一、发兰工序的安排我国生产的硬质合金立铣刀刀体大部分是经过发兰的。发兰不但保护了钢体外表,而且美观。但是发兰工序安排在何时合适,乃是值得探索的。当发兰放在刃磨前刃面之后,刃磨过周齿后角时发现,前刃面有被支板明显划伤的划痕。痕迹呈沟槽状。高速钢支板本不能划伤硬质合金,可现已划伤,这说明硬质合金表面质量起了变化。划伤的前刃面与刃磨过而未经发兰的前刃面相比有明显不同,经发兰的
First, the process of hair blue process China’s production of cemented carbide end milling cutter body after most of the hair blue. Flange not only protect the appearance of the steel body, but also beautiful. However, it is worth exploring when the process of hair-setting is appropriate. When the hair Lan on the rake face before sharpening, sharpening weeks after the angle when the angle was found, the front blade surface has been scratched scratches scratches. Traces were grooved. This can not be scratched hard steel high-speed steel support, can be scratched, indicating that the surface quality of cemented carbide has changed. Scratched anterior blade and sharpened without the front of the blue blade is significantly different compared to the blue
