Frequently asked questions
When to use a 4-jaw chuck?
Self-centering 4-jaw chucks are for square and 4-8 sided workpieces. The jaws move together with a single key.
The self-centering 4-jaw (not with independent jaws) clamps square or octagonal workpieces symmetrically. For off-center (eccentric, asymmetrical) clamping, independent jaw chucks are needed.
What material is the chuck body made of?
The material is indicated in the title: steel (PO series) for maximum precision, cast iron (DK/PS series) for standard use.
The choice depends on intensity of use and required tolerance: steel for production and precision, cast iron for general use.
Which diameter to choose?
The choice of diameter depends on the lathe spindle nose (it must match the mounting) and the size of the workpieces to be machined.
Typical diameters: 80-160 mm for hobby lathes, 200-315 mm for professional lathes, 400-630 mm for industrial lathes.
How do I check compatibility with my lathe?
Check the type of lathe spindle nose mounting (Camlock D3-D15, or threaded M- mount) and the corresponding diameter.
On modern lathes, Camlock mounting is the most common. On older lathes, there may be a threaded (M-) or flanged mount. The lathe's technical documentation indicates the exact type.
How is chuck precision maintained?
Regular cleaning of the spiral mechanism, periodic lubrication with specific chuck grease, concentricity check every 6 months with a dial indicator.
A jaw that moves with difficulty indicates chips or rust in the mechanism: disassemble, clean, and grease. Concentricity is checked by mounting a ground bar and measuring with a dial indicator: acceptable tolerance 0.03-0.1 mm depending on the model.
