正确选择和应用刀具刃口处理被认为是成功制造和正确使用硬质合金刀具的基本要素之一。本文对正确的刃口准备，特别是刃口珩磨的必要性有了基本的了解。讨论的目的是在尼龙磨料丝刷珩磨的过程，以及它如何影响作为最终产品的工具。它还确定了一些与制造相关的陷阱以及可能导致制造成本上升的问题。在几乎100%的硬质合金模具中，边缘处理是一个必要的过程。

Proper selection and application of cutting tool edge preparation is considered one of the basic ingredients for a successfully manufactured and correctly performing hardmetal-cutting tool. This paper develops a basic understanding of the need for proper cutting edge preparation, specifically, edge honing. The discussion is aimed at the process of nylon abrasive filament brush honing and how it affects the tool as an end product. It also identifies some of the manufacturing related pitfalls and the problems that can drive manufacturing costs. Edge preparation is a necessary process in nearly 100% of all hardmetal tooling.
