材料选择指南

这些指导方针旨在为那些不熟悉塑料工作的人提供一个总体概述，但重要的是要注意，最佳加工条件可能取决于正在生产的特定部件。bob手机在线登录-综合客户端加工塑料时的一个关键考虑因素是塑料通常比金属更软，这使得在加工期间和加工后bob手机在线登录-综合客户端保持精确公差更具挑战性。工程塑料部件的目标公差为+/- .05毫米，尽管使用某些尺寸更稳定的材料可以实现更小的公差。

如果您在加工过程中遇到任何问题，例如不良的表面抛光或意想不到的材料行为，请参阅故障排除快速参考，以指导如何解决这些问题。通过了解塑料的独特特性并使用适当的加工技术，您可以在工作中获得高质量的结果。bob手机在线登录-综合客户端

如果在加工过程中冷却剂是必要的，以确保最佳的表面光洁度，坚持接近公差和减少材料燃烧。水溶性油通常被认为是最有效的。石油基冷却液可能适用于某些塑料，但是，它们可能导致聚碳酸酯或丙烯酸等非晶态工程塑料的环境应力开裂。bob竞技游戏下载bob手机在线登录-综合客户端在这种情况下，纯净水或压缩空气往往是更合适的选择。

A combination of peck drilling and cooling liquid should be used in order to allow the plastic to cool when being drilled. It is also advised to utilize drills with a thinned web to further restrict friction and heat generation. The hole should be drilled step wise, successively increasing the diameter of the drill and potentially expanded with a boring tool for an improved finish. An example of this would be attempting to reach a bore diameter of 55mm, first drilling with a \u00f810mm and \u00f825mm drill bit and finishing with either a \u00f855mm drill or completing with a boring tool.<\/p>\n

                    为了使塑料在被钻孔时冷却下来，应该使用轻钻和冷却液的组合。还建议使用带薄网的钻头，以进一步限制摩擦和热量的产生。应逐步钻孔，依次增加钻头的直径，并有可能使用镗孔工具扩大以提高光洁度。例如，若想达到55mm的井眼直径，首先使用ø10mm和ø25mm钻头进行钻进，最后使用ø55mm钻头或镗孔工具完成钻进。

                    为了限制swarf的积累，需要考虑以下因素:

                        • 小直径孔(1 ~ 25mm) -高速钢麻花钻足够。Peck钻井和缓慢螺旋可以改善剥皮去除。
                        • 大直径孔(25mm或更大)-推荐使用慢螺旋(低螺旋)钻头或通用钻头，磨成118°点角，唇间隙9°至15°。唇耙应磨平(去掉)，并将网削薄。

      为了确保有效的切屑清除，并防止摩擦、热积聚和锯片堵塞等问题，使用带锯、圆锯或具有宽齿间距和足够设置的往复锯是很重要的。工作台的正确夹紧对于防止振动和确保顺利切削也是必不可少的。具有0°齿耙和3°至10°齿的组合刀片通常是最有效的锯切，以减少摩擦热。也就是说，没有设置的空心地面圆锯片将产生3/4“厚度的光滑切割。
