SAFETY PRECAUTIONS
The Pin on Disc Friction & Wear Test Rig is an electro-mechanical Device. Please
follow the instructions carefully.
Personnel injury may be resulted by improper operation.
The equipment may be damage by improper operation.
Only our service engineer installs and services the equipment.
Please ensure proper earthing.
Voltage between Earth and Neutral should be less than ±5 Volts.
Do not attempt at wire circuitry while power is ON.
Do not attempt to examine the components and signals when the equipment is ON.
Do not attempt to disassemble or modify internal circuitry or wiring.

DESCRIPTION
The Pin on Disc Friction & Wear Test Rig is intended for determination of tribological
properties of different materials.
(i) Ascertain the validity of law’s of friction
(ii) Wear characteristics of the given specimen
(iii) Determination of wear constant
(iv) Understand the effect of parameters
This is a study versatile machine, which facilitates study of friction and wear
characteristics in sliding contacts under desired conditions. Sliding occurs between the
stationary pin and a rotation disc. Normal load, rotational speed and wear track diameter
can be varying to suit the test conditions. Frictional force and wear (displacement) are
monitored through electronic sensors and recorded to PC.
The major parts of the wear and friction monitor are mechanical assembly, Base plate,
Guide Base, AC Motor, AC Drive and spindle assembly, loading arrangement with 1:1
leverage ratio with a pulley, loading pan with dead weights, wear disc holder, scale to set
the track radius, LVDT for displacement, and load cell for frictional force.
