It took some time to finish the first gripper because I was busy with other things but here it is. Jaws made from ck45.

And here I am on the design at the moment.
What is the correct angle for ISO20 taper? I mean what the angle of the spindle taper should be?
um. shoudlnt that have been the first step here?
taper for ALL steep taper type tooling, regardless of size is 7 in 24.
which means, your profile reference points for angle are are 3.5 units radially, 24 units axial. with an opening of 22.225mm (7/8") diametre.
Soo, does that make 16,5943?
i hope not. your tools will fall out.
it should be half that per side.
i assume you need the actual angle for manual lathe?
Hi again,
It's a CNC'ed lathe.
According to my calculation the angle of the line is 188.29715° however, I just tried to cut the taper on aluminium but it is narrower on the large size so there is a little play on the small side. What did I miss?
AL is not cheap :/ Can we see your sketch's dim or part's pmi?
al is cheap AF :P
better to screw that up than A2
this is also why you dont use angles. use the 7 in 24 measurements.
difficult to know what has gone wrong, without knowing you use 7 in 24 to start (and not some rounded off angle)
you must work at one of the spindle factories ive talked to.....
ah. Nah at our spindle factory we use A4 size sheet of paper rolled between our fingers to dbl-check tapper angles. The sign-off engineers prefer that entertainment over having to click those 4 buttons out of that Microsoft Scientific calculator.
Hi,
atan(7/24) makes 16.2602047083 degrees so half of the angle is 8.13010235416. So my angle will be 188.13010235416
I hope I'm good this time. Can you please confirm?
By the way, I don't know if I could directly enter "arctan(7/24)" to the angle text field in SolidWorks. I'll give it a try.
Getting the same at my end, measured from centerline mind you. Both 3.5/12 & 7/24 checks out...
If your CAD can't do math and arithmetic/operators it is not a CAD, its a scam
Bet SW can do formulas better than most others anyway... you should be more than okay on that side
Thanks
Hi again,
7/24 doesn't fit. There is still space in the small end of the taper. However I tried 8° 17' 50" and it appears to be the correct angle.
O_o
whats that in decimal?
curious why it wouldn't match up. I was certain all those tapers were the same spec.
thats 7 in 24.....
why cant kids math these days?
