eXpert 8600 | Axial-Torsion Tester

ADMET offers a full line of table top and floor standing axial-torsion test machines. Our eXpert 8600 Axial-Torsion testing systems come equipped with our powerful MTESTQuattro controller making them ideal for testing a wide range of materials and devices like screws in torsion, medical implant and body fusion devices, luer taper fittings, adhesives, and biomaterials.

The eXpert 8600 features high axial and torsional rigidity and have oil-free linear and rotary actuators for clean room operation. They also feature unlimited torsion actuator rotation, wide column spacings, and large actuator strokes for maximum flexibility.

ADMET also offers a full line of axial-torsion grips and chucks. Specimens can be tested in an optional fluid bath with heating and cooling for producing the desired physiological environment. A variety of low-force load and axial-torsion transducers are available to meet your needs.

Featured Configurations

eXpert 8600 for ASTM F543 Testing

The eXpert 8600 equipped with the MTESTQuattro controller is specially configured to test metallic medical bone screws according to ASTM F543.  Included with the system is the required fixturing to perform the four test methods outlined in Annexes A1-A4. ADMET MTESTQuattro software comes preloaded with these test procedures. To run a test, the operator needs to install the correct fixturing in the machine and select the appropriate test method from the menu.

  • Software preloaded with ASTM F543 test methods Annexes A1-A4
  • Axial load capacity up to 2.2kN (500lbf), Torque capacity up to 20Nm (180 lbf-in)
  • Includes:
    • Keyless hand chuck mounted on drive spindle
    • Collet Screw Clamp System (Annex A1)
    • Centering Machine Vice (Annexes A2, A3 and A4)
    • Pull Out Adapter (Annex A3)

eXpert 8600 for Solid Ice Specimen Testing

The eXpert 8600 configuration for testing solid ice specimens was amongst the slowest moving 8600 series machines built with speeds down to 0.8 degrees per minute. The testing system was equipped with an environmental chamber and a custom-designed fixture for ice specimens to allow very precise angular movements. In addition, backlash kits with adjustable spring loaded fixtures were included to preload the axial actuator in compressive and torsion CW and CCW directions.

  • Axial load capacity up to 5kN (1,125lbf), Torque load capacity up to 50Nm (445 lbf-in)
  • Full range of speeds:
    • 0.000001 to 0.36 ipm axial rate, 0.0000003 to 0.01 rpm twist rate
  • Two different speed ranges at high gear/low gear:
    • Axial: 0.36 ipm (low gear) and 0.03 ipm (high gear), Torsion: 3.6 degrees per min (low gear) and  0.0001 degrees per min at (high gear)

eXpert 8600 for Watch Band Traction-Torsion Testing

This configuration of the eXpert 8602 is designed to perform traction-torsion testing on watch bands. Specialized test fixturing and the option to include environmental chambers with humidity control allow users to perform traction-torsion and tension tests to determine the lifetime of the band in various simulated conditions. Testing can be controlled by either torque or angle set points.

  • Axial capacity up to 2.2kN (500lbf), Torque capacity up to 20Nm (177lbf-in)
  • Axial speeds up to 178mm/min (7ipm), Twist rate up to 60 rpm
  • Specialized fixturing to test watch bands, accommodating both tongue buckle and folding buckle designs
