SK40 Milling Arbor, Milling Cutter Head Holder DIN 69871

The SK40 shell mill arbor according to DIN 69871 is the ideal solution for demanding milling applications in modern manufacturing. With an outstanding runout accuracy of ≤ 0.005 mm, this arbor guarantees highest precision and superior surface quality in machining.

Manufactured from high-quality 42CrMo, the arbor is characterized by its excellent strength and resilience. Through a special heat treatment process in which the arbor is hardened by quenching, it achieves a hardness of 52 HRC, which ensures a particularly long service life and reliable performance. These characteristics make it particularly suitable for use in demanding production environments, where high loads are common.

Its design according to the DIN 69871 standard ensures that it is compatible with a variety of CNC machines, making it a universal choice for a wide range of applications. Moreover, the high runout accuracy helps to minimize vibrations, which not only improves the quality of the machined parts but also extends the life of the tools. Practical examples from the industry show that users with this milling arbor were able to achieve significant productivity increases and cost savings.

The simple assembly and disassembly of the milling arbor enable a quick tool change, which further increases efficiency in manufacturing. Overall, the SK40 shell mill arbor sets new standards in terms of precision, durability, and versatility and is an indispensable tool for every professional in machining technology.

Aufsteckfräserdorn passt

Der Aufsteckfräserdorn saubere Aufnahme für meinen Eckfräser, Rundlauf wiederholgenau. Qualität gefällt. Werkzeug hat mir bei der Bearbeitung anspruchsvoller Werkstoffe wie 1.4571 und 42CrMo4 gute Dienste geleistet, die Werkzeugausführung bleibt stabil und die Werkzeugstandzeit konstant.

Aufsteckfräserdorn für Messerkopf

Der Dorn passt exakt, der Messerkopf läuft sauber rund. Verarbeitung und Spindelsitz wirken wertig. Hab den für verschiedene Werkstoffe genutzt und er läuft überall sauber, keine Ausfälle in Serie. Werde weitere Durchmesser der Reihe holen. Ich würde es ohne zu zögern wieder bestellen, die Qualität ist über dem Schnitt der Preisklasse.
