anyone read the articles in Digital Machinist about making your own pendants? the guy that writes the articles sells kits here: Texas Micro-Circuits Mini-Pendant Kit
some nice parts, I'll be...
Job awarded, thanks for everyones response.
i just threw it onto a stock title block, obviously for a cosmetic upgrade part like this those tolerances aren't needed ;) I apologize if those scared anyone off.
Need a quote for an aluminum bracket.
Material is aluminum, it is a cosmetic bracket, so 6061 or similar should be fine. I've attached 2 IGES files, one with a chamfer and one without, I'd like...
just some quick answers, but:
1.) http://www.engineersedge.com/calculators/torque_calc.htm
keep in mind that the force exerted by cylinder will be pressure x area, so a 4" bore has about 12.6...
very nice!
i love that face mill, i didn't think the BF20 size machines would have the HP to use the 5", but yours doesn't look like it has any trouble.
Been quite awhile since I updated this thread, I'm waiting on selling the last of a batch of parts so I can pay off the toys I already got, then I'll be moving forward with this build.
I'll be...
good to hear, hopefully mine will get here next week then. I haven't done much with my mill for awhile, I spent too much money on it and my car, so have to cut back haha.
use an abrasive saw or a cutoff wheel in an angle grinder for hardened linear rails. once you get past the surface the stuff is easy to cut.
I got an email back from them, they are making a C34 for Geckos, so yes, you can use RJ45 to connect with the stepper/servo drivers. The link there is to one that works with the Keling stepper...
if it was me I would get a replacement motor overnighted from the place you bought the mill, and give the bill to the shipping company.
for the mild inconvenience of charging the battery, probably not worth the trouble wiring a power supply then :)
I've been doing a bit of research on the CNC electronics, and I might end up going with these:
C32 Breakout Board - I'm a big fan of the RJ45 connections for everything, makes it much cleaner and...
brilliant! I'll be on the lookout for a cheap impact.
if you get the right voltage impact, you could even hardwire it with a computer power supply or something.
it may be best to use a band saw to cut up your blanks prior to machining, to minimize waste. for rigidity, you want to use the largest cutter possible that will fit your geometry.
i dont see why you couldn't mill a shape out of steel to stamp/cut them out. you might need to play with clearances and the shape of the edge
thanks
I picked up a 4"x4"x1.5" block of aluminum today, going to start on the brackets for my car.
while i was at the shop, we did a compression test (88 toyota supra turbo, inline 6), and...
thats assuming the bearing are NSK or similar quality, you never know what they can do if they are cheap chinese junk?
also, mind measuring the motor shaft diameter?
i meant the spindle bearings, someone mentioned in another thread that their stock bearings were noisy.
so you figure about 2:1? I wonder what speed the bearings would handle. until we can get...
I'm curious if its the gearbox or the spindle bearings? thanks for the info on the bearings by the way. the 32906 seems to be a bearing used on motorcycle forks
so current update: expensive. I...
just a thought, but rather than making the slots big enough for a wrench, why not make them a close fit to the nut? if you machine it just right, the nuts would drop in, and be essentially captive so...
nice setup, I like the idea for the x-axis ballnut.
many people use them for a bolt on high speed spindle. the ones ive seen are usually mounting using something like a shaft collar, clamping on to the snout of the tool. i dont know if i would trust...
if you really want a fast spindle, look into electric die grinders down the road. they run at high speed, and the bearings are built to take abuse. you could make a mount for one that attaches to the...
that looks really good. so this just attaches to the drawbar (R8?)?
check EKs thread, he had to grind the ebay nuts to make them fit.
are the flanges threaded on?
I was considering picking up the 3/4" from glacern: http://www.glacern.com/em90
same reasoning as you, save the expensive end mills for finishing etc, as the inserts are only $35 for 4 from...
he has a drawbar, he stacked spring washers under it, so when he presses the up against the MAD, it releases the pressure on the collet, letting the tool drop out.
