Features: 1. 40W super powerful laser: SF-A9 40W uses a 40W laser head, which has super cutting ability and supports power switching. It uses a heat pipe radiator for faster and more balanced heat dissipation. The front lever of the laser head can quickly adjust 40W/20W to meet different processing needs. It can cut 20mm plywood and 6mm dark acrylic at one time. 2. Precise focusing design: SF-A9 has the most precise focusing design on the market. The laser head has a built-in fixed focus piece, which is stable and does not shake, and the fixed focus position is more accurate. The focus positioning structure is equipped with Z-axis manual adjustment. The red knob on the right side of the laser is for quick up and down adjustment. The knob on the top of the laser is for precise adjustment, with an adjustment of 1mm per turn. You only need to slide the positioning switch to quickly position the height and manually adjust the height to achieve precise micro-adjustment of the focus. 3. Sturdy and easy-to-install structural design: The metal structure design makes the machine very strong. The feet have a leveling structure. The X-axis uses industrial-grade linear guides to make the body very stable and improve the accuracy of engraving. The movement accuracy is 0.01mm. The Y-axis adopts an adaptive roller, which eliminates the need to manually adjust the distance between the roller and the guide structure. The resistance is small, the operation is smoother, and the installation is simple. The user does not need a lot of wiring. It is very friendly to new and old users and is quick to use. 4. Multiple connection methods: with wifi, usb, and bluetooth functions. Supports the following operating systems: Win7/Win8/Win10/Win11/MAC/IOS/Android. Compatible with mobile APP (SculpFun) or computer software (Bluetooth function can connect to Lightburn and LaserGRBL without data cable), very convenient to use. 5. Safe design: equipped with emergency stop switch and key switch. And it has built-in flame, temperature sensor and tilt sensor. When a processing fire is recognized, the flame and temperature sensors will be triggered, and the laser will stop working and alarm. The laser will automatically move to the safest position. If the machine tilts more than 15°, it will stop emitting light and alarm. 6. High-speed drive: The machine supports precision mode. When you want to cut an assembly, turn on the precision mode. The parts will be cut very accurately and the assembly will be more suitable; The machine supports high-speed engraving mode, the speed can reach 36000mm/min, the body is stable and does not shake, and the engraving effect is beautiful and efficient. 7. Air assistance: Large inner diameter air pipe, better air channel design, no connection between the air pump and the laser head, leaving enough bending space to reduce wind resistance. Compared with other machines, the cutting effect is more beautiful and clean. When the machine is not working, a small amount of protective air will be blown out to prevent the lenses from getting dirty. 8. Expandability: The height of the feet can be adjusted, and the feet can be expanded and increased to facilitate carving of taller objects to meet different needs.
