¿Qué trampas se debe prestar atención a la elección de la máquina de corte de alambre?

At present, there are many kinds of wire cutting machines on the market, so
how to distinguish good from bad?

The first big trap: the fast wire bed is changed into a linear guide rail,
equipped with an electric cabinet with frequency converter to repair the knife,
which is known as high-precision medium wire cutting machine. The real medium
wire is essentially different from the fast wire in terms of machinery and
electrical appliances.

The second trap: only talk about the maximum processing efficiency, do not
talk about continuous cutting time, any cutting efficiency if not continuous
processing for more than 24 hours, there is no practical value. If the thread is
changed frequently, a lot of time will be wasted, which directly affects the
overall processing quantity in a day!

The third trap: only the lowest surface roughness, not how large the area can
be cut continuously, no matter how good the surface roughness is, in the case of
no need for human intervention, if it can't cut more than 20000 m2 continuously,
it also has no practical value, the index depends on whether it can reach RA ≤
1.0um/30000 mm.

The fourth trap: we only talk about the machining accuracy of a single small
size, but we never talk about the stability or consistency accuracy of
continuously cutting more than 30 pieces. In the batch continuous machining of
more than ten or even dozens of the same parts, the consistency of size is
particularly important. Note that the continuous machining here means that it is
not allowed to artificially detect and compensate the diameter of molybdenum
wire; Whether the target can be achieved, the consistency dimension error is
less than or equal to 0.005mm/30 pieces; Never talk about step precision,
ordinary stepper motor can't reach micron precision.

If we avoid these four traps, we can basically choose a high-quality wire
cutting machine.
