When purchasing UV laser marking machines, customer enterprises attach great importance to the marking speed of the equipment, because it is directly related to the processing efficiency of orders. So, what factors will affect the marking speed of UV laser marking machine? Generally speaking, the main reasons affecting the marking speed of UV laser marking machine are divided into two aspects: one is the equipment itself, and the other is processing workpieces. The main reasons of the equipment are laser frequency, laser spot mode and beam divergence angle, laser power, reasonable optical shaping and auxiliary gas during processing. Customers should consider this aspect when purchasing UV laser marking machine. It is recommended to select the model according to the opinions of professional technical engineers. Another reason is mainly the marking density, marking format, marking depth and laser spot size during processing. Marking density: in the case of the same format, the same spot and the same depth, the higher the marking density, the slower the corresponding marking speed, because the density directly increases the marking area. Marking format: the marking speed of large format is slower than that of small format, because the deflection area of large format marking galvanometer increases. Marking depth: according to the demand, if you need to deepen the marking depth, you need to adjust the parameters of the UV laser marking machine and increase the power, current and other parameters of the UV laser marking machine, which will affect the marking speed.
