FK-08 | 8 in Finger / Face-Clamping Chuck
The TOP-TOOL FK-08 is a 8 in finger / face-clamping chuck for CNC lathe applications. The finger-type clamping elements contact the end face or limited clamping areas, helping keep more of the outside diameter accessible for machining.
This finger / face-clamping chuck is used when the workpiece cannot be held deeply from the outside diameter. It is suitable for thin rings, short workpieces, disc-type parts and components where outside-diameter gripping would interfere with machining.
Key Features
- Face-clamping structure holds the workpiece from the end face or a limited contact area.
- Finger-type clamping elements are useful when conventional jaw contact is not suitable.
- Leaves more outside surface available for machining.
- Suitable for thin rings, short blanks and disc-type workpieces.
- Designed for specific CNC lathe clamping problems rather than general jaw chuck use.
Typical Applications
- Thin ring parts
- Short workpieces
- Disc-type components
- Workpieces with outside-diameter machining interference
- Parts requiring end-face clamping
Selection Notes
- Confirm whether the part can be clamped from the end face.
- Check the available clamping area, wall thickness and part rigidity.
- Review whether outside-diameter clamping interferes with machining.
- Confirm clamping force, finger stroke and locating method.
- For thin-wall parts, review deformation risk before ordering.
