UNIQ DIRECTCOOL:DECENTRALISED COOLING FOR MAXIMUM EFFECT
Smart cooling channel guidance: A new feature for MAPAL’s UNIQ hydraulic chuck
With the DirectCool option for the UNIQ hydraulic chuck range, MAPAL launched a future-forward solution that takes cooling and the process reliability of machining to a new level. The technology addresses the requirements of modern machining processes and is cost-effective, technically refined and easy to integrate. key factor in the era of unmanned shifts, robot-assisted machining and growing complexity in component manufacturing.
The UNIQ range of hydraulic chucks was introduced by MAPAL in 2020 and continually expanded ever since. The UNIQ DReaM Chucks for boring and reaming applications and UNIQ Mill Chucks for milling operations are established on the market with a large customer base.
A key feature was added to the UNIQ portfolio 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 was 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.
With its smart cooling channel guidance, UNIQ DirectCool is initially available for UNIQ Mill Chucks HA and UNIQ DReaM Chucks with 4.5° geometry in diameters from 6 to 32 mm from autumn 2025.
Dear business partners,
dear readers,
at MAPAL, we see changes as responses to the needs of our markets and our customers rather than as an end in themselves. That is why our goal, that we actively pursue with every change, is clear: We are creating the conditions to get even closer to your needs and provide you with even more targeted support.
Our new organisation and legal structure in Germany is a vital step in this direction. Merging our German locations helps us operate in a way that is quicker, more efficient, and above all, more customer-oriented. We have been following this path consistently for some years now. Testament to this is the further development of our Global Organization for Assembly (GOA), which is now even more closely intertwined with our global aerospace clients than ever.
The GOA also underlines the great importance of aerospace for the MAPAL Group. Even if the market requirements and procedures of the aerospace industry in part vary to a great extent from the automotive industry, we are consciously drawing on a tried-and-tested principle: We are developing a deep and detailed understanding of applications, processes and you, our customers, we develop perfectly tailored solutions and closely assist you with during implementation. Taking this holistic approach for us is crucial for success.
We are also continually developing our portfolio. In addition to innovative tools – some of which we present to you in this edition of IMPULSE – we have taken our service portfolio to a whole new level, now offering comprehensive turnkey solutions. What does this mean for you? We take full responsibility for planning, implementing and optimising your manufacturing projects, guaranteeing quality, cycle time and costs. This is how we create efficiency and quantifiable added value.
All these changes share a common goal: to strengthen the foundation for successful dialogue and trust-based cooperation. After all, innovation thrives on collaboration.
In this spirit, we look forward to the opportunity for further dialogue at trade shows, events, or on your premises. Let’s move things forward together.
Yours,
Dr. Jochen Kress
