Andrew needs a raise.

I like working with guys like Andrew who keep the standards up. Good job Andrew.

It all starts with good coolant. The coolant literally touches everything.. Your part, your tools, your machine, YOU! Good quality, well maintained coolant enhances/protects everything it touches.

I vote for free beer for Andrew

This is gold. Hands down, nothing better than this video out there (for coolant maintenance on CNC/VMC machines). Thanks HAAS.

I have an issue with how you calculate top-up solution. You are doing it in a roundabout way that makes it easier to make mistake, and this is definitely not the way you want to teach to someone who needs help with such a task. I would advice it to be done as following: 1) Calculate target volumes of water and concentrate separately. We need 55 gallons of mixture at 7% concentration, so we need 55*0.07=3.85 gallons of concentrate and 55*0.93=51.15 gallons of water. (This part can be done once per coolant type change and written down in service log.) 2) Calculate current volumes of water and concentrate in the sump: 44*0.04=1.76 gallons of concentrate and 44*0.96=42.24 gallons of water. 3) Subtract current numbers from target numbers to get volumes of concentrate and water to mix in: 3.85-1.76=2.09 gallons of concentrate and 51.15-42.24=8.91 gallons of water.

My lil' buckets graduated too. I was so proud. We had a huge party!

Starring Andrew. And THE Announcer. A riveting production. The chase scene was exceptionally well done. Certainly will be up for an Academy Award. I will put this in my reference archive for review; I learned a lot. Thank you.

Thank you for all the work that went into making this video! Somehow, somewhere, you cheered up somebody's old black heart!

Wow, such a complete information, this would help us in my work pretty much. Thank you so much!!

Excellent quality video on a very misunderstood yet critical subject - Keep up the good work!

You guys always have fantastic tips for those starting in the industry! I'm recommending to the college that they include your tips in standard curriculum.

Excellent video about a topic many ignore.

It needs 2.09 gallons of coolant added and 8.91 gallons of water If it has 44 gallons at 4% then there are 1.76 gallons of coolant in the tank already. 55 gallons at 7% would be 3.85 gallons of coolant. Therefore 2.09 gallons of coolant are need to bring the quantity of coolant in the tank up to the correct amount. Next, by supplementing with 8.91 gallons of water, the top up solution will raise the quantity of fluid by 11 gallons and to a concentration of 7%.

I use to get electrolysis bronzing on my aluminum part. The problem is much deeper with the machine but i treated the problem by lowering the PH in my coolant that prevented the electrolysis effect with the coolant. Also it helps to use coolant made for non ferrous metals or ferrous metals depending on what youre machining.

Great video. My work is getting a VF4-SS real soon. Awesome info to learn beforehand

Great video! Just needs more Terryberry!

Great video, congrats !

Andrew, at 19:17...…..Always remember to lift with you legs and not your back.

Very informative indeed, but all I could think of was "Poor Andrew"

Very proper explanation, thanks a lot!

Thank you very much

Coolant the movie? can't wait for the sequel lol!

I saw ESSENTIAL on the screen while he was pouring oil. Damn essential oils.

If acidity is the only thing that needs to be corrected, oxygen bubbled into water will make it alkaline, would that be good to do/use?

Great video Guys! What would have been very helpful is suggestions on for example Venturi mixer, cleaning solution, coolant that you Guys are using and for what type of machining??

i dont know what the fuck im doing here but even tho im not a machinist i keep whathing these videos for hours ...

Excellent MOVIE, indeed.

Andrew, thank you Andrew.

Just add your 1.32g to the 44g, and subtract that from 55. You get 9.68g. now just mix up 9.68g of coolant mix. It's less steps and more accurate

Where did you get the 55 gallon white drum that has a spout on the side and an opening for the coolant to be poured in while it lays on it's side.

Thank you for the video. Lots of good info here. Any chance there is a plan on a coolant maintenance video for the ST10 with the integrated tank? We just got an ST10Y a short time ago. It seems that everything is hard to get to and not nearly as easy as it is here for the ST30. I may be missing something but would be great to have how Haas expects operators to maintain an integrated tank for the ST10 series. I've looked everywhere and there seems to be little to no info on this subject. Thanks for the great videos!

My mind is sorta blown that bacterial accumulation is a problem with machining. I just never thought that'd be a problem. Then again, they've developed bacteria that can eat plastic so...

Could you please suggest the Alkaline Cleaner which the manufacturer recommended for a thorough cleaning?

Great video series. I just got my first VMC and have a lot learn. Your videos are super helpful. What high alkaline cleaner do you recommend or use for cleaning the tank and coolant lines?

Where do you get the bacteria test kit?

Patrick Bateman is now doing commentary’s for hass yt videos

At 1:07 what are those fittings on the turret to the drill and where can I get them. I've never seen anything look that unjanky before.

Non-moving coolant/heat in summer can be problematic too, guys.

Hard job for Andrew!

great video on coolant basics and maintenance. The flow of info from Haas is not matched anywhere else in the industry. My only comment is that the video at 29:19 mentions a "chip strainer" that comes with your new Haas machine. We just took delivery of a new VF-2SS in January 2019 and it did not come with the chip strainer basket and filter cover as shown in the video. According to the HFO Tech that performed the installation, Haas machines are no longer shipping with the chip strainer and must be purchased separately. I did purchase it as the Tech highly recommended. It was only $75.00. I also added some 100 micron filter felt on top of the basket but under the Haas mesh filter (from McMaster.com part # 51625K37 ) that eliminates most of the fines from even getting into the tank.

Thanks

Andrew is a pretty smart guy :D .

Get your shit together Andrew, time is money.

Cool ant informative vijeo

Why not always use the chip strainer?

Follow this video and save andrew's hardwork

It's funny seeing them calculate the amounts to two decimal points, but then forget to deduct the amount of concentrate added to the existing coolant from the 11gallons, resulting in a mixture that is too rich. Close guys, but not quite :D

Abom size drill 20:38

Great vid. Where can we order a chip basket and strainer?

Can you talk coolant hoses? The difference between the old black hoses on a vf2 and the blue garden hoses on a 2018 vf2. Why the switch?

Most people will fail the math lesson.

I use an old Milltronics VM-20 and there is no filtration system whatsover. The coolant already looks nasty and i have no idea how concentrated it is. I dislike working in shops who won't buy necessary things for their CNC machine

My brand new VF2 did not come with a chip strainer shown in the video. Where can I get those? Andreas

@ 24:00 take that outside Andrew and pressure wash it & get a cordless drill. F all that hand cranking.

Goodmorning world. The earth says hello!

that's cool!

We test the coolant with refractometer using the running coolant not sitting coolant in the tank. I wonder. In terms of filling we usually just use whatever space is free since most machines we have won't overflow to the floor unless you wayyyyy overfill it. They have pre calculated measuring containers. The hard water is interesting though bc I'm pretty sure we use hard water. This makes me want to clean all of the coolant tanks real bad lmao fuck

My name is frank Woodall I am on the engineering team at zebra skimmers and we make the tube skimmer for haas machines. Coolant Mait. Is what we do! If we can help in any way please reach out haas!! Love the videos!!

Recap: 29:35

લપ વાળું કામ છે ભાઈ... ।!

What test strips do you use ?

Lo puedes poner en español por lo k se muy buen video

Would the same coolant rules apply to a machine like a surface grinder?

could you not just place some UV lamps inside or over the coolant tank to constantly kill bacteria? (at least most of them)

17:55 Coolant mixing ASMR.

🇧🇷Daniel Machado - Brazil🌎🇺🇸

Ha imperial unit calculation. Hahshahaha!

Why would Haas not put a simple coolant calculator in the software? Dah

Looks like Andrew’s been fucking off with coolant all day when it shouldn’t take but 5 minutes to top off the water directly into the tank at 53 gal and keep adding the solution until it reads a bit over 7%

Oh and getting coolant to drain in a mill. When you run an aluminum job

It's so complicated .....I just want to make chips

why on earth, a person with nothing to do with cnc machine like me, watch this whole video?

🥰😁🥰

Be like Andrew

You dont pick up chips with latex gloves. You’re better than that HAAS

ehhhh just dump a lil coolant in some water and call it good.

Poor audio quality! hard consonants are very prominent and distracting. get a pop filter for the mic. Volume swings considerably, even within the same sentence. Move the mic further away, and clean this up in post-processing using compression
