Videos on how to machine a jewelry wax model.

Creating Jewelry wax models is an important application for DeskProto: many jewelers worldwide have found that CNC machining makes it affordable to build your wax-models in-house, and that DeskProto is an excellent tool to do this.
The most important product in jewelry design are rings, so the jewelry tutorial videos on this page show how to create a ring model: These videos do not apply to DeskProto Entry Edition and Expert Edition: rotation axis machining is not possible in these editions.

1. Sample ring STL file

The ring geometry shown below has been created by Chris Botha. It is a great example of the complexity that can be achieved using CAD/CAM tools. It is used in the first video, and can be downloaded free of charge.

This beautiful ring model (STL file) has been created by Chris Botha.

Chris has allowed you to download and use this model for DeskProto training purposes. The file is an 8.5 MB file, containing the simple test ring STL used to create a template project, the template project, the ring STL file, the pyramid STL and the 2D DXF curve.
He (Chris Botha) also offers a training DVD for basic jewelry design in Rhino:

2. Three-Sided Ring tutorial video

Creating toolpaths to machine a wax ring: from two sides (autoflip) and after that a rotary pass   (30.5 min)

The Three-Sided Ring video teaches you how to create toolpaths for creating a wax model of a ring. Three sided: the ring first is milled while lying flat, from two sides. After that the third "side" is a rotary pass, where the model rotates during machining.
An easy way to prepare such toolpaths is by using a Template project: this is a project that already contains all settings, however in which no geometry is present yet. The video clearly explains how to create and use such template project.
A note about this video: right-clicking the mouse in the tree is not needed. You can double-click any line in the tree to edit it's parameters.

This instruction video has been created by He (Chris Botha) also offers a training DVD for basic jewelry design in Rhino.

3. 123 Wax Ring promotional video

Promotion video for the 123WaxRing system   (4.5 min)

The 123WaxRing video is a promotion movie for an optional extra tool for DeskProto: the 123WaxRing system.
This combination of an extra wizard in DeskProto and a fixture for on the machine is especially meant for jewelers, to make creating wax ring models very easy. All your wax models will be created:
  • using pre-shaped wax disks,
  • using the same fixture,
  • using the same cutter,
  • using the same zero point.

4. JWX-30 wizard video

Tutorial video for the DeskProto JWX30 wizard   (13 min)

The JWX30 video shows DeskProto with the Roland JWX-30 machine. This wax milling machine has a unique feature: an automatic calibration process to accurately set the WorkPiece zero point (which otherwise proves to be difficult for many jewelers).

In DeskProto a special wizard is present for this machine, which makes creating toolpaths very easy. Advantages of using DeskProto instead of the standard Roland SRP Player software are that DeskProto calculates much faster, and also that that toolpaths are much more efficient (shorter milling time).
The video shows the calibration, calculating the toolpaths, milling the wax model and some conclusions.
Also see the Seal Ring gallery project.

5. Magic-7 Basic Ring video

Tutorial video about machining a simple wax ring on the Red Technology Magic-7 milling machine   (11 min)

The Magic-7 video shows DeskProto with the RedT Magic-7 machine. This machine is aimed at jewelers, for engraving rings, pencils, hangers, etc. We will show that it is also very suitable to create jewelry wax models.

In DeskProto we will use the Custom wizard called 4 axis wax ring, to easily create the toolpaths for a ring design. After loading a standard wax tube on the machine (and setting the zero point) the NC file from DeskProto can be sent to the machine.
Also see the DeskProto Tips and Tricks page about the Magic-7 machine.

6. Results showcase for the sample ring

Machining side 2 of the ring, in purple wax
Detail of the wax model, after completing side 2
Side 2 is almost finished, detail shows the pyramid

The first results (four pictures shown) have been made by Chris Botha (
He uses a MiniTech machine, with a rotary axis and a four-jaw chuck. Side 1 and 2 have been machined by simply clamping the waxblock in this chuck: see the first picture.

Before starting rotation axis machining the tip of the cutter is aligned with the pyramid

Using the tip of the pyramid to align the tip or the cutter, and the final result

For the 3rd pass (the rotary pass) the wax model has been clamped using the "4th Option Fixture", made and sold by Brant Emery in the USA, email wax-guy[at]

Email us a photo of the ring that you created so we can add that to the list of results !
(in case you want with a link to your website).
It will be interesting to see which machines are used, which cutters, and also which fixtures for three sided ring machining.
