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，很多人又稱之為首板模型。通俗點講，即一件工業(yè)品設(shè)計完成后，并不是馬上投入生產(chǎn)，而應(yīng)該先根據(jù)圖紙制作少量的模型出來，目的是可以提早看到成品的樣品，如果不滿意，再對圖紙做出修改，直至更終無異議后，再開始批量制造。這個少量的模型，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.

關(guān)于CNC手板加工工藝的步驟如下：

The process steps of CNC hand board are as follows:

1)談好CNC加工價格以及交期，簽訂加工合同。

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

2)分析零件圖及產(chǎn)品裝配圖，對零件進行工藝分析。

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

3)選擇毛坯。

3) Select the blank.

4)CNC手板編程。

4) CNC hand board programming.

5)確定各工序的加工余量，計算工序尺寸及公差。

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

6)確定各工序所用的設(shè)備及刀具、夾具、量具和輔助工具。

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

7)確定切削用量及工時定額。

7) Determine the cutting amount and working hour quota.

8)確定各主要工序的技術(shù)要求及檢驗方法。

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

9)填寫CNC手板打樣工藝文件。

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

CNC手板加工有下列優(yōu)點：

CNC hand plate processing has the following advantages:

1.不需要復雜的工裝。如要改變零件的形狀和尺寸，只需要修改零件加工程序，適用于新產(chǎn)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.手板加工質(zhì)量穩(wěn)定，加工精度高，重復精度高，適應(yīng)高精度產(chǎn)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.批量生產(chǎn)的情況下生產(chǎn)效率較高，能減少生產(chǎn)準備、機床調(diào)整和工序檢驗的時間。

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.可加工常規(guī)方法難于加工的復雜型面，甚至能加工一些無法觀測的加工部位。

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.
