Hello everyone,

I was just offered dibs on a 1985 Mitsubishi DCW 110 for $2000. I want to build a 5 to 6 foot long x-axis with an a-axis for drilling .03" radial holes down 2 to 3 inches into...

It can be done with a 2D sketch.

Sorry, it was getting late last night when I wrote the 6 steps down. Here is a easier way to show you: ‪BRIDGEPORT MILL indicating the vise‬‏ - YouTube

For later reference...

Step 1.
Place one corner of the HDPE in the location that you want it.
Step 2.
Install a test indicator or similar measurement devise in the spindle.
Step 3.
Locate the indicator on the first...

Not much of progress, in the long run. but I have changed the design at least 8 times making improvements. I hope.

After carefully thinking about what people would really want and or need, I decided I would design the 1.5 nominal hp will be capable of 3.25 max. hp.

Does any one have a speed range that they...

This is definatly a challenging project for me to work on. I am used to designing horizontal motors, vertical motors are a whole differnt scenario.

As for ATC capability, I thought (4 months ago)...

It looks like I will be using 307 15 degree ABEC 7 angular contact, on the cutter end. ABEC 9's will be available upon special request.

I will likely be using smaller on the encoder end. Yes I...

Cost: At this time I am not sure. I am still in the "rough design" stage.
Weight: at this time the 10HP is going to be over 30 lbs.
Size: in the rough design stage I can not...

Dick:
our large motors have runout of .002 inches. I would personally like to guarantee a runout of .0001 or less. But of course the majority of the runout will come from the bearings. I hear many...

Osphoto,

As for the spindle holder, I am trying to design it with mounting features attached to the motors. Sorry I can't attach a picture, I tried twice. :confused:

As for the runout we try to...

carlcnc,
yeah, it is hard to compete with the Chinese, but looking at the 10K spindle motor sold by Keling CNC, and the very terrible reviews that I have heard makes me want to stay away from them....

osphoto,
I am currently only in the mechanical design stage. I am using the longest stack I can get for the diameter that I am using. For those who don't know the what a stack is, it the part of the...

Hi everyone,

A little about my idea :idea::
I work for a company who does design work for Reuland Electric. My company also designs our own high speed, high HP motors. The previous one we...

I hope it is more probationary, other beginning machinists in this area, that I know are making $15+.

Oh yes, I also have one, 28th edition.

Hi all,
First of all it has been over 3 years since I have even stepped foot in a machine shop. I worked in one back in high school, but it was very limited on what I could do. But the things I do...

I would go with the optical limit switches. I hear that the mechanical switches fail faster than the optical. But I have never built a machine yet, I have been drawing a small industrial quality...

Depends, last year I got a great bonus. Management closed the other fabrication shop and not the one I work at, so I find it a bonus to be employed. As far as a $$$ bonus, no.
Last year the ones of...

This guy might have some information.

Do you have a Machinery's Handbook? They have about 300 pages with these formulas and properites of materials they even give sample problems explaining how to use the formulas. If not you can try...

uhh ohhh, I calculate the max stress as 56515.444, (500 x 2.342) / (4 x .00518)
Is there a professional engineer who can give us an answer?

From what I understand is that once it passes the yield point it will not return to shape. The yield point for SS316 is 35,000psi and SS316L is 30,000psi. I am thinking its a go. But I could do the...

every thing bends under a load, how much deflection will you tolerate? I am not an engineer, just read the books for fun (yes I am very strange), I just looked it up and did the math and I calculate...

I Tried taking a Picture and never got a readable picture so see attached.

Do you have the belt? If so there are some measurements I can give you to determine the size.
the (thickness/distance between ribs) of H=(.12/.063) J=(.16/.092) K=(.24/.140) L=(.38/.185) M=(.66/.370)

Machinery Handbook 28th Edition, page 2427 to 2429. I think it is a V- Ribbed belt is'nt it?

Is this it?

The web thickness could vary as much as a 1/16". I think I would suggest buying cold rolled angle, cold rolled does not have to cool down after it is shaped while with hot rolled one side can...

A little about myself: I have been working as a structural steel detailer, the guy who takes engineers drawings and makes new drawings so the people in our fab shop can make it, so I have to come up...
