Synchronised Tapping Chuck TW (DIN 1835 B+E) – Weldon shank, coolant feed (TECWERK)

The Synchronised Tapping Chuck TW is a purpose-built tapping chuck for CNC machines with synchronised thread-cutting spindles, designed to compensate for pitch deviations and to handle both right‑ and left‑hand threads.

• Weldon shank DIN 1835 B+E
• Integrated coolant feed
• Axial compensation ±0.5 mm
• Suitable for right- and left-hand threads

Accurate synchronised threading for repeatable results

The TW chuck offers axial compensation of ±0.5 mm to absorb small pitch mismatches between the tap and the synchronised spindle; this prevents thread distortion and reduces scrap rates. Thanks to its high runout accuracy, the system maintains concentricity during tapping cycles, which translates into consistent thread profiles and fewer reworks. For production environments where repeatability and reduced inspection effort are priorities, the chuck’s tolerance for minor synchronisation errors improves overall process stability and product conformity.

Built for CNC integration and reliable coolant management

Equipped with a Weldon shank to DIN 1835 B+E and an integrated coolant feed, the chuck is intended for straightforward installation on CNC machines fitted with synchronised thread‑cutting devices. The coolant supply supports internal lubrication for cutting tools, improving chip evacuation and tool life during through‑coolant tapping. Compatibility with both right‑ and left‑hand threads increases the chuck’s versatility across batches and part families, allowing single‑setup operations where reversal of thread hand is required.

Robust clamping that reduces setup time and downtime

High clamping force is achieved by tensioning in tap collets with an integrated square drive, providing secure engagement and reliable torque transfer during tapping operations. Secure clamping minimises slippage and wear on the tap shank, helping to extend tool life and reduce unplanned stoppages. Built for industrial use, the chuck supports continuous production demands while simplifying changeovers: the combination of stable grip and synchronised compensation contributes directly to reduced downtime and more predictable cycle times.

FAQ

What does axial compensation of ±0.5 mm mean for threading performance?
Axial compensation allows the chuck to absorb small pitch differences between the tap and the synchronised spindle, preventing overstress on the tap and reducing the risk of distorted threads when using the synchronised tapping chuck TW.

Can left‑hand threads be produced with this chuck?
Yes, the TW supports both right‑ and left‑hand threads, enabling flexible production without the need for additional tooling changes.

Is coolant supplied through the chuck?
The chuck includes an integrated coolant feed, permitting internal coolant supply to the tool for improved lubrication, chip control and extended tool life during tapping operations.

Which shank standard is used and is it suitable for CNC synchronised spindles?
The chuck uses a Weldon shank to DIN 1835 B+E and is specifically designed for use on CNC machines equipped with a synchronised thread‑cutting spindle.

How does the chuck ensure secure clamping and torque transfer?
Secure clamping is achieved via tensioning in tap collets combined with an integrated square drive, providing high clamping force, reliable torque transmission and reduced slippage during tapping cycles.
