Tool changer in the machine tool spindle and tool changer between the exchange of tools, common for the robot; there is no robot and by the spindle directly with the tool changer, called armless tool changer. Machining center tool magazine is divided into disc type tool magazine and robot tool magazine two kinds of
First, disk type tool magazine
Disc type tool magazine should be called a fixed address tool changer tool magazine, that is, each tool position has a number, generally from 1 to 12, 18, 20, 24, etc., that is, for the address of the tool number. After the operator installs a tool into a certain tool position, no matter how many times the tool is replaced, it is always in the tool position.
1. Low manufacturing cost. The main components are the tool magazine body and indexing plate, as long as the two parts processing accuracy can be guaranteed, the moving parts of the tool magazine in the indexing of the use of the very classic "Ma's mechanism", before and after, up and down the movement of the main selection of cylinders. Assembly and adjustment is relatively convenient, simple maintenance. General machine tool manufacturers can make their own. 2.
2. Every time the machine tool must be turned on after the tool magazine "back to zero", the tool magazine in the rotation, as long as the block is close to the (distance of 0.3mm or so) no-contact switch, the CNC system defaults to the No. 1 knife. And as a counting basis, the "Mars organization" turned a few times, the current is the number of knives. As long as the machine does not shut down, the current knife number is memorized.
