    Inaccurate/non-repeating pickups on Makino U6 wire edm

    Thank You for the detailed response Brian. I had cleaned the k-roller this morning but I will grease it tomorrow. I did also clean the pinch rollers but will verify that they rotate smoothly. For the wire I am using a .012" hard brass wire from PremiumCut (I put a fresh roll to make sure it...

    Inaccurate/non-repeating pickups on Makino U6 wire edm

    I did a plate width on a gage block in the x and y and I was getting much better results within .0005. It could be whatever issue I'm having is magnified when I do the 3 point. Unfortunately, I do have to use the 3 point pickup for a lot of things I do.

    Inaccurate/non-repeating pickups on Makino U6 wire edm

    I've been having trouble with my wire pickups. For example if I do a 3 point pickup on the OD of a machined part that measures 8.125 I'll get a measurement of 8.118 and 8.134 on back to back pickups in the same spot (submerged and high accuracy). I've been trying to rule out different...

    Drilling 316L SS .125"D x 3"lg (24xD)

    Drilling 316L SS .125"D x 3"lg (24xD)

    Yes the pilot drill will be at .126. Thanks for the entering slow with M04 tip, I'll try that although I don't think I can switch from flood to thru coolant. I was just going to use thru coolant with a sealed collet. I think the coolant pressure is around 140 psi.

    Drilling 316L SS .125"D x 3"lg (24xD)

    I have a job coming up that is going to require drilling a .125" hole 3" dp in .75" OD 316L stainless on a CNC lathe with y-axis and live tooling. I plan on using a Nachi carbide 25D drill with thru coolant along with the recommended pilot drill in er collet holders. From what I've researched it...
