自制磨/钻床
这个帖子其实并不是自制磨床钻床,而是老外买的废旧的设备进行修复改装。这套报废的老外共花了75美元。我也觉得这么大的设备花75美元简直太便宜了。也许是其国家物价低吧。我国废铁也不一定能买到吧。不多说了,还是看看资料吧。

开始发原文了:
I was browsing the local ads and saw this ugly drill for sale for $100, the picture was bad and you could only see the outline of the machine. The location was near so I decided to go have a look. The Drill/Mill was in sad shape and homemade but had potential, this project was quite the achievement. I offered the guy $75 and he took it. I don’t know if it was a good deal but it certainly will keep me busy for a few weeks. I already started stripping it down to nuts and bolts and cleaning. It took me a while to figure out what the dangle ling gear box was for but the penny finally dropped, it was for a horizontal milling shaft. That part has to go. I will try to post more pictures as the project progresses.

Got the mill all stripped down today, cleaned the base and the knee support then checked it out for squareness, I got .010” per 4 “ … not so good. O mounted it on the 6X12 surface grinder and ground it square. I was looking for 1 to 2 thou per 4” but I lucked out and got .0004”. I turned off the lights, closed the door and had a beer.
Randyc…. The knee is home made. Everything is homemade except for the screws and maybe the lead screws, all of them parts are still dirty so I will report on them later. Horizontal mills I never liked, except for the Devleig, and even then, mounting heavy parts on an angle plate is no fun, you keep dropping everything.

Here is a few pictures of the table and the knee.. Today I reground the male dovetail on the knee support and the mating face on the knee, I now need to check for squareness.
Randyc and powderhorn01, thanks for the suggestions. I really like the H5700 holder but not sure if I can use it yet. The other option would be to modify the nose of the spindle to accept ER-25 Collets and retaining nut. Anyone know what size the collets and nut are.
Thanks..

Been busy for the last few days re-machining, modifying and trial assembling the mill/drill. I made a set of dials for one end of the table, not graduated yet... The misfortune here is that the lead screw is 6 TPI, that’s .166” per turn. Not drastic but will be a PITA. The Y axis is 8 TPI, much better.
Now I need to work on the knee elevating screw with the bevel gears.
After that, THE HEAD, I think my choice is made, I need to take a few more measurements and evaluate the possibilities before I commit.
