r/CNCmachining

While I’m not a machinist, I’ve worked at several places that also did that. Including my current job. At my current job, that is the wordy coolant smell I’ve ever experienced. It’s nearly enough to make a billy goat puke.
No, the coolant never gets replaced, only added to. Yeah, I suspect that is the problem. I believe it’s Blaser, and it’s water based. But I also understand that coolant is hazardous waste, and costs a lot of money to get rid of, so shops tend not to. While none of our machines smell particularly pleasant, our newest machine is by far away the worst offender. It’s a machine that was bought at the tail end of last year. It gets used regularly, but not constantly. If it’s just sitting there idle, no smell. The second you turn it on though, holy shit. I believe there has been at least two people that have tried to figure this problem out, one of them being the guy who sells the coolant mix.

What is technically the correct course of action to deal with this issue?

There is a community college course here in my city that is 6 quarters long, and has a night time course option. I am a caretaker now and am thinking of keeping my job during school and just dialing back my hours to like 6 hours a day or less, idk. I have a flexible job. But how much homework is there. I know it's full time and I've done some college in the past. Wondering if I can make it work. Like am I being realistic or not. Also I make 24 an hour now, and am considering that maybe this isn't the career for me if I'll likely be stuck in a dead end job not really being able to go up from there. Anyone have any advice. Also I love physical jobs, worked for ups and amazon and took an introduction to trades class before. Lol idk. I just want to make more money.

I was considering purchasing an old, cheap Cnc machine to fix. I want to make car parts, however I’m new and know nothing about Cnc machines or machine. What machines should I look at to make just about anything? Where should I buy and what prices will I be looking at? Cheapest route? Plz excuse my ignorance.

Hi,
I’m looking for a new CNC turning center to replace my almost 20-year-old DMG NEF 400.
My main requirements are:
Siemens control
Y-axis
Driven tools
52–65 mm bar capacity
Good spindle power and torque
Solid, reliable and reasonably operator-friendly

I regularly use indexable insert drills** **up to 34mm, both in aluminium and steel, so spindle torque and rigidity are quite important to me.
I’m particularly interested in the DMG Mori CLX 350, but its spindle torque is roughly half that of my current NEF 400 and the clx 450 might be a little bit to big and expensive . I’m wondering how noticeable this is in real-world machining, especially with larger drills and heavier turning.
What are your experiences with the CLX 350?
I’d also appreciate recommendations and experiences with other models and manufacturers such as DMG Mori CTX machines or the new EMCO Universalturn 50 or any other manufacturer.
Which machines would you recommend for good value, rigidity, spindle performance and ease of use for the next 20 years ? I’m looking for a solid machine for general job-shop work without going crazy on price.
Thanks!

Hi everyone!

I’m a freelance CNC Designer with 4 years of remote experience specializing in 2D and 3D modeling using ArtCAM. Because I also operate my own 8x4 foot CNC router for custom designs, I know how to deliver practical, production-ready toolpaths that run smoothly on the shop floor.

I can start immediately to help offload your design work. I would be glad to show you examples of my past work directly or do a quick trial design so you can verify my skills.

Feel free to send me a DM if you're looking for reliable remote help!
