CNC Acrylic Service | Professional Manufacturer of Optical Grade PMMA Precision Parts
Custom PMMA components for medical, optical, semiconductor, and automation sectors — 92% light transmittance, Ra 0.2-0.4µm, micron-level precision.
Why Choose Our CNC Acrylic Service?
- Professional Focus – long-term dedication to CNC acrylic service with 3/4/5-axis CNC machines, CNC lathes, turn-mill, and turret lathes.
- Optical-Grade Output – all finished parts keep 92% light transmittance, surface roughness Ra 0.2-0.4µm, and reliable micron-level precision, with a maximum size of 1200×800×420mm.
- One-Stop Service – material selection, process tuning, precision machining, polishing, and final inspection, fixing fogging, edge chipping, and internal stress.
- Flexible Orders – prototype, small-batch, and mass orders to match different production needs.
Equipment Strength for CNC Acrylic Service
- Complex Workpieces – curved surfaces, deep cavities, undercuts, special holes, and threads; one-time clamping avoids repeated positioning errors and tool marks.
- Proven Process – rough cutting followed by high-speed fine machining with diamond cutters keeps roughness at Ra 0.2-0.4µm and transmittance over 92%.
- Precision Assembly Fit – critical dimensions controlled within ±0.01mm, meeting GB/T 1804 Class F tolerance for premium optical devices.
Polishing Advantages of Our CNC Acrylic Service
- Multiple Techniques – hand finishing and wet sanding remove tool marks; cloth wheel polishing creates mirror finishes; oxy-hydrogen flame polishing for straight edges and soft curves; diamond mirror polishing for complex contours.
- Lens-Grade Finish – finest surface roughness reaches Ra 0.02µm, meeting optical lens standards.
- No Whitening – combined polishing techniques prevent whitening and halo, serving high-end optics, medical viewing windows, and laser equipment.
Quality Control for CNC Acrylic Service
- Premium Raw Materials – only brand-new high-transparency acrylic sheets, with pre-evaluated processing plans and on-site inspection.
- Full-Batch Checks – CMM, 2.5D measuring devices, roughness testers, stress detectors, and calipers with 100% testing of all key dimensions.
- Stable Compliance – micron-level detection on geometric tolerances, stably complying with GB/T 1804 Class F standards.

CNC Acrylic Service Advantages
We fix typical acrylic processing problems such as fogging, edge chipping, and internal stress, delivering crystal-clear finished parts for high-end optics, medical viewing windows, and laser equipment. Every acrylic part meets GB/T 1804 Class F tolerance requirements with light transmittance retention over 98%.
Will CNC machining cause obvious light transmittance loss on optical-grade acrylic?
A: Our custom processes and stress relief treatment prevent major loss. We maintain over 98% transmittance retention, well above the industry standard.
What’s the tolerance gap between 3/4-axis and 5-axis acrylic CNC machining?
A: Our 3-axis and 4-axis equipment maintains ±0.01mm tolerance for regular acrylic workpieces. Using 5-axis machining, we finish parts with higher precision and better surface quality for complex geometries.
Can you polish acrylic to lens-grade mirror finish, and which polishing methods do you use?
A: We can achieve a lens-quality mirror finish down to Ra 0.02µm. We select suitable polishing techniques based on edges, flat areas, and complex contours — hand finishing, cloth wheel, oxy-hydrogen flame, and diamond mirror polishing.
What is your maximum machining size and order flexibility for acrylic parts?
A: The largest acrylic workpiece we can process is 1200×800×420mm. We accept one-off prototype orders with a 7-day lead time, plus small-batch and mass production.
