Modern mills perform functions such as:
When you set up a tool, you have a couple of choices in tool holders: chucks or collets. No matter how you hold your tool you need an R8 tool holder
to hold your tool holder!
Chucks use 3 or 4 “jaws” to hold the tool in place. You tighten and loosen the chuck by turning the shell of the chuck to increase or decrease the force of the jaws. Some of the chucks on hand-held tools can be tightened by hand. But on CNC tools and mills, a key is used. But using a chuck that needs a key means you must keep track on not only the chuck and but the chuck key as well. It's easy to waste time looking for a chuck or the chuck key.
Chucks are great if your job doesn't require precision. The chuck's design makes it very difficult to center a tool in the tool holder. Some chucks have implemented a “self centering” design that is supposed to equally apply the force to all the jaws as a means to center the tool. But it is still not exact.
Collets are another means of tool holding. Technically, a chuck is just a special type of collet. In machining lingo the term “collet” refers to a special type of R8 tool holder.
Collets go into the spindle where they are drawn into the mill and then tightened by
turning the drawbar with a spanner.
This hold the collet firmly in place and as a result the tool is truly centered and hold more securely than if a chuck were used. The result is much less run out, considerably less wobble, and far less ruined work. This allows you to work with far more precision. A casual hobbyist can get by with a chuck but professional machinists prefer a collet for the tool holder.
Because collets have a tapered shape, they require tapered holders.
R8 Tool Holder vs 5C Tool Holder
Well now that we’ve covered the types of tool holders, let’s look holding tool holders!
For simple tool changing, a collet tray is a great aid. When the job requires multiple tools, they can be set up in sequence to make the change quick and easy. Tool trays can also be a great way to carry tools from the tool room or crib to the work area.
R8 collets are internally threaded and fit in an R8 tool holder tray.
If your collets are externally threaded, then you have 5C collets and you use a 5C tray
. It would be wonderful if R8 and 5C trays were interchangeable, but they aren't. So you must have the right tray for the right tool holder.
