How to choose a fiber laser marking machine area?

Table of Contents

Today I got an inquiry about fiber laser marking machine. This customer wants to have a maximum marking area is 320*320mm area. But he was asking for a laser with 30W. This can not say okay or not. As a fiber laser marking machine always need a focus distance. If a fiber laser marking machine with a 320*320mm marking area that means we need to use a F470 lens on the fiber laser marking machine. A F470 focus lens the focus distance is about 550mm. So this means when the laser come out from the fiber laser marking machine, it is far away from the marking object. This means the fiber laser marking machine will low power to engrave or mark on the objects which you want to use the fiber laser marking machine to engrave on it. So this seems like we choose a big truck but we only use a small engine. This is not a good solution for a fiber laser marking machine. However if we want use bigger area fiber laser marking machine, what we need to do it to change a fiber laser source accordingly to fit the bigger marking area.  This customer said that his part height is about 400mm, that means if a fiber laser marking machine use F470 lens focus distance plus part height need about 1000mm stand to make sure the fiber laser marking machine have enough travel distance. What’s more, this customer also need a enclosure for this machine. Then we need to make a very big cover for this machine. This became a big fiber laser marking machine. In this way, buyers need to consider if you have enough place to place the fiber laser marking machine.

A 20w fiber laser marking machine is good wtih a focus lens 110*110mm

A 30w fiber laser marking machine is good with a focus lens 175*175mm

A 50w fiber laser marking machine is good with a focus lens 220*220mm

But this is not a final as if you want more strong power you can choose a smaller lens.

There is always a solution for you to choose a correct fiber laser marking machine.
