CNC milling machine bamboo hat type tool magazine (Part2)

Today, let us talk about the tool change process of the CNC milling machine bamboo hat type tool magazine.

The bamboo hat type tool change is an absolute tool change, that is, after each tool change, the tool number and tool holder number is one-to-one correspondence.

Bamboo hat type tool magazine without the need to manipulate the tool, through the spindle box and spindle mechanism to achieve the linkage, the tool change process:

1) CNC system to get the tool change instructions, the spindle automatically return to the tool change point, while the spindle to achieve quasi-stop control.

2) The milling machine cutter rotates to the tool change point corresponding to the tool number (set to the old tool) on the current spindle.

3) The cutter head from the original position by the cylinder piston, when the clip to grasp the old tool on the spindle, the knife in place switch switch, said the grasping knife to complete.

4) Spindle knife action, the old knife loose, and the spindle cone hole blowing, when the spindle loose knife in place switch, said the loose knife to complete.

5) The milling machine spindle is moved up and the old tool on the spindle remains on the tool holder and the knife is finished.

6) The magazine rotates again, and the tool holder (set to the new tool) corresponds to the tool holder number to the tool change point.

7) The spindle is moved down again to the tool change point, the new tool is inserted into the spindle taper hole, and the tool change is completed.

8) Spindle knife action, the new tool in the spindle in the knife, when the spindle cutter in place switch, said the tight knife to complete.

9) Cutter cylinder cylinder retraction, when the knife reset switch is turned on, the tool change process is over.

The above is the tool change process introduction of the CNC milling machine bamboo hat type tool magazine, the next article we will introduce other types of tool magazines.
