I have made several projects from steel on the xcarve from 22 gauge sheet to .25in plate and bar. And I will tell you this much take your time and be patient and use lots of coolant this will take a while. I have tried out many types of bits feeds and speeds and what is working for me on a 1000mm I will post below.
1 on the dewalt
plunge 1ipm 25.5mmpm)
depth per pass .005in (.127mm)
and this is the bit i have been using for some time now
here is the closest I could find on fleabay that the right one was cut with
imco left china right
Cool, What type of items are you making with the steel?
At the moment I am making a custom keyring per customer specs. one piece is cut with a cheapo china carbide and the other is cut with the imco I will post pics later of the vast difference between the 2 tools. The china tool cut piece is gonna need a lot of filing. And I mean a lot.
types of items made.
edc multi tools
other odd and end things
Isn’t the dewalt going too fast for steel?
On the order of several rpm too fast. But when they are willing to pay $$ for a hour of my time then a steel trinket they shall have. We shall call this method P.F.E.P. (power filing with extreme prejudice) lol. I would choose to march to the beat of a different drummer but I can not find one that will follow me.
I bought this machine to push it past what it was ever meant to do with the intent to build my own. I got this machine mid 2015 and fully expected to put it in the scrap pile in a few short months boy was I wrong. I will share my list of all the replace meant parts I have had to buy.
- Arduino nope did not need it was a error of mine and it is fine.
2.Dewalt upgrade but who didn’t move away from the default spindle
- Xrail mod then new x rail. could have lived with out the upgrade but very happy I got it
- Dewalt brushes we all need them. 3rd set as of now.
- bits lots and lots of bits.
Well I guess it was useless to make that list as nothing except the original spindle has failed. And still on the same set of drive belts v wheels and pulleys. You guys have a great job and I will let you know when something finally gives.
How is the noise? Would it be worth a 10 hour loop on youtube?
really no different than anything else until you dull or chip a bit then dogs around the world cry.
You could try one of those cheap router speed controls from harbor freight, there only like $10 and should slow down the RPMs
Maybe if were a ball screw set up but the belts can not take the load required for proper milling. Currently in the process of gathering materials for a bench top cnc mill.
@ShaneBell What are you using for coolant?
I now have access to cnc coolant but at the time i was using whatever oil i had in the shop.
I am gearing up to do some bigger steel so thanks for your info. did a bit of small parts that worked out ok. And i have done a bunch of aluminum and seem to have that down. aluminum can be tricky if you try and go to fast too…gumming problem etc…steel just needs as you say a LOT of patience. fingers crossed. i’m thinking of a small recirculating tray system for coolant. get a small t-slot table and bolt it all down.
Had a few questions:
From which direction did you cut (down from top into material, or create a way to start from the side)?
You slow the cut head (dewalt) all the way down?
The link you provided takes you to a page with many bits, which bit did you go with?
1/4” shank on the but, I assume?
