r8 quick change collets

[Brento]

So i recently heard about the quick change set up for the r8 collets. My set up now is to use er20 collets in a r8 adaptor. Should i just stay with that design or is the quick change better. Im only a hobby machinist.

Which quick change system are you referring to? I use the Royal EasyChange system and love it. No tools required to change cutters. It's not cheap, but just fantastic. This is the system I use: http://www.royalproducts.com/product.cfm?catID=11

And here is my set of tool holders I use with the master chuck - set includes facemill arbor, slitting saw arbor, about 20 different end mill and shank tool holders, three ER32 chucks, three drill chucks, etc.:

Ive seen this style and the mach 1 style. But as a hobby is it worth the price or am i better with doing a collet system i have in place already which is using er20s in a r8 adaptor im gonna be using a grizzly mini mill.

What are the perks or negatives to using the quick change style

 

[Ulma Doctor]

you heard the negative, the high cost...
the perk is fast tool changing, which means $$$ in a production environment
your er20 system already has minimal run out, you may wanna stick with what you have.
you'll need to figure out what your time/money threshold is, if you have the itch to go quick change
you options are going to be limited in R8, and bring money when you wanna play!

For the mach-1 style can anyone tell me what the collet facing fixture would be for?

It is for facing the back of your collets to length to work with that system. Per the video on there site.

Mach-1 seems to be pretty cool but very expensive. I’ll have to put these on my wish list for in the future.

Only you can answer if it's worth the price. The master collet costs about $750 and each tool holder is about $250 if you buy it new from a US distributor. This stuff is not inexpensive - I've built my set over 15 years scowering eBay and buying directly from a supplier in the UK (costs half what it does in the USA). I probably have $5K wrapped up in my Royal QC system components. I stared with a different QC system called PDQ, and quickly sold it off and moved to Royal to get better tolerances (TIR).

You might want to consider a power drawbar to make changing tooling quicker and easier. The Mach-1 system is essentially a variation on a power drawbar setup. There are lots of videos on YouTube about building your own power drawbar. Here are a few:
