We Have Milling Chucks on HaasTooling.com - Haas Automation, Inc.

[@raystanczak4277]

I appreciate all the teaching you do at Haas. yesterday I caught the vid on taps-all kinds of details that really matter, but which many of us don’t know. I pass this knowledge along.

[@j.r.3215]

Glad to see video in 4K, easier to see details...thanks.

You should never use a pushing motion to break something loose, that's how you slip and smack your fingies, a controlled pull is better. Safety first.

Where did you get the tool holder tightening fixture?

[@ffagilar2245]

Those things are massive.

[@BaldurNorddahl]

What is the advantages of a milling chuck over a hydraulic chuck? It is much the same, using sleeves to reduce size etc.

[@danm726]

There is no advantage to this system, this is a gimmick marketed towards people with little knowledge of tooling and a blind devotion to haas...

[@sibixis]

Its cheaper

[@BaldurNorddahl]

@@sibixis the list price of a Schunk tendo e hydraulic tool holder is almost exactly the same as the price listed for this milling chuck on the haas website.

[@steelfalcon2755]

@@BaldurNorddahl yeah... Schunk also produces hydro holders where the hydro portion is inside the actual tool taper, so gauge lenght is incredibly small...

[@sibixis]

@@BaldurNorddahl ahhh i didn't look at haas price i was just talking generally. Purchased 3 milling chucks for 590eur total and 2 hydro for 670eur. So milling one is under 200 and hydro a bit over 300.

[@TheDayzman]

Why are they designed to have a long Gage length?

[@Iceberg86300]

They aren't "designed to have a long gauge length," they "have a long gauge length, _by_ design." I.e., the underlying principals of their operation dictate a long gauge length. Think of them as ultra heavy duty mechanical shrink fit holders b/c, essentially, that's what they are.

What's the runout?

[@toolingwoman53]

Very helpful, thank you!

[@Владимир_Сабиров]

Ok, fine. But can you also release a metric system version, for people who don't like fractions and bunch of numbers after decimal point?

[@Verifraudreports]

Made in USA ...NO..it will happen when sandvik starts making imperial tools. ... dealwith it and use maths

[@IanMcDoe]

@@Verifraudreports Doesnt work tho. If you need to use a 10mm endmill you need a 10mm endmill. There is no getting around that. Would be nice if they offered the sleeves in metric increments the same way you can get er collets in inch sizes despite beeing a metric system.

[@jonassvensson9574]

@@Verifraudreports Sandvik has imperial tools

[@Foomanlol]

@@IanMcDoe They will probably offer metric sleeves. Haas is sold all around the world and can be run in metric mode afterall. They are focusing on US market first.

[@dsfs17987]

this isn't a haas tool system, I have these same holders made by BIG, metric collets (or sleeves) and everything, good holders, they are on the large side though... and long gauge length

[@தமிழ்பிரியர்கள்-ச4ன]

I want to join Haas... Is this possible?

[@danm726]

I dont get it, whats the advantage of these over er16, er32 etc, collet type holders? Seems those are more common and probably easier to find.

[@ydna]

the milling chucks have drastically higher holding force compared to collet holders. They're good for roughing since you can put a LOT of cutting force on a beefy endmill and yank it right out from the collet.

[@danm726]

@@ydna they have hydraulic holders for that purpose, or heat shrink (both have minimal runout) if you really want to spend money. This really looks to be another haas gimmick, sorry if that sounds harsh. Not to mention most haas machines arent rigid enough for most folks idea of "heavy roughing". Also, "profit milling" toolpaths are all the rage these days (longer tool length engagement, lighter stepover, faster cuts). I'm sure some people might find these useful but i dont think these are going to catch on with many folks.

[@ydna]

@@danm726 Haas didn't invent these. Here's a list of average available holding force for each one: (data from Sandvik) ER32: 20 kg*m 3/4" dia hydraulic: 25 kg*m 3/4" dia heatshrink: 48 kg*m 3/4" dia milling chuck: 75 kg*m 1.25" dia hydraulic: 43 kg*m 1.25" dia heatshrink: 78 kg*m 1.25" dia milling chuck: 175 kg*m For holding force alone, the choice is pretty obvious. The problem with hydraulics is they can fail pretty easily, and they're also VERY expensive per holder compared to everything else. Heatshrinks are good for long extensions but terrible for heavy roughing, and require a large investment in the induction unit. Everything has its place, but if you haven't pulled a tool from one of those then you're not cutting hard enough.

[@danm726]

@@ydna yea i know they didnt invent them but theyre somewhat obselete already when you look at all the different availabile insert tooling you can use and the different types of toolpaths that are becoming more popular that dont use as much heavy roughing.

[@ydna]

@@danm726 I'd say it depends on what your goal is for the cutting. If you're not concerned with cycle time and instead want to limit the engagement, HSM toolpaths are cute but that's nowhere near the capability of a production CNC. Like you said Haas aren't the most rigid but they can handle it easily so long as you don't go above a certain tool size. Now if somebody has a Minimill or TM where the spindle power isn't available, or a 30 taper with less rigidity, a milling chuck would be a bad idea. But if you want to get that material out of there without limiting things, and the machine is capable of doing it, well there's simply no replacement for displacement :)
