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 switched to devices there are many different categories to different situations differently. For example, the rotary turret tool change depending on the object to be processed, can be designed in various forms Quartet knife and hexagonal turret, 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 for rotating terms, as well as the replacement tool change spindle head. Spindle head usually have 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.
Some of the engraving machine will have a lot of work processes, the time you need knives library automatic tool change system. It's a tool change process is more complex, this approach can be a variety of complex processing procedures, especially the most widely used on CNC drilling machine, CNC milling and CNC boring.
