Features: Router machine, operated through computer numerical control (CNC), can cut along various axis, no matter horizontal or vertical it is. CNC engraver can make a precision part made of one soft solid material (like wood), ensure a strong whole part, better than 3D printing. 775 spindle motor with an ER11-style chuck, efficiently drives the machining process, determines it to cut wide range of materials. The engraving machine uses ER11 collet (3.175mm) that fast, easily attaches the bit to the spindle, for better work. Three refined axis, to achieve flat engraving, provide a large effective working area of 300(X)x180(Y)x40(Z)mm (11.8inx7.1inx1.57in). Offline controller can download and save files (no need to connect a computer), control to directly do some simple carving (no need to download any files). You can connect the engraving machine to computer via USB port, control its movement with stable GRBL software, very convenient. Whole machine body made of high hardness aluminium, coated with black finish to resist rust, looks nice and lasts for a long while. It is suitable for DIY enthusiasts to have engraving or milling on wood board, plastic, leather, PCB, bamboo, PVC and more.
