Fiber Laser Cutting Machine

A fiber laser cutter concentrates a focused beam on the sheet and melts or vaporises
the material, with a coaxial gas jet clearing the kerf. Because there is no mechanical
contact and no hard tooling, the same machine cuts different shapes, materials and
thicknesses with nothing but a program change. That is the real economic argument: it
removes the tooling changeover that governs turret punch and shear-based blanking.

1. Power class

Laser power sets the maximum thickness you can cut economically, and the speed at
which you cut thinner material. Two things are usually misjudged here. First, power
buys cutting speed on thin material far more than it buys thickness
capability — the relationship between power and maximum thickness is not
linear. Second, running a high-power source at low duty to cut thin sheet costs you
more per part than a correctly sized lower-power machine. Specify against your actual
thickness mix, not against the largest thickness you might one day see.

2. Bed size and loading

Bed size must match the standard sheet you buy. Loading method then divides machines
into two classes: manual loading, and exchange-table or automated loading. For a shop
running a single machine across mixed jobs, an exchange table is often the single
biggest throughput gain available — it removes the idle time while the finished
sheet is unloaded.

3. Assist gas strategy

Assist gas does two jobs: it clears molten material out of the kerf and it controls
the edge chemistry. From cheapest to most costly it runs roughly nitrogen, air,
oxygen — and each choice changes both the achievable edge quality and the
per-hour running cost. Gas selection is a cost decision as much as a quality decision,
and it should be settled before the machine is ordered, because it drives the nozzle
and gas-delivery configuration.

4. Nesting software and control

Material utilisation is where the money is. A nesting package that fills the sheet
properly typically beats a faster machine running bad nests. Look at how the software
handles common-line cutting, remnant management and automatic nesting across a job
queue — not just at whether it can import your file format.

WILAMAC supplies installation and commissioning, operator training, spare parts and
ongoing technical support. Consumables — nozzles, protective lenses and filters
— are the day-to-day running cost of any laser, so confirm the local availability and
lead time of these before you commit to a machine, whichever supplier you choose.
