Who makes this single insert flycutter
I bought a set of flycutters on ebay, and I'm pretty sure these are the
ones for which a company posted a special here a year or two ago. Thought I'd saved that post and/or URL, but cannot fine either. Does anyone recognize these flycutters and have the URL? Need to buy some inserts. Here's the auction link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7540118752&rd=1&sspage name=STRK%3AMEWN%3AIT&rd=1 Thanks, Jon |

Jon,
Can't say I recognize them...but they are radicaly differentthan any other fly cutter I've ever seen. I'll ask around & see if I can help you locate the inserts. A couple of ??? for you though (I'm interested here): 1.) Do the inserts glue or braze on? I didn't see anyplace for a screw. 2.) Being round...is the cutting edge of the inserts 360 degree rotatable...for a cutting edge around the entire surface? 3.) Are these things a better roughing cutter than they are for finish work? -Wayne- |

According to :
Jon, Can't say I recognize them...but they are radicaly differentthan any other fly cutter I've ever seen. I'll ask around & see if I can help you locate the inserts. A couple of ??? for you though (I'm interested here): Rotary Technologies: The URL for the cutter inserts is: http://www.rotarytech.com/inserts.ph...sID=7&TypeID=0 1.) Do the inserts glue or braze on? I didn't see anyplace for a screw. There is a single screw in the center. 2.) Being round...is the cutting edge of the inserts 360 degree rotatable...for a cutting edge around the entire surface? Pretty close. IIRC, there are 12 rotary positions in which they can be mounted, and then you can flip them over for another twelve surfaces. Actually -- checking the web site, it depends on the depth of cut. Depth of cut : inch .03 .12 .25 mm .08 3.2 6.3 indexes/insert: 24 12 8 So -- the deeper you cut, the more of the edge you wear, and thus the more positions it needs to be rotated through before it reaches the next clean cutting edge for the full depth of cut. 3.) Are these things a better roughing cutter than they are for finish work? They can produce a beautiful finish with a sufficiently rigid machine. But, as you can see from the table from their web page above, they can be used for up to a 1/4" depth of cut, if roughing is your game. But -- before you go overboard about these, look at the prices for the inserts, and the minimum orders of a box at a time. The 1/2" size can range from $196.70 (for a box of ten in one grade) down to $53.11 (three per box in another grade). So -- it is around $17.70 -- $19.67 per insert. If it works for you, and you're getting paid for the work, it can be worth it. Enjoy, DoN. -- Email: | Voice (all times): (703) 938-4564 (too) near Washington D.C. | http://www.d-and-d.com/dnichols/DoN.html --- Black Holes are where God is dividing by zero --- |

I remember reading an article in an old edition of Model Engineering Workshop, where a contributor described a simple way of making these from tool steel by tapering and parting off several from the correct size rod. It looked effective. Might work for you. Regards Tom. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

I dont know who the manufacture is..but Ill can tell you who did the grinding and finish work. It was All Diameter Grinding in Orange, California. Ive been giving these things away for years, sans the inserts as I got several hundred pounds of the rejects...out of round by .0005 etc. Ask for Marv or Jeff 714-744-1200 Gunner "Pax Americana is a philosophy. Hardly an empire. Making sure other people play nice and dont kill each other (and us) off in job lots is hardly empire building, particularly when you give them self determination under "play nice" rules. Think of it as having your older brother knock the **** out of you for torturing the cat." Gunner |

So -- it is around $17.70 -- $19.67 per insert. Which works out to less than a buck per index. But I lucked out, turns out I have the older bodies that don't have the hex star. Since I bought these strictly for light facing operations at shallow depths of cut, I can index the inserts only as far as needed to bring a fresh edge into play, potentially getting even more "indexes". Just got off the phone with Rotary Tech and they confirmed the current style inserts will work fine with my holders. I'd guess one box of inserts will probably last me many years, though it sure is a steep initial purchase. Jon |

Ran the big one up to 3400 rpm and no noticeable vibration at all. Sure wouldn't try that with the type that use brazed lathe bits! I regularly run my Bridgeport @ 4200 RPM with that setup. No problem. Even with the tool extended somewhat. Harold |

None of the larger ones can run at that rpm without vibration from being out of balance. Always intended to do something about that, and just did, by replacing them! Jon |
