Yes I do, I use it to sync screw compensation. Home switches on both axis.

I have been running my converted lathe for a while now. but a problem keeps bugging me, I have a workaround but I would like to solve the problem the correct way.

here is a video of the cut

I am turning Drill steel used in oil drilling operations. to the best of my knowledge it is 4140 at about 40HRC, it turns pretty closely to 4140 QT. I want to improve my cycle times and have been...
peter, so obvious of a solution, and simple with a lot of advantages. I am a little mift that I didn't think of that.
elfrench, I will most probably not be gluing the cars to the X carriage....
[QUOTE=peteeng;2446054]Hi Ray - Nature would never build something with absolute regular spacing. If you make one of those thin plates by accident the correct size that vibrates you will have a huge...
This is what I am getting ready to run FEA on. I am still working on it but I decided to make life hard and weld up a frame out of 16gauge sheet steel. The machine stiffness should be way higher then...
those physical tests are what I would expect to see, I must have interpreted your FEA wrong. the 100N thing is a normalized test. if I were to apply it to your tests it would be something like:

I converted a colchester clausing mastiff, I had to slow it down, 600 ipm rapids on the x axis is too fast. I limit it to 100 ipm usually to give me half a chance to hit the estop. most of the time...
yeah 68 for 6061 and 71 for 7071 (according to google), not much of a difference.
you could try an air spring. https://www.mcmaster.com/9539K48 this will actuate 3991kgf at 100PSI air pressure and is only 2.6 (6.6cm) inches when not actuated.
sounds good to me. for my current project I have crap lying around that I am going to play with. I have over looked them many times in favor of other better rails. I think I originally got these for...
looks pretty nice. are you expecting 1000lbs of torque on the column? I am just wondering what type of machine you are going for. high HP low torque or High torque low HP. looking at the ratios of...
Anyone know the approximate stiffness values for mgn12 block and rail or similar? I am going to do some fea simulations but I would appreciate corroboration if anyone has any.
thanks,
I would start by finding the torque that your spindle will produce. This will be the maximum cutting force that your machine will see. If you are running 12mm with a 5.6KW spindle @ 24000 RPM the...
looks great! I am interested in how it performs. I think there are a lot of methods available to damp the structure. and it looks like it will have good stiffness for accuracy in cut as well as...
the heating elements are Kanthel 110V 1600W each, the furnace is fairly well insulated with light firebrick, I am using a heavy duity exposed K type Thermocouple, the elements are controlled with a...
there are two elements, totalling 2600W I have a furnace controller on it too in order to control the maximum furnace temp. I am not usually in a hurry, but I think it takes about two hours to melt...
thanks,
I used petrobond, with an electric furnace. this picture is from the melt on this project. I have since fixed the element that fell from its groove.
The design starts with the spindle casting, I modeled it with fusion360, then 3d printed it, I used the 3d printed part as a pattern to sand cast it. it was the first time I used a 3d printed part as...
it has been a while since I have posted. so I figured that its about time I be a bit more active.
I decided I needed a live tooling spindle on my lathe, my concept is that it will be mounted on a...
I am threading an 8-acme inside thread, I set the Q to 14, however the cut angle is much greater than that. probably closer to 20 or even as much as 25 degrees. when I cut a 60 degree thread and set...
have you estimated the stage compression ratio? At such a small scale the blade airfoil matters less due to the Reynolds number. what is the compression ratio that you are shooting for when you have...
Well it looks like this is the forum to post builds. So here is mine.... A long time coming. I have made lathes before but this is my most ambitious project yet. I have had this plan for years but...
Well I decided to do it 30mm x 10mm lead, here are some pics. I constructed a steady rest for the project and made a form tool. There is a small amount of chatter. I am looking forward to test its...
ger21, thanks for the force estimate. I was originally thinking about a gantry router with about 2 hp spindle. I might try it on a metalworking lathe project I am working on. I have an old textbook...
I am wondering if anyone here has attempted to make a ballscrew? Also I am used to working with hardened ballscrews, but I know that some ballscrews are made from relatively soft material, and...
I have my machine hooked up to a DNC program on a computer. it transmits the data reliably only part of the time. I can correct this by removeing all of the end of block characters that do not...
I have an old Matsuura, it is a 760V circa 1983. I plan on running some aluminum parts on it. the spindle speed maximum on this machine is 6000RPM, my question is by experiance, how reliable is the...
my sand isn’t right. it wont release. also I don’t have enough sand. this puts a damper on things. unfortunately the lack of sand makes the coup and drag design more difficult. I have been having...
