An engraving machine performance is mainly decided by engraving speed, strength, and spot size sculpture. Engraving speed engraving speed refers to the speed of movement of the laser head is usually represented by IPS (inches / sec), bring high-speed production efficiency. Also used to control the speed of the depth of cut, for a given laser intensity, the slower the speed, depth of cut or engraved greater. You can use the panel to adjust the speed engraving machine can also use the computer to adjust the print driver. In the range of 1% to 100%, the adjustment is 1%. Hummer machine advanced motion control system allows high-speed engraving when you still get super fine quality carving sculpture carved intensity strength refers to the strength of the material onto the surface of the laser. For a particular engraving speed, the greater the intensity, cutting or engraving depth is greater. You can use the panel to adjust the intensity of the engraving machine, but also can take advantage of the computer's printer driver to adjust. In the range of 1% to 100%, the adjustment is 1%. The greater the intensity, the equivalent speed is greater. The deeper the depth of the cut spot size of the beam spot size can be the use of different focal length lenses can be adjusted. Small spot lens for high-resolution engraving. Engraved spot lens for lower resolution, but for vector cutting, it is the best option. Standard configuration of new equipment is 2.0 inches lens. Its spot size in the middle, for a variety of occasions.
