Hi - I am running a VF Haas with TR160 Rotary, doing indexing and simultaneous work, obviously the work is pretty small, and usually dont need too much reach. Standard Issue Techniks ER16 X 4.00 covers most jobs. We run some schunk hydraulic TENDO EC's wherever we can fit the larger diameter of that holder. We like these a lot, but for the times we need more clearance / more reach, I go for the ER16X4.00, but sometimes I have bad runout, usually coming from the collet / collet twisting or deformation I believe. I can reclamp / reorient the tool and can go from .0008" TIR to .0002"- SOMETIMES.
I have looked at the SK holders, also heat shrink, as well as just higher quality ER collets / nuts with the bearings built in for less twist (we currently run standard issue Techniks ER holders). I started buying the haimer collets and saw some difference there.
What do most of you go with for low runout >4" Gage length holders?
I'm going to try a few shrink fit and see how that goes.
I was also wondering what the consensus was on Maritool SK16 vs Lyndex Nikken SK16? Comparable quality wise? I saw on the nikken brochure they brag about wire edm'ing their collet slits where I did not see Maritool brag about that, may not matter much if at all.
