Hey I’m a fab guy and I have a 1/4 in drill bit that works awesome on hardened steel and I’m looking to get more I just don’t know what kind of bit it is I would appreciate the help

Needed a little extra support on this long thin part that had a perfect step to clamp on, and this step clamp was in reach so I used it. It’s almost .250” off the fixture plate.

Should I correct his spelling?

Can anyone recommend a supplier other than MSC or McMaster for the solid carbide version of this end mill? Or possibly an alternative tool?
Thank you

Tool maker for an aerospace company and I think this every time i finish a fixture.

A doctor, a lawyer, and an engineer were waiting to be guillotined by the Taliban.

They tested it by chopping off the head of a goat. They dragged over the doctor. "Do you have anything to say?" "Why kill me? I'm a doctor. I can treat your sick and injured." "off with his head!" shouted the mullah. The crowd roared. The doctor was stuffed into postition, the executioner jerked the lanyard and - nothing heppened. They took the doctor out and tried it on a goat. Chop! It worked perfectly.

A big cry went up from the crowd. "Spare the doctor. It is the will of God!" And the doctor was freed.

Next they dragged up the lawyer. "'I'm a lawyer. I can represent your cause before the world court..." he was stuffed into the guillotine... the lanyard... nothing happened...the goat... the crowd "..the will of God" and the lawyer was freed.

Next they dragged up the engineer. He said: "There's a burr that stops the latch lever every other pull. Gimme a file and I could dress it off."

I was cleaning out chips in our Haas VF2 when I noticed the hose had very little pressure. I took the nozzle off and saw what looked like a rubber band wrapped around the ball valve inside the hose nozzle. I turned the coolant on without the nozzle on and all of this came out, meaning it had to come from the tank or the pump but I just can’t imagine where. Has anyone seen this before?

Sup yall, ive recently took a peep at some of the tuition my job offers that can go to completing different certificates and degrees, id like to dip my feet into the Cnc machining word and am wondering which of the options would have a better route to go, and which would just be redundant or not really helpful for getting Into this field. The options are these pictured, any advice is welcomed.

Edit: Here's the classes associated with each one

I also realized some i missed the window to apply so these are the ones remaining.

Industrial Manufacturing Essentials Micro

-foundations of industrial and manufacturing -fundamentals of hydraulics and pneumatics -intro to industrial electronics -PLC & CNC in industrial manufacturing

Additive Manufacturing Undergrad

-engineering graphics and design -GD&T -advanced machining -additive manufacturing process -advanced additive manufacturing

Hello everyone, I need some help with my mental state in the trade right now. I’ve been working at an aerospace shop for around a year now. Is my first job in the trade, I knew absolutely nothing going in. For the last 2-3 weeks I was put on a job with 4 plates for a weldment. It was one of my first jobs programming on my own, and doing it all alone. I got all of the plates done, they were all in spec and then my supervisor comes to me with a rev change on all 4 plates. I get them all re-programmed, get 2 of 4 done and on the 3rd plate I absolutely torch it and mistype my comp for a countersink. Crashed right into the part. I was in a groove and was trying to get the countersinks done before my shift ended.

It’s absolutely tearing me up. I’m in a weird mental spot. Part of my mind is telling me to ditch the trade, I’m young enough I wouldn’t have an issue learning anything else. Just in a very negative headspace and need someone to talk to. Thank you.

The lathe is a Colchester Bantam and the Mill is an Adcock & Shipley model 0. The were originally purchased as an auction lot from a factory that was closing down and may have included parts that were thrown in that didn't match the machines just to get rid of them.

A bolt on hinged clamp for the sine table at work so I don't have to use toe clamps.

Mostly a woodworker but the machine shop supervisor lets me play around sometimes. Did some manual machining on the lathe. The parting cuts on the screws all have this spiral pattern. I'll be keeping it.

Hello everyone,

I’m not a machinist. But I’ve been tasked with making some soft jaws for a square piece of stock. We need to put a tight tolerance bore into the part and it will be easier to hold on the lathe. The stock will be finished machined so it isn’t rough stock. The part would be sitting 2 inches into the jaws and is about 3.5 inches tall.

Will these work for that? Will they be accurate enough for a .008” True Position tolerance? Is there anything I should be aware of and change before we make them?

Thanks in advance!

Hello everyone
I have been working as a machine setter for one year and as a CNC programmer for a year and a half. Since I’m based in Bulgaria and local salaries are quite low, I am planning to move abroad once my current contract ends in a year.
My question is: Which countries currently offer the best opportunities, salaries, and working conditions for CNC programmers and setters

Good morning everyone. I'm curious how chambers for wwii era Artillery were cut. Does anyone know? Specifically the 37x223r cartridge, which is 37mm x 223mm rimmed.

I have chambered before, but on the little guys I use a finish reamer to size and lots of oil.

How was it done back in the 30s and 40s?

We have this Main shaft used on a liquifier that every so often has to be completely replaced because the bearingraces are corroded tightly to the shafts matingsurface so that we have to anglegrind them Off.

Bearingraces are made out of cast Iron from what i can Tell, the shaft is 42CrMoV4 QT.

Im Not the maintainers but i think they tried both with and without Grease between the surfaces and it didnt make a difference.

The fit is a Clearance fit with 0,01-0,015mm Clearance (Diameter 36,53mm).

I thought it might be the Same Type of wear that you Sometimes See on milling toolholders where there is too much Play between the toolholder shank and the spindle taper and they bang into each other when milling but im Not Sure?

Maybe some of you got better ideas.

Unfortunately I think I'm out guys. I've been working for a small machine shop for the last year and a half. I got hired with no experience, but I took on pretty quick, I mostly ran manual lathe and some 2axis . Recently my owners got a new lathe and a 3axis that was supposed to be my specialty ( everyone else in the shop has 0 computer skills) i took to the cam software and everything very well but we never got the work for the machine. Long story short I got laid off with an " I'll let you come back in when we get the work" and I'm not going to be essentially a free lance programmer for what they pay and I'm not qualified enough to realistically apply for another job. It's been fun though everyone. Best of luck

I made a batch of nice crafts on my 3-axis mill with multiple setups. As machinists, what do you guys make when your machines are idle?

Do you know of any software that could turn g-code into a CAD STEP file? Is there anything like it?

I made the terrible decision of buying a used APSX injection molding machine for a side work, and after 2 years of owning it, I haven't found any jobs for it. I'm considering selling it at a loss. What would you do in my position? Can anyone point me in the right direction?
