The Sajo mill is here
Trion:
Thanks for the kind words and gratulations :nrocks:
Special thanks to Bernd and Darren for again sharing good advice :thumbup:
I found a small vise from a drill-press in the workshop today, will be using that one for starters. Might give me an indication if I should get one with swivel or not, when I buy a proper one..
I have quite a few different sized milling cutters, so I think I'm going for a metric ER 40 collet set. I can allways buy individual endmill holders for the cutters I use the most, afterwards. Or even try making some on the lathe, like Darren :dremel:
Today I continoued cleaning the mill, and have taken quite a few photos. But I have to leave for a party, which I'm already late for, so the pictures will have to wait until tomorrow :poke:
Trion:
Here are the pictures of the progress over the weekend :)
I still haven't got the proper electrical contact to be able to run the machine, so I'm using the time when everything is new and exciting to clean the machine properly, as it wouldn't have been done otherwise..
I continued cleaning the machine, and came to the electric cabinet. Here the oil had dried, so I had to use ethanol to clean it of. You can se before and after, as I have not cleaned the fuse door yet.
When the cabinet was looking so nice and clean, I found the switches to be looking quite bad, so I disassembled them and gave them a cleaning
Here they are all assembled again :dremel:
Cleaned electric cabinet
Afterwards I began to clean and inspect the table. I had noticed a strange looking M8 screw with two washers sticking out of the rubber way-cover of the Y axis, so I removed the cover to see what it was..
It seems to be the adjusting screw for the slack in the ways, which has had a shim mounted behind it. Not really shocking on a near 40 year old machine..
I also removed the dust cover behind the table, lubed everything good and moved the table back and forth wiping of all the particles that came out in the oil, until there were nearly no more to be found.
Then the way covers were cleaned and put back on again
Next was to clean the X-axis ways, so I cranked the table all the way to the left. Now I know what to do, next time I'm in the workshop and I'm feeling a bit cold... ::)
I noticed something looking like major swarf marks, but i soon discovered that these were part of the oil distribution system from the central lubrication. When I cranked the oil pump, I could actually see the oil bubbling out of these grooves. + points to the Sajo engineers for that one! :clap:
I then cleaned the ways for old swarf, before I cranked the table to the utmost right position, while turning the oilpump aswell.. I think I have now learned what is necessary, to truly appreciate rapid axis feed :lol:
Then I cleaned some various bits on the table, before I cranked the Z axis up. Not very hard work, but when the table moves about 5mm per revolution and you have the number 465mm in the back of you'r head, it requires some motivation :whip:
After having cleaned the Z-axis ways and given them a good lube, I had very good access to clean the stand.
But I soon figured I had to do something with the nasty looking coolant holes first.. I put my hand in one of the holes, only to discover it beeing almost top filled with swarf and some other gunk.. Brings back memories from the times I used to work on a farm :poke:
Luckily I discovered that what I had been digging in, was a filter. After I pulled that out, I could feel that there was only about a 1cm (0,4") thick layer of gunk on the bottom. The rest was actually coolant or oil! :thumbup:
But how was I going to get it out of there, when I wasn't able to run the pump? Yup, dont mind that big plate that's screwed onto the coolant reservoir, find a small cup (a spray can lid) and get it all ut by hand from one of those small round holes...
I got the 25 liter can almost half full, before a friend of mine came by. By then I had a mixture of coolant, oil and that thick gunk all the way to my shoulders, when he so kinly noticed "That plate in front of the coolant reservoir, It's just for cosmetics, right?" :bang:
Then I did it the easy way, found a big plastic bag, removed the cover, and out came the coolant..
I flushed with some 50 liter icewater from the stream running nerby the workshop, cleaned it a bit, and woila :beer:
How it stands now :)
That's all for now. I think project "getting her cleaned" is officially done. Next up is "proper lubrication" and "minor repairs", the machine has over 20 grease nipples, and quite a few things that show signs of wear..
I have also begun to think about moving the switch box from the table, and fix it to the machine, having it acessible close to the head. Would make a nice "control panel" together with my future DRO ::)
Questions:
What I allways refer to as ways, they are called ways, right? :scratch:

You're making good progress with that mill Trion, Keep up the good work and the brilliant pictures :thumbup:

Trion:
Thanks! I'll do my best :wave:
When I get around to buy a ER 40 collet holder, I'm hoping to be able to make some progress on the lathes ball turner aswell :coffee:
Bernd:
Trion,
First, nice job on getting that mill looking better. Looks much more user freindly now. :thumbup:
Second, yes they are called "ways".
Nice logical steps to getting a used machine up to home shop working order. Keep up the nice work. :whip: :clap:
Bernd
