    I sure thought that is what I was told, which ended my interest in them. It was back when they were offered so my memory could be wrong. Fanuc sure did strip them down!

    It sounds like you were traveling in the X direction when it crashed for how the head is off. My guess is the head twisted on the blocks, I have seen this often on linear way machines. The rails...

    As for 4th axis capability, it is my understanding that the control is capable of up to 4 axis total, with X, Y, Z, and the turret using all four up. This is why it is not capable of a rotary 4th...

    I am amazed at what the Harvey 5 flute mills for aluminum can do when I fuck up and bury them. I haven't tried slotting but short of that I haven't broken one yet in years of use so 5 flutes are not...

    I use suction hose from the irrigation supply. 6 years and good as new, with my coolant, yours may vary. Don't overthink this, it's a crap shoot. Just like some coolants and paint don't like each...

    Maybe a dumb question but I have picked the wrong oil a couple of times now and they all need oiling again. I have 3 fans with sleeve bearings that I have to oil once in a while, shafts are 1/4" to...

    Knowing what your application is I suggest Harvey #61812-C8, it is a 3/16" x .285 loc with .005" corner radius TiB2 coating. This is one of the tools I never take out of the carousel. I am using...

    I use 1 or 5 micron 7"x32" bag filters from McMaster-Carr, sewn seam trade size 2. They cost $7.90 and last for 3 months. The heads are around $20. I will never go back to unfiltered coolant. No...

    When I bought those 3 years ago I found out they are defective, the 3/16" mill photo is NOT of a 3/16" mill. The scallops are too big/deep so the cores are tiny making them very fragile. Garr makes...

    Contact Leadwell or their local-ish distributor to get it. If an email doesn't work then try by phone, or phone first. They will want the serial # of the machine.

    PVC is quite similar to ABS, perhaps a tad softer. Both are fairly abrasive to machine so your HSS will lose its sharpness quickly. On an ABS production job I ran a 3/4" carbide mill at 3k and...

    I just looked around some and didn't find better prices than direct, but I didn't look very hard. What voltage will you need? I got my buck transformer from PP when I got the converter.

    What the machinist thought was a tight tolerance was way off of making a useable part. To be honest I don't see some clear distinction between toolmaker and machinist, I think there is a lot of grey...
