在淬火齿轮的磨削技术中，以切割速度低至0.3~5米/S为特征的磨削工艺正变得越来越重要。过去几年在这一领域开展的一些研究工作大大提高了对共同技术相互依存关系的认识。然而，在如此低的速度下，对于主要的切屑形成机制仍然缺乏了解。为了研究这些机理，进行了单粒划痕试验和研磨试验。确定了切割速度和切屑厚度是决定切屑形成过程的主要参数。这些结果可用于磨削工艺的设计和合适的磨具的开发。
Grinding processes characterised by cutting speeds as low as 0.3...5 m/s are becoming more and more important amongst abrasive technologies for finishing of hardened gears. A number of research work carried out in this area in the past few years has significantly improved the understanding of common technological interdependencies. However, there is still a lack of knowledge about the main chip formation mechanisms at such low speeds. In order to investigate these mechanisms, single grit scratching tests and grinding experiments have been performed. The cutting speed and the chip thickness were identified as main quantities determining the chip formation process. These results can be used for design of grinding processes and development of suitable abrasive tools.
