アクリルはシートや丸棒として入手でき、CNC加工に非常に適しています。ただし、3Dプリントや射出成形などの他の製造技術も利用可能です。
透明なアクリル部品を扱う場合、CNC加工の最大の利点は、完全な透明度を実現できることです。また、非常に細かいディテールも作り出せます。一般的に、アクリルの加工は少量から中量の高品質部品に適しています。
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プリンター are typically worse than SLA printers (compatible with various resins) for making transparent or translucent parts.
射出成形は、大量のアクリル部品を製造する最良の方法ですが、3Dプリントほどジオメトリの自由度は高くなく、CNC加工ほど詳細や透明度を実現できません。色彩の柔軟性も良好です。
Machining Acrylic vs other clear plastics
Machined acrylic is desirable for its transparency, but Polycarbonate and ABS are potential alternatives to the material with their own unique advantages.
PMMA
Very high level of clarity
Easy to polish
Brittle compared to PC
PC
High impact resistance
High temp resistance
Less clear than PMMA
More expensive than PMMA
ABS
High impact resistance
Low cost
Resistant to stress cracks
Harder to color than PC
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.
XTJは、試作から量産までの6061アルミニウムの加工におけるワンストップ製造ソリューションを提供する大手OEMメーカーです。私たちはISO 9001認証の品質管理システムを誇りに思い、すべての顧客関係に価値を創造することを決意しています。それは、協力、革新、プロセス改善、そして卓越した職人技を通じて実現しています。用途：自動車産業、自転車およびオートバイ、ドア・窓・家具、家庭用電化製品、ガスメーター、電動工具、LED照明、医療機器部品など。
