Advantages and costs of rapid prototyping CNC machining

CNC machining
is the use of raw materials directly through CNC CNC machine tools to produce the required samples.CNC machining speed, sample surface quality is good, after the completion of surface spraying, screen printing and electroplating process, and mold production of the product effect is very close.CNC machining can use ABS, POM, PC, PA, metal and other different materials to process samples to meet different customer needs.Especially, the samples processed with high quality and good density of engineering materials have very good strength and toughness.The handboard model manufacturers with competitive advantages should have the following advantages

 
  1. The rapid prototyping technology should be advanced. If the structure is complex and there are a certain number of prototypes, silica gel vacuum casting prototyping technology can be used; if the prototype material is particularly firm, CNC can be used for prototyping.
 
  1. It is the equipment for rapid prototyping. For example, low-voltage perfusion equipment is used for small and medium batch production.There are also fully automatic vacuum molding machines, silica gel vacuum pouring equipment, imported CNC machining centers, 3D printing machines and some fully automatic machining machines.
 
  1. The rapid prototype belongs to the processing industry. In addition to the processing and equipment, it needs thoughtful service to make the whole prototype production process coherent.Control model quality of rapid prototyping customers.That's what a reliable, fast prototyping plant is supposed to do.
 
  1. There is no formal registration of the relevant documents, the factory, and the degree of confidentiality of customer information, this is often done for a long time the rapid prototype plant is more reliable, after all, after the test of time.

Cost of CNC rapid prototyping:
 
  1. CNC machining consumables directly use real materials such as ABS and PP, with low material cost;
 
  1. However, CNC process requires programming and splitting. Generally, a CNC equipment needs 3-4 personnel, which results in high labor cost.Therefore, the cost of CNC rapid prototype model mainly depends on the complexity of parts and material consumption. The more complex the part, the more work to be split and programmed, the more complex the post-processing process, the more man-hours required, and the higher the production cost.


CNC prototyping features are as follows:    

1. High processing precision and stable processing quality;   

2. Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed;   

3, when the processing parts change, generally only need to change the NC program, can save production preparation time;  

4, the machine itself of high precision, rigidity, can choose a favorable processing dosage, high productivity (generally 3 to 5 times of the ordinary machine tools);   

5, the high degree of automation machine tool, can reduce the labor intensity;   

6. Mass production, easy to control product quality;

The advantages of CNC prototyping include:   
 
Direct use of plastic or hardware materials, material cost is low, wide selection of materials.The machine equipment performance is stable, the operation is simple, may carry on the partial decomposition appropriately, is specially suitable for the processing large size and the structure is relatively simple the component.

Common materials for CNC prototype processing: ABS, PC, POM, PP, PMMA, nylon, bakelwood, aluminum alloy, zinc alloy, low carbon steel, copper, stainless steel, etc. In addition, teflon, PBT, PPS, PEET, etc., can be used as processing materials.
