Sheet Metal Process

Hi,

U can try out wit EDM wire cutting process.

Thanks,

Laser.

It all depends on what your requirements are, and how much you are willing to spend. Here is a good site for comparison of laser, water jet, oxy fuel, and plasma.

If you only need straight cuts, a Hydraulic shear is by far the quickest.

Thanks for this important link to compare the processes.

Do you have any link which can give speed charts for Laser, Waterjet, Plasma and oxy fuel?

Regards,

How precise are you talking? .5 mm, 1 mm, 2mm

How straight does the cut have to be?

Will there be additional machining on the edge after it is cut?

It must be within limit of +/- 0.08 mm

Profile will be complex and not straight.

No there will be no secondary operation but it must cut smooth.

Those requirements rule out laser, water cutting and all other non-contact processes.

Your only options are wire EDM and milling.

If U want this much Accuracy Then U must go for WEDM only.

In this We have highly control and accuracy.

Thanks,

Can't you secondary operation take up any slack so that making the first cut would not have to be so percise.

You never made it clear are you cutting lenght or are you cutting width? Stamping is the best way I know to get percise cuts of a design or cutout from the inside of a sheet because the metal is held in place while it is cut. But cutting lenght ot width have different stresses.

PLease define precise accuracy. Example: +/-.010", +/-.001", +/-.0001. Precise means different things to different people. You can cut sheet metal with punch, plasma arc, laser, waterjet, or wire edm. How close do you want it and how much can you pay?

what is it about you guys that feel you have try to assist someone you do not know and are competing unfairly for our jobs?

What is it about you guys that feel the need to abuse someone you do not know rather than participate in the mutually beneficial spirit of this forum? Also, if you are going to whine, please have the courtesy to introduce yourself by registering on CR4. Although with your attitude, you may find yourself unwelcome.

If we know your requirement in details. We will send your some useful information and send some catalogues of the machine. henryzhang1@hotmail.com

My requirements are to cut SS/MS ranges 5-50 mm thick.

If possible glass and stone but very little requirements.

You can send an email to rakeshmdc@gmail.com and in return I shall send you my mail address to enable you to send me catalogues and other technical information.

At first I would have said you would be better off doing it with a laser, waterjet cut, or maybe a CNC plasma cutter but with those tolerances of only a few thousandths of an inch it would have to be a wire EDM or mill out the profile.
