G0704 - Spindle Lock

[@bobuk5722]

Hi folks, Spring loaded lock is a very good idea but could require three hands, the alternative is an electrical interlock that disables the motor when the lock is engaged. It could be wired in series with the spindle chuck guard, or there may be a free connector in the control box. BobUK.

Just curious.... I have been using my air impact wrench. Holding it and then hitting it with 90 psi. Never had any problems. Tightens it just fine and loosens easier. No galling on the tightening rod either. I use a 9mm 12 point socket.

ProtoSimTech Would you mind making a quick drawing of the part? I'm planning on tackling this for my first project when my G0704 arrives. (Just no machine to get dimensions off of.) Biggest three dimensions I am worried about is ID of bore, depth of bore, and overall height.

[@toddgriffith5234]

Just a suggestion but a spring loaded pin would be much quicker to engage than a bolt for locking the spindle. I built one for my x2 mini mill and will be making one for my G0704 in the near future. Got a few irons that need to come out of the fire first.

Good job well done even if you did" mill it the wrong way!." I mill the wrong way too becauseI I'm not a smart arse like some people who make stupid comments. Thanks for sharing ,excellent camera work as well.

[@bobuk5722]

Ok, lack of tools. It's a problem. A rough guide is that the necessary tooling will approach the cost of a hobby style milling machine. I suggest buying as needed - need to plan ahead a bit so the tool is available when needed. BobUK,

Swapmeets...I find alot of tool holders at them most at motorcycle Swapmeets... the automotive ones can at random find machinery

You could also hold it by the ID and turn and face it on the lathe? You can mill in either direction. Dont sweat it.

Great video! Do u sell these? I'm looking to get one for my G0704 I just purchased

[@ProtoSimTechnologies]

mikeyeyes7 Actually, no. We don't sell or make these. This is one of those products that not a lot of people would need or want. I doubt we'd sell very many of them. Good luck with your new G0704! You'll definitely enjoy using it. It has it's drawbacks, but it's a very capable machine. It has served me well over the past year and a half.

06:55 it is better to have a slightly dull HSS insert for getting mirror finish on aluminium. Thanks for the video

[@RoboCNCnl]

Nice one...

[@basemkhoja4498]

Vari nice

[@myworkshop2]

I'd love to be there when you forget the lock and turn the machine on ...... spring loaded stop would have been a better idea.

[@mikstratok]

you didn't need a 90 deg face mill, just needed to get creative with the band saw

[@ProtoSimTechnologies]

This video is 4 years old. I've since learned a heck of a lot more about milling, and machining in general ;-)

[@dodienko]

Now what will happen if you forget the spindle in lock position and turn the machine on? There is a reason why the milling machines not coming with spindle locks. I bet someone already done it.

[@scotty362100]

That is why everything you buy today comes with warning labels all over it, and there are so many government regulations......IDIOTS!

[@Rasmus661]

Why are you milling the wrong way? You only have to mill counter clockwise on a very old mill with lots of play. If you are milling outside the part then it's clockwise and it's counter clockwise if you are milling a pocket. You will get better tool life, surface finish and less chatter.

[@ProtoSimTechnologies]

Hey Rasmus, I don't know if there really is a "wrong" way to mill. Yes, there are advantages and disadvantages to each type of milling, but I don't know if it's the right thing to do to label either way "wrong". I don't want to get into a pissing contest here, but I'll try to explain this the best I can. In the video, I'm milling the part using "conventional" milling. This is where you get the best finish (at least in my little experience). I'm milling "against" the part. The best way to explain this is to think about a car moving forward but the tires are going in reverse (the tires being the end mill). Here is an image to explain what I mean. The image on the right is how I am doing it in this video: tinyurl.com/nargbf6 I'm definitely new to all of this and I'm getting the hang of it, but let's try to refrain from labeling either way "wrong". Every machinist has their way of doing things, or a way they've been taught to do things. There may be some cases (as you've suggested) that call for one type of milling over the other depending on different variables or customer requirements, but this is how I chose to do it with this particular work piece. Thanks for the comment!

+ProtoSimTech Pretty sure you guys are just talking about "Conventional Milling" vs "Climb Milling" both are valid techniques if you know what you're doing and have the appropriate machine for it.
