What is the CNC prototype, what is different from other prototypes

The CNC prototype model is a model made by using CNC machining technology, usually with CNC machine tools. The prototype model has a high position in industrial production, which can check the defects of product design and the difficulty of production, and initially evaluate the production cost and feasibility of the product. There are a lot of industries that are now used to make prototype models, including CNC machining, 3d printing and vacuum re-molding, so what is the difference between the prototype models made in these ways.

as we all know, several requirements of the prototype model are high precision, and the real size and production speed on the drawings should be restored as fast as possible, put the prototype model into the hands of the customer as soon as possible, saving time for the customer to develop the product, and the CNC prototype model seems to be created to meet these two conditions, the highly automated equipment can quickly produce prototypes, and the processing tools controlled by the central control computer can be processed according to the size of the design drawings.

compared with 3d printing, although the speed of the CNC prototype is not comparable, however, it has advantages in accuracy. Generally, the prototype accuracy printed by 3d is 0. About 1mm, and the accuracy of the CNC prototype can reach 0. 05mm, the CNC prototype accuracy processed by a better equipment can even reach 0. 01mm, this is incomparable to 3d printing.

compared with vacuum complex die, CNC machining has advantages in both speed and accuracy. Due to the influence of heat expansion and cold contraction, the precision of vacuum compound die prototype is generally 0. About 2mm.


Additionally, Shenzhen Tuowei Model Technologies Co., Ltd. has a few new features planned to roll out in the app to provide more convenience, comfort and options to our clients.
We humbly ask you to use cnc lathe price and we guarantee that you would be in a great delight with using the product.
