Grinding Fluids
Grinding Fluids
Points : Grinding Fluids, Water-Soluble Chemical Fluids, Water-Soluble Oil Fluids
Cutting fluids are an important factor in lessening the wear on the cutting tool, They
help to maintain accurate dimensions and are quite important to the quality of the
surface finish produced. The coolant is very important if the heat produced during the
grinding operation is to be carried away at the rate it is generated. Several type of
coolants are used for grinding operations:
1. Water-Soluble Chemical Fluids
This is the solution that takes advantage of the excellent cooling facility of water. It is
transparent and includes a rust inhibitor, water softeners and detergents to improve
the leaning ability of water and bacteriostasis (substance which regulate and control
bacteria growth). Polymers are added to improve lubricating qualities.
2. Water-Soluble Oil Fluids
This coolant also takes advantage of the excellent cooling ability of water. It is usually
milky white.. It is less expensive than most chemical type fluids. Bacteriosasis is also
added to control bacteria growth. The coolant can be applied by flooding the grinding
area. The fluid re-circulates by means of a pump and tank system built into the
machine. A mist system forces the coolant through the wheel or applies it at the work
surface under pressure (air) and cools by evaporation. A coolant can also be applied
manually by pumping the fluid from a pressure type oil pump can. For safety, the
coolant system should be cleaned at regular intervals. Cleaning means removing all
dirt and sludge from the storage tank. Discard the fluid when it becomes
contaminated.
