Bridgeport Series 1 CNC

Hello,

I got the Interact into its place and started to clean.
Some photos. They show some wear on the slide that transports the table inwards and outwards at the arrow.
It is not so bad on the other side. The oil marks or scrap marks can be seen to decrease.
On a scale of 1 to 10 where would this amount of wear be put? (10 being terrible).
I don’t think it’s too bad. The ‘ways’ are supposed to be chromed on these machines. Is the chrome still there?

There is oil on the belt that moves the table from side to side. Is this normal? The belt that moves the table inwards
and outwards is bone dry.

There is a pile of chips in the cavity that holds the cog wheels for moving the knee up and down. I will have to clean.
What is the best way to get at this area. I am thinking to remove the motor that moves the table inwards and outwards.
I thinik you can get at the cavity that way. It’ s big job to take off the table.
The rubber mats or rubber sheets that keep chips away from the ‘ways’ were in a bad state. I suppose that’s how so many
chips got in there.
Would rubber car mats do as a cheap alternative instead of purchasing the real thing. They are about 26 pounds each. I need all three. I could get car rubber mats second hand from the car breakers yard for damn all. I could purchase new one’s for a little more that damn all.

There is a sump pump for coolant. An automatic (or hand pumped?) lubricator for the ‘ways’, and an oil/water mist system too, which is located on the back of the machine. Perhaps it’s a standard thing on an interact?

Have yet to plug in the generator and see if the Interact will go at all……
I had a bit of a job getting it into its proper shed and over into the corner. It’s no perambulator.

@ Les.
How much did it cost to dump the TNC 150 and put in a modern system (approx.)

I don’t know exactly what sort of TNC 150 I have. Is it a B or whatever. Will have a look. How would you know?

If I could debug!! I have an oscilloscope.
