TECWERK synchronised tapping chuck DIN 69893 Form A, HSK‑A63 – for M3–M27

The TECWERK synchronised tapping chuck for high-precision CNC tapping, designed to compensate pitch differences and provide through-spindle coolant for production environments

• Hollow shank taper DIN 69893 A
• Integrated coolant supply
• Compensates pitch differences ±0.5 mm
• Suitable for M3–M27 synchronised tapping
• High runout accuracy and strong clamping

Precision where synchronisation matters

The synchronised tapping chuck is engineered for consistent thread creation on machines with a synchronised tapping drive. Fitting the HSK‑A63 interface and specified for M3–M27, the unit maintains synchronisation between spindle and tap, reducing thread rejects. The design follows DIN 69893 Form A, a recognised standard for hollow‑shank interfaces, enabling straightforward machine integration and repeatable positioning for automated cycles while supporting both right‑ and left‑hand threads.

Built to manage pitch deviations and coolant needs

A central benefit is the chuck’s capacity to compensate pitch differences and absorb minor synchronisation shifts: a mechanical length compensation of ±0.5 mm limits stress on taps during engage and retract phases. The hollow shank taper permits through‑spindle coolant supply, maintaining lubrication and chip evacuation right at the cutting edge. Together these features extend tool life and preserve component tolerances; runout control contributes directly to consistent thread form and surface finish.

Production advantages for CNC workshops

For CNC workshops and contract manufacturers, the unit offers measurable process benefits: fewer scrap threads, reduced spindle load spikes and lower rework rates. The high clamping force delivered via tap collets with integrated square keeps taps secure during torque reversals, while the compact envelope supports tight tool‑path planning. The result is improved throughput and predictable cycle times, which aid capacity planning and customer delivery commitments.

Easy fit, compact footprint, and robust construction

With an overall outer diameter of Ø 50 mm and a functional length A: 108 mm, the chuck presents a compact, rigid interface to synchronised tapping spindles. The construction balances stiffness with the necessary axial compliance to protect taps under overload conditions. In production use the TECWERK synchronised tapping chuck integrates with standard toolholders, requires routine inspection rather than complex maintenance, and is suitable for continuous operation on CNC machines equipped with synchronised tapping devices.
