    I am not sure about the light but I "think" it is always on. As for the conveyor that is what your 3-month warranty is for.

    I already contacted the seller.

    I also found out the x axis way covered is in bad condition , that's another thing that has to be repaired

    Take a close look at the rear Y axis cover, that is the one I would think is in the worst condition because of how many small segments make it up. Which X axis cover?

    Take good care of that spindle, I shipped mine out to the rebuilder last Friday. They are a fairly expensive spindle to rebuild, and being dual contact it really narrows down who can really grind them.

    L/h side x axis cover , the y axis seem both good!

    What sort of cost are we talking about for spindle rebuilt?

    At least that is the simplest cover on the machine.

    $5500-$6000 to replace the bearings. A couple hundred more to dust off the taper. Removal and installation are on you. Removal is fairly easy, installation is pretty involved.

    I have a question for you. With the machine idle or off grab the spindle nose or tool holder if one is in the spindle and rotate it back and forth quickly. Do you feel any slop? The spindle to motor coupling is basically a gear keyed to the spindle and a hollow shell with gear teeth in it that clamps to the spindle motor and fits over the gear on the end of the spindle to drive it. Mine has noticeable slop in it but it is worn out from useless morons installing the spindle the last time.

    If you haven't been following my spindle rebuild thread here is the link, long version since the forum software isn't working, Spindle rebuild on my 2001 Kitamura, a how to with some questions.. Check out post #42. There is a 7mm hole on the opposite side of the spindle from the coolant nozzles that is the air/oil exhaust vent. Your bottom bearings are about 2" up it so DO NOT BLOW ANYTHING TOWARDS IT AS IT IS VERY EASY TO BLOW COOLANT AND CHIPS INTO YOUR BEARINGS!!!! I am going to come up with something to guard against this as I found metal chips in with my bottom bearings. Unlike the spindle nose, there is nothing to keep chips and coolant from going up the hole unless the air/oil air is coming out.

    Engineer was in today, chip conveyor has been sorted , same as way cover , we sort of refurbished it.

    I will probably send for a proper refurbishment soon.

    Everything seems ok now , except I came in this morning and the wall socket, was not working anymore , not sure if it's because I am running the machine transformer which is rated @42a on a 32a wall socket?
    Strange as it has been ok for few weeks.
    Unfortunately the total power I have available for my unit is only 50amps.

    I have been running Robodrill, the Kit , and 10hp compressor without any issue last weeks , hope is just the socket defective

    Regarding the spindle I did that check you asked me and I couldn't feel any slop.

    Wow, that's a lot for 50 amps. Thanks for checking the play in your spindle. I am thinking I will be getting a new drawbar and spindle coupling, but will wait to hear what Setco says.

    Power permitting, I can't wait to start cutting some metals.

    I have many small aluminium parts to do , I am not super familiar with pallet changers, but for my application I think is worth

    Start searching! Hennig rebuilt both Y-axis covers before I bought my machine so I could get new wipers from them. Both of my X-axis way covers are original and although the wipers are still there they do need to be replaced. Kitamura here was useless for that item, they only sell the complete way covers, not parts. WTF!

    I have RTV siliconed a dam on both X-axis covers to keep most of the coolant and chips off of the way covers. It's two-piece with aluminum flashing screwed to it to extend the height. It has been like this for several years and no problems from it. I also hold a sheet of aluminum along the back of the table with magnets to do the same for the Y-axis rear cover.

    Have you pulled the way covers back to inspect what is under them? This is something you REALLY want to do before your warranty expires in case your ways got rusted. Make sure you have the special grease to seal them up with when you bolt them back on. No seals and sitting for so long would make me a little leary.

    The ways they look very clean to me, but I could be wrong, when I have a chance I will take some pictures.

    What special grease do I need?

    I spent all day setting the machine up, I actually noticed the slop you mentioned before on the spindle.
    I also noticed the bad finishing on the parts , so there os definitely something wrong with the spindle!

    My slop is extreme but I only recently noticed surface finish issues with my face mill that may be from my mill, but I think it was my spindle losing preload not the slop in the coupling. The noise coming from my spindle changed about the same time I started noticing surface finish issues on a part that I have made a lot of over the years.
