numerical machine tool card knife appears how to do, how to solve? from as7abecom's blog

tool holder is a common auxiliary device of numerical machine tool, which can complete a variety or even all machining procedures in the workpiece once clamping, in order to shorten the auxiliary processing time and reduce the error caused by multiple installation of the workpiece in the machining process, so as to improve the machining efficiency and machining accuracy of the machine tool.

In simple terms, there are two situations in the process of tool change, one is that the tool is not unplugged, the other is that the tool has been unplugged, the first situation is relatively better to solve, we mainly introduce another solution for various situations.

1, loosen the brake device on the motor, rotate the outer hex on the motor with an adjustable wrench, the general direction of rotation and the direction of the knife arm is the same, in short, let the automatic tool change the knife arm out of the spindle of the high-speed vertical machining center.

2, when the tool arm is out of the spindle, if the spindle has a tool can hear the sound of leakage, that is, the spindle is in the state of loose knife, it is necessary to pay attention to, be sure to pad something on the tooling, the tool has fallen at this time.

3, please keep rotating the knife arm until the knife arm has completed a complete knife change action. The knife arm also has an origin position, in the knife library panel, there are three red lights, generally the middle of the light is the knife arm at the origin position of the indicator.

4, after eliminating the fault, the knife arm motor brake device back to the original position, and then in the flat line rail machine tool in MDI state for the second tool change action, to see whether it is normal, if normal, please remember to process all the knives to be used to check again, in the case of ensuring safety in the processing.

Note: Before the tool setting operation of numerical machine tool tool compensation, the tool compensation value of all tools should be cleared first. In the tool setting operation of tool compensation, the tool should be replaced manually when the tool compensation value is not set.
