Milling Machine Upgrades - Hammer/Wrench Tool + Spindle Lock
Вставка
- Опубліковано 9 січ 2020
- On most manual milling machines you need at least two tools to change the tooling in the spindle, often three like in this case. Most (cheaper) machines don't have a spindle lock built in, so you usually have use one tool to block the spindle from rotating, one tool to loosen the drawbar, and usually a small hammer to knock the tool out of the tapered spindle.
This process gets pretty annoying and costs some time if you have to change tooling a lot, so I came up with a solution to make it much more convenient and faster.
First I made a combination tool that contains a nicer, adjustable drawbar wrench as well as a spring loaded hammer in one tool, so you can loosen the drawbar and knock out the tool in the same process. In addition, two locking rings on the rigid and rotating part of the spindle provide a quick way to lock the rotation without using any tools. And as an additional feature, screwing the rings together allows to lock the spindle completely solid, which makes it possible to use the quill to cut keyways and similar features into parts features that you would normally need a shaper for.
The idea for the drawbar tool comes from Frank Hoose who's got the same Mill and a great UA-cam Channel with tons of cool ideas like this, check him out: / @frankhoose
If you're wondering, this mill is a Sieg SX4. The same machine is sold in the US by Grizzly as the Grizzly G0720R

Brilliant! The only problem with your videos is that there aren’t enough of them! Great work!
I agree :/
Even though I don’t have (never will have) a milling machine, I liked that a lot. Your thinking and designing skills are very instructive. Thanks! Les
As Stefan would say. Making tools to use tools to buy more tools so you can start all over again and make some more tools. Great videos, I love them.
Great work, Phil, your videos inspire me a lot! Got to know your channel with the catamaran series, and have been enjoying all of them ever since. Thanks!
👍 Danke für's Hochladen und teilen! Echte deutsche Ingenieurswertarbeit mit Präzision und viel Hirnschmalz! Deine Einfälle sind phänomenal - ich gratuliere dir dazu! 👍
The first tool was wonderful. Simple and so useful. Anyone with a mill should make one.
The second part is lovely. But it's a bit beyond me right now. Beautiful work.
Such a cool video of the process, the process is everything! I hope to be as methodical and precise!
Awesome work 🔥
How does this only have 11k views? Great video and awesome engineering!
Very elegant solution.
I can appreciate someone that makes due
with what he has because that’s what I do.
You probably could have made a Power
Draw Bar in about as much time.
Nice work but I’d lose the gloves.
Wow dude! Really nice job!
Quality build, nice job!
Great stuff. Keep up the excellent work
'Wrammer' :D Brilliant video!
Excellent job
congratulations friend, great job and very functional
This is cool idea! Bravo
fabuloso ,good video and great work , making tools for your machine is good because you go forward in your work and in your mind
Awesome!!!
Found you via a comment you posted on a ToT vid. Hit the sub button, looking forward to checking out your older uploads
Great idea!
Beautiful
Super smart
Ahhh i love a good solution!
Outstanding improvement! What a great video to watch! One thought if I may: It'd be nice to have an interlock that disables power to the motor when the locking pin is engaged. I can see the off chance situation where 1) the pin sticks and 2) for some odd reason you forget to check it before you power up.
That's actually happened already so not a bad suggestion 😅 However, I was lucky because the built-in VFD in this machine has overload protection. So the motor was disabled automatically and it just displayed an error message - didn't even know they could do that. It worked fine after resetting the machine. I'm not sure what would have happened on a geared machine without a brain box, but I imagine it would have sounded crunchy and cost a lot of money... or maybe the clamping ring would have just slipped. Either way, good idea, and wouldn't be too hard to do, but I fear it's one of those things that'll stay on my "maybe someday" list for a while.
Hi Phil,
I made the hammer wrench tool for my SX4 awhile ago after seeing Frank Hoose on mini lathes, his version has a ball on each end of the handle which gives you a gyroscope effect, one flick of the tool & it almost undoes in one go. I use a C spanner to hold the spindle
as on the SX4 the hole for the pin is on the bottom of the quill. Might have to look at the spindle lock as yet another project!
Yeah I saw that on some SX4 machines there's a hole for the locking pin at the quill, but I think it depends on which spindle version you have. This is SK-30 (or ISO-30) and it seems like only the R8 taper machines have that hole. And you're right, Frank Hooses tool is much nicer, but I decided to go without the balls, the spinning thing still works somewhat even like this
Another winner. New sub here.
Very innovative Phil, I need to try this on my Bridgeport milling machine, could you share some drawings of the tools that you've manufactured so that it would be helpful,
Cheers and love from India
Awesome vids, love your dry jokes
Wie immer Top 1A 👍
Innovative big time ,, I use a cordless impact gun to tap and turn the draw bar .
Very nice
Fantastic
Grizzly G0720R, thanks for letting us know.
Respect ! No other words needed - you are the master dude ! :)
Such a great video, My SIEG SX3L Is arrived from Paulimot last week, i Will start to make your idea this week end, because It Is very useful and nice! I want to try to use alluminum instead of steel, to make the big rings: i have in My workshop ( 110 mm external diameter) so i will try to see if i can make enough friction on the spindle!
Spettacolo !!!
Handy!
Awesome. Did you ever consider a cam lock between the two rings?
Very nice tool holder, what kind is it?
Nicely machined. However, I think I'd have gone for a spring-loaded pin on top of the mill to keep the lower part of the spindle clearer plus, it could be bolt action. Also, I wonder how the balance of the spindle will now be especially at high speed?
Yeah I had that thought too, would have been a lot easier to make but I didn't like the concept of blocking the spindle splines with a pin (like the manufacturer intended) because there's not a lot of contact area and the splines were already starting to wear out from it. I've seen a solution on some other channel though where somebody built a sort of socket that matches the spline profile and locks from above, that was pretty smart but I can't find that video anymore.. Anyhow, I also wanted to be able to lock the spindle solid for slotting cuts where there can't be any movement and the rings seemed to be a good solution. The rings are pretty balanced so I haven't had any problems with that at high RPMs, runs just like before
@@PhilVandelay Thanks for the reply. My main concern was with the spindle balance but if you've seen no change then it clearly isn't an issue. I also take your point about slotting. If you ever come across the other video please send a link as I'd like to see it.
you came up with the design of the spindle lock, but at the same time made an impact wrench ... why didn't you make the nut removal? nut puller, pressing the tool, which works on the principle of pressing
👍👍👍👍
Brilliant solution, did you do prototypes? Or was this your first attempt?
Nope, it's pretty simple really and I had seen similar tools before. Just takes some time and patience to make it
12:28 - maybe.
👍😊👍
Love the spindle lock. What make and model mill do you have? I have a RF-45 and it looks similar to yours.
It's a Sieg SX-4, yeah it's quite similar to the RF-45, same form factor
@@PhilVandelay that’s cool. I wasn’t aware they made it with that collet system. I bet that helps a bunch. Mine uses an R8 collet and the spindle bore is pretty loose unlike which is typical of the chinese imports except for the Sieg machines.
The Allen is no longer hardened and will eventually twist and break. Speaking from experience.
Have you seen how Adam savages mill does this. Im pretty sure it's like a rattle gun
Yeah it's pretty much a pneumatic impact driver on top of the mill. Pretty common for larger mills, but kind of a luxury feature for me. This solution is a good compromise I think, it's relatively quick and easier/cheaper to implement
Just curious. Did that add any vibration to the machine? If so how bad, especially at high rpms. It is a good idea, i would just be afraid of adding vibration to the spindle if it isnt balanced.
Not that I can tell. The rings are pretty balanced, the only slight imbalance is where the clamping screw goes but I think it's so little that it's negligible. Haven't had a single problem with this setup yet, but it has been extremely helpful and time saving
What quick change tool post are you using plz
Multifix A
What kind of milling machine is it.
🤨👍🏻
I’m looking to get a SX4 in the next month or 2, how does it perform with steel?
There's plenty of examples on my channel
@@PhilVandelay well that’s me subscribed, thanks!
Ich hätte zum lösen und festziehen einen Druckluftschrauber mit einstellbarem Drehmoment benutzt. Dazu dann noch deinen "Klopfring" dazwischen. Dann müsstest du auch nicht selbst schrauben. So wie hier: ua-cam.com/video/lTUmjiJELko/v-deo.html
how much are your tools and machines worth? :)
Less than most people assume. Most of them are cheap chinese machines (well, cheap in comparison)
@@PhilVandelay any chance for a workshop tour? :)
@@betims Yes I just moved into a new shop and I'm definitely planning on doing an in-depth tour once everything is finally settled there
@@PhilVandelay can't wait for the tour :) - your videos, especially the cargo bike have really inspired me. i live in a shitplace where is very hard to find decent tools and am thinking to learn some welding and start making electric butique bicycles. That's why i was asking about the tools and machines...
02:21 plzzzz dont you ever wear gloves when using a lathe !!!!!!!!!!!!!!!!!!!
You can use gloves, also on mills and drills. But only ligth duty ones, which breaks easier than your hand. We usually use nitrile gloves for the drill
Both of you are correct if you were to use cloth base glove it could pull more easily then your skin BUT theres certain gloves that can be used and were intended for machining work.
Wrench + hammer 😂😂😂😂, if it wud be that easy no one wud have used a hammer, look good on utube not in practical
quatsch- blödsinn.
Wow Danke für den super konstruktiven Kommentar!
