Many R & D Enterprises ， There will be many Precision machining Cooperative supplier 。 Whenever a new product comes on the market ， Will find Precision machining plant To make a model ， Used to check whether the design of drawings is reasonable ， And then carry out the mold opening production 。 This reduces the risk of new product development ， So doing Machining of mechanical parts Before ， What needs to be prepared ？

　　 First of all 3D Drawing ， It's also a stereogram 。 Precision machining Factory pass 3D Drawing ， Can understand the customer's Machining of mechanical parts Product size 、 Internal structure complexity ， To judge a Machining of mechanical parts Time and price required for product production 。 Generally speaking 3D Drawing ， Except in special cases ， That is, when making sheet metal processing ， Use 2D Just a picture 。

　　 Secondly ， A list is needed ， Tagging pairs Machining of mechanical parts Product material requirements and process selection ，CNC Machining 、3D Printing and vacuum copying Machining The way is Machining of mechanical parts Machining Common ways in the process ， And each kind of Machining There are specific requirements for the way ， Therefore In doing Machining of mechanical parts When you need it “ Suit one's measures to local conditions ”。

　　 In addition ， Precision machining plant It's also very important 。 Due to the limitation of strength ， Some of the order receiving factories are outward manufacturing ， It's easy to cause Drawing Information disclosure 。 Now customers are looking for suppliers ， It's very confidential 。 We Precision machining plant When receiving customers ， Will sign a confidentiality agreement 。

　　 Therefore ， In making Precision machining When ， Need preparation 3D Drawing 、 List and signing of confidentiality agreement ， So and Precision machining plant Only by cooperation can we achieve twice the result with half the effort 。
