Tube cutting - where to get the hss milling cutter?
La Stella Celeste wrote:
Thanks Ted - have just spent an hour and a half googling the milling cutter that you suggested or something similar. Do you have any suggestions as to where I might look? "ted frater" wrote in message ... La Stella Celeste wrote: Can anyone offer any suggestions on high-volume tube cutting? I made a jig and can saw by hand fairly fast, but I have several thousand tubes to cut and would like to speed up the process. I am cutting aluminum tubing - 3/16". I tried riggng my flexshaft like a small table saw and tried both a cutoff wheel and a narrow sawblade specified for metal, but am getting the metal chewed up and sheared off. I am holding the tubing in a jig to hold it steady while feeding it through the blade and it is still not working well. Has anyone had any luck with other methods? Thanks! I built a table saw as follows many years ago. use it for all sorts of precision cutting. Heres how. get yourself a 1/3 hp induction electric motor running at 1440 rpm. No faster.mount it on a wooden base. on the shaft usually 1/2in dia mount a shaft extension that has a shoulder with a 1/2in threaded extension. onto this fit a say 20/1000in high speed steel milling cutter 2in dia. and 1/2in bore 24 tpi make up 2 pieces of say 4in by 2in par( planed all round wood) also fitted to the wood base, screwed from the underside ofcourse. Next get a 1/8 in piece of brass or steel to make up the table Mine is 4in by 4in.. screw this down ( countersunk screws of course.) to the 4 by 2 in so that the saw protrudes by 3/4in through this plate. youill need todrill a hole then saw the slot with a suitable piercing saw in the right place.. now make up a fence out of say a piece of 1in by 1in angle with a slot in it for the hold downcscrew, obviouisly threaded into the table. so you can adjust the gap between this and the saw blade. You need to use a candle as a lubricant between every few cuts. Or bees wax, smells nicer! also you need to support the tube your cutting inside a piece of wood say 1in by 1in by 8in long with a slit in it so both the piece thatslong and the short piece are contained inside a drilled hole almost right through, Push this piece of wood up against the fence using the tube and youll cut hundreds an hour..If the hole is a few thou larger tha 3/16ths in the cut off piece will fall out. this will prevent the snagging and tearing your experiencing. Build it well and youll use it for all sorts of cutting I made it primarily for accurate sawing of hundreds of jump rings. the other day I had to shorten 200 potentioneter shafts for an electronic co. they were all done in 2 hrs the above way at 75cents a time. they wanted them the same day. Ted Frater It depends where you are and how near or far that is from a general engineering area such as an industrial estate. Now the milling cutter is a standard one ,here at any rate, and should be avauilable fron any good engineering supplies co. ie one that sells drills milling cutters and lathe tools. etc. Over herein the UK and for that matter throughout Europe there are manhy of these co's supplying the ehgineering and machining trades. Look in your localyellow pages and do some phoning around. Youll also need the arbour to support this blade. Start with the motor first then work out from that. Have you a vernier gauge ? to measure the shaft dia? |

Happened last time I did it too. Been so long that I forgot though. Anyway.
The link was to the first of 10 or so pages of HSS "slitting saws". Go to the page and use the "keyword search" function at the top of the page. Type in "slitting saws" and select your poison. -- Don Thompson There is nothing more frightening than active ignorance. ~Goethe It is a worthy thing to fight for one's freedom; it is another sight finer to fight for another man's. ~Mark Twain "Peter W..

Even though my orders are always small, I feel like they treat me as if I am General Motors. $25 minimum order. Not so, in my case. No minimum orders required. I have ordered items for as little as $2.00 (and paid shipping charges of $8.00 on that) -- Abrasha http://www.abrasha.com |

I took the minimum order data just from their web page. It's been a few years since I last ordered anything from MSC, so Ididn't recall the actual experience. I wonder if web orders are treated differently than phone orders, or orders from established clients or something... Peter |

Tube cutting
Celeste, Go to a local hardware store and purchase a small tube cutter. The
kind that is used to cut copper tubing. Should be under $10. Mark your tube with a felt tip pen your desired lenghts and cut away. This method will produce rounded ends however. if you need flat ends you could do a little grinding ...tedious. If it were me and I had to cut thousands of little tubes, I would embed several dozen long tubes in plaster blocks and use a band saw. You would have to experiment with the plaster to get the formula of one that disintegrates in warm water. Good luck,Will E. "La Stella Celeste" wrote in message ...
