Ultrafast femtosecond laser cutting machine

Abstract

The invention discloses an ultrafast femtosecond laser cutting machine. The ultrafast femtosecond laser cutting machine comprises a bearing platform, wherein multiple support rods are arranged at the lower end of the bearing platform at equal intervals; damping devices are arranged at the lower ends of the support rods, and a connecting rod is connected between every two adjacent support rods; a bearing plate is arranged at the upper end of the bearing platform, first electric sliding rails are arranged on two sides of the bearing platform, second sliders are mounted on the first electric sliding rails, mounting blocks are arranged at the upper ends of the second sliders, first vertical plates are fixed at the upper ends of the mounting blocks, and a mounting plate is arranged between the two first vertical plates. The ultrafast femtosecond laser cutting machine had the remarkable advantages of being high in machining speeds, high in accuracy, simple in parameter setting and the like through femtosecond laser cutting; a product obtained through femtosecond laser cutting does not have the problems of microcracks, breaking or fragments in the aspect of appearance quality; no contamination or edge breakage are caused, and the edge breakage resistance is very high; washing and polishing are not required, the manufacturing cost is reduced and the ultrafast femtosecond laser cutting machine is suitable for popularization.

Description

Technical field [0001] The invention relates to the field of laser cutting, in particular to an ultrafast femtosecond laser cutting machine. Background technique [0002] The important role of laser technology in national economy and social development: laser technology is one of the four major inventions in the 20th century that are as famous as atomic energy, semiconductors and computers.

Problems solved by technology

Its obvious disadvantage is that it requires high equipment capacity, often requires multiple repeated cutting or pre-processing, and the practical cutting efficiency is low. With the increase of cutting speed, the slag changes from a flat shape to a directional corrugated shape; when cutting from low speed to high speed The reduction of the superposition degree of individual pulses makes the slag change from a planar state to a discontinuous state. Therefore, we propose an ultra-fast femtosecond laser cutting machine to solve the above problems
