MAPAL has introduced the DirectCool option for its UNIQ hydraulic chuck range, adding decentralised cooling to improve process reliability in machining applications. The development responds to increasing demands for thermal stability and consistent performance in modern production.

MAPAL launched the UNIQ hydraulic chuck series in 2020 and has since expanded the portfolio to include UNIQ DReaM chucks for boring and reaming, and UNIQ Mill chucks for milling. The new DirectCool feature extends the capability of both systems.

DirectCool guides coolant along the tool shaft to the cutting edge through three internal channels. This targeted supply supports even temperature distribution, reduces thermal distortion and limits wear. It also improves chip evacuation, particularly in boring operations where chips can wrap around the tool. By stabilising the process at the cutting zone, the system helps maintain surface quality and reduce the risk of tool breakage.

The integration of DirectCool does not alter the external geometry or restrict tool selection. Users can continue to run existing tools, including those that lack internal cooling, without modifying established processes. The system does not require special shank grooves. MAPAL first presented DirectCool to the public at the last EMO exhibition in Hannover, Germany.

The option is available for UNIQ Mill chucks and HA and UNIQ DReaM chucks with 4.5° outer geometry in diameters from 6 to 32 mm. UNIQ hydraulic chucks share the same outer geometry as shrink chucks but feature a glossy surface and blue screw in the HSK collar for identification.
