high-accuracyhigh-speedhigh-precision

Overview
Pull-back collet chuck with compact body for secure, concentric clamping and fast collet changes.

Key features

• Gripping range: 4 - 65 mm (alternate listed: 4 - 52 mm)
• Collet increment: 1 mm
• Sleeve stroke: 4.5 mm
• Mount: A5
• Maximum speed: 6500 min-1
• Max input force: 45 kN (alternate listing: 40 kN)
• Max gripping force: 105 kN (alternate listing: 94 kN)
• Matching cylinders: S1552, SS1452K, SR1453

Product details

• Ultra-fast collet changes: typical change time 10 seconds to minimise cycle downtime.
• First-operation capability: accepts collets with ±0.5 mm range for handling rough/unfinished bar prior to high-accuracy second operation.
• Pull-back action: collet is pulled into the chuck to close and pushed out to open; back stops are not available — use where precise axial positioning is not critical.
• Installation: supplied with mounting bolts and a custom-machined drawtube connector for immediate fitting.
• Mounting options: direct mount to spindle or via precision adaptor plate to ensure repeatable installation and reduced adjustment.
• Construction: case-hardened components for rigidity and long service life.
• Compact body / wide range: DC Varibore collets enable a short body while covering wide capacities (series: 4–80 mm).
• Low profile: reduced nose diameter for improved tool clearance.
• Sealing: O-ring seals prevent coolant and chip ingress; no grease required for operation.
• High-speed suitable: direct-mount design delivers high concentricity for higher-speed operations not appropriate for conventional 3-jaw chucks.
• Collet compatibility: DC-52 Varibore collets (available smooth or serrated; serrated recommended for aggressive first-operation gripping).
