Frequently Asked Questions
When to use this chuck?
It is a self-centering chuck for clamping workpieces on a lathe during turning operations.
Self-centering chucks allow for quick clamping of the workpiece with a single key. The choice depends on the shape of the workpiece (cylindrical, square) and the body material (steel or cast iron).
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.
For which workpieces is the Ø 140 mm diameter suitable?
Suitable for small to medium workpieces (max Ø ~140 mm): bench lathes and artisan workshops.
The nominal diameter of the chuck indicates the maximum size of the body, not the machinable workpiece. The clamping capacity depends on the jaw opening (typically 60-70% of the nominal Ø).
How do I check compatibility with my lathe?
Check the type of mounting on the lathe spindle nose (Camlock D3-D15, or threaded mount M-) 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 rectified bar and measuring with a dial indicator: acceptable tolerance 0.03-0.1 mm depending on the model.
