Question About Cutting Technologies

02/08/2008 12:27 PM

We manufacture components for the automotive sector which require two components to be cut with a TCT circular saw. Each component has its own compound angle. Once cut these two components are laid within a fixture and are then MIG welded into position.

However, the tolerences that are applied to the cut length to both of these components can cause problems within the welding facility. i.e. blow holes.

Saw blade life is the major concern to us due the number of regrinds that we are achieving before the blade is scrapped.

Personally, I do not feel that cutting these components in this way is the most cost effective and would like to ask whether there is any technology (non contact cutting for example) within the market today that will give us components which have a much better capability in terms of their cut lenghth dimensions and will also give us the benifits in our consumable spend of TCT blades.

I have asked questions to certain suppliers in terms of water cutting, but once the application has been explained to them, I am told told that this technology is not appropriate to our product. Our product is basically a flat tube with a number of internal galleries.

I hope that there my be some answers to our problem out there.

http://www.saw-lutions.com/ specializes in rotary parting saws for screw machines, if the flat tube can be fed through collets, this technology might work.

You did not specify any dimensions nor material nor angles, that would help us better understand your issues.

Abrasive saws are also a possibility. Even if only to cut blanks which could then be gang loaded on a pallet and machined en masse to proper geometry.

With more facts will certainly come more (and better) ideas.

So clemency requested if this idea is out of line. Insufficient details provided to have clear understanding.

Blades with cermet tooth. Their getting 10 times the life over carbide depending on the material cut. Cuts are cleaner cermet can be ground to a sharper edge than carbide. The blades are not that more expensive than carbide.

As far as non-contact cutting would have to know what you are cutting and angle of cut.

I understand the tolerance issue very well. Need more info.

Hello,

I am familiar with automotive technology, particularly metal cutting. I also have worked with tube cutting and MIG / TIG welding.

You have not supplied suffiecient information in order to get a good answer. Please upload a picture of the cross section (internal structure?) of the tube in question if possible. What are the sizes? What is the material? What are the tolerances to be held to give you a good weld (.050 " gap max I assume?). What is the volume of parts that you are running annually? Saw blade life can be increased by using the right coolant, if applicable - again - more info please.

There are blade cutting technologies out there that may be able to assist you, but more application details are needed.

Mirco.

Need dimensions (inside and out of tube ,thickness, material.) as well as tolerances. How many cuts per blade are you getting now? Are you using cutting fluids or air cooling methods ?
