UNIQ DirectCool: Dezentrale Kühlung für maximalen Effekt  

Funktionserweiterung der Hydrodehnspannfutter UNIQ von MAPAL durch intelligente Kühlkanalführung 

Mit der Option DirectCool für das Programm der Hydrodehnspannfutter UNIQ bringt MAPAL eine zukunftsweisende Lösung auf den Markt, die die Kühlung und damit die Prozesssicherheit der Bearbeitung auf ein neues Niveau hebt.

Die Technologie geht auf die Anforderungen moderner Zerspanungsprozesse ein und zeichnet sich durch einfache Integration, hohe Wirtschaftlichkeit und technische Raffinesse aus.  

Die Hydrodehnspannfutter der UNIQ-Baureihe wurden von MAPAL 2020 eingeführt und seither kontinuierlich ausgebaut. Die UNIQ DReaM Chucks für Bohr- und Reibanwendungen und die UNIQ Mill Chucks für Fräsoperationen sind inzwischen bei einer großen Kundenbasis im Markt etabliert.

A key feature is being added to the UNIQ portfolio in 2025 in the form of the DirectCool option. DirectCool is a decentralised cooling system that enables precise cooling along the tool shaft to the cutting edge through three cooling channel bores. This allows the hydraulic chucks to achieve even temperature distribution, reduce wear and thermal distortion, significantly increase tool life, and enable consistent machining quality.

At the same time, the flushing effect improves process reliability and surface quality, as chips are removed effectively. DirectCool supplies reliable cooling and prevents tool breakage, particularly in boring processes where chips can wind around the tool. 

The UNIQ hydraulic chucks have unlimited compatibility. DirectCool integration does not alter tool restriction, so existing processes can be continued without adjustments. Cost-efficiency and flexibility are also assured, as no expensive shank grooves are required and standard tools and/or tools without internal cooling can be used.

UNIQ DirectCool is already producing promising results, particularly in stainless steel and aluminium machining. The technology will be officially presented at EMO 2025 in Hanover and represents a clear commitment to hydraulic clamping technology from MAPAL. For the market launch, DirectCool is optionally available for UNIQ Mill Chucks, HA and UNIQ DReaM Chucks with 4.5° outer geometry in diameters from 6 to 32 mm. 

Background: What sets the UNIQ hydraulic chucks apart

UNIQ hydraulic chucks have an identical outer geometry to the shrink chuck. At the same time, the hydraulic chuck can be distinguished externally from shrink chucks due to its glossy surface and blue screw in the HSK collar. UNIQ hydraulic chucks are highly durable and corrosion-resistant. MAPAL has picked up several design awards for the chuck.
