ATC CNC Router
There are two kinds of tool changing type for the ATC CNC router.
1. Straight line tool changer, economical and practical. The tool bank is installed in the bottom of gantry, the tools handle is arranged side by side, and all the tools are put out by the tool bank. The tool is selected by the spindle to save a suit of motor and drive device. The system can use three-axis system.
2. Disc tool changer, the tool bank is installed on the spindle or gantry side, choosing the suit bit by rotating the disc tool bank which is driver by servo motor. The tool bank and its span is small, and more stable. It needs another sets of servo motor and drive. The system needs four axis system.
ATC CNC machinery usually requires 3 axes to complete the engraving work, called X, Y and Z. The X axis is horizontal, the Y axis is vertical, and the Z axis is perpendicular to the other two axes. The spindle holds the tool and moves along the X, Y and Z axes, following the tool path generated by the software. In addition, there are some ATC CNC Router+4 axis engraving machines with X, Y and Z axis rotation axes (fourth axis). These CNC router engraving machines are mainly used for some cylindrical engraving and cutting work.
