Fiber Laser Cutter

Why so many chinese fiber laser cutter with 0.2mm to 0.5mm accuracy difference after half or one year’s running?(lisa)

Laser machine quality is decided by: 20% laser power technology+ 20% gas control+ 20% optical
parts+ 20% Mechanics and motion parts+ 20% machine building technique.
The last 20% can make the first 80% meaningless

1) Machine table must have annealing treatment for inner stress relief before rough machining,and then have secondary vibratory stress relief before fine finishing. This is to effectively release the stress caused by welding and machining. Ifthese work missed or not 100% done, it is impossible for the machine table to offer long-term stability.

The Standard machining process work of fiber laser cutter as follow,

Welding—annealing treatment to release inner stress—rough machining—vibratory stress relief—second level machining—vibratory stress relief—third level precision machining.

Frankly many factories know this job, but they don’t know how to do it right or don’t want to spend money on such invisible work, just because cheaper price is their warranty of order.

2) Factory uses copy fiber laser cutter parts to compete on price.

Like gear rack, guide rails, planetary gearbox…etc. the copy cost is just 1/5-1/3 of original cost. The users can not easily to find the difference on new machine.

About such mechanical item, even the copy and original put together in front of you, you can hardly tell which is original. But after machine running some time, you will see it what problem happens. It’s hard for foreign end-user to know the parts cost to figure out which is a reasonable price of a machine. But those brand parts price depends on quantity, then with same machine parts, how can a small factory have cheaper cost than big factory?

There’s a old saying in chinese business: what you paid, what will you get
