Applications of Cutting Fluids

Applications of Cutting Fluids - The coolant/cutting lubricant may be applied to the tool or cutter by

(i) Hand (using a brush),

(ii) Means of a small drip tank attached to the machine or by

(iii) A pump which is driven by the machine and pumps the fluid from a drain sump.

For heavy and continuous cutting, the pump system is the only one which can be said to effect proper cooling of the tool. Some attention has also been given to forcing the lubricant upward between the tool and the work for turning operations and it is claimed that this method is more efficient than feeding from above.

Generally an overhead flow is used as well to reduce fumes. Generally each machine (e.g., a turret lathe) has its supply and circulating system of the coolant. There is a pump and the piping for supplying a continuous stream of coolant to the turning or other tools. Some plants have a general distributing system for cutting fluids.

Two types of systems are in use for delivering oils and compounds from a central station to machines in the shop. One of these is arranged to pump the purified cutting fluid upto a storage tank from which it flows by gravity to the machines on different floors. The other pumps the coolant directly to different machines.General distributing systems are applicable when a single class of cutting fluid can be used throughout a plant or department.
