Evening gents,
I've got some THK HSR15's that I'm using for a build.. Only trouble is they're 0 preload blocks. I'm looking to repack the blocks with larger balls but can't figure out a good way to
accurately measure the diameter of the current balls. Seems like I'd need to get down to the micron level (0.000039 inch) or at least one tenth. Also, my micrometer is only good to about 5 tenths best case and while I'd love to grab a Mitutoyo digital mic (which are accurate to a micron -0.001mm) I don't really have the funds.
I've looked at setting up a LVDT system but I fear it may be the start of another really long project (which I am admittedly famous for) that gets me further from my initial goal.
So question time: 1. Are there any documentation that specify the diameter of the balls in a THK HSR15 block (I've heard it was a trade secret but ya never know!)
2. Assuming the response to question 1 is a no, is there a place ya'll are aware of where I could get a ball accurately measured so I can go about experimenting with . larger sizes and preload etc.
And for anyone considering this here are a couple interesting reads regarding this exact problem:
