Manufacturing of acrylic prototypes
Machined, silicone vacuum overmolded PMMA prototype
In the prototype industry, acrylic, also known as PMMA, is a transparent prototype material. Acrylic prototypes are mainly made by cnc processing. Acrylic has a relatively good transparency effect, which can reach 95% of the light transmittance.

Disadvantages of acrylic prototype:
Everyone knows that glass is very brittle, and acrylic is a kind of plexiglass. Therefore, its physical properties are also very brittle, and the shortcoming of poor toughness causes the acrylic to break accidentally. In the process of prototyping, this is the focus of attention. If the machining process cannot be completed, it can only be replaced with other materials, such as PC.
Advantages of acrylic prototype:
The important thing is high transparency. After polishing, the transparency can achieve the effect of full transparency. This effect is called plexiglass in the industry, which is unmatched by PC materials. Although PC is also transparent, the effect is not as good as that of acrylic.

Classification and maintenance of milling machines
The milling machine is a wide range of machine tools. The plane (horizontal plane, vertical plane) can be processed on the milling machine; Groove (keyway, T-slot, dovetail groove, etc.); Gear parts (gears, spline shafts, sprockets); Spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the revolving body and cut off the work.
CNC machine tools in processing aircraft parts
When machining on a CNC machine tool, manual tool control is not required, and the degree of automation is high. The benefits are obvious.
⑴ Reduced technical requirements for operators:
A senior worker of ordinary machine tools cannot be cultivated in a short time. However, the training time for a CNC employee who does not need programming is very short (for example, a CNC lathe worker only needs one week, and he will write simple processing programs). In addition, the parts processed by CNC workers on CNC machine tools have higher precision than those processed by ordinary workers on traditional machine tools, and it takes less time.
Custom Copper Precision Turning Parts
Our company is good at turning all kinds of copper parts, all kinds of valve parts, electrical bronze parts, brass nuts, mobile phone antennas, external knurling (straight grain / twill / net grain) and so on. The picture on the left shows a turned copper core. Used in valves, the material is C3604 fast-cutting steel brass, and the copper turning parts customized according to customer requirements are used as the valve stem and valve core. Used in valves of internationally renowned brands. Automatic turning and forming, after the head milling edge and the rod milling edge, the angle is 60 degrees. Slotted head. The outer diameter is 12.7mm, and the total length is 70mm. The forming turning tool has been used many times in the processing of this copper precision part. In order to solve the accuracy of the R angle and chamfering of the inner groove, CNC machining was initially adopted. Later, in order to save costs, automatic lathe processing was used.
