Learn More About CNC Router Bits from Cancam.ca
Whether you are thinking about trying CNC routing or you have officially started on it, chances are you are focused on the great projects you can do with the help of the exceptional precision of CNC machines. This is completely understandable. CNC or computer numerical control technology opens all sorts of brand new creative possibilities, from cutting out parts of the project to making signs. However, just like other kinds of routing, its magic is right at the tip of bits, or several bits, and you will want to fill your CNC toolbox with the right cutters from Cancam.ca.
Here is a quick rundown of the different router bits you can use:
End Mill Bits or Spiral Up-cut Bits
Such bits can cut straight yet feature spiral flutes which clear chips out and up from the recess that is being machined to leave a flat bottom. These are used for groove-making, cutouts, pocketing, and drilling so these are basically fundamental. A spiral up-cut bit with a diameter of ¼ inch is a great place to begin but you can also opt for 1/8 inch bit for tinier pockets, grooving or cutting items which require more drilling and detail cribbage board peg holes. As a general rule, take note that standard straight-cutting bits are not being used in the CNC machines.
Based on their name, such bits have cutting profiles in V shape. These are available with various included angles. This determines when you can use them best. A bit of 90 degrees can cut a bigger path and is more suitable for cutting shallower or larger details or letters. A bit with 60 degrees can allow smaller details and lettering and deeper cuts, crisper definition, and more contrasting shadows.
Fly-cutting or Surfacing Bits
Fly cutters feature cutters meant to plane the spoilboards or sacrificial tables on beds of CNC machines for them to be perfectly flat and to level workpieces before CNC machining.
The tapered ball-nose bits are important if you like to perform lithophanes or bas relief carving. It is best to get ball-nose bits of 1/16 inch, 1/8 inch, and ¼ inch. When used for clearing out material from a bigger area, these can leave tiny ridges in which cuts overlap, creating a scalloped visual effect perfect for several projects. If you don’t like scalloped ridges, you can eliminate them through decreasing the toolpath’s step-over. You can use a core-box bit to achieve a scalloped effect.
Other Types of Bits
When progressing with CNC routing, and working with various materials, there might be a need to widen your arsenal to include more bits meant for aluminum, plastics, as well as finer detail.
The Bottom Line
The bits utilized for CNC routing usually have two cutting edges or flutes. There are bits available with over two flutes, though. Just remember that as a general rule of thumb, bits with several fewer flutes can eliminate more material with every cut and need a slower feed rate.
