Introduction to Abrasives
An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away
Abrasives generally rely upon a difference in hardness between the abrasive and the material being worked upon, the abrasive being the harder of the two substances.
The abrasive and the material to be worked are brought into contact while in relative motion to each other. Force applied through the grains causes fragments of the worked material to break away while simultaneously smoothing the abrasive grain and/or causing the grain to work loose from the rest of the abrasive.

Factors affecting Workpiece Abrasion
Difference in hardness between the two substances: a much harder abrasive will cut faster and deeper
Grain size (grit size): larger grains will cut faster as they also cut deeper Adhesion between grains, between grains and backing, between grains
and matrix: determines how quickly grains are lost from the abrasive and how soon fresh grains, if present, are exposed
Contact force: more force will cause faster abrasion Loading: worn abrasive and cast off work material tends to fill spaces
between abrasive grains so reducing cutting efficiency while increasing friction
Use of lubricant/coolant/metalworking fluid: Can carry away swarf (preventing loading), transport heat (which may affect the physical properties of the workpiece or the abrasive), decrease friction (with the substrate or matrix), suspend worn work material and abrasives allowing for a finer finish.

Abrasive Selection Factors
Application determines use of appropriate abrasive Excessively hard abrasive wastes money by wearing
it down when a cheaper, less hard abrasive would suffice.
Too soft, abrasion does not take place in a timely fashion, effectively wasting the abrasive as well as any accruing costs associated with loss of time.
Different chemical or structural modifications may be made to alter the cutting properties of the abrasive.

Excessive Vibration can lead to Permanent Disability
Control of Vibration at Work Regulations 2005 The Control of Vibration at Work Regulations 2005
(the Vibration Regulations), came into force on 6 July 2005 and aim to protect workers from risks to health from vibration.
The regulations introduce action and limit values for hand-arm and whole-body vibration.
