metal wire, double strand metal, compounding material, bare wire and round cross section and special cross section of conductor.

4) Simple and reverse torsion test for bearing property of plastic deformation and defect of surface and interior.

5) Check shape and defect of breaking point(flat, stepped shape, sideling, fanshaped, with cracking gap and sinkhole.)

6) Check crack layer(constant crack gap and flash along torsion stripe)

7) High speed simple torsion test with metal wire, aluminum, copper and its alloy, composite material of diameter 0.1mm -- 3.0mm.

8) High speed bidirectional torsion test with metal wire, copper, aluminium, special cross section conductor, composite material of diameter 0.1mm - 3.0mm.

2 Standard.

1) ISO 7800 2012 Metallic materials -Wire-Simple torsion test.

2) ISO 9649 Metallic materials-Wire-Reverse torsion test.

3) ISO4101 Drawn steel wire for elevator ropes-Specifications.
