MAPAL has introduced the DirectCool option for its UNIQ hydraulic chuck range, presenting a next-generation solution designed to enhance cooling efficiency and improve machining process reliability. The new technology meets the demands of modern machining and is engineered to be cost-effective, technically advanced, and easy to integrate into existing setups.
The UNIQ range of hydraulic chucks, first launched in 2020, has continued to grow steadily. The portfolio now includes the UNIQ DReaM Chucks for boring and reaming applications and the UNIQ Mill Chucks for milling operations, both of which have established a solid market presence and a wide customer base.
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.
