Frequently asked questions
What type of mounting does the Fresa collet chuck set ER 16 use?
Check the indicated attachment in the title or specifications (typically A2-5, A2-6, A2-8 according to DIN 55029).
The A2 flange attachment is standard for Bernardo Profi and Hobby range lathes. The number (5, 6, 8) indicates the flange size, which must match the lathe's headstock.
How many jaws does it have and are they reversible?
Standard self-centering chucks have 3 jaws; typically supplied with 1 set of internal and 1 set of external reversible jaws plus a tightening wrench.
3-jaw chucks are suitable for round or hexagonal workpieces. For square or irregular workpieces, consider independent 4-jaw chucks. Soft jaws can be machined on the lathe for special applications.
What is the maximum rotation speed?
See "Max speed" in the technical table: typically 2,500-3,500 rpm for chucks up to Ø 200 mm.
The maximum speed decreases with diameter. Large chucks (Ø 400+ mm) typically have limits of 1,500-2,000 rpm. Exceeding the maximum speed risks jaw detachment.
What concentricity precision does it offer?
Professional Bernardo chucks comply with DIN 8386 class with typical concentricity of 0.03-0.04 mm.
Concentricity is critical for precision finishes. For high-precision machining (microns), higher-class chucks or dedicated clamping collets are required.
How is it mounted on the lathe?
The chuck mounts directly onto the headstock flange via a camlock attachment for A2 systems.
The Camlock system allows quick mounting without an additional adapter flange. For lathes with a threaded attachment, a dedicated adapter flange is required. Krollit supplies compatible flanges separately.
