laser cutting and punching.

[Davimont]

I have worked for several years on laser stains and punching but without ever taking care of production costs.
for the customer who commissions a production, what costs him more?
The punching machine has a vast matrice punch park and it has to be kept efficient. after a tot of sharpening should be replaced and according to the material to be punched can also have different treatments. you do not work the high thicknesses as you can make the laser.

the laser has just those two or three cutting heads to maintain efficient, a couple of spare lenses and nozzles to be replaced occasionally.
the execution of the cut at equal thickness is clearly higher and also the quality is indisputable. a rounded curve can not compete with a laser cut.

I would like to read some opinion to understand how to move with my carpenters.
Thank you all.

Well the laser definitely has higher purchasing costs than the punching machine, then anyway the laser to cut always needs gas (oxygen or nitrogen)
Hi.

 

[Davimont]

be also the punching machine has constraints in keeping the tools in good condition. But I repeat that I have never dealt with it.
but by counting on the cheese card, having to produce a carpentry, can I start already with the idea that with a laser I will be required a higher figure? or depends on other factors?

In the company where I work we have a laser cut, but I can't tell you the costs.
But what I know is that in addition to the gas, as someone already said, it is necessary to consider that the maintenance costs are high, especially when it comes to extraordinary maintenance (breaks, malfunctions...).

if you don't need a high quality cut edge because you don't even see a plasma cut?
could be the middle way between laser and punching machine.

If they are always the same pieces of production, of a certain thickness and in large quantities, go on the punching machines.
If you have large thicknesses or geometries that change continuously then go to laser cutting, also because you have to consider the costs and time for the tooling of the punching machine.

thanks for the answers.
almost all of the work is 12/10 sheet metal carpentry and square forms. are so many tanks put together that form the car. So I understand that punching is the cheapest way. what I don't like is the residue of micro joints and roditures of the bigger holes but as I say in some cases " doesn't go to my house".
I also evaluated the plasma option, I worked several years on a high definition one and was not bad as cutting.
Thanks again to everyone!

How many pieces are we talking about? on so high thicknesses I think the laser is hardly staggerable. on thin lamiaere a stinger, if you give them numbers, is still unbeatable for costs and speed.
laser has completely made you forget the discounters, when you have complex silhouettes remains at the top.
the maintenance costs of the laser unfortunately are not negligible, are delicate machines.

Good morning to all,
in our company we have a rather old plasma cutting machine and evaluating between a punching machine and a laser had recommended a plasma with a drilling unit that could fill that in theory should be halfway between costs and benefits between a punching machine and a laser, considering that we do not make serial production.
