The IMPERIAL OFT - High Frequency Friction Machine is a versatile test instrument for the evaluation of lubricants and the friction and wear properties of materials in dry and lubricated reciprocating sliding or rolling/sliding contact conditions. It is an advanced research and development tool for lubricants, materials, coatings and surface treatments.  This is a similar version of  Cat. # 009-0072  IMPERIAL HFRR –Automated but with additional enhanced capabilities (like load, frequency, amplitude and temperature)

STANDARDS:

Description:

The OFT-High Frequency Friction Machine is supplied with its own floor standing bench and with a bench-top control unit incorporating a Interface Module, which is connected to a host PC with TRIBOTECH CONTROLLER sequence control and data acquisition software installed. The system provides sequence control of load, frequency and temperature plus data acquisition of measured parameters.

MOVING SPECIMEN:

The moving specimen is mounted in a specimen head. A number of geometries can be accommodated by using a range of simple clamping fixtures. The specimen is oscillated mechanically against the fixed lower specimen. This test rig constitutes of Electromagnetic drive enables the user for enhance loads up to 200 kg’s, and higher temperatures of up to 900°C (as optional).
