CVD

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. The focus is on achieving the sharpest cutting edges and highest tool life.

Specifications:

The end mills are made of solid carbide with CVD cutting edges, ensuring high precision and durability.
Available in various diameters and lengths, with specific catalog numbers for easy identification.
Features include center cutting, ball nose, and clearance between shank and flute up to 5x diameter.
High precision with a radius tolerance of +/- 0.005 mm and diameter tolerance of h7.

Material-Specific Parameters:

Different materials such as AlSi, glass ceramic, PMMA acrylic, and various composites have specific cutting speeds (Vc), depth of cut (ap), width of cut (ae), and feed per tooth (fz) values.
Cooling methods and milling directions (climb or conventional) are recommended based on the material being processed.

Tool Geometry:

Ball nose end mills and corner radius end mills are available, each with specific geometrical features like chip angle (γ) and helix angle (λ).
Effective working lengths are provided for different draft angles.

Recommendations:

Use emulsion or MQL (Minimum Quantity Lubrication) for cooling, depending on the material.
Climb milling is generally recommended for most materials, with some exceptions for conventional milling.

Contact Information:

Pokolm Frästechnik GmbH & Co. KG, located in Harsewinkel, Germany, provides these tools and can be contacted for further information or custom diameter requests.
