There are a number of benefits to applying high pressure coolant using the “on demand” Coolant system made by COOLJET.

For instance, if you are targeting to reduce process cycle time - you will find that your tool life was significantly extended after applying High Pressure Coolant.

Its applications are extensive from drilling, grooving, boring, cutting of hard metals which have a high nickel content, to small tooling applications etc.

“During the metal cutting processes, significant heat is generated at the tool and workpiece interface, primarily from the effects of friction, which can be detrimental to the tool and the workpiece,” DIMAC Director Paul Fowler explains. “With the on-demand Cooljet coolant system cutting fluids are pumped to pressures of 1000psi (70 bar) or more, and are accurately directed to the cutting zone through an appropriate nozzle. The resultant jet stream of coolant is able to penetrate the high temperature cutting zone, delivering vital lubricants to the cut.”

“Temperatures are dramatically decreased due to the reduced friction,” he goes on to explain. “This is very evident by observing the chips produced which are well formed and are generally not heat discoloured. The coolant system also effectively forces chips away from the cutting area especially in deep-hole drilling or pocket machining.”

COOLJET Systems produces an ultra-high pressure coolant supply by pumping coolant through small orifice tools or nozzles, to deliver an acute, high velocity jet stream which penetrates the friction zone between cutting edge and workpiece, providing superior lubrication, cooling and chip removal. The COOLJET Systems improves workpiece quality, reduced process time and increases tool life.

“If you are targeting to reduce process cycle times, you will find that your tool life will be significantly extended, and the quality of the cut is considerably increased after applying high-pressure coolant," Mr Fowler says. "Its applications are extensive from drilling, grooving, boring, cutting of hard metals which have a high nickel content, to small tooling applications.”

It is ideally suited to large size tooling and multi turret machines; COOLJET is capable of delivering both high and low pressure to each turret independently.

The variable flow “Pump on Demand” feature assures that a constant pressure is maintained at the tools in use.

The COOLJET range consists of a number of models from the MINI series through to the UltraFlex, which allows you to install a system suitable to your needs
