5 Axis CNC

At the heart of the Monolith Aeroworks prototyping toolbox, there lives a 20 ton  5 Axis CNC, Fanuc controlled, Japanese built, gantry milling robot affectionately named Ms. Avocado.  Don’t let her dainty name fool you. Ms. Avocado is big, strong, and she will accurately convert your material of choice into the next world changing design in no time flat.  She can repeatedly hold tolerances of less than .005 of an inch, and can be configured to fixture a large variety of materials, part sizes and shapes.

Materials typically cut by Ms. Avocado include:
Polyurethane tooling foams of all densities
Epoxy board
Composite laminate
Composite sandwich panel
Compo tool
Foam core
Honeycomb core

Ms. Avocado is equipped with a vacuum fixture table that allows for quick setup times, and  correctly supports the lightest weight materials during machining.

Contact us today to discuss how we can put Ms. Avocado to work for you!

Design and Analysis

Monolith Aeroworks uses the Solidworks family of engineering software to design, analyze, machine, and tool all of our projects.  This loyalty to a single software package streamlines the engineering work flow  and  prevents costly rework caused by multiple software translations and users.

The Monolith Aeroworks team is able to offer the greatest benefit when we are involved in the early design phases of a project.  With our expertise involved at the onset of design we can provide your project with the best value, highest quality, and quickest build times possible.

How soon would you like to have your parts delivered?
