It is more important than ever to maintain work piece, spindle, and machine element temperatures at a consistent level because of increasingly tight tolerance requirements. It doesn’t matter if the machine is used for grinding, drilling, milling, or honing the use of coolant chillers has become essential. A controlled coolant temperature minimizes centerline migration and heat distortion. Lower coolant temperatures can also enhance the tool lifetime as well as reduce oxidation and evaporation.

What is a Coolant Chiller?

A coolant chiller is used to cool and maintain the temperature of coolant, oil, and water in regards to the ambient temperature or a set temperature value. The underlying principle is refrigeration. The coolant used in machining is specially formulated to absorb a massive amount of heat within its molecular structure. At the same time, the structure will not radiate heat into the material it contacts. An excellent example of this is cutting oils which are used to enhance the cutting process and provide heat removal. A coolant chiller is used to decrease the temperature of the coolant after ...

Why is a Coolant Chiller Used?

Without a coolant chiller a massive amount of coolant oil or water would be needed for machining. By quickly absorbing the heat which is trapped in the coolant, the coolant can be quickly reused again and again. This allows a lower amount of coolant to be required for the machining process. Not only does this lower costs but it also extends the useful lifespan of the coolant itself. Common applications that a coolant chiller is used for includes lasers, MRI scanners, PET scanners, machine tool cutting, and vapor degreasers.

How to Effectively Compare Coolant Chillers

There are several different types of popular coolant chiller systems available. The key is to select a coolant chiller system which will meet all of the needs of its specific application. A high level of accuracy in terms of coolant temperature control is critical. The first factor to consider when comparing coolant chillers is the accuracy range. No coolant chiller is designed to maintain an exact temperature, however the best options can provide accuracy within +/- 0.5°C.

Another key ability of a quality coolant chiller is the ability to provide multiple options or settings. Some of the most commonly used options include a heater, cycle pump, internal coolant, coolant level check, fluid flow rate check, and operation our setting. The specification options allow a coolant chiller to be used in multiple different applications within the same setting.
