TECWERK Combination mounting arbor DIN 69871 AD/B – SK40, clamping Ø 27 mm

The combination mounting arbor is a compact mounting adapter for milling cutters with longitudinal or transverse key, designed for robust clamping in SK40 spindles and versatile machining tasks in production and workshop environments

• DIN 69871 Form AD/B compatibility
• SK40 taper shank for standard spindles
• Clamping diameter 27 mm for small cutters
• Case-hardened and ground for durability

High rigidity and dependable tool holding for consistent production

The steep taper specified in DIN 69871 and the SK40 shank give the arbor high axial and radial rigidity, which reduces runout and secures repeatable positioning of mounted cutters. This mechanical stability translates directly into more consistent surface finish and fewer rejects in batch production, as the solid interface between spindle and arbor dampens vibration and maintains concentricity under load. The design therefore supports productivity gains through reduced rework and stable machining results.

Surface hardening and precision grinding extend service life

Thanks to the case-hardened and ground treatment, the contact surfaces are wear-resistant while the core retains toughness, so the arbor withstands repeated mounting cycles and moderate shocks without premature fatigue. Precision grinding of the seating faces ensures low tolerance deviation and reliable centring of the toolholder, which helps to prolong cutter life and reduce maintenance intervals. The combination mounting arbor thus offers a balance of durability and precision that is advantageous for continuous workshop use.

Flexible compatibility for straightforward integration into machining cells

With a clamping diameter of 27 mm and an overall diameter of 48 mm, the adapter accepts milling cutters featuring longitudinal or transverse keyways, enabling quick adaptation to commonly used cutter designs. The projection dimension (A: 55 mm, L: 21 mm) provides sufficient clearance for a variety of setups while keeping overhang minimal to preserve stiffness. Compatibility with standardised interfaces makes this arbor a practical choice when integrating into existing SK40 tool chains or when standardisation across a fleet of machines is required.

FAQ

What spindle standard does this arbor follow?
The TECWERK combination mounting arbor is specified to DIN 69871 Form AD/B, making it compatible with spindles and interfaces designed to that standard.

Which cutters can be mounted on this arbor?
Milling cutters with either a longitudinal or transverse key can be mounted on the arbor thanks to the clamping diameter of 27 mm and the keyway-compatible design.

Is the arbor suitable for heavy-duty production use?
The case-hardened and ground finish plus the SK40 shank deliver the rigidity and wear resistance expected for regular workshop and light industrial production environments.

How does the arbor help with tool repeatability?
The steep taper and precision grinding of seating surfaces ensure low runout and consistent centring, so the TECWERK arbor maintains repeatable positioning across multiple tool changes.
