Laser Heads for CNC Machines Lasers for engraving, cutting, marking and related applications. Our laser engravers can be controlled by the PWM spindle signal, powered by 12 – 24V and mounted universally. This allows our engravers to be quickly connected to most CNC mills. In addition to CNC machines, our laser heads can be mounted in many 3D printing machines due to their compact and lightweight designs. Novel blue semiconductor laser technology contributes numerous benefits for engraving lasers. These include high power levels, a greater engraver operating temperature, increased absorption of materials, reduced focus spot sizes and a longer lifetime of the laser head. Our engraving lasers are a modern alternative to CO2 lasers for many applications.
