Milling With a CNC Lathe – Gears & Gizmos

A post describing a plastic milling project I did

I got the idea from watching some videos of other people making things with their CNC lathe and this was my first try at doing it

This is a plastic gear for a computer fan. I used a piece of scrap acrylic as a template and then cut it out with my Dremel. After that, I sanded the edges so they wouldn't be sharp and would fit together well. Then I used a 3D printer to print out some small gears to put in place. The gears were made out of wood because they broke easily when trying to insert them into their holes in the gear shaft. After that I drilled holes through both pieces of wood where they needed to be drilled through, used a file to smooth out any rough edges on the gears, then glued them together with epoxy resin glue and clamped them until they cured overnight (about 12 hours).

CNC Plastic Machining

CNC Machining Plastic Parts are widely used in all industries fields and most products around us in the world. And many plastic materials are suitable for machining processes.

Therefore, CNC machining plastic parts are important production way to make out plastic products.

Different plastics have different properties, with their low cost and multi-selecting reason, so CNC machining plastic parts are flexibly choose plastic materials for various functional products.

Different processing use different materials for its functional purpose. Normally we use ABS, PS, PC, Nylon, PEEK, PA, POM, etc. For plastic parts by CNC turning, milling, drilling; And apply finishing treatment on surface such as painting, powder coating, etc.

Benefits of CNC Plastic Machining

1/ Plastic materials have many series with different properties for different choice

2/ Plastic materials is soft, shape-keeping, and easy-cutting for CNC machining processes

3/ CNC machining plastic parts are light-weight for product using

4/ CNC machining plastic parts are non-conductive of electricity, supporting many non-conductive parts

5/ CNC machining plastic parts are flexible to change the shape, benefiting the prototyping time and cost

6/ Plastic parts material supporting recycle collecting, material renewal benefits the burden of world
