    x3 startup suggestions needed asap

    Sorry if this is miscategorized but Im on a deadline, not sure where else to post it. I usually do all of this research over the course of weeks but Enco has a free shipping and 10% off sale that goes on until tomorrow. This is my tentative list for stuff to buy, and was looking to see if anyone had substitutions. I'm trying to go somewhat cheap for now, but am willing to spend some extra if the quality is that much better for the higher end stuff. I'm just getting back into machining after a 5 year leave so I need to get back into the grove of things.

    Im converting an x3 and need tooling/etc. Starting from scratch. Going to be doing aluminum and plastics, maybe some mild steel once in a while.

    Will this fit the grizzly x3 table?

    This is only 150 without the discount, so I definitely have more wiggle room. I was expecting to pay around 3-400, but definitely want to keep it as cheap as possible.

    What I havent found yet:
    A decent affordable set of parallels.
    Cheap set of drillbits
    center drills
    Cheap/decent electronic calipers
    More/different endmills?
    I really want one of those dial gauges that you touch off to set your z-zero-- i forget what they are called.
    Anything I missed?

    What I have or am buying somewhere else:
    GMT 4" vise, unless there is a great price on an enco one that is quality, but the 4" is on sale for 220 so i doubt that will happen
    mech calipers
    mech micrometer


    Thanks in advance for your suggestions and help! Hopefully this might help someone else that's in my situation.

    I'm only begging my CNC adventure but have been non stop machining for hobby (and some profit) since high school. A few things i'd recomend are

    That clamping kit is not going to work, you need to order the 3/8ths' stud sized kit, then you'll have to put the "t-nuts" into a vise and mill the smaller portion of them a little thinner as the X3 table slots are metric sized and just a bit too small for the t-nuts to fit, but the slimming down is a 10 minute job at most and is in no way going to be "half-assed" or anything like that..i've seen people ranting about it, but hell, it beats making them from scratch and you'd spend more time on google trying to find a set thatfits un-modded than it takes to mill a little material off each T-nut and call them good.

    1.) Going on ebay and ordering a "batch" of endmills off some one, try to avoid anything chinese, as i have watched about every import end mill i have go from new to trash can within a few minutes of machining anything other than aluminum or plastics (maybe overstated but i'm sure you catch my drift) - You can get a set of say 30- 50 end mills for about 1-2 bucks a piece ordering on ebay (and believe me after working there at one point i don't really care for ebay in general) but sometimes you jsut won't get the same deal elsewhere... Also, look for a set that ha some irregular endmills in it as well as some that have either the TiN (gold) or AiTiN (black/blue) coatings. I've found that there's a LOT of times i need a longer endmill than what's typical, and now watch for long ones when buying that i can just slip further in the collet for regular work and when i need them really rigid

    2.) Get yourself a "screwless" or toolmakers vise, You can get one that opens about 5 inches from either Enco (IIRC) for about 100 bucks or so, they are nice because they are low profile, have great clamping force without the jaws moving and mis-aligning your part. And generally you can get the same work-holding (jaw opening) in a much smaller vise. i am a newb to CNC but from what i've been told the screwless vise is what's preffered in a CNC setup, but having no formal experience with CNC to give my own opinion i can't say for sure, but i will say that i love my screwless vise, and i want another one that has the 5" opening to replace my current vise thats used on my machine most of the time

    aside from HHS endmills i've absolutely fallen in love with the cobalt and carbide material end mills as well as the coating which i belive is abreviated AiTiN - Black almost blue'ish coating (not talking about the indexible types but regular endmills made from carbide and cobalt) they last through hard material cutting without flinching but require some skill and thought because they can chip rather easily if you have slop in your table or even too much play in your Z gib/or forgot to lock the Z in place when manually milling. they can be pricey, but get yourself a 1/8th, 1/4, 3/8ths and 5/16th's in carbide with the AiTiN coating on them and you'll be in hog heaven ( i rarely have much use for endmills 1/2" or larger, unless i'm just roughing stock to shape, or using a facing mill, so buying multiples in the smaller sizes will really pay off, especially when you break a little 1/8th one and can't finish the job with anything larger)

    some more things:
    HF has a black case with a HUGE selection of TiN coated drill bits (all the small fractional bits, as well as the inch and letter sized in the most common sizes) and they are pretty cheap. they have lasted me a LOT longer than any HF endmills and other cutting tools, and with a drill bit sharpener you can refresh them for a long time to come.. now days when i break a bit or need something stronger for SS and such i go to the local nut-n-bolt supplier and buy cobalt drill bits, very tough, long lasting and go through stainless like it's nothing!

    They also have cheap digital calipers, and one set they have will read fractions which is nice when you need a fractional bit and time and use have worn the markings off some dril bits (i have so many drill bits that i have a cup for small ones and a drawer for larger ones - these are ones that are "extra" and don't have cases to organize them) sometimes they're on sale for 10 bucks..also if you order bearings for anything, buy them through VXB and you get a free caliper with your first order of 50 bucks or more and they are the same "type" but much better built versions of the cheapo HF digital calipers (i abuse the HF ones, and keep my nicer ones inside for reading "clean/finished" parts)

    Grizzly has center drills from 4 for 5 dollars (import) to 2-3 bucks each for better ones but probably still import (can't recall)

    Also, get yoruself some dovetail cutters and some keyway cuters, although rarely used in my work they are invaluable to have when you need a small slot in something and can do similar work as say a 3/32 endmill, but can feed a lot faster in the same material

    here's a decently cheap set of parallels http://www.littlemachineshop.com/pro...gory=988300808

    also, V-blocks are always handy to have, i have a nice set likethese (different maker - non-import) http://www.littlemachineshop.com/pro...gory=988300808

    the one thing you didn't know the name of is a "Z axis tool height setting gauge" (probably ha shorter name but that's what i know it as) here's a decent one at LMS http://www.littlemachineshop.com/pro...gory=988300808


    if i think of more i'll updatre my reply

    Thanks! Ill look into all of that. I have experience with the toolmakers vise and it was kind of annoying sometimes but i never had a part come out of one (which i have on the screw types).

    YEa, same here, i don't use my screwless as much ( built my own from plans on the net) but when i have used it i have never had a part slip as easily as they do from my normal table vise that i've been using since buying the X3.

    I'm surprised no one esle has chimed in to add anything. I'm really interested in how your build comes out as i'm just undertaking mine as well (just holding off untill i know the software well enough to justify the purchase of the ballscrews and electronics on some one elses dime)

    best of luck!

    I have a screw type vise, but have been in the market for a toolmakers vise
    where are you finding the $100 vise with a 5" opening?

    Enco has them, but they were $180 to $340

    I would like to have one, but my screw vise is ok if the buy in is close to $200

    Thanks
    Duke

    Search for Shars on Ebay. I got mine for 80 not too long ago from discount_machine

    edit: price seems to have gone up a little although this is a 5" one with 6" opening
