CNC Milling FAQs

Zintilon has vertical CNC milling machines, horizontal CNC milling machines and multi-axis CNC milling machines. Vertical CNC mills are cost effective and have a wide range of applications. Horizontal CNC mills are used to cut grooves and slots in products and are ideal for cutting geared workpieces. Multi-axis CNC mills are CNC mills that can operate on more than four axes, allowing for the manufacture of more complex and precise parts.

CNC milling is suitable for machining parts with complex shapes, feature planes and irregular surfaces, such as grooves, gears, threads and special molded surfaces for dies and molds.

CNC milling machines are compatible with a wide range of materials, including metals, plastics and composites. Most commonly used are metals such as brass, titanium, aluminum or steel, and plastics such as PVC, ABS, polycarbonate and polypropylene.
