摘要： A tip insert (4) for a cutter tool (1) comprises a body (10) of a wear-resistant material (e.g. cemented tungsten carbide) and a disc-like cutting member (11) of a more wear-resistant material (e.g. polycrystalline diamond, conveniently in the form of a layer bonded to a cemented tungsten carbide substrate) secured to the body, the disc-like cutting member having at one part of its periphery its edge shaped to form a flat face (16), so as to provide, with one of its major faces (14), two flat faces (14, 16) disposed in intersecting planes, and the disc-like cutting member (11) being bonded via these two flat faces to complementary plane faces (12, 13) on the body, and the disc-like cutting member having exposed, cutting faces (15) at that part of its periphery opposite to the bonded faces.
摘要翻译：用于刀具（1）的刀片插入件（4）包括耐磨材料（例如，硬质合金碳化物）的主体（10）和更耐磨材料的盘状切割构件（11）多晶金刚石，方便地以粘结在硬质合金基体上的层的形式固定在本体上，盘状切割件在其周边的一部分上具有形状，以形成一个平面（16），以便为了提供其一个主面（14）中的一个，设置在相交平面中的两个平面（14,16），并且盘状切割构件（11）通过这两个平面粘合到互补平面（12， 13），并且所述盘状切割构件在其与接合面相对的周边的那部分处具有暴露的切割面（15）。

发明人： Cave, John Andrew
IPC分类号： C04B35/10 , B23B27/14 , C04B35/48
CPC分类号： C04B35/119
摘要： Sintered ceramics, that may be of use in making the extremely hard tips of cutting tools, can be made from a ceramic matrix material having a ceramic refractory material incorporated therein.
The application seeks to provide an improved sintered ceramic material of this general type, wherein the refractory material consists of particles of significantly different sizes and which lie at least predominantly in at least two substantially different mean particle size ranges.
摘要翻译：可以用于制造切削刀具的极硬尖端的烧结陶瓷可以由其中结合有陶瓷耐火材料的陶瓷基体材料制成。本申请试图提供一种这种一般类型的改进的烧结陶瓷材料，其中耐火材料由具有显着不同尺寸的颗粒组成，并且至少主要在至少两个基本上不同的平均粒度范围内。
