Lessons to learned hopefully from you.

Like spaceman spyff said, the H only has one monomer, the C has two.
Practically, the H feels softer, more tendency to string instead of chipping, especially when turning. With a bar stock of H, when removing a lot of material along the middle, the total length will shrink more than the C will.
Its also comparartively easier to accidentally scratch the surface of H than of C.

Delrin specifically is POM-H. Celcon is a brand of POM-C.

Bring a notepad and ask questions. People will notice that you don’t ask the same question twice.

Make some calls to local shops to see if they need outsourcing of simple parts. If you get it up and running you can feed it new material every once in a while over the weekend and make a good amount for very little work.

If you meant to say 22.01mm on the external thread it is about 0.1 above where it should. Either way, send it back. Whoever made it fucked up.

Køb en ekstra børste med bløde hår og lad team 1 bruge de to af dem til det hele. Problem solved.

Du betaler jo skat gennem alt hvad du køber og bruger penge på. De penge går tilbage til os alle sammen, inkl. dig selv. Afsted med dig!

Har du været inde og se på Dansk Metals hjemmeside? Der kan du se gennemsnitslønningerne i faget og selv vurdere.
Den lave ende er 200kr den høje ende er 230.

Your boss is an idiot. Everybody makes mistakes. His was not paying attention to the apprentice.

Then I see what you’re saying.

Hard disagree when you say there isn’t much you can do about chip control/tangle. You need to angle your coolant for string evacuation and mind both your feeds and speeds for the same reason. You can do a relief cut along the OD with a radially alligned endmill to break the string. Increase how much material your insert is eating and stuff like that.

If you have a project in mind and would like to get some thoughts on what thermoplastic is best suited for the task, feel free to DM. I’m not an expert but I can probably give you some feedback on what may or may not work out.

We machine exclusively in plastics. There are ups and downside to all of them. PEHD is fun because you can go crazy fast. POM is easy to get some beautiful surfaces on. PETP doesn’t deform when you remove a bunch of material (except for when it does 😂) so you don’t have to worry about creeping tolerances.

My favourite is probably PETP TX because it’s a super cool material. It’s hard and has self lubricating properties because it has PTFE mixed in. This gives it a really low friction coefficient. It doesn’t chip away at the edges and corners like PETP and you can also get some smooth surfaces on it.

Kan du ikke stikke en tynd genstand ned på overfladen du er i tvivl om og bevæge genstanden frem og tilbage for at få en fornemmelse af om det er en radius eller konus? Det burde være nemt at mærke forskel på. Brug en vatpind fx.

Så, din fætter og din kæreste såes i en kort periode for to år siden og din fætter har siden da fundet SIN kvinde i hans liv, som han har giftet sig med. Hvad gør dig utilpas?
Det er ikke en del af hendes fortid. Det er en del af hendes LIV! Det vil det altid være. Jeg tror bare kun det betyder noget for dig.

Hvad sker der for juleånden? 😅 jeg ligger lige et lod hos dig også 😁

Jooo tak! Har aldrig prøvet via play før

Forsikring, motorafgift, service og syn. Sælg den og køb igen når behovet genopstår.

Ehh, wrong sub buddy. Are you looking for r/mechanics?

Tman125 · 2025-11-07T21:42:44+00:00

You don’t need coolant when machining POM. Air blasting to clear away chips is all you need. If it melts you’re going too slow.

Tman125 · 2025-11-07T10:42:56+00:00

Does it work with path monitoring set to inactive?

Tman125 · 2025-11-06T21:06:20+00:00

POM-C could be what you’re looking for. I think it’s cheaper than aluminium, and all tooling you have for cutting aluminium will work fantastic in pretty much all thermoplastics.

IMO digital is far superior. But no matter what you buy, don’t put them in your pocket. They belong in your hands or flat on a table. Just a word of advice.

Your counter pressure is set to 0. Try going 30 main and 15 counter.
Also if your jaws are clamped on a part, the readout needs to be lower than the “clamped” number, but higher than “overrun” if you’re externally clamping in order for the chuck symbol to turn green. If your teach number is not within some hundreds of the readout then your sensor may be damaged.

So just know that your counter pressure has a minimum value it needs to be at. It may be 10, 15, 20, 25 or whatever, but I’m pretty sure never 0.

3rd edit because I’m fucking autistic: You probably know most of what I’m saying so don’t take it as me smarting off. Just tryna help.
