济南注塑模具过度抛光的后果

来源:http://www.sdlqmj.com 日期:2020-11-16 发布人:liqiang 浏览次数:
抛光问题一直是模具企业无法根本解决的一个难题。注塑模具钢需要一个很好的抛光技能来体现材料本质的性能,但上海奎星已达到高品质顾客企业所认同的研磨技术的要求。日益精进的技术,创造出无法仿效的镜面精加工效果,从对使用钢材的建议到微小孔的解决等问题,及各种形状复杂的精密零件。
Polishing problem has always been a difficult problem that mold enterprises can not fundamentally solve. Injection mold steel needs a good polishing skills to reflect the nature of the material performance, but Shanghai Kuixing has reached the grinding technology requirements recognized by high-quality customers and enterprises. Increasingly sophisticated technology has created a mirror finishing effect that can not be imitated, from the suggestion of using steel to the solution of micro hole, and various complex shape precision parts.
抛光中遇到的问题就是“抛光过度”,抛光过度是指抛光时间越长,注塑模具表面质量越差。发生抛光过度时有两种现象,即“桔皮”和“微坑”,抛光过度多发生于机械抛光。
The biggest problem in polishing is "over polishing", which means that the longer the polishing time is, the worse the surface quality of injection mold is. There are two kinds of phenomena when excessive polishing occurs, namely "orange peel" and "micro pit".
“桔皮”,不规则、粗糙的表面被称为“桔皮”,产生“桔皮”有许多不同的原因。更常见的原因是由于抛光压力过大及抛光时间过长,以及抛光方法不当等。

The irregular and rough surface of "orange peel" is called "orange peel". There are many different reasons for "orange peel". The most common reason is that the polishing pressure is too high, the polishing time is too long, and the polishing method is improper.
发现表面质量不好,许多人就会增加抛光压力,并延长抛光时间,加上抛光流程的不当,往往会使表面质量变得更差。
If the surface quality is not good, many people will increase the polishing pressure and prolong the polishing time. In addition, the improper polishing process will make the surface quality worse.
“微坑”,“微坑”或“砂孔”的形成是由于钢种的非金属夹杂物(杂质),通常是硬而脆的氧化物;在抛光过程中从钢材表面被拉出,形成“微坑”或“砂孔”。主要影响因素如下:
The formation of "micro pits", "micro pits" or "sand holes" is due to the non-metallic inclusions (impurities) of steel grades, which are usually hard and brittle oxides; they are pulled out from the steel surface during polishing to form "micro pits" or "sand holes". The main influencing factors are as follows:
1、抛光压力和抛光时长;
1. Polishing pressure and polishing time;
2、钢材的纯净度,特别是硬性夹杂物(杂质)的含量;
2. The purity of steel, especially the content of hard inclusions (impurities);
3、抛光工具;
3. Polishing tools;
4、研磨材料。
4. Abrasive materials.
