手板材料的选择不仅要满足客户对产品质量的要求，还要考虑设定周期内材料的成本和强度。当然，材料应根据手板的类型、工作方法、加工速度、主要故障形式等因素进行选择。

The selection of hand board materials should not only meet the customer's requirements for product quality, but also consider the cost and strength of the materials within the set cycle. Of course, materials should be selected based on factors such as the type of hand board, working method, processing speed, and main failure modes.

例如，冲压模具的主要故障形式是刃口磨损，应选择表面硬度高、耐磨性好的材料；冲压模具主要承受周期载荷，容易引起表面疲劳裂纹，导致表面剥落，应选择表面韧性好的材料；应选择摩擦系数特别低的材料；由于循环热应力，应选择热疲劳性强的材料。

For example, the main form of failure in stamping molds is blade wear, and materials with high surface hardness and good wear resistance should be selected; Stamping molds mainly bear cyclic loads, which can easily cause surface fatigue cracks and surface peeling. Therefore, materials with good surface toughness should be selected; Materials with particularly low friction coefficients should be selected; Due to cyclic thermal stress, materials with strong thermal fatigue should be selected.

济南手板生产加工需要注意以下几点：

The production and processing of hand boards in Jinan should pay attention to the following points:

（1）制定手板工艺路线，可根据工件需要分为两次加工。加工手板的外观和内壁，铣削基准，然后翻转180。夹紧，加工外表面和关键屏幕位置。如果外表面先加工，再加工内壁，则很难定位夹具进行二次加工。

(1) Develop a handicraft process route that can be divided into two processing steps according to the needs of the workpiece. Firstly, process the appearance and inner wall of the hand board, milling the benchmark, and then flip it 180 degrees. Clamping, machining the outer surface and key screen positions. If the outer surface is processed first and then the inner wall, it will be difficult to position the fixture for secondary processing.

(2)如果手板的壁厚只有1.5mm，加工外表面时容易变形破碎。如果在加工过的型腔中添加填料作为支撑。这样可以避免加工出口，然后填充石膏，否则成品和填料很难分离。

(2) If the wall thickness of the hand board is only 1.5mm, it is easy to deform and break when processing the outer surface. If filler is added as a support in the processed cavity. This can avoid processing exports and then filling with gypsum, otherwise it is difficult to separate the finished product and filler.

（3）修复修剪曲面，覆盖表面通孔位置，进行整体加工，然后在开槽处完成通孔加工，避免刀路起伏不平稳，切削力不均匀。

(3) Firstly, repair and trim the surface, cover the through-hole position on the surface, and perform overall machining. Then, complete through-hole machining at the slot to avoid uneven tool path fluctuations and cutting forces.

(4)记住！先铣出基准截角，以免翻转夹子时胚料调整方向错误。

(4) Remember! First, mill out the reference intercept to avoid the wrong direction of adjusting the blank when flipping the clamp.

(5)注意:在生产过程中，先模拟切割，检查正确后再处理，进行数控加工。

(5) Attention: During the production process, simulate cutting first, check for correctness, and then proceed with CNC machining.

手板上的各种部件应具有足够的强度和刚度，以防止使用过程中的损坏和变形。紧固件应采取防松动措施，以避免意外伤害操作人员。废物或工件在加工过程中不得飞行，影响操作人员的注意力，甚伤害操作人员。此外，避免切割部件的毛刺。还有什么事项就来我们网站http://m.metferro.com咨询！

The various components on the hand board should have sufficient strength and stiffness to prevent damage and deformation during use. Fasteners should take anti loosening measures to avoid accidental injury to operators. Waste or workpieces must not fly during the processing, affecting the attention of operators and even harming them. In addition, avoid burrs on cutting components.
