Face clamping chuck DIN 69893A, Weldon, 10 mm clamping Ø, HSK‑A63 — TECWERK

The face clamping chuck DIN 69893A (Weldon) HSK‑A63 is a toolholder designed to securely clamp cylindrical‑shank cutters with lateral drive surfaces in HSK‑A toolholders, suitable for precision machining and retrofit on HSK‑A63 spindles.

• HSK‑A63 interface for secure tool holding
• Weldon flat for lateral drive per DIN 1835‑B
• 10 mm clamping diameter with H4 bore tolerance
• Compact 35 mm body, A length 65 mm

Improved machining reliability through optimised retention and interface design

The compact face clamping chuck combines the short taper of the HSK‑A63 interface with a Weldon flat to ensure positive torque transmission and minimal slip during heavy cuts. Compared with conventional taper‑only holders, the lateral drive surface secures tools with a DIN 1835‑B clamping profile, reducing micro‑movement and improving tool life. The result is consistent component quality, fewer rework cycles and a measurable reduction in downtime for critical production runs.

Faster set‑up and consistent concentricity thanks to precision bore tolerance

A bore manufactured to H4 tolerance and a nominal clamping diameter of 10 mm support tight concentricity and repeatable seating of cylindrical shanks. The compact body (Ø 35 mm) and A length 65 mm allow straightforward insertion into standard HSK‑A63 toolholders, shortening changeover time and enabling predictable spindle dynamics. This precision reduces the need for constant re‑measuring and assists in maintaining cycle times across batch production.

Broad compatibility with standardised tooling for reduced inventory complexity

Designed to accept tools with a cylindrical shank and lateral engagement to DIN 1835‑B, the chuck offers straightforward compatibility with common cutter types used in milling and drilling operations. The Weldon configuration translates into simple mechanical engagement without custom adapters, helping to consolidate tooling stock while preserving machining flexibility. This compatibility supports lean workshop inventories and simplifies tool management strategies.

Robust design that supports predictable maintenance and integration

Built to the DIN 69893 Form A specification with a hollow shank taper, the chuck is intended for repeated mountings and operational cycles typical in production environments. The HSK‑A interface facilitates rapid automatic seating and removal, while the Weldon drive delivers secure mechanical indexing under load. Where process reliability and repeatability are priorities, this configuration reduces the variables that can affect machining tolerances and streamlines preventive maintenance planning.
