5.3  CNC tool changers

Fig. 4.5.9 CNC tool changer

In the CNC tool changing mechanism the tool magazine has to be indexed to bring the desired tool in line with the tool changing arm (Fig. 4.5.9). The tool changing arm picks the cutting tool from the spindle. Then it is indexed to reach the tool magazine. The tool is placed in the magazine. Then the magazine is indexed to bring the next cutting tool to be picked by the changing arm. Again the tool changing arm indexes to reach the spindle.

Here a rotary index table is used to convey the parts for inspection operation. This index device conveys the parts in a rotary motion and stops intermittently for a fixed period of time for inspection. A cam mechanism is used to index the table (Fig. 4.5.10).
