First mill chips

[DavidR8]

Nothing of any consequence, just wanted to see how it felt.
Was all shaky till I remembered to tighten down the column bolts. Doh!
3/4” 4-flute end mill, mild steel, 5 thou DoC, 50% step over, unknown feed rate.

Learned:
Need to tram!
Need sharp end mills
Cranking will get old...

Alright, now we're talking! Just what I have been waiting to see! And the plus is before 11:30pm this time! You getting better already!

Good job! Yes, sharp end mills make things much easier and better looking.

I can see a power feed in my future.

Get the DRO first, it makes life so much simpler and costs half of what a power feed does. I have been playing with the idea of a home brew power feed made from bits and pieces. With a little planning I think I can make it work.

I’m interested in how you rig up your feed.
DRO is on its way
I bought the unit in this thread. I exchanged pm’s with gravydog and decided it was what I was looking for.

Mounting 3-axis DRO to my RF-30 clone

After getting my mill set up, the first thing I wanted to do was install a DRO so I wouldn't have to deal with the runout on the X and Y axes and the inaccuracy of the dial on the Z axis (dial marked in thousandths but a full turn is actually only 0.084" instead of 0.100"). Also, they are just...

seriously, you are off to a great start!

learn the difference between climb milling and conventional milling as in regards to your spindle rotation


remember this if nothing else-
climb milling is for only the lightest of finishing cuts
conventional milling hoggs of the material

Thanks @Ulma Doctor!

Definitely. I was hyper-aware of the rotation and feed direction so as to avoid a climb milling situation the first time out.

I recall the first time I ever climb milled with my router table. 10,000+ rpm in maple. That got real fast even though I thought I was completely prepared for it.

How was tramming in the vise?
