The use of coolants in machining has undergone an array of changes over the past several years. Traditionally, machine shops were primarily reliant on using coolant in a convention manner. This entails flooding the operational zone with coolant during the machining process. Unfortunately, there are a variety of circumstances in which conventional uses of coolant are insufficient. As a result, a growing number of machine shops are now turning to a high pressure coolant system to boost productivity and the end-results.

What is a High Pressure Coolant System?

Contrary to its name, a high pressure coolant system is more than simply an increase in pressure; it is creating a precisely controlled coolant flow rate and outlet size from the system pump to the tool being used. By reducing the fluid outlet size the fluid velocity will increase. The total number of nozzles will greatly affect the fluid outlet pressure as well. This process is based upon the Bernoulli theory which notes the relationship between pressure, fluid flow rate, and velocity of a fluid - in this case coolant.

Using a High Pressure Coolant System to Control Chip Formation

A key benefit of a high pressure coolant system is efficiency when it is used correctly. Simply flooding the machining zone with coolant is no longer enough because it is applied inefficiently. When the disbursement of high quality coolant is controlled in a laminar flow, it shortens the actually contact length between the chip and rake face. This is achieved by creating a hydraulic wedge between the chip and rake. The wedge is critical to reduce tendency for a built-up edge. As an added bonus, the cooling effect also makes the chips more brittle and easier to break.

Using a High Pressure Coolant System to Control Heat Generation

If conventional cooling methods are used with today’s high machining rates the likelihood of instant evaporation is high. This should be avoided as it leads to the formation of a pressurized vapor zone. If a pressurized vapor zone exists during the machining process it will prevent the effective flow of low-pressure coolant to the cutting edge. A high quality coolant system utilizes strategically directed jets of coolant to reduce the contact time between the chips and insert which limits the amount of heat generated. Reducing heat generation in the machining zone will prolong tool life, create the potential for a higher cutting speed, and decrease tool wear.

Benefits of an Optimized High Pressure Coolant System

A high pressure coolant system also offers the potential for a variety of additional benefits as well. Reducing heat and friction can reduce tool wear to dramatically extend the useful lifespan of the tool. It provides additional control over how chips are formed and how quickly they are broken and removed. The improvements in the production process offered by a high pressure system leads to a more efficient utilization of available machines and decreasing overall production time. The result of an optimized system is maximized profit margins by significantly reducing production costs.
