Haha! I knew Ramond was going to get it after reading his boss's post. Congratulations Ramond!

[@eXlem18]

working with plastic you truly have to think outside the box, I work in a company that mainly make plastic parts in Europe. I also work on 2 spindle lathes and there's no same work. Working with coolant isn't good most the time, high pressure air is better for outside cutting and most of the time you don't have to machine the contour from outside of your stock material, you can save machining time by starting from your chuck and then comming out. But it's better to work with collets. Also the Citizen vibrating feature is super useful for plastic, look it up it's worth your time, if someone is curious.

[@brandons9138]

Oh hell yes!! LFV is a game changer for plastics. We use it as often as we can on our Swiss machines. It's a life saver for eliminating chip wrap.

[@gt4654]

New machinist here. Now learning the craft. Hope some day I will work close to machines like the ones that you have there. You are truly blessed.

[@jonnyhifi]

Even with a small home cnc mill - I’m learning stuff from you guys ! It had never occurred to me that you could program the machine to clear the burr away. Awesome. Ty for your content.

[@jasondk5127]

Congratulations Raymond! Those are a great set of calipers!

[@MitutoyoAmerica]

Congratulations Ramond! Hope you love the new caliper.

[@PatriarchaClavaPenguinInsula]

About chips sticking to the tool, Haas made a video about it. Apparently you can back out the drill, reverse the spindle and dwell of a second and that should eject the ships.

[@brandons9138]

That work extremely well if you have a coolant nozzle pointed directly at the tool as well. We use that technique in my shop all the time.

[@barrysetzer]

Great video Travis. Love the chip removal technique on the OD finish pass.

[@williamk1452]

Machining plastic is all I want to do. I love it. Tool wear is minimal, speeds and feeds are lightning and my hands stay clean!!!!!! While I have medical on the lathe and aerospace on the vmc, I'm making a fish tank! Oh yeah, there is no money in plastics and it's really hard to do. Stay away;)

[@sbeprecisionproducts6729]

Easy there man. Lots of plastics are abrasive and will eat up carbide, and wait until you get a job where the plastics are filled with graphite or other materials. Acetal is the best for machining. Nylon eats carbide like no tomorrow. I use PCD.

[@brandons9138]

You'd be surprised at what polycarbonate will do to carbide. We do a shit load of plastic at my shop and make a shit load of money doing it. We ship 6000-12000 parts a week to our medical customer. We buy and machine enough polycarbonate on a monthly basis, that when we buy material, we change the price for everybody west of the Rockies.

[@Anthony-uz5tj]

dave d sounds like an awesome boss i wish i worked for em

[@BrianHollihan]

Same here, you don't find people like that too often anymore 🤙

[@vincentbernolin1943]

The tips to control the chips’are very clever. Thanks.

[@opendstudio7141]

That was an innovative use of a deburr tool. Simulating the process mentally, think it took a few attempts to get it dialed in. 👍🏼

[@kyle_in_tex8422]

LOL, even though I didn't win the calipers.....I still think this is a great video because it shows just some of the tricks machinists learn over their careers.

[@hithere3609]

#VeryCool! #ThankYou! for keeping it positive. This video shows what is possible if we all try to get the best grades in school. Please in the next video give a shout out for all those who are coming up. By shooting out "YA HOOOOO!"

[@maxnex7676]

Combining the small drill bit with a debur tool, now that would save time .

[@tompass8446]

for the outside you can use a wiper insert to maintain high feed while achieving a nice surface finish and save yourself a tool change

[@benkenny3220]

I'm not sure about turning plastic, but I've gotten good results milling sides of plastic dry at 600SFM... It seems to kinda melt the plastic and give it a glossyish finish. Never drill or tap dry though, unless maybe there's time. I also got good results milling some gummy steel dry at 400 and there was somehow less deflection. That same part you can turn it at 550, bury the radius of the 431 (Been so long don't remember the tooling that well) on the finishing pass for axial at about .0035IPR. Get something like a 64 finish which is phenomenal for that material and how it's ran on other machines.

[@marktatara9545]

Awesome job!

[@rcandcnc9684]

Cool video, is a tool load monitor required for lights out machining or is it common to do it without one?

That deburring tool is genius. Wonder if a similar one exists for metal.

[@mehmettemel8725]

Recently machined some UHDPE and hated the stuff,somehow a fine stringy bit made it's way behind chuck spindle and labyrinth seal.Spent more time trying to remove it than it took to machine the parts.

[@michaelcarey5981]

Curious as to the size and tolerance of the holes in that part

[@tarehjernetarehjerne4082]

How does that deburring tool work? Would it not drastically overshoot the holes?

[@shadowdsfire]

It's called burraway and made by Cogsdill. We've tried it for machining similar bushings but in steel and they didn't work very well for us. The holes were too big compared to the OD/ID diameters and so the deburring was really oval and inconsistant.

[@dan3718]

We use them where I work and they work really well for us but we mainly use them in hand drills so you can stop spinning and push it through the backside of the hole. The tension screw is how I am guessing they are stopping it from opening up the ID of the hole. You can loosen the tension so much that as soon as pressure is applied it retracts the blade in the shank and no cutting edge is exposed.

[@scottwatrous]

We use 'em in aluminum for riveting aircraft sheet together. They don't remove enough material on the way thru that it affects the rivet tolerance, if used correctly. However they get expensive when the noobie runs one through a part that had two bad holes that intersected (trying to knock off the burrs so the sheet could still lay flat) and the deburr flap 'snags' in that gap and the sudden force shatters the drill shank. It's me. I'm the noobie.

[@willyharris4199]

We use them in aluminium, works fine

[@mtlfpv]

What way do you do the debur pass on the OD finishing? Do you just lift the tool up a bit before feeding back across?

[@NaturallySelected]

Doesn't that deburr tool affect the size of the hole?

[@nathanthomas8184]

PET-P is GREAT to machine some variables to consider BUT have used a $20 vacuum behind tool so waste escape thru hose & into a waste BIN, Titan have a Joke What's the only difference between a Harley & a Hoover ?? Location of the DIRTBAG T TEAM keep on BOOMING on

[@ryanjordan7113]

I’ve worked with that same tool and we fed through with a clocked spindle. It doesn’t effect hole size?

[@adrianprzybyek5758]

Wise guy

[@Angel-gn4iy]

Can this be done on a mill ?

[@timmontano8792]

What's the name of that spring loaded deburring tool you used on those plastic holes? Do they make these same types of deburring tools that will work on aluminum or steel? I work on air rifle projects that require holes to be drilled through the receiver walls and it's incredibly difficult to deburr the inside edges of those holes. This tool looks like it would be just the ticket. Without deburring those inside hole edges the O-Rings that get slid into the receivers can get shredded.

[@IkarimTheCreature]

These deburring tools are known as clothspin-style tools, cogsdill is the major manufacturer of them

[@paulpelletier9422]

a lot of thin walled plastics tend to "pop" after part off, wondering how you're dealing with this. maybe the tolerance is wide enough to not matter, or if this material is less prone to that

[@tomnomnomnom1317]

PET is pretty consistent as far as plastic goes. Doesn’t tend to move much besides temperature changes

[@TommiHonkonen]

Would that deburr tool work for metal?

[@TITANSofCNC]

Yes

[@TommiHonkonen]

@@TITANSofCNC Nice, ill have to keep that in mind

[@dan3718]

We use them on aluminum and stainless. The tension screw is key for what material you are using them for, the harder the material the tighter the tension and the softer the material the lighter the tension screw.

Hey Does your machine support gear skiving?

[@Deetrex]

Where can i finde the deburr tool ?

[@ernest6980]

Bro I hated the burrs the key are the correct tooling and speeds and feed also high pressure coolant

[@rhindy6846]

How are you guys able to stop the plastic expanding because with nylon I was always teached that it can absorb coolant thus making tolerances hard to hit with coolant?

[@sbeprecisionproducts6729]

Air blast usually works well in those situations.

We turn PA6 parts that looks like T in it´s cross-section view 170/160 for 5mm then 175/155 for 5mm, relatively thin part.... I measure them before putting it out of the fixture, they´ll bend like a hell and after you open the jaws you´ll have hard time to measure them correctly... for most of my plastic parts I say if they´re on spot in machine, they´ll be right on the spot when they´ll mount them into their place...

Why not injection molding for plastic if large no. Of parts

[@trevor6512]

how does the whole chamfering tool not make the whole oversize when it comesback out?

I think that part is worth it's weight in Gold.

[@ТаняКруг-у2п]

I see you, like everyone else, have a problem that the chips remain on the drill. How do you solve it?

[@jackflash6377]

Every four holes I do a pause and reverse the spindle for 1 second, this always works to remove any built up chips. I'm drilling 12 holes at 5mm diameter going 14mm deep into Delrin. no peck.
