I love seeing *real* machining - I’d actually never seen a real industrial fly cutter before. The contrast with the little piece of HSS sticking out of the little fly cutter for my mini-mill is hilarious by comparison 😂 Interesting about the differences in application making such a difference in cost between the two types of cutters. Also that the fly cutter’s lower pressure on the part makes it better suited for flimsy parts.
Thanks for watching and commenting Dave! Unfortunatly fly cutters get a bad name from the little HSS toolbit ones everyone is accustomed to so they dont take them seriously.
I’ve been making similar fly cutters that take cnmg 43x inserts for many years. A very versatile tool with a high rigidity head. Our shop had a stack of T1 bulldozer blade parts to machine. 6” wide .100” deep cuts and thick heavy chips throwing all over the shop. The self clearing nature of the fly cutter is not to be underestimated. By far a more economical tool in the right circumstances. The only thing to be careful of is the tram of the head as the wide cut seems to exaggerate the error versus several narrower cuts. Very good video sir
Hi William thank you for watching and commenting! It's hard to beat an inserted fly cutter for many of the projects we do as well. Many machinists dismiss the value of these thinking of the HSS tool bit versions that are so common and cheap. We made our first fly cutters to cut the inside of large copper weld guns for the auto industry, some of the bars had to be 4ft long to do the job. Once we mastered the proper angles it made the job easy and we were the only company that the customer would use because the quality and finish was so good. Glad to hear about your cutters sounds similar to how our came to be.
I have used dozens of each style over the years. We used one to get it close and the other for the finish cut. I use hight speed steel or cobalt for aluminum. Both definitely have their distinct use even though they do overlap on use.
with you cutting a deep slot, don't you get any pinching with that stuff and when it is on it's side isn't there any sag from the top leg and flex with the fly cutter cutting the top surface from the inside, effectively cutting and theoretically pushing the work up as it is cutting out? must admit nice bit of gear.
Hi, Thanks for watching and commenting! This material is surprisingly stable unlike some steels like cold rolled. It was designed for commercial aircraft dies and used for stamping the fuselages and wing parts. Where you cut it is where it stays. The company that made both the material and dies had a huge CMM to check the parts and I have witnessed them pouring the blanks because a friend of mine worked there and also cutting the dies on thier enormous cnc bridge mill. They sold out to another company a few years ago and I no longer have acces to the excess material but I wish I did because I have used it for many projects.
@@paulrayner4514 the company that made it had a polymer division and a machining division so it was an internally developed product that was only used for their own jobs. I think it likely is quite pricey to make but they did not sell it to other companies. We used to make carbon fiber fixtures for the auto industry and they had a chemist that developed the resins for a lot of applications including carbon fiber and this material. Great people but they got to retirement age and sold off the company. The company that purchased them I believe still does the same thing and they are only a mile or so from our shop but I do not deal with them.

I like your detailed look at these tools - very useful and revealing - thank you! Subscribed!
Thank you Stuart!!

Nice example. 👌👌
Thanks Patrick!

@@mvpmachine thank you for you reply. I have never seen anything like that before, I would imagine it would be quite pricey.

@@mvpmachine would it not be worth dealing with them, If you have a big enough customer base to warrant it
@@paulrayner4514 I have toured thier facility with the intention of getting some work but nothing ever came of it.
Didn't the fly cutting remove the radius on the finish fly cutting passes?
The fly cutter was backed of from the radius 1/8" inch prior to cutting the walls. Thank you for watching!
That material seems very interesting, and awful all at the same time. That dust looks nasty
Thanks for watching! It is a little difficult to deal with the dust. I am glad I only occasionally work with it.
