Flächenspannfutter DIN 69893A Weldon Spann‑D.8mm HSK‑A63 A.‑L.100mm TECWERK — Face clamping holder with Weldon lateral drive and 100 mm projection

Flächenspannfutter DIN 69893A Weldon Spann‑D.8mm HSK‑A63 A.‑L.100mm TECWERK is a face clamping holder designed for machining centres with HSK‑A tool interfaces; it clamps cylindrical tool shanks with a Weldon flat according to DIN 1835‑B for reliable torque transmission.

• HSK‑A63 taper interface for fast tool changes
• 100 mm projection length for extended reach
• 8 mm clamping diameter for Weldon‑flat tools
• Bore tolerance H4 for repeatable concentricity

Precision clamping that reduces setup variation

The holder delivers consistent axial and radial alignment thanks to the DIN 69893 Form A hollow shank taper and the specified H4 bore tolerance. This precision interface reduces runout and ensures that the cutter sits true in the spindle, so machining programmes run reliably from the first part. For production environments, that stability translates directly into fewer rejected parts, longer tool life and less time spent on inspection — an efficiency gain rather than a mere feature.

Secure torque transfer for demanding milling operations

Equipped with a Weldon lateral drive and a defined 8 mm clamping diameter, the arbor provides positive drive for tools with a cylindrical shank and the lateral flat per DIN 1835‑B. The result is secure torque transmission under heavy side loads, which is crucial for slotting, shoulder milling and interrupted cuts. Where controlled power transfer and minimal slipping are priorities, this holder minimises the risk of tool rotation inside the chuck and supports repeatable cycle times.

Reach and rigidity balanced for workshop flexibility

With a 100 mm projection length the holder offers extended reach while retaining adequate stiffness for many common milling tasks. The hollow shank taper HSK‑A63 ensures rapid engagement with the machine spindle, reducing changeover times and supporting consistent contact on the clamping face. This balance of reach and rigidity suits job shops and production lines that require flexibility without sacrificing component accuracy.

Practical integration and workshop advantages

The face clamping design is compatible with cylindrical shank cutters fitted with a Weldon flat, enabling straightforward retrofitting on HSK‑A machines. The DIN 69893 standardisation simplifies procurement and ensures interchangeability across machines that support the same interface. For production planners this means predictable machine behaviour, easier spare‑parts handling and reduced logistical complexity when replacing holders.

FAQ

What tool shank types does this holder accept?
The TECWERK face clamping holder accepts cylindrical shanks with a Weldon lateral flat according to DIN 1835‑B; the clamping diameter is 8 mm.

Is the holder compatible with HSK‑A63 spindles?
Yes — the arbor uses the HSK‑A interface (DIN 69893 Form A), designed specifically for HSK‑A63 machine spindles.

How does the H4 bore tolerance benefit machining accuracy?
An H4 bore tolerance provides a tight, repeatable fit that minimises runout and contributes to consistent part quality when using this clamping arbor.

Does the 100 mm projection affect rigidity significantly?
The 100 mm projection increases reach while maintaining suitable stiffness for many milling operations; however, for heavy interrupted cuts a shorter projection may improve rigidity.

Can the holder transmit high torque for heavy milling?
Yes — the Weldon lateral drive combined with the HSK‑A63 interface ensures secure torque transmission for demanding milling applications.
