Description

1. Machine layout.
The machine is a structure with a steel welded supporting frame. Precision manufacturing is determined by assembly through tongue-and-groove connections and milling of critical surfaces.
The main advantage of the new design is:
• use of rolling guides for linear feed drives;
• absolute zero of all coordinate drives;
• high-speed drive (motor spindle) of the main movement;
2. Milling training and production machine in a protective cabin with an integrated CNC computer system
Machine power requirements:
— voltage 220 V/50 Hz;
— current consumption 10A;
— the machine body and all metal parts must be grounded.
