I work in the aerospace machining industry, its fantastic.

Probably just a chain fixture or chain cradle fixture.

Most of those operations are fine I use a tool that I can run at 250 m/min at 1.5mm fz and 1.5mm ap it will hold on for a long time and no cooling needed its a tungaloy doofeed mill and it's my favourite tool use it all the time uses all the power of the macine but strangely stil low forces in the workpiece if you are able to I recommend it very much great allround cutter TXN06R063M22.0E06 Dont know how much it costs but whatever it may be it's more than worth its prise Even the inserts thay have 4 cutting edges and I get 1 month out of them before I have to change them You can even do pre profiling

I’ve found that carbide drills are usually good for 200-300 holes

@@SuperScottie3000 In what material? I've heard of carbide drills going many thousands, if not tens of thousands of holes.

Oakwood Machine Works yes, I’ve seen smaller solid carbide drills go thousands, I was mostly talking about large (1.5”+) index drills like in the video. They seem to wear out much faster than say a 3/8” solid carbide drill. Most of my experience is in hot rolled mild and alloy steel.

@@SuperScottie3000 you are clearly using chineesium grade carbide man... , that or exotic materials...

😳

Having worked with seco tools for a few years now i can say, they are one of the few companys whos tools you can actually reliably push hard as shown in promotional videos.

Yup, all those fast starts and stops have to add up. If your part price includes replacement of the machine, you're good. The hidden cost of machine replacement is not only its sticker price but also all the man-tax-hours of the labor that makes the money used to replace the machine.

Depend on how long is your warrancy

Stevens Engineering in Arizona makes chain fixtures.

Check out edge precision here on YT. He made some nice anvils.

It's because of the insert, the insert is a ceramic insert and not your typical carbide insert. A typical carbide insert shears the material away. Cutting through material like a knife on a microscopic level. whereas a ceramic insert melts the material away, so running coolant is the complete opposite of the ideal cutting condition. Ceramic inserts also have poor thermal shock resistance so even if running coolant was possible the insert wouldn't last very long.

@@rlsweeneyjr1 Hi Richard, the chemical properties produced by ceramic milling/turning are undesirable, for that reason it's not really used for finishing and I'm not 100 percent sure but I think it's rarely used for semi finishing and instead just for hogging as much as possible off a tough material like inconel.

@@rlsweeneyjr1 I used to be a machinist from 16 - 25, then I started my own company CNC programming all over the globe, then I became an applications engineer for one of the largest CAD/CAM companies, I'm still working for the same company but I'm a projects engineer mostly doing post processors.

@@rlsweeneyjr1 no you don't factor in thermal expansion. If thermal expansion was a major problem, tools would therefore break/deform and the workpiece would likely almost always be out of dimension according to the prints

@@Limosical but also depends on material being cut
