Question 1

Can acrylic be CNC machined?

Accepted Answer

Yes, acrylic (PMMA) can be successfully CNC machined. It's actually one of the most machinable plastics available. Our CNC machines are specifically optimized for acrylic processing, using the right cutting tools, speeds, and feeds to achieve excellent results with minimal tool marks and superior surface finish.

Question 2

Is PMMA machinable?

Accepted Answer

Absolutely! PMMA (Polymethyl methacrylate) is highly machinable and responds well to CNC machining processes. It can be milled, turned, drilled, and threaded with excellent precision. The material's stability and predictable behavior make it ideal for CNC machining, allowing us to achieve tight tolerances and complex geometries.

Question 3

What is the best CNC bit for cutting acrylic?

Accepted Answer

For cutting acrylic, we use specialized carbide end mills with polished flutes and sharp cutting edges. Single-flute or two-flute end mills work best as they provide efficient chip evacuation and reduce heat buildup. We also use diamond-coated tools for superior finish quality. The key is using sharp tools and proper cutting parameters to prevent melting and achieve clean cuts.

Question 4

What is the best way to machine acrylic?

Accepted Answer

The best way to machine acrylic involves several key factors: 1) Use sharp, polished cutting tools, 2) Maintain proper cutting speeds and feeds to prevent melting, 3) Use adequate coolant or compressed air for chip evacuation, 4) Secure the material properly to prevent vibration, 5) Use climb milling for better surface finish, and 6) Apply appropriate finishing techniques like flame polishing for optical clarity.
