View Full Version : CNC laser cutting

I recently had some pieces cut for mounting my york air compressor, the quality was very nice and it was definately not as expensive as water jet.

they look great,
do you mind me asking how much? and what are the approximate dimension we are looking at? like 6 inch long for the big one or more like 12"?

there are the dimensions and for the 2 main pieces ie the curved piece and the smaller square shape with the piece sticking off it i was quoted at 89ish dollars to be cnc cut out of 1/4" cold roll. the whole set would be around 150 i believe.

Really does make a nice looking job. I wish I had a closeby source for this kind of work, but I'm at least a hundred miles from the nearest vendor, so the cost goes up accordingly. Waterjet is nice, but just like anything else, you gotta be where the demand is to be able to take advantage of it. I'm still cutting and grinding, and sanding. But I ain't trying to make a living from it so I guess it keeps me out of the Bars all day.

Hi guys im kinda lucky in one respect as im employed in a laser cutting shop so i have no problems with making parts for my own use .
As far as water jet Vs laser cutting I'll have to say that laser always wins first time.

The guy across the road from me has just installed a really advanced type of waterjet that has capabilities I didn't know were possible - hopefully I can take advantage, because he bought it for his own use and it only runs about 25% of the time :wink:
I have used laser quite a bit in the past, but I think this machine will definately have the edge. Also especially good for tool steels or other heat affected materials.

Make sure you don't scew up any hole sizes, particularly where using 4130N sheet. Most laser cutting uses some form of gas assistance, the people I use here in Australia use an oxygen mix apparently. This case hardens the edge of all cut surfaces, making incorrect diameters etc impossible to drill to size. Also if you need to cut across any lasered edge, you will need to lightly linish the ecge to prevent any saw blade becoming very quickly dull.

..., you will need to lightly linish the ecge ...Rod
It will also case harden the burr edge on sheet metal. We had a bunch of laser cut 18ga at MM04 and before we realized it a BUNCH of ewheel rollers were 'marked up' Folks were doing interial starts and score lines across the contact area. Everything but Hoosier heat treated stuff (51Rc) got cut. Once we realized what was causing it we just told folks to debur the edges with a file.

Nice UK / Australian term. Means SAND. Filing as you suggested would also work.

Ah David thanks. I bet you Googled it didn't you?
The UK world has some neat words. I used to run across "Bespoke" once in a while...as in "Bespoke project" or "Bespoke Savile Row suit". Finally asked what the heck it meant....means custom.

i run a laser and a waterjet, so i am luckey in that aspect, it is really nice too not have too grind and cut every part

I use a CNC router. Most definitely not fast but at least I can cut parts in-house. In real life I use it to cut signs.
I've made dozens of parts for the "Z" on the CNC, aluminum & mild steel. And, just about all the trim & most of the cabinets in our home. Sure is handy to have around.
