CNC Router Build For A Friend

[mactec54]

Here is the start of a build for a friend

This machine will be able to cut around a piece of material 12x18 with up to a
1.00 dia cutter

It will have Hiwin linear rails & ballscrews

Motors & drives to be decided on, but most likely will be a servo system

We will try to do as much as possible, Using manual machines,(Time Permitting) to show the different setups, to make the parts needed to build this machine

Some of the material's needed in this photo

Mactec,

Looking good! You know, you could save yourself some machining time by just using double-stick tape to hold the rails on, and pistol drilling the holes for the ball screw end mount bearings.

How big that rails?

If you look really close at the linear rails, that are in the photo they have no holes for mounting, so the the double sided tape, Is a great idea, & should hold them really well, As for a pistol drill, I'm sure it will get used

The Hiwin rails in the photo are 20mm & will be for the X axes the Y & Z axes will have 16mm rails

Today we will set up the manual mill to start machining the base frame

This is a small Jet knee mill & was one of the first one's they sold, it has been a great little mill

First we will Tram the spindle, to get it true to the table, & then we can start to machine the parts for the base

The base frame is the most important part to get right, if this is not made well
it will affect a whole machine

Tape? that sounds interesting, can you provide more details of what type of tape etc?

[mactec54]

The machining of the base frame, the aluminum pieces,were first deburred & then mounted on the mill & machined parallel

The 2 outside frame pieces, were milled for the linear rail mounting at the same time, The outside pieces are made from .750 Mic6 tooling plate

spoiledbrat & myself have a Joke about the double-sided tape & the pistol drill, as we were advised by a manufacture, To use this to fix his machine they had messed up on

It would be nice if there was a magical tape like this

[spoiledbrat]

Look at that immaculate workshop...

Have you ever done any work in there?

ok drilling and tapping it is then

Wow you're not kidding!

I thought all those photos were 3D renderings until I zoomed in!

Impressive.

How on earth do you get your machine that funny silver colour instead the normal colour, you know...

Brown.

That's how all my machines look,The work tables of a machine is very important to keep them in great condition, If you want to hold tight tolerances on the parts you make

That machine is more than 10 years old, It is just a Standard Manual Jet knee Mill, no read-out, no power feed, (Just handles to crank) But I did fit a VFD, I have had servo motors on the X axes, but only for testing different motors

I usually just clean up the area of,(chips swarf oil Etc)before I take the photos, to make them look better

It's called a shop-vac it takes over!! I could lend it to you,It know's what to do, & does not need any training

"It's called a shop-vac it takes over!! I could lend it to you,It know's what to do, & does not need any training "

Probably has too many buttons to safely employ in this shop...

If my mills were that clean they would feel absolutely NAKED. They actually like having swarf and oil all over them.

For drilling, tapping, & reaming dowel holes in the ends of the frame rails, a fixture was made to mount on the side of the Mill table

The fixture was milled on the edges & then set up on the Mill table, the Key slot was cut
90deg to the edges of the aluminum plate, the holes were then drill, reamed for dowels & some of the holes were tapped

2 steel Keys were made for the mounting

With the fixture mounted on the Mill, the dowels were fitted down one edge & a stop at the bottom, it then has
2 Mitee-Bite clamps on the other side, to push & hold the parts up against the dowels, The ends were ready to get there holes done

There are 2 reamed holes & 2 tapped holes in each end

My machines would never feel naked, they are always making something,material being cut on them as well as losts of cutting oils Etc, The shop-vac sucks everything up for the photo shoots

We're just teasing. It's a lot of work keeping one that clean. Mine get cleaned also, but fighting rust due to the local humidity is tough.

If you need a lub,anti rust, try this on your machines or anything you want to use it on,Even for cutting/tapping it works quite well, This will solve your humidity problems on your machines, The humidity is not to bad here in TN
