Acryl ist in Platten und Rundmaterial erhältlich und sehr gut für CNC-Bearbeitung geeignet. Es kann jedoch auch mit anderen Fertigungstechnologien wie 3D-Druck und Spritzgießen verarbeitet werden.
Bei der Verarbeitung von transparenten Acrylteilen hat die CNC-Bearbeitung einen entscheidenden Vorteil: Sie ist die einzige Methode, um perfekte Transparenz zu erreichen. Außerdem kann sie sehr feine Details erzeugen. Generell ist die Bearbeitung von Acryl für hochwertige Teile in kleinen bis mittleren Stückzahlen vorzuziehen.
3D printing offers a few unique advantages over other processes, namely speed and geometrical flexibility. But the only process suitable for PMMA is FDM, and FDM 3D-Drucker are typically worse than SLA printers (compatible with various resins) for making transparent or translucent parts.
Das Spritzgießen ist das beste Herstellungsverfahren für große Stückzahlen von Acrylteilen, bietet jedoch weniger geometrische Freiheit als 3D-Druck und kann Teile nicht so detailliert oder transparent herstellen wie CNC-Bearbeitung. Es bietet gute Flexibilität bei der Farbgestaltung.

Acrylic machining with XTJ
Over the many years we have been involved in CNC machining, we have served many clients. And that diverse client base means that we have handled several complex procedures involving acrylic CNC machining.
Our staff has the skills that are needed to convert an acrylic panel into any desired shape and size. However, to ensure that our clients receive products that live up to their expectations, our professional engineers are happy to provide consultations. With this approach, we can be better placed to determine the needs of our clients and deliver CNC machined acrylic products with a guarantee of precision.
In addition to our skilled workforce, we have the right machines, cutting tools, and equipment to ensure that all of our work is of the highest quality.
Finally, all of the acrylic materials used at XTJ have passed our selection tests, guaranteeing optimal performance. Our engineers and technicians thoroughly investigate the structural quality of any material that we take for consideration, and this approach has enabled us to produce machined acrylic products that can withstand the strain of their end use, no matter their ultimate purpose.
Machining acrylic optical components with XTJ
Machined optical components such as lens assemblies and reflectors require a great deal of attention and precision. After years of research and dedication, XTJ has been able to drastically improve the surface of CNC milled parts, the result being a surface as transparent as the hand-polished alternative while maintaining cohesion with other parts.
When it comes to multi-components optical parts, the closer the finished components are to the design, the better the components will fit together. However, acrylic components typically require extensive manual polishing, which increases smoothness and optical clarity but reduces the accuracy of fine features and can result in ill-fitting components.
Our breakthroughs in this area are the culmination of hard work and extensive testing with many different machines.
Our engineers worked with various cutters and cooling systems, trialling several sets of parameters, to come up with the best solution. Our precisely calculated acrylic machining techniques mean it is no longer necessary hand-polish optical components and risk altering the parts in small but deeply significant ways.
