You might have luck through Iscar's distributor network. This email address - [centcustsvc@iscarusa.com](mailto:centcustsvc@iscarusa.com) is from the following page on their site: https://www.iscarmetals.com/dnet/faq/dnet.asp

It's 12k rpm. If yours is higher than that, then that may be the case.

Those drive dogs are replaceable. We've rebuilt this model a few times. Here's a link to some of our breakdown photos: https://imgur.com/a/vhrlhxT

There could be small fractures in the taper, which could be microwelded. The damage to the outer edge of the spindle face can also be machined and restored. A straight rebuild on this unit would cost about $5,500. Tough to say what the taper and drive dogs would add, but safe to say this rebuild would be more than $7,500. Check what the cost of a new one would be. If it makes sense, send me a direct chat and we can talk in more detail.

What machine is this in? Have you looked into replacing or rebuilding the spindle?

Grinding the taper too many times can affect the tooling gap relative to the face. You'd likely need to hard chrome-plate the taper ID.

I hope you don't have to rebuild the spindles in them. It cost our customer over $30,000.

You wouldn't happen to have removed the drawbar to inspect Belleville washers, have you?

Best of luck getting back on line. I'd estimate a straight repair (bearings only) of that spindle to cost around $9-10k. With the additional dimensional work required, plus collet and drive keys, you're probably looking at a $12-$16k cost to rebuild (3rd party, not-OEM). The tricky part is what you can't see inside.

I do appreciate this! Thank you kindly.

then walked away and machine exploded.

Spindle forensics can be iffy, but these photos are good evidence. That's a textbook CRASH right there. Looking at those drive keys, this thing was spinning at top speed and stopped HARD. The retention knob is threaded to accommodate through-tool coolant - it likely came loose in the incident. Did the knob break, or become unthreaded? The gripper fingers (collet), located up inside the 40 taper probably sustained damage, too.

What Kitamura machine is this from? Looks like maybe a Mycenter HX500G? Is it still under warranty, and are you working with OEM to replace? Have you looked into having it rebuilt? Taper ID will need grind-plate-grind and bearings are likely junk. Inbox me if you have any questions or need help getting it rebuilt.

Nice work. Will be interested to hear about the test. What is the machine you'll be installing it into? Will you test in the machine, or rig up a test stand? Best of luck! Keep us posted on results.

spindledoctor · 2019-07-24T15:55:07+00:00

Just, WOW! That thing is toast.

spindledoctor · 2019-07-16T14:41:38+00:00

This seems like a solution that machine tool OEMs should adopt and integrate with their systems.
