CNC engraving machines in our lives has been very common here to tell you about the work of the mysteries of its automatic tool changer.
Engraving machine change to the device there are many different categories to different situations differ. For example, rotating turret tool change depending on the object, and can be designed into square turret Turret forms, were installed on more than the rotary turret, numerical control device according to ATC instructions. Rotary knife in the structure must have good strength and rigidity to withstand rough when cutting resistance. Since machining accuracy depends largely on the tip device on the CNC engraving machine, tool tip position during processing without manual adjustment, it is necessary to choose more reliable positioning solutions and rational positioning structure to ensure rotary knife after each translocation, with the highest possible repeat positioning accuracy.
CNC engraving machine for rotating terms, as well as the replacement tool change spindle head. Spindle head usually has both horizontal and vertical, and commonly turn Datta translocation to replace the spindle head, in order to achieve automatic tool changer. In each of the spindle head of the turret, the first step is attached to each of the required rotation, the tool change when issuing the command to turn the spindle head machining position and replaced through the main movement, so that the corresponding spindle is rotated, and other spindle is not processed are disengaged position on the main motion.
Some of the engraving machine work when there are many processes, then you need knives library ATC. It's a tool change process is more complex, this approach can be a variety of complex machining processes, especially the most widely used in CNC drilling, CNC milling machines and CNC boring.
