I make small components. Watches from scratch specifically. So accuracy is more than half my time. Is it worth upgrading to hydraulic Chuck tool holding on the mx? My spindle bore is sheer perfection with no detectable runout on the bore. I currently use er16 5micron collet tool holding and runout is 3-12 microns consistently. (You may have seen my extensive post “runout mystery” which is still in progress.) I am wondering if the hydraulic tool holding makes sense for the mx or is it something Better suited for higher end machines. I cut small parts with small carbide end mills 95% of my work is using .8mm - 4mm end mills. Mostly cutting brass and drilling holes .4-3mm diameter.

Having to use a torch is always annoying, I’ve never seen any huge benefit of heat shrink holders (except cost) over a couple of hydraulics for finishing, end mill holders for roughing, and ER holders for general purpose.

I have a couple of Maritool hydraulic chucks and reducing sleeves that I use with my MX. These hydraulic chucks are REALLY nice since there is no fiddling with reducing the runout like I always have to with ER collets. With the Maritool hydraulic chucks I get cutting tool runout down to a couple microns with no fuss.
Please Note: I do pay a lot of attention to the cleanliness of the hydraulic chuck and cutting tool when loading the cutting tool into the hydraulic chuck. I clean the shank and hydraulic chuck with denatured alcohol and use clean dry air to dry the chuck and cutting tool. No dust, no lint, very clean.
