Clamping
Systems
Design:
Key-less and self-tightening precision design with safety guard.
High concentricity
(based on DIN ISO 10 888) for more precise bores and longer tool life.
All wear parts are case-hardened, ground and manufactured to be compatible with each
other as well as interchangeable.
Application:
For use on CNC machines and machining centres.
Note:
Due to the keyless lock on the set collar, the chuck‘s clamping force safety device
prevents slacking of tension on the chuck when there is abrupt machine speed reduction.
The function of the self-tightening stepless action nevertheless remains effective. That way
this Albrecht system maintains the maximum clamping force in each case.

High-performance quick-action chuck with secure mounting
Design:
Keyless and self-tightening
with mounting shank (one-piece).
Chuck and mounting shank form
one unit.
Optimal stability and higher concentricity is achieved by compact design
(based on DIN ISO 10888).
Application:
For high endurance stress as well as precision work on drills, drilling machines
and special drilling units.
Note:
The advantage over a two-part system is the length shorter by a total of 21 mm
and thus is advantageous for machines with a small working area.
Available with diamond-coated jaws on request.
