Hello all.
I need a quote for a piece of 6061 aluminum with 20 slotts milled into it.
let me describe the part. 5"x7"x3" lets call 3" the height. 5" the depth and 7" the length. i need 20 .125" slots milled along the length (7inch long slots) spaced .125" apart. these slots have to be 2" deep. their is one spot inn the very center of the part which cannot have slots. this needs to be a portion of the billet that is 1.250"x1.250" square.
so if you use the bottom left corner of the billet as the refrence point, the center point of the 1.250"x1.250" space with no slots would be 3.5 inches in from the left and 2.5 inches in from the bottom.
one other thing- the bottoms of the slots must not have 90degree edges. a ball nose endmill could be used or just radiusing the corners of the end mill or slotting cutter will suffice. my requirement here is that their is a minimum of a .010" radius at the bottom of the slots. obviously that would be on both sides. a full .125" radius would be fine too as that could be done with just a .125" ball nose endmill. 90degree corners must be avoided due to stress generated by vibration on this engine. i would like to avoid a cracking of the head at the bottom of the slots- hence the need for a radius.
I only need one of these parts made.
having this part made by the end of april is mandatory.
please quote price with the cost of the 6061 aluminum block included.
please quote asap as i need to have this project started fast.

it may help to know that this will eventually be an aircooled cyllinder head.
cyllinder stud holes, combustion chamber and plug threads i can do myself on my equipment. i dont have the capability do do 2" deep slotting.
