Use of CNC engraving machine is very common, but some use for it may not particularly understand some users, in this to tell you about its automatic tool changer mechanism.
CNC engraving machine device has many components, different structures have different characteristics. Rotary knife tool change, depending on the object, can be designed into square turret and turret hexagonal forms, were installed on more than the rotary turret, press the NC device ATC instruction. Rotary knife in the structure must have good strength and rigidity to withstand the cutting resistance when roughing. Because machining accuracy depends largely on the tip device in for CNC engraving machine, the process is not carried out manually adjust the position of the tip, so the more necessary to select reliable positioning solutions and rational positioning structure to ensure rotary knife after each translocation, with the highest possible repeat positioning accuracy.
CNC engraving machine tool changer according to different devices also differ. Such as rotary engraving machines, the need to have a replacement tool change spindle head, usually with both horizontal and vertical, and commonly turn Datta translocation to replace the spindle head, in order to achieve automatic tool changer. At each spindle head of the turret, the first step of the installation of the required rotation, when the tool change command is issued, sequentially to each of the spindle head machining position and replaced through the main movement, so that the corresponding spindle is rotated, and other spindle is not processing positions are disengaged from the main movement.
Since the working process of CNC engraving machine is more complex, so the tool change process is also different.
