What is the turret way in which the magazine is placed around the spindle?

In this way, the tool magazine itself is equivalent to the robot. That is, the tool is inserted through the tool magazine and the tool is changed in sequence. so that the cutting time of the machine to the chip is shorter. In this way, if any tool change is to be performed, the length of time varies depending on the position of the selected tool in the tool magazine. The farthest knife may take a long time from chip to chip change. Therefore, in this form as a high-speed automatic tool changer, only the sequential tool selection method can be used.
