PMMA / Acrylic Machining
PMMA / Acrylic CNC Machining Services
Precision machined acrylic components for semiconductor, laboratory, medical, microfluidic, and scientific applications.
Why PMMA
Why PMMA Is Used for Precision Plastic Components
PMMA combines transparency, machinability, and stable performance for demanding technical parts.
PMMA, commonly known as acrylic, is selected when a component requires visibility, clean appearance, lightweight construction, and precise machining. It is widely used for transparent manifolds, microfluidic parts, optical elements, laboratory fixtures, and custom acrylic components.
High Transparency
Suitable for parts where visual inspection, light transmission, or internal fluid paths must remain visible.
Optical Clarity
Machined and polished acrylic can support optical, display, and laboratory observation requirements.
Lightweight
Acrylic offers a lower-weight alternative to glass in fixtures, covers, manifolds, and test assemblies.
Excellent Machinability
PMMA can be milled, drilled, threaded, polished, and machined into complex transparent components.
Chemical Resistance
Useful in selected laboratory and fluid-handling environments depending on the chemicals involved.
Dimensional Control
Proper tooling, fixturing, and process control help maintain critical features and clean edges.

CNC Acrylic Machining Capabilities
Machining methods adapted to PMMA material behavior and surface requirements.
Acrylic machining requires controlled cutting parameters, appropriate tools, stable workholding, and careful finishing to avoid cracking, chipping, melting, and poor transparency.
Milling
Profiles, slots, pockets, channels, and complex machined surfaces.
Turning
Round parts, sleeves, transparent bushings, and cylindrical features.
Drilling
Clean holes, ports, and precision opening features.
Threading
Internal and external threads for assembly and fluidic components.
Polishing
Edge and surface finishing for improved transparency and appearance.
Micro Features
Small channels, pockets, holes, and fluidic details.
Surface Finish
Surface Finish & Optical Quality
The final appearance of acrylic depends on machining strategy and finishing requirements.
For acrylic parts, surface finish may affect clarity, sealing, inspection, flow visibility, and product appearance. Micrylix can review finish expectations during RFQ to match the part function.
Machined Finish
Suitable for functional parts where tool marks are acceptable or hidden in assembly.
Polished Finish
Improved edge clarity and visual appearance for exposed transparent surfaces.
Optical-Grade Finish
Reviewed case by case for applications with stricter transparency or optical requirements.
Transparency Considerations
Geometry, material grade, machining marks, and polishing scope all influence clarity.

FAQ
PMMA / Acrylic Machining FAQ
What is PMMA?
PMMA is polymethyl methacrylate, commonly known as acrylic. It is a transparent engineering plastic used for optical, laboratory, display, and fluidic components.
What tolerances can be achieved?
Tolerance depends on part size, geometry, material condition, and feature requirements. Critical tolerances should be reviewed from the drawing during RFQ.
Can acrylic parts be polished?
Yes. Acrylic parts can be machined and then polished when improved transparency or visual appearance is required.
Do you support prototypes?
Yes. Micrylix supports prototype quantities, small batches, and repeat production for custom acrylic components.
Can you manufacture from STEP files?
Yes. STEP files are accepted. For quotation, please also provide drawings when tolerances, threads, surface finish, or critical features need to be controlled.
