NDX-10 Metal Wire Torsion Testing Machine
Chức năng chính: Torsion Test Machine
The series Metallic Materials Wire Reverse Torsion Test Machine mainly used to test the capacity of bearing deformation of the metal wires and other wire ropes whose diameter are φ0.1~φ10mm during the reversing. The test can show the surface defects of wire during the test process.
Đặc trưng
The testing speed (revolutions per minute) is optional, such as 30, 60 revolutions per minute.
It can clamp wire material with length of 500mm; LCD display the testing revolution. The number of testing revolution will blockade automatically after specimen fracturing.
Principle
A test piece of wire is twisted a specified number of turns through 360° around its own axis in one direction, and then a specified number of turns through 360° in the opposite direction.
The grips shall have a minimum hardness of 55HRC to provide rigidity and/or resistance to abrasion. The grip shall be arranged in the testing machine in such a way that, during testing, during testing, they remain on the same axis and do not apply any bending force to the.
The distance between the grips shall be capable of adjustment for different test piece lengths.
