Hi Eddy
I have a couple of questions about the wabeco lathe.
1/ It seems that there is only one lathe from wabeco that have a power feed of the carriage, and that is the D3000 lathe, and it is powered by a separate motor with potentiometer adjustment. All other lathe seem to use the lead screw and offer only two auto advance speed, which can only be switched by changing gears.
So : first, do you think it is important to have a variable auto advance feed? Is it OK to use the lead screw as an auto carriage advance, as it is on the other Wabeco lathe? I heard you should not normally use the lead screw for auto advance, but only for threading...?
Is the D3000 power feed physically separated from the lead screw, or is it using the same lead screw to advance the carriage, as on the other lathe?
2/ Do you know how many thread per inch the lead screw has? I heard that you can disengage your carriage from the lead screw while threading as long as the threading you are doing is a multiple of the lead screw TPI. This can be very interesting!
3/ On the D3000 I see the power feed motor control are on the extreme right of the lathe. When you are making finish pass, I wonder if you don't want to keep your hand on the feed control, in which case it can be quite a stretch to do so. On the other hand, if the power feed uses the same lead screw than the threading lead screw, you can leave the feed motor running and stop the carriage by disengaging it from the lead screw. What do you think?
4/ When threading, when you stop the motor at the end of the threaded portion of the part you're machining, does the spindle stop running rapidly? And can you reverse the engine right away?
If you know any video about machining with a wabeco lathe, I would be very interrested... Any more pictures or video of your lathe?
Sorry for so many questions,
Thanks and hope you enjoy your Wabeco
