We just ordered a new Mazak VCN 530C, looks like I will be recommending a few more hydraulic holders! ha!
Great job.
I'm still baffled how well weldons work... except groove dimensional accuracy since it's a slip fit
I would love to know why shrink fit was at the back of the pack...... I always hear it touted up. Great video
Pretty sure the overall tool length was longer than it should have been. Slightly unfair testing.
2nd, even if it was a worse tool holder choice for full slotting. Half the time, you likely don't want to be full slotting. The shrink-fit's main advantage is reach ability into deep places. Great for 5 axis machines, that usually require crazy stickouts.
It looks like the tool in the shrink fit holder was sticking out a lot further, which would explain the noise and rough finish. Not really a fair test if they aren't the same length from the holder
On second look, maybe it's just that the holder itself is long and skinny
I agree with you, i would not choose that long tool.for a slot.
@@MarkDonerSD yes there are bigger shrink fit toolholders. This test was unfair
@@ipadize ehh maybe but most of the heat shrink holders I've seen look like that and are meant for creating longer gauge length tools so they can access hard to reach features. Would a stubby heat shrink work better, probably, do they exist idk.
Tool pull out 2.2005 mm, What das actually mean. Throw away the job?
Weldon is ok. Good job.
Have you tried power grip?
For full slot - is Weldon ok, for side slotting need Hydro od ER and 2-3x variable helix. Thats all Fox.
If you are using a scientific approach, why there is no standard deviation in your results? And a quick comment on your tool pull out results: I think there was no pull out a the Hydraulic Chuck, Weldon and Shrink fit holder. That was just the tool heating up an therefore you milled a deeper slot at the end.
Greetings from Germany an keep on producing videos :)
It had better than 2mm of tool pull out. That's a lot to blame on heat expansion. Definitely the tool moving in the holder.
900 STX 2mm on the er collet chuck
You Not Mention Of material Doing this machine & tool with Shrink fit with Aluminum Material This is possible ,have you try with the material D2 hardness -52 HRC with this RPM & VC with this Vf also DOC
Have you tried Centro - P holder?
this test is hardly conclusive.
