UNIQ - New generation of clamping chucks
UNIQ Mill Chuck & UNIQ DReaM Chuck, 4.5° receive Design Award
Both hydraulic expansion chuck series - UNIQ Mill Chuck and UNIQ DReaM Chuck - clearly combine the performance promise of quality and function in their new design. This is achieved through an optimal interplay of geometric and functional properties.
Function meets design – Industrial design with added value
The newly-developed hydraulic clamping system enables high machining parameters through excellent stability and accuracy. It minimises self-excited vibration so that clamped tools are not exposed to micro-vibration. This in turn leads to a reduced spindle load of up to 15 percent, enables a significantly longer tool life and guarantees optimal surface quality.
In addition, the brilliant surface which MAPAL creates using a specially developed polishing process ensures that the chucks are more resistant to dirt and corrosion. Users can safely clamp the tool in the holder with little force requirement. This is ensured by “foolproof handling”, i.e. simple and self-explanatory handling of the chucks. This saves a considerable amount of time compared to other clamping mechanisms, especially with the UNIQ DReaM Chuck, 4.5°.

With DirectCool, a configuration option is available to ensure optimal cooling even for tools without internal cooling. The decentralized DirectCool technology supports thermal stability during machining and contributes to consistently high precision and extended tool life, further enhancing process reliability.

Hydro clamping chuck - UNIQ Mill Chuck
Reliable. Dynamic. Agile.
The hydraulic UNIQ Mill Chuck is specially designed for clamping milling tools with an HA shank. Due to the high temperature resistance of 80 °C even with very long milling cycles, it impresses with highly dynamic milling applications such as SPM (Structural Part Machining), HSC (High Speed Cutting) or HPC (High Performance Cutting) of high-quality components with excellent process reliability and a high material removal rate. Universal application for roughing, semi-finished and finishing operations.
Top 3 Features
- High thermal stability of 80 °C even with very long milling cycles (over 240 minutes)
- For high-performance milling operations up to max. 33,000 revolutions per minute
- Maximum process reliability and tool life due to award-winning industrial design
At a glance
- Hydraulic chuck for highly-dynamic milling applications
- Optimal interplay of geometric and functional properties
- Excellent results when using tools with HA shanks
- Highest process reliability even with high-quality parts
Hydro clamping chuck - UNIQ DReaM Chuck, 4.5°
Visionary. Flexible. Economical.
The UNIQ DReaM Chuck, 4.5° is ideally suited for reaming and drilling applications as well as for use with finishing milling cutters. Thanks to the clamping initiation in the hollow shank taper flange, it enables maximum rigidity with minimal use of material at minimal tool restriction. The outer contour of the UNIQ DReaM Chuck is based one to one on DIN 69882-8 for heat shrink chucks. This means that the advantages of hydraulic expansion technology can be transferred to these applications.
Top 3 Features
- Hydraulic chuck with the original dimensions of a shrink chuck (DIN contour with 4.5°)
- Application-oriented system design
- Maximum process reliability and tool life due to award-winning industrial design
At a glance
- For reaming and drilling applications as well as for finishing during milling operations
- Optimal interplay of geometric and functional properties
- Outstanding surfaces with improved handling at the same time
- Maximum flexibility and productivity when machining contour-critical parts
- Designed to meet the requirements of a wide range of markets such as the die and mould sector, aerospace and the automotive sector
