Abstract
本发明公开了一种具有涂层的硬质合金铣削刀片，特别适用于在干燥环境中的灰口铸铁、高合金化灰口铸铁、具有或不具有铸造表皮的蠕墨铸铁(CGI)的粗加工的或半精加工的铣削。所述的刀片具有低立方碳化物含量的WC－Co硬质合金、W合金化粘结相以及涂层，该涂层包括具有柱状晶粒的TiCxNy内层，接着是前刀面上的湿法喷砂的α－Al2O3层，以及刀后角边上的涂色顶层。本发明还涉及一种制造上述切削工具的方法。
Description
技术领域
本发明涉及一种具有涂层的硬质合金铣削刀片，特别适用于在干燥环境中的灰口铸铁、高合金化灰口铸铁、具有或不具有铸造表皮的蠕墨铸铁(CGI)的粗加工或半精加工铣削。
背景技术
当硬质合金切削刀片用于铸铁的加工时，切削刀刃会由于不同的磨损原理，如化学磨损以及磨损量而被磨损。另外，铣削切削刀刃通常会产生梳状裂缝。形成的梳状裂缝垂直于刀刃，且这是周期负荷和热负荷作用的结果。当梳状裂缝延伸至硬质合金体一定的深度后，刀刃就开始产生碎裂和断裂。
铸铁构件的显著特点就是：其硬表面区的结构相当大偏离其整体结构。其表面区通常包含硬夹杂物和模具上来的沙粒。这使得对铸铁的切削有很高的要求。同时，切削刀片应当能够应付大范围的切削条件，如不同的切削速度、切削深度和切削给进速度以及可控的外部条件，如工件的振动。
所有的这些因素要求切削刀片的多种性能。用于铣削铸铁的商用硬质合金刀片一般优选地相对于一种或两种所述的磨损类型进行优化。
美国专利No.5912051披露了一种特别适用于干铣削灰口铸铁的、具有涂层的切削刀片。
美国专利No.6062776披露了一种具有涂层的硬质合金切削刀片，其特别适用于在需要具有高硬度的硬质合金刀刃的切削加工中，湿铣削或干铣削具有或不具有磨蚀表面区的低合金钢和中合金钢，或不锈钢工件。所述的外部切削条件为：工件的复杂形状、振动、碎屑锻压、碎屑的再次切削等等。
美国专利No.6177178披露了一种特别适用于湿铣削和干铣削低合金钢和中合金钢的、具有涂层的硬质合金切削刀片。
WO 01/16388披露了一种具有涂层的刀片，其特别适用于在高的切削速度下，干铣削或湿铣削具有或不具有磨蚀表面区的低合金钢或中合金钢，以及在高的切削速度下，铣削淬硬钢。
美国专利No.6638609披露了一种具有涂层的铣削刀片，其特别适用于在低的或中等的切削速度下，干铣削具有或不具有铸皮(castskin)的灰口铸铁，以及在中等切削速度下，湿铣削具有或不具有铸皮的球墨铸铁和蠕墨铸铁。
美国专利申请2006/0115683披露了一种具有涂层的铣削刀片，其特别适用于在高的切削速度下，干铣削具有或不具有铸皮的灰口铸铁，以及在高的切削速度下，干铣削具有或不具有铸皮的球墨铸铁或蠕墨铸铁。所述的刀片为具有低含量立方碳化物的WC-Co硬质合金，以及高W-合金化粘结相，以及包含柱状晶粒的TiCxNy内层，其上为α-Al2O3湿喷砂层。
发明内容
本发明的目的在于提供一种较现有的刀具具有显著的优良的切削性能的、具有涂层的硬质合金切削刀，其特别适用于优选在较高的切削速度下，粗铣削灰口铸铁、高合金化灰口铸铁，以及蠕墨铸铁。
令人惊讶的发现，如果所述的刀片包括：具有W-合金化粘结相、良好平衡的化学组分以及一定晶粒尺寸的WC的硬质合金体，柱状TiCxNy-层和后处理的α-Al2O3顶层，则考虑到上述切削工艺中常见的不同的磨损类型，能够制得具有良好性能的铣削切削工具刀片。
根据本发明，具有涂层的切削刀片包含硬质合金体，其成分为7.3-7.9wt％的Co，优选7.5-7.7wt％的Co；1.0-2.0wt％、优选1.3-1.7wt％的Ta、Nb和Ti的金属立方碳化物，以及余量为WC，优选90.6-91.2wt％WC。Ti含量优选在工业杂质的水平上或为0。矫顽磁性，Hc的值应在13.8-15.7kA/m的范围内，优选为14.2-15.2kA/m内。
钴粘结相同W合金化。粘结相中W的含量如下式所示：
CW-比值＝磁性-％Co/wt-％Co
其中磁性-％Co为磁性Co的重量百分比，以及wt-％Co为硬质合金中Co的重量百分比。
CW-值为Co粘结相中W含量的函数。0.75-0.8的CW-值相当于粘结相中很高的W-含量，而CW-比值为1大体上相当于没有W-合金化。
本发明中所述的良好的切削性能在下述情况下得到：
