This testing system allows up to 14 specimens to be polished simultaneously on a rotating road wheel that interacts with a solid rubber tyre under spring load. The machine features dual mechanical feeders for continuous abrasive supply (corn and flour emery), placed on a detached support frame to reduce vibration effects and preserve calibration integrity.
The unit includes a digital control panel displaying wheel rotation speed and test countdown. A built-in water container with a flow regulator ensures a controlled supply during polishing. The polished specimens obtained are perfectly compatible with Skid Resistance Testers for further frictional analysis.
Supplied with:
- 2 rubber wheels (for corn and flour emery)
- 4 specimen moulds
- 2 mould covers
Abrasive materials and control stones must be ordered separately.
