DescriptionAccurate engraving is not possible without an engraving machine. The aluminum frame engraving machine is more durable, stronger, and has a long service life. The engraving machine with the industrial-grade chip and 75W high-power spindle motor takes a very short time to complete the engraving, which is more highly efficient.SpecificationColor: Blue, SilverMaterial: Aluminum, Wood Maximum Workpiece Thickness: 78mm/3.07inchEffective Stroke: 400*400*83mm/15.75*15.75*3.27inchDrive Power: 12V 5A Spindle Power: 75W Voltage: 110V Power: 100W Spindle Speed: 0-10000rpm Spindle Accuracy: Radial Runout ≤ 0.05mmStepper Motor: 42 Two-phase Stepper Motor Rotation Speed: 6000rpmAcceptable Software: GRBL/Candle Communication Interface: USB Gross Weight: 12kg/26.46lbsEngraving Speed: 50-1500mm / min (Depending on the Material Speed Setting)Standard Spindle: 42mm High-Speed Spindle / ER11 Chuck / 3.175mm Clamping CentreWorkbench Size: 60*52cm/23.62*20.47inchProduct Size: 74.5*61.5*39cm/29.33*24.21*15.35inchPackage Size: 67*39*29cm/26.38*15.35*11.42inchPackage Included1 Set* Carving Bit1* Z Probe1* Right-Y-axis1* U Disk1* USB 1* Power Supply1*Power Cable 4* Clamps1*ManualOther Accessories for InstallationNotes1.Please read the manual completely before installation and use.
