"CVD" for milling non-ferrous materials

Product catalog summary

Overview: This document provides technical specifications and guidelines for using solid carbide end mills with CVD (Chemical Vapor Deposition) cutting edges, specifically designed for milling non-ferrous materials. It includes detailed parameters for various materials, tool dimensions, and recommended milling practices.

Specifications:

Materials and Cutting Parameters: The document lists various non-ferrous materials such as AlSi (aluminum-silicon alloys), glass ceramics, PMMA acrylic, and others, along with their respective cutting speeds (Vc), depth of cut (ap), width of cut (ae), and feed per tooth (fz). For example, AlSi with less than 12% Si has a cutting speed of 1800 m/min, while glass ceramics have a cutting speed of 250 m/min.
Tool Dimensions: The document provides detailed dimensions for ball nose end mills and corner radius end mills, including diameter (d1, d2, d3), length (l1, l2, l3), and radius (r). It specifies the number of flutes (z) and other geometric features.

Procedures and Recommendations:

Milling Techniques: Recommendations for milling techniques such as climb milling and conventional milling are provided, along with cooling methods like emulsion and MQL (Minimum Quantity Lubrication).
Tool Features: The end mills are described as having high precision with a radius tolerance of +/- 0.005 mm and diameter tolerance of h7. They are center cutting with clearance between the shank and flute up to 5 times the diameter.

Key Data from Tables:

The tables provide a comprehensive overview of cutting parameters for different materials, highlighting the optimal conditions for achieving the best tool life and performance.
Effective working lengths at various draft angles are specified for different tool catalog numbers, indicating the versatility and adaptability of the tools for various applications.

Contact Information: The document concludes with contact details for Pokolm Frästechnik GmbH & Co. KG, including their address in Germany, phone, fax, and website for further inquiries.
