Jazeker, al weer een hele tijd, maar sinds dit jaar met de CCR. X-CCR om precies te zijn 🙂

I believe about 6 days. It could be a day more, but we also had some very nice sunny days, so I am not going to complain about the rain 🙂

Those are Gerardi vises.

@@eggbird01 sweet. Have you used the straight jaw ones before instead of the pull down ones? Been Looking at getting some with the straight Jaws so I can cut soft Jaws on them aswell.

Dank je, alleen iets te veel close up bij de zeepaardjes en bij de pijlinktvis was het ff onhandig er lag een kei in de pad waardoor ik wat teveel beweging had. Maar al met al heel erg tevreden, het was mijn eerste duik met een mooie videolamp er op. Er komt nog een 2de lamp bij, maar die staat nog in bestelling bij Onderwaterhuis 🙂

The cutting speed is determined by the manufacturer and for specific materials and inserts. a Vc of 300M/min is quite high, but in this case well within the values recommended by the manufacturer.

the insert is from "Fette tools" it's called the twincut-feed

It's a direct drive 12000rpm spindle, the standard spindle on a Haas VF2SS model.

Egbert de Pauw thanks for your kind response

It works ;-)

Yes I know... it's bad, the feed was too low on the drill. We do a lot of single piece runs and sometimes we have to adjust the feed and or speed. On parts that we do in series we fine tune everything, but for a single piece it sometimes happens that some value is off.

For me the part it is just perfect, the surface finishes are impressive and the feed and speed are leaving a impressive mirror finish. Nice job. The CAM is HSM?

Thanks ! Yes, we use Inventor HSM, it's the same as HSM in Fusion or Solidworks

We don't have coolant through the spindle and that's something we regret not having. So if I would one again I would definitely take the coolant through the spindle option and also the airblast option.

Egbert de Pauw You are right but That option is 5.5K euro plus 2K filtration -system its expensive, and time you save is only 30 % , Im not sure do I need it.I can drill 30% slower and sawe money for 3d CAD

If you drill a lot of stainless then you do need it, steel and aluminium, you don't but in that case, it's just a time saver and your drills last longer.

We use aluminium tools, so sharp uncoated carbide mills. If you do a lot of plastics/nylon etc the best option is uncoated 1 or 2 flute end mills. This is glass fiber reinforced Nylon PA6/6. In normal Nylon, the problem can occur that the material starts melting and then the surface finish will be terrible. but other than that milling plastics isn't difficult.

True, probably would have fine tuned the code, but this was a rush job, got the order and we had to start milling right away.

Inventor HSM, but that's almost the same :-)

try 220 spm and 1.0 fpt rough. 220, 0,6 fpt finnish. i allways get great result for me personally with a 63 mm face mill with 5 cutting inserts.

+ipadize We welded a bar underneath the workpiece. It was too big for the vise.

+the russian machinists That's probably true, but you use the machines you have, and actually these parts had some features we did on the lathe, and the guy on the lathe (conventional lathe) couldn't keep up with the mill. we had to do a lot of them in a short notice and we were using both machines to get the job done.

+Mischa de Bruijn zit normaal tussen de 220 en 260 Vc in constructiestaal met deze frezen en 20% Ae met een Ap van Max 2xD en dat loopt goed op de machine ook een behoorlijke standtijd van de frees, maar het bijzondere is dat deze frees "goedkoop" is, een instaplijn van SCT die op papier hier helemaal niet bij in de buurt kan komen en dat klopt ook als we hem in een spantanghouder zetten, maar met de hydro houder ehmmmm geen probleem :-)

+Mischa de Bruijn Dit was gefilmd met een Gopro Hero3+ camera

I think you are right. It was the SS Laurentic, sunk on 25th January, 1917. My great uncle was onboard as a fireman and died of exposure in a lifeboat.
