granite is much cheaper compared to having steel ground at a company, you know those prices well. It's completely stress free too, having been there for millions of years. Sounds to me like it's...
Electrical people hate this type of diagrams, prepare to face their wraith!
Why wouldn't he want granite, its already flat. Big problem gone from the get go. It's plenty stiff for the job.
On the front same gap, the gap isn't the problem though, 20mm is good enough for small chips and coolant only pools slightly on flat surfaces, the problem is this approach to steel table + chip...
Yes, but I don't like it very much. There's not enough space between the components to fit the tray in any other way. The gap is 20mm. This approach is flawed.
Managed to get something remotely working. Have to say I am not a fan of it. There's something about it I don't like though I just might be too picky. This setup allows me to separate chips and...
Unsurprisingly the steel tube under table is proving to be a major headache. Nothing wants to align nicely, if the structure is good to support the weight, can't make the sheet metal covers for muck...
would you weld or braze a steel table? The welds are localized at the joints only so I assume the deformation is minimal in regards to the whole structure? Or is it significant enough to braze them...
Here's what the final machine will look like.
I had to abandon building it on a 1200x800x120mm granite plate. The weight of the thing was 350kg and I do not want to risk having it brake in half...
I wouldn't dabble with welding, if it distorts and it will you'd have to send everything to stress relief and machining, that's over your budget. T's and H's construction steel are very bad against...
Do you plan to do everything via math or gut feeling?
Do you have access to "friend" machining so you don't have to pay for it?
I'm with you on that. QoL is definitely something that is lacking in diy machines and with the M1 you also have a very clean way cover assembly that's very straightforward to implement. You basically...
HSM is usually 12000 RPM and your DOC and torque determine how much of the flute length you can engage. Otherwise the other option is datron style/dental milling. You thinking of the 3.7kW metal...
spindle box or headstock is the assembly that mounts to the X or Z carriage and houses the spindle, so in your case the spindle mount+plate.
The weak point is the plate. Usually people reinforce...
All of them should be sufficient for light work, but in all honesty all of them are weak.
What kind of equipment have you got to work with?
Can you process steel?
Best and cheapest would be...
So I guess the proper way to go about this is have a standalone pc for the machine and look into some form of remote access from the main pc. Well my laptop needed an upgrade anyway so I guess...
How exactly does the process look like with ESS? I mean from cam to machining? I'd ideally want to compile code and send it to the machine via a long cable and continue doing other intensive stuff on...
electronics huh? I guess it's a question I'm gonna have to tackle at some point. I'm tarded when it comes to EE, been to university twice and failed it just the same, one day I solve the questions...
Here's a fully welded frame, the z axis assembly is a stiff one, spindle box could be a little bigger but overall it's a good design(spindle box is held on the sides), this type is stiffer than what...
for 2 grand I'd want a ballscrew, linear rails(not round ones) and maybe even closed loop steppers.
Not interested in building it yourself? you can do something better with extrusions some...
I like the removal of side walls and the gantry is going in the right direction, keep at it. I'm confused why you want to enclose your granite plate inside a uhpc cast. Is it a replacement for a t...
Hey Pete,
Ever had a customer request biocompatible materials in one of your boat jobs? Things like non-toxic plastics and adhesives with very low outgassing specs?
Thinking of building a...
We're all limited by our budgets Craig and even if I wasn't I'm not sure I wanna pay more then 5k for any type of a machine and I have big requirements mind you. Doing the thing properly, either cold...
The z axis will collide with the side walls if you make it big and rigid. So you will either have to make the bed wider or have a smaller work area or have a weak z axis
You don't have enough space between the sides to make a rigid z axis and not loose some of the work area or making the bed wider.
Hey Peter,
I've been thinking on how to additionally stabilize the rails on the surface plate. Came up with a vice style micro clamp for each bolt, from each side. I'm wondering if it's more...
I'd go away with the disc toolholder and do a chain magazine toolholder instead, you wont need to do any cutouts because it will fit right in between the gantry and the bed. It can be as simple as 2...
try uploading your part to xometry, I couldn't find a cheaper machining and I've been looking for over 2 years now.
