For Your Safety

  1. The methods illustrated here are only intended for use with a CNC milling machine.
  2. Make certain that the workpiece is secured and that all components of the fixture are securely fastened to the table.
  3. Use a guard, eye and hearing protection at all times.

Watch Part 1 of 2 Here.

Watch master mechanic John from NYC CNC as he 3D carves an amazingly small Microorganism Art Design from a 2" wide x 5" heigh piece of brass round using Amana Tool® industrial CNC router bits.

We provided John the artwork in .STL file format of a Microorganism magnified with a microscope. This file was created by Pierre-Luc Arseneau from CNCcraze.com and has over 600,000 facets!

Step 1.
Amana's Solid Carbide Spiral 'O' Flute 1/4" Dia. Aluminum Cutting CNC Router Bit #51402cuts the top 1/4" of the brass round to a 1" square.

Step 2.
Amana's Insert Solid Carbide Face Milling Aluminum End Mill 2-31/64" Dia. CNC Router Bit #RC-3400 Face Mills the top of the brass for a even surface.

Step 3. (Roughing Pass)
Solid Carbide ZrN Coated Spiral 2D/3D Carving Tapered Ball Nose 3/16" Dia. CNC Router Bit #46298 for a roughing pass.

Step 4. (Finishing Pass)
Solid Carbide ZrN Coated Spiral 2D/3D Carving Tapered Ball Nose 3/16" Dia. CNC Router Bit #46298 for a finishing pass.

Step 5.
Solid Carbide ZrN Coated Spiral 2D/3D Carving Tapered Ball Nose 1/16" Dia. CNC Router Bit #46282 carves out the fine details.

Step 6.
Spiral 2D/3D Carving Tapered Ball Nose 1mm Dia. CNC Router Bit #46471 carves out the extremely fine details.

VIDEO TRANSCRIPTION:

To start out we'll use tool number 51402 from ToolsToday. It's a single flute quarter inch end mill. We'll use that to just rough out the stock around the piece of brass we've got. And then we'll use RC3400, it's a four flute about two and half inch face mill to give us a really nice finish over the top of the part. And then we're going to come in three-sixteenth inch ball end mill today from ToolsToday.

That same one-sixteenth inch end mill and god, it's just beautiful from ToolsToday. One millimeter or about 40,000 ball end mill from ToolsToday, part number 46471, all this info is in the video description below. Well look at that. Let's zoom in with the 100 millimeter macro lens and see how see looks. Isn't that awesome folks? Look at that detail on that.

Half [inaudible 00:03:14]. I don't even know, couple hundred thousand lines of code I think. No problem at all. About a two hour eight minute sprung time, so not all that bad, we didn't break any tools, which I was excited about as well and I think that's a really cool...
