High-pressure coolant systems.

Maximising efficiency with advanced cooling technology.

The implementation of high-pressure coolant systems is a decisive step towards significantly increasing the performance of your CNC machining centre. In this process, the coolant is fed through the work spindle directly to the cutting edges of the tool. As the use of cooling lubricants for lubrication, cooling and, in particular, chip removal is generally indispensable, this sub-system should be given special consideration when investing in a machining centre.

Variants of Coolant systems.

We offer our compact Coolant systems in three different versions. If the use of a centralised Coolant system is not possible, HEDELIUS offers an economical alternative with the inclined bed filter system. The inclined bed belt filters are characterised by a high filtering level and low paper consumption.

Coolant system SKM 500

Clean tray capacity: 500 litres
Filtering level: 1.0 mm
Filter capacity: 180 litres/min
Pump output: 2.0 bar 150 l/min

Separate standing Coolant system with removable steel plate filter insert.

Coolant system SKM 900

Clean tray capacity: 900 litres
Filtering level: 190 µm
Filter capacity: 180 l/min
Pump output: 2.5 bar 150 l/min

Separate inclined bed belt filter coolant system incl. automatic paper feed, fill level monitoring and steel sieve pre-filter above the filter felt for separating aluminium and plastic chips.

Coolant system SKM 1400

Clean tray capacity: 1400 litres
Filtering level: 190 µm
Filter capacity: 180 l/min
Pump output: 2.5 bar, 150 l/min

Separate inclined bed belt filter coolant system incl. automatic paper feed, fill level monitoring and steel sieve pre-filter above the filter felt for separating aluminium and plastic chips.

Other accessory options.

With the help of a wide range of additional equipment options, a Coolant system can be customised to your individual machining task. For example, an immersion cooler offers a high level of process reliability thanks to the active and controlled cooling of the lubricant by counteracting heat input into the material and tool. A belt skimmer for separating floating oils prevents contamination of the coolant. Furthermore, equipping the system with additional sensors can significantly simplify time-consuming maintenance work.

Immersion cooler

**For maximum accuracy

An immersion cooler with integrated agitator keeps the coolant temperature constant. This not only increases the service life of the cooling lubricants, but also benefits the accuracy of the milling process.

Oil skimmer

**For sustainable oil separation
Optimal is the connection of the agitator with an integrated oil skimmer. Thanks to the separate power connection, the cooler, agitator and skimmer also run during non-production times, e.g. at weekends or on public holidays.

Concentration and temperature sensor

**For improved coolant maintenance
The optional equipment of the Coolant systems with digital sensors for measuring concentration and temperature considerably simplifies coolant maintenance.

Internal coolant supply

**For greater process reliability

Depending on the application, the systems can also be equipped with high-pressure pumps of 25, 50 or 75 bar. By supplying coolant under high pressure, the tool edges are cooled and wear is avoided.

Belt filter Coolant system with belt scraper

**For optimum machine performance
The separate belt filter Coolant system is equipped with a belt scraper that removes aluminium and plastic chips from the belt and discharges them into a separate chip accumulation container. This ensures efficient cleaning and removal of the chips.

Programmable coolant pressure.

In conjunction with an internal high-pressure coolant supply, a frequency converter is installed as standard to control the speed of the pump. As not every tool or process requires the full pressure, the coolant pressure and therefore indirectly the energy consumption can be set individually for each tool directly in the NC programme using the speed control. As a rule of thumb:

20% speed reduction leads to 50% energy savings

50% speed reduction leads to 80% energy savings

Chip press.

HEDELIUS also offers a user-friendly and sustainable solution when it comes to recycling coolants. By connecting a chip press to your machining centre, the chips produced in the chipping process are separated from the cooling lubricants. The adhering cooling lubricants are almost completely pressed out of the chips and returned to the chip conveyor. In addition, the volume of the chips produced is reduced by up to approx. 80 % during the briquetting process. This allows you to produce profitable recyclable materials from waste materials that are to be disposed of.
