How simple can CNC Machining get?
Thinking about this more there are two design philosophies that may illustrate your thinking vs some machinists here. It’s Parametric Modelling vs Direct Modelling. With parametric, we define features with specific dimensions, build our code off of that and edit the code (in some form). Code... -
How simple can CNC Machining get?
You’re being a whiny little shit. Which is okay, I was a young whiny shit once. My wife would argue sometimes still am. This forum is for professionals. The people who choose to deal with an exceedingly difficult trade and get paid (generally speaking) poorly for it. 15 years ago this forum... -
Leadwell MCV1300 Fanuc OM Tool Changer Issues
As far as I can tell there are no limit switches for Carousel Right or Left. When I do a “tool change”, it hangs and I can manually close the Carousel Down limit switch and it will index to the requested pot. I believe it’s something to do with the Carousel Right (toward spindle) command. I...- RC Mech

Advice for a lathe for a makerspace
His selection is not narrowed to new machines on the basis of being adverse to rebuild/restore. There are always options to purchase a used machine that doesn’t require work. Plenty of solid lathes on the used market. Now if he’s limited by policy like some High School shop classes are to...- RC Mech

Powering a cnc
There’s a loss in terminology here. A CNC lathe will have a VFD in the spindle drive. Can a 3 phase CNC lathe run on 100 A single phase? Sure, but you either need a static or rotary phase converter. There will be an amperage loss here- you will always need more single phase current than... -
Powering a cnc
The answer is no. Any speak of “industrial” and single phase, for a CNC lathe, the answer is no. And no, I do not consider a Haas TL1 an industrial machine. -
Leadwell MCV1300 Fanuc OM Tool Changer Issues
Dan, The ATC indicator is lit, yes. Spindle orient works both with the button on the panel and with an M19 command. If I call a tool in MDI, nothing happens. When I manually close the limit switch for carousel DOWN position (while it remains UP), the carousel will index to the called T#. I...- RC Mech

TIlt to rotary table
Had an old boss make a huge sine plate out of two scrap mold bases. It was awesome, nearly 30” x 40” or so. Plate will only be as accurate as your ability to make the pivot and reference diameter square and consistent on centre distances. And the OD of the ref diameter/plate base.- RC Mech

Additive Manufacturing in stamping dies
Poor compressive strength, cannot be HT, not economical and doesn’t scale well. Last point may be moot as T&D is a specialty not known for economies of scale. But in short, SLS isn’t suitable for making anything but low pressure tid bits for detail while the remaining components (shoes, bases...- RC Mech

Leadwell MCV1300 Fanuc OM Tool Changer Issues
Dan thank you. I can step through all the motions on the ATC via M code. I was making a list of what worked when I saw your reply- moving the carousel to the spindle or away were the codes I couldn’t figure out. So yes, all functions of the ATC work per the M codes. That would mean the relays...- RC Mech

Chinese lathe good enough for my needs?
Yes it’s bonded both through the service and independently to the machine casting. 600 volts is no joke. -
Chinese lathe good enough for my needs?
The OP directly mentioned “Chinese” lathe. I don’t think any of the responses have dissuaded him on the basis of country of origin. The bench lathe above is an objectively poor design and execution. I’ve got a Bochi lathe, 20” over the cross-slide, 80” centres. Something like 38” in the gap... -

Did you mean “Campat”? I found Campat in Plano, Texas but the website throws a malicious note as no one’s updated the security cert in 3 years.- RC Mech

Leadwell MCV1300 Fanuc OM Tool Changer Issues
Have a 1992 Leadwell Fanuc OM, tool changer hung up and will not cycle now. The problem is I cannot remember all the steps to reset the ATC. In MDI mode: PWE = 1, scroll to Diag. D0441, make sure this number is the current spindle Tool #. Diag. D0440 is the carousel capacity, 0020. Change...- RC Mech
