End mills. 1. end mills cut rotationally in a horizontal, or lateral (side to side) direction whereas a drill bit only cuts straight down, vertically into the material. 2. endmills are available in a wide variety of lengths, diameters, flutes and types, and are chosen according to the material they are cutting and the surface finish required .
probably dumb question -- pocket won't allow use of ball end mill. i have a simple pocket that i want to rough with a .125in flat endmill and finish the edge with a .125 ball endmill to provide a fillet at the floor of the pocket (the fillet is modeled in the sw part).
ball-nose end mills. ball-nose end mills have a dome-shaped tip. these excel at high-detail contours like relief artwork or mold and die making, but have what is known as “scalloping.” since the tip of the end mill is round, having a perfectly flat surface is a challenging feat and will take many more passes than a simple fishtail to smooth .
Feb, 2019. evolved by addopting a th3 coating on 4-flute ball end mill for high hardened steel processing. on high-hardened steel processing, to achieve even longer tool life. highly efficient cutting with 4 flutes. special edge shape in tip area improves cutting performance. th3 coating provides long tool life even on hardened steels.
For longer tool life and a better finish in general purpose milling applications, these solid carbide end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills. their extreme hardness means they are brittle, so a highly rigid setup, such as a cnc machine, is necessary to prevent the end mill from breaking. they have a ball end for milling rounded .
posted janu. so i have never had to do this before in my career as a machinist. i have a part that needs a radius milled into the back side of it that runs the entire length of the part. the radius that needs to be machined is .475 . i have a 1/2 ball end mill in my machine, ready to start cutting, but i have no idea where to even .
as the title states. i do a ton of deep pocket milling in aluminum (usually 5-6 deep) most of the parts i can add a generous rad on the floor or in the case of 3d surfaces i can usually add a degree of draft to aid in getting down into the cavity. i am using solid carbide now, primarily swiftcarb .750 ramp mill, necked with 6 of reach.
3d pocket clearing - manual stepover for ball endmills so i have this 3d surface i want to machine out of mdf. my plan was to first use a 3d pocket operation for roughing and then a scallop toolpath for the finish - both with an 8mm ball endmill.
ball nose milling without a tilt angle. ball nose end mills are ideal for machining 3-dimensional contour shapes typically found in the mold and die industry, the manufacturing of turbine blades, and fulfilling general part radius requirements. to properly employ a ball nose end mill (with no tilt angle) and gain the optimal tool life and part finish, follow the 2-step process below (see figure 1).
special roughing end mills with serrations to break up chips are among the best tool types for removing material. however, they do produce a poor finish when compared to standard end mills. a final finish pass with a standard or finishing end mill will improve the surface finish. if space allows it, use a helical motion when plunging into a pocket.

well, here’s the x2 mini-mill making the pockets for the motor mount. click on the picture to play the video. don’t remember what speed it’s moving, but it’s taking a .02” depth of cut (doc) with a 1/2” 4-flute carbide end mill running at something over 000 rpms. it was pretty quiet since we had our belt drive installed.
if i mill a series of rings of decreasing diameter and increasing depth using a 1/2 ball end mill i should be able to get where i need to go. really if i had a table listing diameter and depth it would do the job. it needs to have no bumps where the step over / depth change occured. does anyone have time today, thanks.
the most common profile styles for end mills are square, corner radius, and ball. the square profile on an end mill has flutes with sharp corners that are squared off at 90 . a corner radius profile replaces the fragile sharp corner with a radius, adding strength and helping to prevent chipping while prolonging tool life.
