Milling cutters are mainly used for machining planes. Their characteristics are: high production efficiency; good rigidity, which can use a large feed; at the same time, multiple cutter teeth participate in cutting, and the work stability is good; Tooth grinding and replacement are easy and the tool life is long.
A face mill shell. The rectangular cutout area on the back side is the pocket that engages the lugs/tangs of the arbor. A shell mill is any of various milling cutters (typically a face mill or endmill) whose construction takes a modular form, with the shank (arbor) made separately from the body of the cutter, which is called a “shell” and attaches to the shank/arbor via any of several standardized joining methods.
This modular style of construction is appropriate for large milling cutters for about the same reason that large diesel engines use separate pieces for each cylinder and head whereas a smaller engine would use one integrated casting. Two reasons are that (1) for the maker it is more practical (and thus less expensive) to make the individual pieces as separate endeavors than to machine all their features in relation to each other while the whole unit is integrated (which would require a larger machine tool work envelope); and (2) the user can change some pieces while keeping other pieces the same (rather than changing the whole unit). One arbor can serve for various shells at different times. It is also possible that a crashed tool scraps only the shell rather than both the shell and arbor. To also avoid damage to the shell, many cutters, especially in larger diameters, also have another replaceable part called shim, which is mounted to the shell and the inserts are mounted on the shim. That way, in case of light damage, only the insert and maximum the shim needs replacement. The shell is safe. This would be like crashing a “regular” endmill and being able to reuse the shank rather than losing it along with the flutes.
