?技術(shù)優(yōu)勢(shì)
- Al 專用高韌性硬質(zhì)合金基體針對(duì)非鐵金屬加工優(yōu)化的合金配方，實(shí)現(xiàn)高韌性與低摩擦系數(shù)的平衡，減少加工中的刃口崩損與材料粘結(jié)風(fēng)險(xiǎn)，適配純鋁、鋁合金、鋁硅合金的切削工況。強(qiáng)化柄部設(shè)計(jì)提供更高剛性，振動(dòng)小，孔壁質(zhì)量穩(wěn)定。
- 140° 錐面減薄頂角 + 微凹主切削刃開放式點(diǎn)幾何設(shè)計(jì)，自定心能力良好，定位精準(zhǔn)，多數(shù)工況可無(wú)啄鉆連續(xù)加工，減少工序，提升加工效率。微凹主切削刃優(yōu)化切屑形成，降低加工負(fù)荷，延長(zhǎng)刀具壽命。
- 全拋光表面處理 + 螺旋槽設(shè)計(jì)螺旋槽、容屑槽、前刀面與后刀面全拋光處理，切屑排出順暢，適配鋁合金長(zhǎng)切屑加工特性，有效減少切屑堵塞與材料粘結(jié)風(fēng)險(xiǎn)。亮面設(shè)計(jì)降低摩擦系數(shù)，提升加工穩(wěn)定性與表面質(zhì)量。
- 內(nèi)冷直達(dá)切削區(qū) + 高效排屑高壓內(nèi)冷（≥15 bar）直接冷卻刀尖，降低切削溫度、沖刷切屑，適配鋁合金加工的低熔點(diǎn)特性，減少積屑瘤和刀具磨損。雙棱帶設(shè)計(jì)提高孔壁精度（圓度 / 直線度佳），減少摩擦與磨損Gühring KG。
