据报导,Guhfing公司的涂层S—钻尖钻头的寿命提高了300%,这种金黄色的涂层是用新的低温等离子涂复工艺涂复的,它不会引起钻头变形和生产热应力。涂层只有几微米厚,表面硬度达HV2000,高于硬质合金的硬度。涂层除能减少后面和刃带的磨损外,还能大大减少切削刃的磨损。由于涂层具有无磨擦的特性,前面上的月牙洼磨损极小,孔的光洁度得到改善,积屑瘤和冷焊现象得以消除。据介绍,用这种钻头加工孔,可取消铰孔工序。
It has been reported that Guhfing’s coated S-drill tip has a 300% longer life, and this golden-yellow coating is coated with a new low temperature plasma coating process that does not cause bit distortion and thermal stress . Coating only a few microns thick, the surface hardness of HV2000, higher than the hardness of cemented carbide. In addition to reducing the amount of back and land wear, the coating also greatly reduces cutting edge wear. Due to the non-abrasive nature of the coating, the crater on the front has minimal wear, the finish of the hole is improved, and the build-up and cold welding phenomena are eliminated. According to reports, with this drill hole processing, reaming process can be canceled.
