4-axis milling machines. Multi-spindle, twin-spindle, or single-spindle milling machines. We provide turnkey solutions for vertical, horizontal, and inverted milling with full automation options available—everything you need to gain high productivity. The 4-axis milling development has opened the door to high-precision milling. It offers greater precision and accuracy than traditional CNC milling machines that use 3-axis technology. Many parts and components manufacturers in the aerospace and automotive industries and other areas have switched to 4-axis milling machines to produce complex designs. This upgrade can increase productivity and save you both time and money. What does 4-axis milling mean? And what is the difference between 5-axis and 3-axis milling, respectively? We’ll explain everything you need to know about 4-axis and outline the MODIG 4-axis milling solutions.
