  High Frequency Reciprocating Rig

Purpose
To characterise friction of ball on disc contact under dry or lubricated condition. It is particularly suited for evaluating low lubricity fluids like diesel.

Description
A plate is mounted on a temperature controlled stage. It is pressed against a reciprocatory ball with known force. A piezoelectric force transducer senses the instantaneous value of the frictional force. The movement of ball is generated by a balanced scotch yolk mechanism.

Standards
ASTM D 6079
CEC F-06-7-94

Features
Automated testing.
PC based data acquisition and presentation.
Online measurement of friction.
Presettable PID control of temperature with over temperature alarm.
Measurement and display of test load by a load cell.
Four bar mechanism with hinges for reliable measurement of friction.
Programmed test sequence for automated testing.
Easy, on the site re-calibration.
Speed controller to vary test frequency.
