The choice of high power metal cutting machine focus lens

Focus lens metal cutting machine is a kind of more precision optical components, and for the vulnerable components, its clean degree directly affect the processing performance and quality of cutting machine. For domestic high-power cutting machine tools, can choose the focus lens has a lot of kinds. Can according to the focal length of the focusing lens and focus lens thickness and cutting materials and so on to choose the appropriate focus lens.

from the focus lens thickness, thin lenses ( Less than or equal to the thickness of 6 mm) Often used for cutting nonmetal sheet, thick lenses ( Thickness is greater than 6 mm) Is often used for cutting sheet metal. Cutting metal material plate is easy to slag gush to the lens, so should be used when cutting metal thick lenses. In addition, when use the optics lens to cooling water cooling, in some of the light power a lot of

in the system, the focus lens and mirrors zama often needs to add indium wire to aid cooling. So, the timing of the focusing lens and maintenance is very necessary, maintain cutting machine focus lens correct operation process is as follows:

1, such as do need to clean the lens, can only use laboratory level paper soft cotton ball, dip in proper amount of acetone or high degree of alcohol, gently clockwise direction from the center of the lens

rotating brush to edge;

2, frames to retrieve focusing mirror: loosen the fastening screws, in turn off gas mouth and lens barrel; Use first blow the balloon away the dust on the surface of the lens;

3, packed tube, gas mouth, adjust the focal length, the tightly solid screw, focus lens installation please be sure to keep the raised face down.
