木質(zhì)激光雕刻機：

木材激光雕刻機一般用于木材加工的切割和雕刻，木質(zhì)材料激光雕刻形式可分為切割雕刻、凹模雕刻和凸模雕刻三種。激光雕刻的材料去除原理與激光切割相同，多條未切透的切槽連在一起就形成成面積的材料去除。激光切槽的橫截面呈“V”形，切割速度越低、激光電流越大，切槽寬度和深度也越大，其中切割速度和激光電流對切槽深度的影響程度比對切槽寬度大得多。

木質(zhì)材料激光雕刻加工的基本原理與激光切割加工基本相同，都是利用高能量密度的激光束轉(zhuǎn)化為熱能，瞬時引起木材熱分解和炭化，從而去除部分材料。激光切割是將木質(zhì)材料(主要是板材)的不同部分分離開，而激光雕刻是在木質(zhì)材料的表面加工出要求的圖 案、花紋和文字等。對同一木板講，激光切割所需的能量較大，而激光雕刻由于不需要切透工件，故所需的能量相對較小。激光雕刻是非接觸式加工方法，與傳統(tǒng)機械加工方法相比具有無木屑污染、無刀具磨損也不需更換刀具、無噪聲污染(噪聲很低)等優(yōu)點。激光切割頭聚焦透鏡將激光聚焦至一個很小的光斑，光斑直徑一般為0．1～0．5mm。激光束焦點位于待加工表面附近，用以熔化或汽化被加工材料。與此同時，與光束同軸的氣流由切割頭噴出，將熔化或汽化了的材料由切口底部吹出。

技術(shù)優(yōu)點：

金米蘭激光研發(fā)團隊從根本上解決因激光設(shè)備對各類木材料雕刻切割時出現(xiàn)的速度慢、雕刻深度淺、切割邊鋸齒狀、邊線不光滑等缺點。同時可以采用視覺定位等最新技術(shù)有效解決精密切割、高速雕刻技術(shù)難題。

Wood laser engraving machine:

Wood laser engraving machine is generally used for cutting and engraving of wood processing. The laser engraving form of wood material can be divided into three types: cutting engraving, concave engraving and punching engraving. The principle of material removal by laser engraving is the same as that of laser cutting. A plurality of uncut slots are joined together to form an area of material removal. The cross section of the laser grooving is "V". The lower the cutting speed, the larger the laser current, the larger the grooving width and depth. The cutting speed and laser current affect the grooving depth more than the grooving width. Much more.

The basic principle of laser engraving of wood materials is basically the same as that of laser cutting. They use high-energy density laser beams to convert into thermal energy, which instantaneously causes thermal decomposition and charring of wood to remove some materials. Laser cutting separates different parts of the wood material (mainly the board), while laser engraving processes the required patterns, patterns and text on the surface of the wood material. For the same board, the energy required for laser cutting is large, and laser engraving requires relatively little energy because it does not need to cut through the workpiece. Laser engraving is a non-contact processing method. Compared with traditional machining methods, it has the advantages of no wood chip contamination, no tool wear, no need to change tools, no noise pollution (low noise). The laser cutting head focusing lens focuses the laser to a small spot with a spot diameter of typically 0.1 to 0.5 mm. The focus of the laser beam is located near the surface to be machined to melt or vaporize the material being processed. At the same time, the airflow coaxial with the beam is ejected by the cutting head, and the melted or vaporized material is blown out from the bottom of the slit.

Technical advantages:
The Kingmilan laser R&D team fundamentally solves the shortcomings of slow speed, shallow engraving depth, jagged edges and unsmooth edges caused by laser equipment for various types of wood materials. At the same time, the latest technologies such as visual positioning can be used to effectively solve the problems of precision cutting and high-speed engraving.

在線觀看視頻建議：
1、在有無線wifi環(huán)境下觀下，更加流暢；
