技术数据表

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

Small Diameter Holes (1 to 25mm) – High speed steel twist drills are sufficient. Peck drilling and a slow spiral allows for improved swarf removal.<\/li>\n
Large Diameter Holes (25mm or larger) – A slow spiral (low helix) drill or general purpose drill bit ground to a 118\u00b0 point angle with 9\u00b0 to 15\u00b0 lip clearance is recommended. The lip rake should be ground (dubbed off) and the web thinned.<\/span><\/span><\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\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。

To ensure efficient chip removal and prevent issues such as friction, heat build-up, and saw blockage, it is important to use a band saw, circular saw, or reciprocating saw with widely spaced teeth and adequate set. Proper clamping of the work table is also essential for preventing vibrations and ensuring smooth cutting. <\/span>Combination blades with a 0\u00b0 tooth rake and 3\u00b0 to 10\u00b0 tooth are generally the most effective for sawing in order to reduce frictional heat. That being said, hollow ground circular saw blades without set will yield smooth cuts up to 3\/4\u201d thickness.<\/span><\/p>\n

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。
