22mm Thread Cutting Synchronised Chuck With Coolant Feed, 0.5mm Axial Compensation, DIN 69893 Form A - TECWERK

Benefit from the combination of HSK‑A63 compatibility, ±0.5 mm axial compensation and integrated coolant feed for reliable synchronised tapping on CNC machines; order the synchronised tapping chuck directly via Metav Werkzeuge or consult the specialists for application advice.

Synchronised Thread‑Cutting Chuck HSK‑A63 – TECWERK (M3–M12, A=93 mm)

The synchronised tapping chuck (DIN 69893 A) by TECWERK is a precision accessory for CNC machines with synchronised tapping spindles, designed for reliable thread cutting across small metric sizes.

• HSK‑A63 interface, DIN 69893 A
• Suitable for M3–M12 threads
• Internal coolant supply for chip control
• Axial compensation ±0.5 mm

Accurate synchronization reduces rejected parts and rework

The synchronised tapping chuck delivers controlled axial compensation, specified as ±0.5 mm, to absorb small pitch mismatches between the tap and the synchronised spindle. This compensation reduces stress on the tap and the spindle drive, decreasing the risk of broken taps and dropped threads. The result is fewer rejected parts, improved first‑pass yield and more predictable cycle times on high‑mix CNC production runs.

Compact HSK‑A63 design improves spindle compatibility and rigidity

Built to DIN 69893 A with an HSK‑A63 mounting, the chuck offers the mechanical stiffness expected from HSK interfaces while maintaining compact dimensions (A = 93 mm, outside Ø 22 mm). The short, rigid design reduces overhang and vibration, which directly contributes to high runout accuracy and consistent thread quality. For workshops upgrading to synchronised tapping, the interface simplifies retrofit and tool change procedures.

Integrated coolant feed and secure clamping for process reliability

An internal coolant channel enables directed lubrication and chip evacuation at the cutting zone, supporting longer tap life and cleaner thread forms. The chuck achieves high clamping force through a tensioned tap collet with an integrated square drive, ensuring secure holding for both right‑ and left‑hand threads. These features together lower maintenance frequency and support uninterrupted production cycles.

Suitable thread range and operational versatility

Designed for metric threads from M3 to M12, the chuck covers the small to medium sizes commonly used in component manufacturing and assembly parts. Compatibility with right and left‑hand tapping broadens application scope. The combination of precise axial compensation, coolant supply and HSK mounting makes this accessory a pragmatic choice where synchronisation errors must be mitigated without adding complex electronics or external mechanisms.

FAQ

What spindle interface does the chuck use?
The synchronised tapping chuck is supplied with an HSK‑A63 interface conforming to DIN 69893 A, ensuring direct fit to compatible CNC spindle tap adaptors.

Which thread sizes are covered by this chuck?
The chuck supports metric thread tapping from M3 to M12, suitable for common small and medium machine components.

Can the chuck handle both right‑ and left‑hand tapping?
Yes, the design permits use for both right‑hand and left‑hand threads without modification, providing flexibility in mixed production environments.

How does the chuck manage pitch mismatch during synchronised tapping?
Axial compensation of ±0.5 mm allows the chuck to absorb small synchronisation errors in tension and compression, protecting taps and reducing broken‑tool incidents.

Is coolant supply integrated in the chuck?
An internal coolant feed is provided to lubricate the tap and assist chip evacuation, contributing to longer tool life and improved thread quality.
