Acrylic, also known as plexiglass, is widely used in the industry. Acrylic products are also very common in our lives. How do acrylic sheets become the various finished products we see in our lives?
What Is Acrylic (PMMA)
Acrylic, also known as Polymethyl Methacrylate (PMMA), is a thermoplastic material with remarkable attributes. This versatile plastic retains its fundamental characteristics even when melted and reshaped. Unlike some other clear plastics, acrylic does not discolor after prolonged exposure to sunlight. It stands as an excellent alternative to glass in various applications, finding extensive use in industries like automotive and test and measurement.
How to process acrylic and what processing techniques are available:
Laser cutting is a non-contact cutting method. Laser cut acrylic can cut acrylic into various shapes at will. It can cut words, patterns, furniture, etc. Laser cutting machines can be used to make various logos out of acrylic, including complex patterns, etc., which play a very important role and position in the advertising industry. Acrylic cutting is the most common process in acrylic applications of laser cutting machines.
Acrylic can also be directly drilled. Compared with glass, acrylic has very good machining characteristics. Using a laser cutting machine to drill holes has very high assembly accuracy. You only need to make pictures in the computer to pass the computer Drilled holes in the acrylic.
Acrylic itself has high transparency. After polishing acrylic, it has the same high transparency as crystal. The polished acrylic is very smooth and highly appreciable, and can be used for a variety of handicrafts.
4. Hot bending:
Acrylic material will melt at 70°-100°, and this heat can be used to modify the shape of acrylic, including irregular shapes. Acrylic hot bending can be achieved in different ways. Many acrylic sheets can be placed on a set of hot bending machines and shaping molds at the same time for hot bending and shaping. Most of the hot bending is only through single line or parallel line hot bending. The angle of hot bending can be determined according to needs to control the angle.
Bonding is a very labor-intensive process. When bonding, you must pay special attention to the position and accuracy of the process, otherwise there will be a lot of defective products that will affect sales.
Assembly is the process of combining various processed acrylics to complete a product. This is also the last step of a complete set of handicrafts. It will also be revealed in this last step to check whether the previous craftsmanship is qualified.
CNC PMMA Machining Techniques
Acrylic lends itself nicely to a variety of acrylic cnc machining techniques. The technique used is often determined by the requirements provided by the customer. Depending on the intended product design, one or more of the following processes may be used in the manufacture of acrylic.
CNC Acrylic Milling
This method of CNC machining acrylic provides excellent chip control and requires the removal of acrylic material. The acrylic sheet or other workpiece is fed through the CNC machine and then cut using the appropriate cutting tool. It moves in the same direction as the cutting instrument while it does this. This method shines when used for the milling of intricate geometries. CNC machining of acrylic is best accomplished using cutting tools that feature edge rake angles and rotating multi-points. The acrylic milling machine shop can do a variety of cuts, from shallow to deep to peripheral, with the help of this cutting tool.
CNC Acrylic Turning
This method of producing acrylic products requires cutting away at a rotating piece of acrylic. In contrast to CNC milling acrylic, the cutting tool utilized here only has one axis of rotation. During this method of CNC machining acrylic, the machine passes the cutting tool in a straight line over the surface of the acrylic workpiece. It works its way around the item, cutting away excess material until the desired form is achieved. Thread cutting, boring, grooving, and facing are only some of the CNC acrylic turning’s machining capabilities.

To sum up, the remarkable adaptability and safety of CNC acrylic machining make it stand out in a variety of applications. PMMA processing is made efficient by CNC systems because of their ease of manufacture. This guide has provided insightful advice for the best outcomes while illuminating the advantages and machining procedures. Unleash your creativity by exploring the countless possibilities that come with painting with acrylic.
Machined optical components such as lens assemblies and reflectors require a great deal of attention and precision. After years of research and dedication, BE-CU 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.Be-Cu.com,china rapid prototyping manufacturer provides the highest standard of CNC machining service for all your needs.
