A Guide to CNC Router Tools & Bits
A CNC, also known as computer numerical control, router is a computer-controlled cutting machine used for cutting various materials, such as wood, plastic, metal, foam, and composites.
CNC router tools usually come in three different materials, that are: High Speed Steel (HSS), Solid Carbide and Diamond Tooling. Before starting the guide, let us learn the CNC router tool geometry.
Flutes: In CNC routing, flutes refer to the cutting edges or channels on a router bit. This is the part of the tool that augers out the cut material. The number of flutes on a cutter is important in determining the chip load.
Shank: The shank is the part of the tool that is held by the tool holder. It is the part of the tool that has no evidence of machining. The shank must be kept free of contamination, oxidation and scratching.
Cutting Length: Length of cut means the effective cutting depth of the tool or how deep the CNC router bit can cut into the material.
Cutting Diameter: This is the diameter or the width of the cut that the tool will produce.
Now, let us start CNC router bits and CNC router tools guide.
3D Burin CNC Tools
3D burin CNC tools are specialized router bits designed for creating intricate three-dimensional shapes and contours in various materials using a CNC machine. It has high concentricity, sharp edge. It is recommended to do precision 3D carving processing.
Edge CNC Router Bits
Edge CNC router bits are particular cutting tools designed for creating precise edges and profiles on work pieces using a CNC router machine. It is High density MDF, and wood is recommended to use edge CNC router bits.
Double Edge Straight Slot CNC Bits
Double edge straight slot CNC bits are cutting tools made to create accurate straight slots or grooves in work pieces using a CNC router machine. The multilayer board and plywood processing are recommend using double edge straight slot CNC bits.
Round Bottom CNC Tools
Round bottom CNC tools are cutting tools used in CNC machining processes. These tools have a rounded cutting edge at the tip, which allows them to create contoured or sculpted surfaces with smooth finishes. Precision small anaglyph processing is recommended using round bottom tools.
Double Blades Rowed Spiral Cutter
MDF cutting processing (advertising mould opening) is recommended to use double blades rowed spiral cutter. It has two high-capacity chip groove, double edge design, both of them contain a decent chip removal function, and can achieve a good balance tool. In processing high MDF, there is no black and no cap smoke. Moreover, it gives a lifelong service.
Single Blade Special Aluminum CNC Bits
Aluminum plate cutting process is recommended using single blade special aluminum CNC bits. Non-stick knife is used in the processing, as well as quick speed and high efficiency.
Single and Double Blade Up-Down Cutter
On the double sides burr-free cutting process, it is recommended to use single blade and double blade up-down cutter.
Single and Double Blade Straight Flute Sharp Cutter
In metal sculpture processing, use single and double blade straight flute a sharp knife.
Single Blade Spiral CNC Cutter
A Single Blade Spiral CNC Cutter is a type of cutting tool particularly used in woodworking applications. In acrylic cutting processing, you can use this cutter.
The characteristic of this cutter when processing is smokeless and odorless, fast speed, high efficiency, non-stick crumbs, and environmentally friendly. The special manufacturing process ensures that processing acrylic does not burst broken, fine grain or even no cutter grain. Lastly, the surface is bright, clean and level off.
Double three blade spiral CNC cutter
When you want to achieve frosted effect in machining surface, it is recommended to use double three blade spiral CNC cutter.
Diamond Graver
Diamond Graver refers to a cutting tool used in engraving, jewelry making, and precision machining. Acrylic mirror engraving processing is recommended to use diamond graver.
Multi-Stripes CNC Router Tools
A rough machining particieboard is recommended to use multi-stripes CNC tools.
Tungsten Steel CNC Router Tools
When it comes to the metal mold processing and milling cutter, it is recommended to use tungsten steel CNC cutter. The cutter has violet black hardened titanium plating surface.
Single Blade Helical Ball End Mill
For cork, density board, original wood, PVC, and acrylic large deep anaglyph processing is recommended to use single blade helical ball end mill.
Incised Cutter
When employing incised cutter processing techniques, the surface of the finished product will be smooth and without any rough edges or protrusions (burr). It also ensures that it does not develop any warping during the cutting or machining operation.
Finally, these are the detailed guide to CNC router bits. CNC tools play a crucial role in modern manufacturing and machining processes, offering unparalleled precision, efficiency, and versatility. Hope this guide will help you. Moreover, if you have any confusions or queries, feel free to ask us.
