- Application: suitable for miniature CNC machine tools, small milling machines, and related accessories. - Range and design: self-centring lathe chuck with extended clamping range, featuring inner and outer jaws for versatile gripping of small cylindrical workpieces. - Benefits and performance: a key clamping mechanism provides additional clamping force on the workpiece, improving grip, stability, and concentricity during machining. - Assembly and maintenance: degrease the tapped holes before assembly to ensure secure mounting and prevent thread damage. - Use scenarios: - Secure small-diameter shafts or pins during micro-lathe turning or precision milling. - Clamp model or prototype parts for accurate milling, drilling, or finishing. - Hold delicate components such as jewelry parts where tight, concentric clamping is needed.
