If I need to bore a hole larger than 1/2 inch, and the work piece will not mount in my lathe... I drill a 1/2 inch starter hole with the work piece mounted on...
I'm in the midst of a similar project - I've got to bore a 1 3/8" hole in a piece of 1/2" Aluminum. Question: If I start out with a 1/2" hole, how heavy a cut...
... I take about 0.025 or so at the max, with a slow feed, you do not need to use the microfeed, but you do need to develop a feel for it. This will work for...
Thanks Harvey! This is exactly what I was looking for, I'll let you know how I make out. I might cheat a little and start out with a hole saw to get me close...

I bought a speedway mill drill with the round column and had trouble keeping
it indexed in, plus every time you move the head. you have to set it up
again. I...
I use a end mill up to 1 1/2" then use a boring head. Grizzily has a end mill set with 3/4" shank in 3/4"to 1 1/2", feed them gentle and they work fine. i use...
You know, I ended up "drilling" last weekend with and end mill for small depths, and it actually seemed far easier on the mill than drilling. Now, the hole was...
... Yes, material buildup under the end mill. Look closely at the end of the mill. The cutting flutes do not go completely to the middle. (there are mills...
I want to clarify, I first drill a 1/2" hole then I use the end mills one step at a time, 3/4", 7/8", 1" etc untill I am near the finished size then I use a...
I recently purchased one of the fly cutter sets from Little Machine Shop (great place by the way). At any rate, I also had to purchase some tool bit blanks to...
Bob, I use a profile and angles just like a round-nose finishing lathe tool. It works fine. Regards, Ray L. ... Machine ... purchase ... Unfortunately, ... ...
I had the same experience with fly cutters. I think the usual shape is the "AL" style lathe bits. If you go to McMaster Carr's web page you can see one on...
Fly cutting is the same as a facing cut toward the headstock on a lathe. (the difference is the workpiece is stationary and the toolbit is revolving) I use a...

Hmmmm.... It has servo motors and ballscrews, yet he says it's only good for +/-0.002". It should do better than that. I think at $1000 it's probably an OK...

Hello all, It seems that the G1007 was a bad idea. How about the Griz G0519? I am working with small to medium parts. How precision is this machine? .002. Is...
i just purchased a 12" scale with the digital read out and i was wondering where most people mount it. i usually see on the left hand side of the mini mill (by...
... If you mount it on the left side, most people replace the arm by a gas constant pressure spring. That allows you to put the scale on the left side. I left...
Ok...down to the 1st of 2 holes to be tapped w/ a 2-56 tap. This is in Brass. 3 pratice holes came out perfect, but when it came down to it on the final work...
I studied the problem of mounting a digital readout on the Z axis of my mini-mill. Didn't see an easy way. But, on thinking over the problem, I realized that...

Try a centercut carbide endmill. Clamp your part on the mill and start slow proceed with lots of vacumm to remove swarf. It will even work on hss taps. John...

I've been following the group for a while and hopefully an expert out there can help me get my mini mill back working again. During my recent move the control...
Yes. Don't take such aggressive cuts. That's the machine's way of telling you you're pushing it too hard, and will lead to broken gears. If you want to cut...
