I think I may have reached the end of the internet as a search for the perfect cnc for my needs. I've come to the conclusion that 6 inches of z clearance is about the deepest z cnc manufacturer’s offer. I’m looking for a CNC router that is around 24x48x12 I’d even be ok with a 10 inch stroke if I could find one. I’ll be milling large blocks of foam for 3d prototypes. My z axis will have to account for the large block plus a long bit with some room for clearance and travel. I would also like to do some small detail work so the resolution needs to be high and the backlash needs to super low. I would also like to do the occasional soft aluminum mills for things like key chains and small parts. My quest of finding such a machine has left me with very few options. I’m a small shop so I can’t break the bank on this purchase, but I was hoping maybe someone would be able to provide me with some additional options.
Finding 1: K2CNC offers a 24x39x12
This one is at the top of my list for purchase at the moment. The price is good it has all the features I want. Little concerned about the (.001” or .0254mm Backlash) but I maybe more misinformed if this is an acceptable amount for high detail work. I'm also a little concerned about some of the issues people are having with these machines over in the K2CNC forum. Any thoughts?
Finding 2: EZ CNC not to be confused with EZ Router
I found these guys because they’re here in Texas as well. They pretty much make custom size CNC machines. Their prices seem to be reasonable I like that they’re local and can help me find a machine that will fit my needs. I’m a little concerned about custom building a machine that could potentially have bugs and kinks to be worked out. I also have a feeling it’s going to be more expensive then the K2 model when everything is said and done. Which is understandable considering they are custom making it.
Finding 3: Techno CNC offers a 24x30x16
This one is for sure a heavy duty machine it’s a little less working space on the x slide, but I could work with that. It’s about double the price of the K2CNC which isn’t too appealing to me. But I know they’re good machines, and I have a guy that’s local to work with.
Finding 4: Ice Bulldog Pro 20x40x16
I don’t have much information on this one other than it has the measurements that would work. I sent a request for a quote, but my guess is its going to be more than I want to spend as well.
Finding 5: Everyone else
It seems everyone else either offers a 6 inch z or can’t upgrade to a deeper z. If they can they are usually very large machines and wouldn’t even fit in my shop and have price tags that are completely out of my range.
So is this truly the end of the internet when it comes to deep z machines? In a perfect world CAMaster would have an upgrade option for a 12 inch z… Man that would be nice.
If anyone knows of a company that provides such a machine please post it or give me your insight and or guidance.
