A vertical pillar contains the main spindle for each cam to be rotated, whilst a dial gauge has its anvil resting on the top edge of the cam. Each cam is mounted on a central shaft and is free to rotate about this shaft. The cams are rotated by hand.
The rise and fall displacement of the cam, as it rotates through 360°, is measured using a dial gauge. The angular position of the cam is shown on a protractor and a pointer, this assembly allows the cams position through rotation to be recorded. Cams and followers are easily changed and graphs for the variety of cams can be created to compare the linear change with the rise and fall of the follower.
A set of cams are supplied as standard along with a set of followers which run on the perimeter of each cam. Each cam can be easily changed and the angular and dial gauge readings are clear.
