Feature: 1. Laser Module: 20W cutting module, capable of cutting 8mm thick plywood clean at once. The carving speed can get up to 1000mm/s. If compatible with other CNC devices, the module must correspond to the 12V application interface voltage. 2. Powerful Cutting: Can engrave plastic, wood, leather, rubber, acrylic, etc., or cut wood and acrylic. And the wattage determines its ability. 3. Safety Protection: Built in protective glass to protecting the eyes, making it more comfortable and safe without the need to wear protective glasses. 4. Intelligent Setting: The engraving module consists of two high performance diodes using FAC. The minimum focal point is 0.12 x 0.12 mm. Built in fast intelligent drive, temperature can be checked in time, fan intelligent setting reduces noise, carving job is safe and quiet. 5. Widely Application: For CNC machine tools, metal, PVC and multiple types of coordination. Can act on cardboard, non woven fabrics, veneer, acrylic, and some thin plastic sheets. Wood, bamboo, cardboard, plastic, leather, PCB board, aluminum oxide, non reflective electroplated coating and painted metal. Specification: Item Type: Laser Module Material: Aluminum alloy, ABS.
