There are several common processes for making hand board models: CNC hand board processing, 3D printing hand board, silica gel multi mold hand board, sheet metal hand board, low-pressure pouring hand board and so on. Today, Jinan hand board small edition to give you a brief introduction of CNC hand board processing steps and advantages.

手板模型，很多人又称之为首板模型。通俗点讲，即一件工业品设计完成后，并不是马上投入生产，而应该先根据图纸制作少量的模型出来，目的是可以提早看到成品的样品，如果不满意，再对图纸做出修改，直更终无异议后，再开始批量制造。这个少量的模型，就是口中的手板模型。

Handmade model, which many people call the headboard model. Generally speaking, when an industrial product is designed, it should not be put into production immediately, but a small number of models should be made according to the drawings. The purpose is to see the samples of finished products in advance. If not satisfied, the drawings should be modified until there is no objection, and then batch manufacturing can be started. This small number of models is the hand model in the mouth.

关于CNC手板加工工艺的步骤如下：

The process steps of CNC hand board are as follows:

1)谈好CNC加工以及交期，签订加工合同。

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

2)分析零件图及产品装配图，对零件进行工艺分析。

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

3)选择毛坯。

3) Select the blank.

4)CNC手板编程。

4) CNC hand board programming.

5)确定各工序的加工余量，计算工序尺寸及公差。

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

6)确定各工序所用的设备及刀具、夹具、量具和辅助工具。

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

7)确定切削用量及工时定额。

7) Determine the cutting amount and working hour quota.

8)确定各主要工序的技术要求及检验方法。

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

9)填写CNC手板打样工艺文件。

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

CNC手板加工有下列优点：

CNC hand plate processing has the following advantages:

1.不需要复杂的工装。如要改变零件的形状和尺寸，只需要修改零件加工程序，适用于新产品研制和改型。

1. Complex tooling is not required. If we want to change the shape and size of the parts, we only need to modify the processing procedure of the parts, which is suitable for the development and modification of new products.

2.手板加工质量稳定，加工精度高，重复精度高，适应高精度产品的加工要求。

2. The handboard processing quality is stable, the processing precision is high, the repetition precision is high, and it can meet the processing requirements of high-precision products.

3.批量生产的情况下生产效率较高，能减少生产准备、机床调整和工序检验的时间。

3. 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.

4.可加工常规方法难于加工的复杂型面，甚能加工一些无法观测的加工部位。

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