Well I was thinking if I start the Shizuoka retrofit I will do the lathe in the same time since I have to deal with the same kind of stuff anyway.
So Here we are, got this Hardinge CHNC cnc lathe for retrofit and started taking off the servos today to see what's going on.
Now after i took the servos out , same thing as the shizuoka , tach and resolver for feedback.Looks like all the 80's machines were this way, no encoderrs .
Check first pic of the tach, resolver assy
Now the best thing is that there is enough space to install a shaft encoder .
unlike on the mill.You can se in the picture the 1/4 inch shaft that the tach/resolver assy is using to get the feedback off the ball screw .
I will have to find a nice 1/4 shaft encoder.
The problem that I have is the dc motor.
Both work but the labels were off so I have no ideea what kind of motors they are.They are the same but both had missing labels.
Anyone here has any ideea what's thje specs on these motors??
I attached a pic of the motor.
It's the original motor that came with the lathe.The lathe is around 80's chnc4 model , at least that's what I heard from the owner before.
Any info will be appreciated.
Thanks
