Frequently Asked Questions
What is the FLD 630 - D15 spindle flange used for?
It is a flange for mounting a chuck on metal lathes, with a diameter of Ø 630 mm and a D15 coupling.
It allows for secure attachment of the chuck to the lathe spindle nose according to FLD standards (DIN 55027 central pull stud coupling). The Ø 630 mm diameter corresponds to the nominal diameter of the compatible chuck.
What is the difference between FL and FLD series?
The FL (Ø flanges) has an external coupling according to DIN 55029. The FLD has a central pull stud coupling according to DIN 55027 (quicker to disassemble).
This model is FLD: for maximum compatibility with the lathe, check the standard of the chuck nose. Most professional Bernardo metal lathes use the FLD attachment.
What does the D15 coupling indicate?
The D15 (Camlock) code indicates the quick-release system: the number (e.g., D3, D4, D5, D6, D8, D11, D15) identifies the standard size of the coupling.
For correct compatibility, check the coupling of your lathe: D3-D5 for small/medium lathes, D6-D8 for medium-large lathes, D11-D15 for heavy industrial lathes.
Is it an original Bernardo spare part?
Yes, Krollit has been an official Bernardo distributor since 2007 and exclusively supplies original flanges for Bernardo lathes and DIN-compatible flanges.
Original flanges comply with the machining tolerances required by the DIN standard to ensure concentricity and balance of the chuck. Do not use non-original flanges for precision machining.
How is the flange mounted on the lathe?
Mounting requires disassembling the existing chuck, thoroughly cleaning the lathe spindle nose, applying a light coat of oil, and tightening with the torque indicated in the manual.
For lathes with a Camlock system (DLD), the cams should be closed by hand up to the reference (usually a notch or line); do not force with tools. Krollit provides technical documentation and telephone support for mounting.
