The support is made of black POM material (polymethylene), characterized by a U-shaped overall structure with a matte surface finish, which ensures a compact and aerodynamic appearance. The upper part has an arc-shaped opening for firmly attaching the cylindrical components, while the sides have reinforcing ribs and numerous mounting holes, which balance structural resistance and assembly flexibility. The base has a symmetrical L-shaped shape that ensures excellent stability.
In the processing phase, we use the highly pure POM black card as raw material. First, the precision cutting is carried out with the help of a CNC cutter to ensure that that the blank measurement is checked within a period of ± 0,1 mm from the design error of the drawing. Then fix the blank on the working table of the CNC machining center and set up the CNC Milling process with high precision:
Raw milling phase: use of large diameter flat foundry knife to quickly remove excess material, pre-treat the C-shaped contour and the upper and lower cable structures and reasonably control the cut amount to prevent deformation of the POM material;
Semi-precision milling phase: replace the cutting tool with medium diameter to achieve the semi-precision machining on the contour, performing the mounting surface and the side tip and evenly reserving the precision milling freedom;
Precision milling: use of small diameter ball cutters and flat end cutters for fine machining of arc edges, Mounting holes and positioning slots controlled for flatness, coaxiality of holes and width tolerances of slots up to ± 0,01 mm, to ensure precise assembly of the components of the aircraft model;
Our Precision Milling Service optimizes the cutting parameters specifically for the thermal sensitivity and low melting point properties of POM materials: a low cutting speed in combination with a cold air cooling system for avoiding material deformation or melt adhesion due to heat, without additional surface treatments that maintain the black, opaque texture immediately after milling, Simplify the process and ensure the consistency of the appearance.
As a professional manufacturer of CNC machining services, Dongguan Shengpeng Precision Technology Co., Ltd. can offer an effective CNC Milling Service, by supporting a complete adjustment: be it the adjustment of dimensions, the replacement of the material (such as aluminum alloy, stainless steel, other engineering plastics, etc.) or the changes of the surface treatment process (such as sanding, anodizing, dyeing, etc.), all can be realized upon request. Our metal fabrication service can meet your individual needs in various scenarios and provide you with a one-stop-shop solution from design to delivery.
