Laser marking machine needs to be processed for different thickness of the workpiece, if the focal length is not accurate, then can not play the best results, so how the mechanical structure to be adjusted up or down to adjust the focal length is the most important thing. To know laser marking machine is an optical instrument was born, and optically used to measure light gathered on the main is the focal length of. Here to see how to simply lower laser marking machine for focusing action.
Usually on the market for existing models, there are two ways to focus the following, one table lift, the second is lifting resonator. What is the difference be? First stage lift is currently the most used approach, the principle is simple, low cost, mainly rotating pulley to move up and down the media, with a guide bush and nut rotating parts, can be controlled through the table top rotary switch the angle of adjustment, enabling adjustment of the focal length. There are also some in order to save, with electric lift table movements in the reduced workload, although theoretically possible, but the marking machine industry is concerned, it is a waste, because the electric control, although more effort, but for focus control is not very accurate, and the speed and hand-lifting the same effect, so just a waste.
The lifting resonator is to use laser marking machine internal cavity shape of two mirrors and their relative positions, reflections of the light source, optical resonator is also reflected into the cavity and the projection chamber, no matter what one kind of resonator is a laser marking machine for lifting beam used for focusing. Since the focal length of the question relating to playing laser marking machine performance and quality, and therefore will not just change. A good lift platform can greatly improve marking machine stability in production, it can also be combined with mechanical principles pipeline use.
To sum up, since the focal length of the question relating to playing laser marking machine performance and quality, and therefore will not just change. A good lift platform can greatly improve marking machine stability in production, can also be combined with mechanical principles pipeline i use laser printing.
