Transverse-slot mounting arbor HSK-A63, clamping Ø16 mm – TECWERK

The transverse-slot mounting arbor by TECWERK is a DIN 69893 Form A tool holder for secure attachment of cutter heads and milling cutters with a transverse slot, designed for precision slot milling applications.

• Enlarged collar for higher rigidity
• Hollow shank taper to DIN 69893 Form A
• Face coolant bores for directed coolant flow
• For cutter heads and cutters with transverse slot

Improved rigidity for reproducible slot precision

The arbor delivers a stable connection between machine spindle and tooling thanks to its enlarged collar diameter and HSK interface. Increased collar mass reduces deflection under cutting loads, which directly improves dimensional accuracy and surface finish when producing transverse slots. This stability is particularly beneficial in high-precision milling setups, where tool bending can cause tolerance drift; the design helps to maintain repeatability across batches while reducing rework and scrap.

Effective coolant routing to protect cutting edges

Integrated coolant channel bores at the face provide a direct path for lubrication and cooling to the cutter interface, aiding heat control and chip evacuation. By directing coolant to the cutting zone, the arbor helps to extend tool life and maintain cutting performance during longer cycles. The combination of internal coolant routing and a hollow shank taper supports consistent thermal conditions at the tool holder, which contributes to steady machining results and fewer unplanned tool changes.

Conformity with standards and broad tool compatibility

Manufactured to DIN 69893 Form A, the arbor mates with HSK-A63 spindles and accepts cutter heads and milling cutters with a transverse slot to DIN 1880. The clear specification of the shank geometry and mounting interface simplifies tool selection and setup in CNC environments, enabling predictable clamping behaviour and fast tool changes. This standard conformity reduces setup time and ensures interchangeability within established tooling systems.

Practical dimensions for workshop efficiency

Key dimensions are optimised for common slot-milling tasks: a nominal diameter of 38 mm, a clamping diameter of 16 mm and a functional projection length of 50 mm with a 17 mm segment relevant for the mounted tool. These measures support a compact yet robust tool assembly that balances reach and stiffness, making the arbor suitable for repetitive production runs where consistent performance and straightforward inspection are required.

FAQ

What spindle interface does this arbor use?
The arbor uses an HSK-A63 interface in accordance with DIN 69893 Form A, ensuring secure clamping and fast tool changes.

Which cutter types can be mounted on this arbor?
Cutter heads and milling cutters designed for a transverse slot to DIN 1880 can be mounted on the TECWERK transverse-slot mounting arbor.

How does the coolant supply work on this arbor?
Coolant is supplied via face bores that direct lubricant to the cutter interface, supporting chip evacuation and temperature control.

Will the enlarged collar improve machining stability?
Yes, the enlarged collar diameter increases rigidity at the tool holder junction, reducing deflection and improving repeatability during slot milling.
