Ok finally getting ready to break it in. I understand the 10 minutes at each speed and then 10 min in reverse at 2400 rpms to finish break in for spindle . But what about the break in settings for the gearbox my manual says alpha set to C and numerical set to 1 for the whole break in. Do I need to run it in some of the other settings , like say alpha A and B and numerical 2 and 3 to smooth up the other gears in the box? Aaron

Also wondering about the warning plate that says do not change between high and low while running I assume that means not changing between the gear box settings while running.
 
I have not cut any metal yet , am still waiting on some bits etc to arrive in the mail. But I have acquired most of my measuring tools, and drills and drill chuck and a live center. And I have to find some stock this week to practice on. Aaron
 
Hi AirlineRefueler, I have been changing gears on my g0602 while its running since I got it. Bear in mind mine is variable speed and I usually hover around the 500rpm, but have done at higher speeds without any ill effect. I'd say it will soon knock off any burrs left by manufacturing.

This is my belt position. Have not changed it in several years.

I assume you are talking about the QCGB. No break-in is necessary... or possible. Due to the low speed of the gears in that gearbox, you would have to runs it for tens of hours to "break in" the gears.
 
I agree with tmarks11, considering the precision of the components and the loads its subjected to I wouldn't even consider the gearbox as a candidate for run in. If I had bought a new $10,000+ machinetool (the sky's the limit), yes I would definitely consider a period of running in prior to heavier use. The manufacturer of such a machine would recommend a suggested schedule so as not to void any warranty. Bear in mind that the manufacturer may have already performed a specific breakin of say the spindle bearings in-house.
For a G0602 which I consider a tool not of spectacular precision until enhanced, warranty is voided as soon as I get my grubby little hands on it. Think of all the forum members who have bought such a machine and have modified it to a better more usable state. It would be interesting to see how many have voided their warranty. (is there a thread anywhere discussing this?)

Really? I never heard of a lathe that allows you to change gears on the gear box while the lathe is running. Does the G0602 have synchromesh?

Well, I assume the gears have not chipped or broken, so far... Spur gears are not meant to be shifted on the fly, and I would never even try it...
