我来贴一段维氏的内部培训资料里关于维氏加工方式的介绍, 从研磨, 抛光,到开刃, 这3部分是连续的, 无漏发。 如果需要, 有劳e文好的刀友帮帮忙翻译一下。 因为是我手打的, 如有错误有劳指出,我会及时修正。 感谢该资料的提供者: 维氏钢刀(中国)零售发展经理 蔡先生。
该材料为: VICTORINOX, Everything you need to know about Multi-tools and cutlery

Grinding, polishing, sharpening
After the hardening prosess the surace is machined. In the knife industry this machining process is known as grinding. The process requires plenty of water for cooling to prevent excessive temperatures. The overheating provokes changes in the structure of the steel leading to a reduction of the rust-resistance, hardness and edge-holding ability. (If rgrinding work is required later on and the blade is overheated in some places during the regrinding process, there is a expansion of the steel only in these spots. During the cooling of and reverse expansion process, cracks will develop at these overheated spots which can lead to breakage of the blade during use.)
The surfaces are then finely polished, this requires a homogeneous microstructure and very high degree of purity. Finally, the cutting edge of the blade is sharpened to give the cutting tool its sharpness and functionality.
Sharpening is performed on either a sharpening stone or a polishing wheel. The cutting angle is checked using a laser.
The outstanding precision of modern automated machinery makes it possible to produce very high-quality knives at an affordable price. |
