CNC hand model processing technology, briefly describe the processing steps and advantages

The hand board model is also called the first board model by many people. Generally speaking, after the design of an industrial product is completed, it is not put into production immediately. Instead, a small number of models should be made according to the drawings in order to see the samples of the finished products in advance. If you are not satisfied, modify the drawings until there is no objection, and then start mass manufacturing. This small number of models is the hand model in the mouth.

There are several common processes for making hand board models: CNC hand board processing, 3D printing hand board, silica gel replica hand board, sheet metal hand board, low-pressure perfusion hand board, etc. Today, let's briefly describe the steps and advantages of CNC hand board processing.

The steps of CNC handboard processing technology are as follows:

1) Negotiate the CNC processing price and delivery time, and sign the processing contract.

2) Analyze the part drawing and product assembly drawing, and analyze the process of the parts.

3) Select the blank.

4) CNC hand board programming.

5) Determine the machining allowance of each process, and calculate the process dimension and tolerance.

6) Determine the equipment, tools, fixtures, measuring tools and auxiliary tools used in each process.

7) Determine cutting parameters and man hour quota.

8) Determine the technical requirements and inspection methods of each main process.

9) Fill in the process documents of CNC hand board proofing.

CNC handboard processing has the following advantages:

No complex tooling is required. If you want to change the shape and size of parts, you only need to modify the part processing program, which is suitable for new product development and modification.

The handboard has stable processing quality, high processing precision and high repetition precision, which can meet the processing requirements of high-precision products.

In the case of mass production, the production efficiency is high, which can reduce the time of production preparation, machine tool adjustment and process inspection.

It can process complex surfaces that are difficult to be processed by conventional methods, and even process some processing parts that cannot be observed.
