Reported by laser.ofweek.com—With rapid products renewing, it has
much higher flexibility demands on the processing equipment. The
application of laser cutting machine brings new vigor to processing
industry. Compared to traditional NCT, laser cutting machine features
advantages as cool, clean, calm, sure, safety and saving. However, they
have equal shares of market, why?
Below are five basic knowledge points of laser cutting machine and NCT.
1. Processed material
Laser cutting machine can cut metal material including ferrous metal
and nonferrous metals, such as carbon steel, stainless steel, silicon
steel, galvanized sheet, aluminum alloy, etc.. It can also cut
non-metallic material like acrylic, plastic, wood, cloth, leather and
carpet. The cutting thickness of carbon steel can reach to 20mm. NCT are
generally applied in metal with thickness no more than 6mm.
2. Processed flexibility
From the aspect of flexibility degree, laser cutting machine has more
advantages which can cut holes of any shapes or sizes; while punching
machine can be applied in limited specifications (the largest is 32
location turret), when it works on deformed or large holes, it will meet
problems as low efficiency and serious abrasion on mould by small step
mould processing.
In order to meet different demands of
various products, it is necessary to purchase plenty of moulds in
different size and thickness as well as a warehouse for storage, which
increases the work load of mould management. Besides, NCT has higher
requirement on the board plainness and cleanliness.
3. Precision and roughness
Laser cutting machine is non-contact processing, which features stress
free, no deformation, positioning precision of ±0.03mm, workpiece
precision of ±0.1mm and smooth cutting section; while NCT has slightly
poor processing precision, burrs on cutting surface and some
deformations.
4. Efficiency and cost
A factory once adopted
punching machine plus plate shearing machine, which needed more labor
than laser cutting machine. There is a comparison on the cost of laser
cutting machine (3kw fiber laser) and punching machine considering the
following items: electricity, consumable items (focus lens, ceramic
body, spray nozzle, gas for laser cutting machine; moulds for punching
machine), labor and depreciation of equipment. The result is that laser
cutting machine costs 179 yuan per hour and punching machine costs 174
yuan per hour. When processing all the sheet metal parts of a product,
laser cutting machine needs 0.2 hour while punching machine needs 0.7
hour.
Obviously, laser cutting machine has significant advantages
on efficiency and cost. Certainly, for huge quantities of product,
specially designed mould will enhance the efficiency of NCT
significantly, such as porous mould which has damage on flexibility.
5. Function and limit
Both of them have limits of their own. NCT is the only choice for
functions like window-shades, shallow-drawing, countersink, flanged
hole, reinforcing rib and coining; while for noise damping saw blade,
only laser cutting machine can realize it.
