10 CNC இயந்திர முன்மாதிரிகளுக்கான பொருட்கள்

3D பிரிண்டிங்குடன் ஒப்பிடும்போது, CNC முன்மாதிரியின் மிகப்பெரிய நன்மை பொருட்களின் செழுமையும் நடைமுறைத்தன்மையும் ஆகும். முன்மாதிரியின் முக்கிய நோக்கம் தயாரிப்பு வடிவமைப்பின் சாத்தியத்தை சரிபார்க்க வேண்டும், எனவே முன்மாதிரியின் பொருட்களும் மிகவும் குறிப்பிட்டவை. ஒவ்வொரு நிறுவனத்தின் தயாரிப்புகளும் வேறுபட்டவை, மற்றும் செய்ய வேண்டிய முன்மாதிரி மாதிரிகளும் வேறுபட்டவை. எனவே, உற்பத்தி பொருட்கள் வேறுபட்டிருக்கலாம், ஆனால் முக்கிய செயலாக்கப் பொருட்களில் பின்வருவன அடங்கும்:

2. பிசி: Material with good strength, toughness and transparency, suitable for the production of Lens and fine structure parts. கூடுதலாக, glass fiber is added to improve the steel and heat resistance of the board, which can be used to make parts that need to maintain high rigidity in a high temperature environment. PC also has UL94-V0 fire rating;

3. PMMA: Namely acrylic, or plexiglass. It is a good transparent part, the material with the best transparency can be made with surface treatment such as dyeing, மின்முலாம் பூசுதல், spraying, and screen printing. The welding strength is acceptable, but fragility is its weak point, and it is not suitable for use in vulnerable places such as hooks;

4. பிபி: Translucent material, good impact resistance, excellent flexibility, can be applied to products with strict impact resistance conditions. போன்ற: automotive supplies, half-folding packaging boxes, முதலியன.


5. PA66+GF30: PA66+GF30 is not a model, it is a general code for PA66 plastic materials with 30% glass fiber. High strength, special thermal stability, hydrolysis resistance, suitable for auto parts, mechanical parts, முதலியன. It is used as a shield for mechanical parts that require high rigidity and dimensional stability. Red phosphorus flame retardant has long-term stability and excellent mechanical processing performance;

6. POM: It is called polymethine raw material in Chinese, also known as polyoxymethine raw material. It is often called Saigang in the prototype industry. The regular molecular structure and crystallinity make its physical and mechanical properties very excellent, and it is called metal plastic. In the prototype model, it is suitable for high-strength workpieces, such as gears, தண்டுகள், brackets, முதலியன;

7. டெஃப்ளான்: The chemical name is polytetrafluoroethylene (PTFE for short), which is generally called "non-stick coating" or "easy to clean material". This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. அதே நேரத்தில், PTFE has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used for lubrication and become an ideal coating for easy cleaning of the inner layer of water pipes;

8. Aluminum alloy: Aluminum alloy is the most widely used non-ferrous metal structural material in prototype models, and has been widely used in aviation, விண்வெளி, automotive, மருத்துவ, and ship prototype models. தற்போது, aluminum alloy is the most used alloy in prototypes. The advantages are easy processing and forming, good rigidity, and rich anode coloring;

9. Magnesium alloy: light weight and good strength, it is a favorite material for consumer 3C. The disadvantage is that magnesium is a flammable metal, and environmental control is very important during machining. The manufacturing process of magnesium alloy model is highly dangerous, and there are many machining processes after die-casting during production, which is a high-cost application material;

10. பித்தளை: Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of two or more elements, it is called special brass. Brass has strong wear resistance. Brass is often used in prototype models to replace materials that are difficult to engrave and mill, such as stainless steel. After polishing and electroplating, the surface effect and feel are very close to stainless steel.
