DA milling system

Product catalog summary

Overview: The document provides comprehensive specifications and guidelines for the new generation of milling tools, specifically the System DA and DAH. It covers spare parts, milling shanks, screws, and the use of TORX PLUS® wrenches, focusing on various milling operations like plunge milling and high feed milling with indexable inserts.

Specifications: It details part numbers, dimensions, and materials for components such as milling shanks and heads, recommending steel for shanks but advising against shrinking. Cutting edge diameters range from 10.4 mm to 40 mm, tailored to specific applications.

Procedures: The document provides detailed instructions for using milling tools, including recommended torque for screws and appropriate TORX PLUS® wrench sizes. It outlines procedures for plunge milling and chamfering at 45° angles.

Standards and Recommendations: It includes cutting data and formulas for calculating revolutions, cutting speed, feed per tooth, and material removal rate. Recommendations are given for different carbide grades, such as TA45 for easy-to-machine materials and SA4B for more challenging ones.

Key Data from Tables: Tables list part numbers, dimensions, and specifications for milling components, along with cutting data for various materials, specifying feed rates and cutting speeds for different hardness levels and material types.

Critical Information: Emphasizes selecting the correct carbide grade and cutting parameters based on the material. Highlights the potential to increase feed per tooth by a factor of 1.4 when milling at a 45° angle.

DAH37 Indexable Insert Overview: Provides technical specifications and guidelines for the DAH37 indexable insert in high feed milling applications, including formulas for calculating key parameters and recommended cutting data for various materials.

DAH37 Specifications: Designed for use with a milling head, allowing a depth of cut up to 1.2 mm. Includes formulas to calculate RPM, cutting speed, feed per tooth, feed rate, and material removal rate.

Formulas: Key formulas include:

n = (vc * 1000) / (deff * π) [RPM]
vc = (deff * π * n) / 1000 [m/min]
Q = (ae * ap * vf) / 1000 [cm³/min]
fz = vf / (Z * n) [mm]
vf = fz * Z * n [mm/min]

Where deff is the effective cutting diameter, Z is the number of teeth, and other variables are defined in the document.

Correction Values: A table provides correction values (KD) based on the depth of cut (ap) ranging from 0.1 mm to 1.2 mm, used to calculate the effective cutting diameter (deff).

Material Specifications: Lists recommended feed per tooth (fz) and cutting speed (vc) for various materials, including unalloyed and alloyed steels, stainless steels, cast irons, and aluminum alloys, with hardness values (HB) for each material type.

Diving Angles and Programming: Includes information on diving angles for different diameters, theoretical corner radius (rth), and maximum allowable deviation for programming purposes.

Cutting Data System DAH37: Provides specific cutting data for the DAH37 system to ensure optimal performance and efficiency in milling operations.
