whats the rapid speed on this machine

this thing must have at least 1g acceleration

[brothersocal]

2756 Inches Per Min. or 70 Meters per Minute.

just because a machine is built for high speed does not meen its meant to always run at high speed, it just meens it can handle high speeds. Big difference! look at race cars, they are built for speed, but will the motor last you over 100k miles running at redline all day long? no, the same goes for any mechanism. think of the ballscrews on these fast machines, like hobbie zones mentioned, i would like to see this machine 1 year later if it always runs like this!

@HobbieZones at 0:36 the feed rate is slowed down and at 0:40 there appears to be a G04, possibly to cool or clear the cutter. Machines that can cut like this are usually made to do so, high quality bearing and also internal cooling in the spindle. The cutter is not sticking out far so there is not a lot of pressure on the spindle in that aspect, also the rpm is probably up around 15k so chip load is probably no more than running a .5 4 flute at say 5k and a feed of 50ipm

[HobbieZones]

If speed counts then why at .36 sec do you cut air and at .40 cut some more air lets get the endmill on the part .

Want to see mill in one year if you run parts all day long like this POOR spindle.

Well as you can see in the video, its only running 1 part at a time, and the machine doesn't seem to be a pallet changer, so obviously the intention here is not to mass produce. I understand that in huge contract jobs every second counts. BUT I was questioning THIS particular set up. So you know, job shop mentality has nothing to do with this. I"m the manager for a manufacturing company, I know what matters and what doesn't when it comes to profits for a company. So don't assume.



[scooke4073]

@jtjoser I'm not talking 100 parts. I'm talking full blown lights out production. 24/7....pallet pools....300+ tools staged and ready to roll.  Trust me, every single inch counts. One second per cycle could potentially be several hours by the end of the run. You have a job shop mentality.

@scooke4073

Hey not to knock on your idea bro, but when you have fast rapids of over 2,000 ipm... you wont even see the difference in time for the Z axis to travel those 2 inches you have in your blocks, but instead your setup could be more rigid if you sit the vise to the machine table... do the math, at 2,756IPM, your machine travels about 45 inches per second... 2 or 3 inches is nothing. Machinist should never sacrifice rigidity for time!

[scooke4073]

@jtjoser reduces the distance from home to workpiece. Perfect for high production quantities

I was wondering why your vise was up on a block too? peace

[jtjoser]

Nice video! But Im curious, why do you have your vise lifted on blocks?
