CNC Machines for Acrylic Machining

CNC equipment for machining acrylic (PMMA)

Acrylic is a transparent plastic that requires precise control of cutting speed and cooling to prevent it from melting through friction during machining and losing its transparency in the machined area.

Characteristics and precautions when machining acrylic

Correct machining of acrylic depends on the spindle speed, the tool feed and a cutting geometry specific to plastic. A high-speed spindle, such as the one on our vertical series, makes it possible to work this material with good process control.

Vurcon machines recommended for PMMA and acrylics

• Spindle up to 10,000 rpm
• Automatic tool changer
• Numerical control to program plastic-specific feeds

Advantages of CNC machining for transparent plastics

Numerical control makes it possible to repeat exact cuts without relying on manual adjustment, which is especially relevant for acrylic, where uneven cutting pressure can mark or melt the material and affect its final finish.

Frequently asked questions about CNC acrylic machining

Why does acrylic melt when it is machined?

Because of the heat generated during cutting when the speed, feed or tool are not suitable for this material. Setting the parameters correctly prevents this problem.

Which machine do you recommend for acrylic parts with an optical finish?

Our vertical machining centers, adapting the tool and cutting parameters to the material. Check with our technical team for your specific application.

Can acrylic be polished after machining?

Polishing is a post-machining process that we do not carry out; consult your finishing or polishing supplier for this stage of the process.
