Combination milling arbor DIN 69871 AD/B, SK40, clamping Ø 22 mm — TECWERK

The Combination milling arbor is a SK40 toolholder designed to receive milling cutters with longitudinal or transverse keyways for secure, high‑precision machining in production and toolroom environments

• Steep taper DIN 69871 form AD/B
• Case‑hardened and ground finish
• Clamping diameter 22 mm for secure fit

Consistent accuracy and reduced setup time for milling operations

The taper connection to DIN 69871 and the SK40 shank ensure a rigid interface that minimises run‑out and maintains tool alignment during cutting. A precise taper seat concentrates clamping forces and reduces vibration, which in turn enhances tool life and process stability. The arbor’s geometry, including the 40 mm shank diameter, delivers a reliable transmission of torque; this reduces the need for repeated adjustments and shortens machine downtime, supporting efficient production workflows.

Secure mounting for cutters with longitudinal or transverse keyways

Designed specifically for the reception of milling cutters with longitudinal or transverse keyways, the arbor features a clamping diameter of 22 mm that provides a positive, backlash‑free fit. This configuration converts axial and tangential forces into the tool body reliably, avoiding slippage under load. For users less familiar with keyway‑mounted cutters, the principle is simple: the key engages the cutter slot so that rotational forces are taken by the key and the clamping system, improving repeatability and enabling consistent surface finishes.

Durable finish and compact dimensions for workshop robustness

The arbor is case‑hardened and ground, a combination that increases surface hardness where it matters while preserving accurate dimensions and a smooth mating surface. The hardened outer layer resists wear from repeated mounting cycles; the ground finish maintains the seating geometry for long‑term precision. With an overall A dimension of 55 mm and a face length of 19 mm, the component is compact yet sufficiently robust for routine milling tasks, offering a practical balance between accessibility to cutters and mechanical stability.

FAQ

Which spindles is this arbor compatible with?
The TECWERK combination milling arbor is designed for SK40 interfaces and conforms to DIN 69871 form AD/B, making it suitable for machines and spindle systems that accept that taper standard.

Can it be used with cutters that have a transverse keyway?
Yes, the arbor accepts milling cutters with either longitudinal or transverse keyways, so cutters secured by a key are fully supported by the clamping arrangement.

What are the key dimensional values to check before ordering?
Important dimensions are the shank diameter (40 mm), the clamping diameter (22 mm), A = 55 mm and L = 19 mm; these values determine fit and suitability for a given tool and machine configuration.

How does the case‑hardening and ground finish affect performance?
The case‑hardened and ground surface increases wear resistance at the seating area while preserving the precise geometry required for accurate taper engagement and long‑term repeatability.
