System DAH25

Product catalog summary

Introduction
This document introduces the DAH25 system by HORN, a leader in grooving technology, focusing on high feed milling with high cutting performance. The system is designed to enhance existing DAH systems by accommodating smaller diameter ranges.

Specifications
The DAH25 system includes four end mills with Weldon toolholders, offering cutting edge diameters of 12, 16, 20, and 25 mm. These are equipped with two to four indexable inserts. The holders feature internal cooling and a TiN coating for corrosion and chip impact protection. The indexable inserts have two cutting edges, secured by a screw, with precision-sintered chip surface geometry and a large cutting radius for smooth cuts. The maximum cutting depth is 1.0 mm, with a cutting edge corner radius of 0.4 mm. Optimal feed rates per tooth range from 0.5 to 2.5 mm, with cutting speeds (vc) between 180 and 260 m/min.

Materials and Applications
The system is suitable for milling various materials, including steel, stainless steel, cast iron, aluminum, and titanium. The tough substrate SA4B is highlighted for its success in high feed milling.

Spare Parts and Tools
Spare parts include the milling shank, screws, and TORX PLUS® wrenches. Specific part numbers and dimensions are provided for ordering.

Formulas and Cutting Data
Formulas for calculating effective cutting diameter, revolutions, cutting speed, material removal rate, and feed rate are provided. The document includes a correction value chart and detailed cutting data for various materials, specifying hardness, feed per tooth, and cutting speed.

Contact Information
Contact details for HORN's offices in Germany, the UK, France, the USA, Hungary, and China are provided for further inquiries.

System DAH25 Hochvorschubfräsen mit hoher Schnittleistung Ein neues Werkzeugsystem zum Hochvorschubfräsen ergänzt die bisherigen DAH-Systeme um kleinere Durchmesserbereiche. Vier Schaftfräser mit Weldonaufnahme ergänzen das System DAH mit Schneidkreisdurchmessern von 12, 16, 20 und 25 mm nach unten. Sie sind mit zwei bis vier Wendeschneidplatten bestückt. Alle Halter sind mit Innenkühlung ausgelegt und gegen Korrosion und Späneschlag TiN-beschichtet. Die neu entwickelten Wendeschneidplatten mit je zwei Schneiden werden mittels einer Schraube sicher gespannt. Die speziell präzisionsgesinterte...
