27026 THREE-JAW SELF-CENTERING CHUCK FOR DB 250 LATHE PROXXON

Efficiency and Precision in Circular Tightening

The Proxxon chuck code 27 026 represents a fundamental technical extension for the DB 250 micro lathe. Unlike independent jaw systems, its self-centering function allows the workpieces to be clamped in a single operation, ensuring that the material is perfectly aligned with the crankshaft in just a few seconds.

Technical and Construction Features:

• High Quality Material: The accessory is constructed of solid die-cast steel , a material chosen to ensure mechanical stability and wear resistance during turning sessions.
• Clamping Mechanism: Three synchronized jaw system that move simultaneously for automatic centering of the workpiece.
• Reversible Jaws: The design features jaws that can be removed and fitted the other way around, allowing you to quickly switch between internal and external grip configurations.
• Easy Installation: Equipped with an M 16 x 1 threaded connection , the spindle screws directly and securely onto the crankshaft of the DB 250 without the need for complex adapters.

Operating clamping capabilities:

• Grip with jaws in standard position (Internal Clamping): allows you to clamp pieces with a diameter from 1.5 to 20 mm .
• Socket with inverted jaws (External Clamping): allows you to accommodate pieces with a diameter from 12 to 50 mm .

This mandrel is the ideal tool for the mass production of small cylindrical components such as plates, cups and vases for dollhouses, or for the production of poles and tanks in model railways.

Technical note: Although the chucks offer great convenience in quick changes, for jobs requiring maximum absolute concentricity and superior clamping force, Proxxon sources suggest integration with MICROMOT steel collets.
