A diagram of a solid single-form thread cutting tool A solid multiple-form thread milling cutter. Whereas a hob engages the work much as a mating gear would and cuts the blank progressively until it reaches final shapea thread milling cutter operates much like ball nose cutter endmill, traveling around the work in a helical interpolation.
Face mill[ edit ] A face mill is a cutter designed for facing as opposed to e. The cutting edges of face mills are always located along its sides.
As such it must always cut in a horizontal direction at a given depth coming from outside the stock. Multiple teeth distribute the chip load, and since the teeth are normally disposable carbide insertsthis combination allows for very large and efficient face milling.
Fly cutter[ edit ] A fly cutter is composed of a body into which one or two tool bits are inserted. As the entire unit rotates, the tool bits take broad, shallow facing cuts. Fly cutters are analogous to face mills in that their purpose is face milling and their individual cutters are replaceable.
Face mills are more ideal in various respects e. Most fly cutters simply have a cylindrical center body that holds one tool bit. It is usually a standard left-hand turning tool that is held at an angle of 30 to 60 degrees.
Fly cutters with two tool bits have no "official" name but are often called double fly cutters, double-end fly cutters, or fly bars.
The latter name reflects that they often take the form of a bar of steel with a tool bit fastened on each end. Often these bits ball nose cutter be mounted at right angles to the bar's main axis, and the cutting geometry is supplied by using a standard right-hand turning tool.
Ball Nose Cutter
Fly bars are rarely sold commercially; they are usually made by the user. Fly bars are perhaps ball nose cutter bit more dangerous to use than endmills ball nose cutter regular fly cutters because of their larger swing. As one machinist put it, running a fly bar is like "running a lawn mower without the deck",  that is, the exposed swinging cutter is a rather large opportunity to take in nearby hand tools, rags, fingers, and so on.
However, given that a machinist can never be careless with impunity around rotating cutters or workpieces, this just means using the same care as always except with slightly higher stakes.
Woodruff key cutters and keys Ball nose cutter cutters are used to cut the keyway for a woodruff key. Hollow mill[ edit ] Hollow milling cutters, more often called simply hollow mills, are essentially "inside-out endmills".
They are shaped like a piece of pipe but with thicker wallswith their cutting edges on the inside surface. They are used on turret lathes and screw machines as an alternative to turning with a box toolor on milling machines or drill presses to finish a cylindrical boss such as ball nose cutter trunnion.
Ball Nose End Mill
Dovetail cutter[ edit ] A dovetail cutter is an endmill whose form leaves behind a dovetail slot, such as often forms the ways of a machine tool. Modular principle[ edit ] A face mill shell. 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 ball nose cutter than changing the whole unit.
One arbor at a hypothetical price of USD can serve for various shells at different times.
Ball nose cutters
Thus 5 different milling cutters may require only USD worth of arbor cost, rather than USD, ball nose cutter long as the workflow of the shop does not require them all to be set up simultaneously.
It is also possible that a crashed tool scraps only the shell rather than both the shell and arbor.
This would be like crashing a "regular" endmill and being able to reuse the shank rather than losing it along with the flutes. Most shell mills made today use indexable inserts for the cutting edges—thus shank, body, and cutting edges are all modular components.
