Description

Product Overview

Special collets for micro parts are custom-manufactured precision gripping devices designed for Swiss-type CNC lathes processing extremely small-diameter workpieces (typically under 5mm). Standard collet tolerances are often insufficient for high-precision micro-part production — these special collets offer bores ground to ±0.002mm or tighter, custom internal profiles for non-circular stock, and specialized gripping surfaces for delicate medical, watchmaking, and electronic components.

Technical Specifications

• Application: Swiss-type CNC lathe main and sub-spindle clamping
• Bore range: Typically 0.5mm to 5mm diameter
• Bore tolerance: ±0.002mm or better

Applications & Industries

• Dental implant micro-component gripping
• Watchmaking pivot and staff turning
• Medical suture needle manufacturing
• Electronic connector pin machining
• Aerospace micro-fastener production

Features & Benefits

• Ultra-tight tolerances: superior part concentricity and roundness
• Custom bore profiles: grip non-round or pre-formed workpieces
• Minimizes part damage: optimized clamping pressure for delicate materials
• Direct replacement: available for all major Swiss-type machine makes
• Custom collets typically available in 2–4 weeks
