Machinable wax is an extremely hard synthetic (microcrystalline) wax that exhibits excellent machining characteristics. Since it is harder and has a higher melting temperature than most other waxes, machinable wax can be machined, cut, or shaped using standard metalworking or woodworking equipment. High quality surface detail and dimensional accuracy are possible. Machinable Wax is ideal for verifying CNC machining programs. It can also be used to produce accurate molds and prototypes. Machinable Wax is available in both blocks and cylinders. We stock the most commonly requested sizes and can usually provide alternate sizes on request.

Machinable wax offers distinct advantages over other prototyping materials for some applications. The product is environmentally friendly and the shavings produce no harmful dust, odor or irritants. The material is self-lubricating and easy on tooling.

Machinable wax can be recycled. The shavings and unused pieces of material can be re-melted and formed back into useable material. This attribute can substantially reduce the cost of using machinable wax over other materials. We've put together a short video that will give you a few idea and show you what to expect if you want to try recycling yourself. LINK TO RECYCLING VIDEO >>

The self-releasing properties of machinable wax make it an ideal choice to use as a master model. Epoxies and polyurethanes can be poured directly onto the wax surface without the need for sealers or release agents. You can also bond machinable wax pieces together by using spray on adhesives such as the #90 Hi-Strength Spray Adhesive from the 3M company.

Suggested Machining Information for Machinable Wax:
Some small CNC machines can't reach the RPM or feed rate shown below. That's okay. Using a small cutter under 1/2" diameter, you can get great results with spindle speeds as low as 1000 RPM and feed rates as low as 10 inches per minute.

(This example was obtained using 1/2" end mill. If you slow down the feed rate then you can reduce the RPM):

• Roughing: Spindle speed 3,000 rpm at ~ 100 inches per minute
• Finishing: Spindle speed 8,000 to 10,000 rpm at ~ 40-100 inches per minute

Property Specifications:

• Hardness: 50-55 (Shore "D" Scale)
  
• Specific Gravity: 0.92
  
• Flash Point: 575 degrees F
  
• Softening Point: 226 degrees F
  
• Volumetric Shrinkage (for recycling, from melting point to room temp): 7%
  
• Coloring: blue dye, permanent, oil base
• Ash content for lost wax casting applications is low (.0054%)
