Custom PMMA CNC Machining Services
Weldo machines clear, colored, weather-resistant and medical-grade PMMA parts for optical, lighting, dental, electronic and display applications.
What Is PMMA CNC Machining?
PMMA CNC machining is a subtractive process that cuts acrylic sheet, block or rod with programmed CNC equipment—not a molding process. It supports precise features without dedicated tooling.
Optical Clarity
Clear PMMA grades can reach up to 92% visible-light transmission, depending on product and finish.
Light and Weatherable
Low density and good weather resistance suit lenses, covers, signs and lighting parts.
Machining Control
Sharp tools, controlled heat and low-stress workholding help prevent cracking and distortion.
*Transparency, UV performance and sterilization compatibility vary by PMMA grade and must be confirmed for the application.
Common PMMA Material Options
Select PMMA according to transparency, color, surface effect, outdoor exposure and medical or dental requirements.
Durchsichtiges PMMA
High clarity and polishability for lenses, light guides, covers and display components.
Farbiges transparentes PMMA
Controlled tint with retained light transmission for signs, light boxes and electronics.
Pearlescent or Embossed
Visual texture for decorative panels, custom lighting and branded parts.
Wetterbeständiges PMMA
Grades formulated to reduce UV-related yellowing and property loss outdoors.
Medical or Dental PMMA
Application-specific grades for dental restorations, diagnostics and medical components.
PMMA CNC Machining Parts and Applications
CNC machining produces clear, colored and dental PMMA components from prototypes through low-volume production without mold tooling.
Surface Finishes for PMMA Parts
Finishing can improve clarity, texture, appearance and edge safety. The method should match the PMMA grade, geometry and optical requirement.
Unbearbeitet
Visible tool marks remain; suitable for functional or hidden features where optical clarity is not required.
Mechanical or Diamond Polish
Reduces tool marks and improves transparency; diamond tooling supports higher optical quality.
Flammpolieren
Produces glossy edges quickly, but heat and residual stress must be controlled to prevent distortion or crazing.
Texture, Coating and Edge Work
Sandblasting, painting or hard coating modifies appearance. Anfasen und filleting improve handling and fit.

Häufig gestellte Fragen
Concise answers covering cracking, cost, process choice, optical finishing and medical-grade selection.
How can cracking or chipping be reduced?
Use sharp carbide or diamond tools, control heat and vibration, avoid excessive clamping pressure and select cooling compatible with the PMMA grade.
What affects PMMA CNC machining cost?
Material thickness, part size, geometry, tolerance, quantity, setup count, polishing, annealing, coating and inspection requirements affect the quote.
When is CNC machining preferable to molding or 3D printing?
CNC is well suited to precise prototypes and low-volume parts without mold tooling. Injection molding fits higher volumes; 3D printing favors fast form checks.
How is optical clarity improved after machining?
Stable cutting reduces stress and tool marks. Mechanical, diamond or controlled flame polishing can improve clarity according to geometry and finish targets.
Is PMMA suitable for medical or dental parts?
Validated medical or dental grades may be suitable. Confirm certification, biocompatibility and sterilization compatibility for the specific device and region.
