Materials Testing Machines with Torsion Drive

Torsion drives from 2 Nm to 2,000 Nm are available for torsion tests on materials or components. Zwick supplies a variety of testing machines to cater for different requirements, including varied installation options.

100 kN materials testing machine with torsion drive

These torsion drives were developed as a modular system, making them suitable for retrofitting also. A Master test program for multiple test axes plus a graphical sequence editor for four test axes are available in the testXpert II testing software. For pure torsion tests there are the TorsionLine testing machines with horizontal testing axis and optional weight loading unit. Users of all these machines have the benefit of testControl measurement and control electronics.

Modular design allows retrofitting of these torsion drives as and when required.

Key Advantages and Features

  • Modular design allows retrofitting of torsion drives as and when required
  • Operation with standard PC or laptop (no additional interface card required) and testXpert II testing software
  • High-resolution rotation angle and travel measurement
  • Easy handling and user-friendly operation for maximum flexibility
  • Synchronization of both test axes
  • Optional CE-compliant safety device for use with hazardous specimens and / or higher rotational speeds
