It depends on how much you have to spend. Even in China there are differences in quality based on price.

What is a manufacturing degree?
The precision of the movement for a 20 pitch rack and pinion system doesn't change with the ratio of the gearing. The efficiency of the motor changes but I don't think that's what you're asking. You...
I'm sure this is just spam but you can create a forum all by yourself. And then you and the other one guy who bought one of these can talk to each other through it.
If you are worried about getting sued the answer is
No matter what you do or what you say to the buyer
No matter how STUPID the buyer had to be to hurt himself
Even if the buyer violated the law...
There's a shock, something doesn't work which you got from AT and CNC4PC and you have to go to a forum for help.
I assume you have SOME skill when it comes to fabrication since you are going to use the machine for fabricating. I would suggest you build your base out of tubular steel welded together. It is VERY...
It doesn't really matter who you buy it from, they all come from china with no support so you might as well buy it directly. If you want someone to sue if it doesn't show up that will cost you extra....
Gee, lousy support from china?
I have one with the chinese pneumatic drawbar. It dropped right into the BT30 spindle mount of my Syil linear x6. Everything is fine but the power required seems to be excessive, especially when...
There is a cup on the side of my new pdb that I don't know what to do with. It might be an oiler. The picture I have of one being used looks like it has oil in it.
Any help would be appreciated.
Since tools in a turret have to approach the workpiece from one angle, wouldn't tools have specialized shapes? For instance, you would have to make 2 tools one for facing and one for turning on a...
This is on a new machine 11X26? something from Grizzly. After center drilling I try to drill with a small bit in a tapered chuck in MT3 tailstock. The barrel keeps turning, it grabs the screw from my...
Most of the chinese ball screw kits are listed and have drawings at https://www.automationtechnologiesinc.com/
Forget anything from china. The only way, at this point, china is going to save you money on a router is if they are selling crap. US people are selling good reliable products at just above cut-rate...
You should be able to see what the other builders are using just by looking at their descriptions. CNC Mill Router Engrave 24"X24" | eBay
is a good example from a reputable builder. (I have no...
I just started the same one but it's a 4003 and I am replacing the motor and eliminating the gear train. 3 hp ac with VFD directly coupled with the spindle. I am still thinking about the cnc portion....
You should buy the best mill you can start with. If the budget max is 3k you should only spend 1.5k on the machine. The electronics for any machine which is going to do steel quickly is another 1k...
I bought a spectrum 875 with machine torch and occasionally need to cut something small and simple. Is there an easy way to use or convert the machine torch so it can be hand held?

I have a few questions. It looks like you have rails going from left to right in the area that, I guess, you are going to run your plasma cutter. Are you going to use a vacuum table or water table?...
For that thin of tubing I would use a manual tube cutter like
RIDGID 151 Tubing Cutter-31632 - The Home Depot
If you have many tubes to cut, then let me know. I think I've seen an automated one...
I would file as little of the gib as necessary.
When you first took it out of the crate, did it work? I assume you're talking about the spindle axis. Have you made any changes to the head?
Two of the best site for 0704 info include a belt drive
G0704 Belt Drive DVDROM
.01 mm is 0.000393". Less than 4 tenths. I'd be willing to bet your bed isn't precise to within 4 tenths over half of it's length. I have 2 denford oracs right now I am converting to mach4 and I will...
Metalworking milling machine?
You have to give us something to work with. When you only specify one dimension (18") on a lathe, that usually means the swing. A lathe with an 18" swing is massive. I am assuming you mean the z axis...
Just make sure you can return them when they show up damaged. A large percentage of tubes not in machines are damaged at the factory :-) or shipping.
If, as you say, "The machine will have only small forces", then the base of the guide will support the working force and the only requirement will be to mount the guide straight and level. If the...
You've given it a fair try. Forget it. Go to work for someone and earn enough money to buy the machine you can't build. You don't have the nature or nurture to do this kind of work. What did you last...
