Would a small 1hp lathe be able to drill a 12mm and 20cm of depth in 4140 steel? assuming the proper drill bit and speed is used?If not what's the minimum hp needed?
Yes
>>2782393fo shizzle?
>>2782397Just keep it slow and oiled and yeehaw, stick it in grandma
4140 is hard af, you're just gonna keep burning shit up
>>2782390You can work your way up
>>2782390>4140 steelYou can't drill that, it's literally metal
for normal, human people: he's talking about 1.7225 steel
>>2782390please buy a real lathe I have one of these and it's worthless for steel
>>278239012mm (.4724") x 20cm (7.874") deep in 4140 steel. The hp is probably going to be okay, but I would be worried about the rigidity of the lathe and the tailstock travel. You're going to have to drill halfway and then flip it around and drill the other half if it's a through hole. Also what is the diameter of the 4140? Will you be able to chuck it in the lathe?
Anon is making 45acp barrels on the lathe again
>>2782390>>2782390nothere are literally calculators for this, but for anon's sake the hp needed is diameter times length (220mm convert to inch is 8.25 in) and then divide by pi. similar to the surface speeds/rpm calculation you can substitute pi for 4. your calculating the area of metal to be removed and converting to the area of hp needed inside the motor. 4140 vs 1018 vs o1 tool steel only affects rpm/feed rate.then 8.25/4 is a bit above 2hp needed.
>>2782390These machines work like a dremel zero torque but crazy fast rpm to remove material
>>2786626Shitting up /diy/ now?
>>2788955you can just abuse his trip if you want, pasteSieg #fuck niginto the name field
