Spray Cooling Systems
The need for providing coolant to metal removal operations is readily accepted in machining industries. Spray cooling provides the benefits of coolants used in flood applications with the added performance of a high velocity air/coolant mixture.
It is used where high speed tools and saw blades require powerful chip clearing, and offers coolant application where flood cooling is inadequate. In addition, spray cooling is also used in processes that generate high amounts of heat at
the tool chip interface.
Delivering a low volume of coolant at a high velocity, spray cooling is able to remove heat as fast as possible, which is critical in maximizing productivity and quality. Also, it helps keep expendable tooling costs in line.
JSG Industrial Systems offers three Trico delivery systems for dispensing a wide range of coolants in many metal removal processes: siphon, pump, and pressure delivery.
SIPHON DELIVERY SYSTEMS
Siphon type units use the flow of air across an orifice to draw or pull fluid from the reservoir to the nozzle tip. There are no moving parts. These siphon type units cover a range of applications from light to moderate with up to six nozzle capability.
The use of multiple nozzles allows adequate coverage when tool sizes are large or heat generation is great. Typical locations for use would be machine shops, tool rooms, prototype areas, or small machining work cells. These
units are economically priced and can cover secondary machining applications not equipped with coolant capabilities. Drilling, tapping, milling, turning, sawing, etc. are examples of applications that can be improved with the various siphon units that are offered.
PUMP AND PRESSURE DELIVERY SYSTEMS
For more sophisticated and demanding metal removal processes, or where more than six nozzles are necessary, the pump or
pressure type delivery systems are recommended. These are also recommended for higher viscosity fluids, up to 1000 SUS.
The pump type uses a mechanical pump to force fluid from the reservoir and the pressure type uses an air pressurized reservoir to force fluid to the nozzles. With the coolant being delivered with positive pressure in either case, a wide range of coolant stream definition can be attained.
From air only to mini-flood streams, the wide range available for adjustment, allows the user to set delivery to the specific application requirements. Applications covered by these systems include dedicated secondary machines, transfer lines, conveyors, large capacity tooling, through the tool and machining cells. The multiple nozzle/valve combinations also allow for customizing systems specific to end user applications.
