The following part was chosen for the test, and we began manufacturing, simultaneously recording all the milling steps. First, it was necessary to decide on the processing technology. In fact, the technology for manufacturing such parts is quite simple, you first need to do roughing, then finishing for one side, then turn it over, and do the same for the reverse.
To automatically turn over, a rotary axis would be required, and supports would have to be placed on the model to hold the model when turning over. And if the presence of supports in this case would not be a problem (they can be easily removed manually), then it was decided to abandon the rotary axis in order to meet the budget allocated for the purchase of equipment. So, it was decided to make the test part on a Roland MDX-540 with manual rotation.
ABS plastic itself is quite even and smooth, so it was decided to fix the workpiece on the table in the most in a simple way- using double-sided tape.
Since the body part is not very large, an end mill with a diameter of 6 mm ( The MDX-540 can accommodate cutters with a shank up to 10mm). After the rough layering was completed, the end mill was replaced with a 3mm ball end mill ( spherical was chosen to provide high quality surfaces, and the diameter is 3 mm to ensure the required rounding radii in the corners).
Before removing the part from the machine, it was necessary to make small modifications to the elements that turned out to be too small for a cutter with a diameter of 3 mm. Using an end mill with a diameter of 3 mm, we made grooves on the inclined part and mounting holes. 
The part can now be removed from the machine. In order to position the part when turning over, you can use a temporary jig. To make it, we simply fix a piece of plastic on the table and mill out a recess along the contour of the part. 
Then you can simply insert a part into it, the coordinate systems of the machine and the part will coincide, and it will simply be held in place by friction. This fastening method is great if you need to mill up to 5-10 products, then the plastic jig will break and will have to be redone. But this fastening method is also good for large series; you just need to add a small screw fastening to it ( for example, as was done in the test with bottle caps).
The processing of the front side generally repeated the processing of the internal side; first, we did a layer-by-layer rough processing with an end mill with a diameter of 6 mm, then we changed the cutter to a spherical cutter with a diameter of 3 mm and did the finishing processing. And before removing the finished product from the machine, we used a 1.5mm end mill to make a small modification to the plane on which the stiffeners and mounting holes are located. This was necessary to ensure a rounding radius in the corners of the ribs, as well as to remove a small rounding radius between the mounting plane and the side walls. Refinement is required because, due to the geometry of the cutters, a minimal unprocessed area remains, only a few tenths of a millimeter (roughing with an end mill leaves a small allowance, and finishing
Milling ABC plastic has the following advantages over laser cutting:
- adjustable cutting depth
- no color distortion at the cutting point
- creation of multi-level volumetric parts (3D cutting)
- speed adjustment (which eliminates the release of harmful substances).
MILLING MATERIALS
Our company carries out milling of the following types of plastic:
- polyvinyl chloride;
- polystyrene;
- polypropylene;
- polycarbonate;
- acrylic, etc.
FEATURES OF ABS PLASTIC MILLING
Milling plastic to order in St. Petersburg has its own characteristics. According to their physical and chemical parameters, plastic is divided into two types:
- thermoplastics;
- thermosets.
The first type of polymers has low temperature melting, which greatly affects the speed of milling work on plastic. Exceeding the processing speed leads to loss of the original shape of the part. The second type of polymers has high strength, which makes it necessary to use carbide tools for work (for example, finger cutters for plastic).
WHERE TO ORDER PLASTIC MILLING?
Volumetric milling of ABC plastic at the Sistema Machining Center company is carried out to order in St. Petersburg, Moscow and other cities of Russia. This process makes it possible to obtain precise workpieces with smooth, well-processed edges, without traces of melting and thermal deformation (appearing due to overheating of the polymer part).
Our company has equipment for polymer milling, which allows us to create molds for polymer casting and vacuum molding. We produce high-precision cutting of ABS PLASTIC, produce master models (prototypes, prototypes), apply flat and three-dimensional drawings to the surface of the plastic (we provide services for 3D milling of plastic to order).
Plastic is a common material in demand, low in cost and easy to process. It is also convenient to use and has positive technical characteristics. Products made from plastic are now present almost everywhere, in many areas of human activity. These are advertising products, window profiles, interior elements, household items, etc. Plastic is especially actively used in the industry involved in the production of advertising products. To produce outdoor advertising items you need plastic milling, which is performed both manually and using special equipment.
Of course, to quickly produce high-quality advertising objects made of plastic, it is preferable to use modern milling machines. A service like plastic milling in Moscow, many companies offer, but not all of them work responsibly, and the prices are often inflated. Therefore, if you need high-quality or abs milling plastic, then it is advisable to contact a reliable company with a good reputation. This is our company, Sign System, which provides plastic milling services on high level at affordable, reasonable prices.
Application of modern CNC milling for cutting plastic materials makes it possible to give workpieces the required configuration, apply inscriptions, images, drill holes, form protrusions, creating relief. Which plastic for CNC milling better fit? On equipment of this type It is possible to process any type of plastic, as it has a number of advantages and disadvantages. There are a number of plastic materials, such as polyamide or polypropylene, that are more difficult to process. This requires precise, correct selection and installation of milling equipment settings: cutter operating speed, type of milling, etc. Our specialists are able to cope even with complex tasks, because they have work experience, the necessary skills and abilities. We process with high quality different kinds plastic, and our price for services is lower than in many other companies.
Another quite popular service is milling on plastic facades, our company also provides it. The modern milling machines we have give us the opportunity to create three-dimensional images, apply ledges and grooves, and then mount profileless structures. There is no soot left on the parts, there are no traces of melting, the parts do not deform and do not change color on the cut edges. It is also possible laser milling of plastic, in some cases, but for plastic it is not used very often. We are not limited to milling plastic to create only advertising objects; we process plastic to create interior parts, household items, etc.
If you are interested in the most profitable price of plastic milling in our company it is inexpensive, and orders are fulfilled promptly, in the shortest possible time. Processing plastic using CNC-equipped equipment has a number of advantages and disadvantages. Firstly, this is the almost perfect accuracy with which parts are manufactured. Secondly, it is a higher processing speed, which makes it possible to produce a large number of orders in short time. This also affects the price, so with this type of milling it is much lower. Also, better processing of the ends is obtained here; their surface is smooth and even, which cannot be achieved when processing manually.
Our equipment allows high-quality processing of plastic materials various types, used both in the advertising business and in industry, and for interior decoration. As mentioned above, plastic is in great demand, and for advertising business– this is a real find, giving a lot of opportunities. If necessary, our designers will develop a layout of a plastic product, offer fresh, original solutions for your advertising project. Sign System is always a reliable, responsible and beneficial partner for you!
