为了满足对钎(钻)具的需要和保证其高的工作性能,一些国外矿山机器生产厂家认为,具有最小的钎头基型结构是合理的,但对每一种基型钎头要规定能够改变其硬质合金的强度,硬质合金在钎头体突出部分的几何形状或尺寸的可能性。钎(钻)具生产厂根据广大用户的要求制造钎头,同时使生产的大部分钎头和世界最普通的定型凿岩机相匹配。例如有许多整体钎子、钎杆和可拆式钎头是瑞典桑德维克·科伦曼特(?)公司在20年的时间里和阿特拉斯·考普科公司合作研制的,因此,这些钎杆和
In order to meet the needs of brazing (drilling) and to ensure its high performance, some foreign mining machinery manufacturers that have the smallest bit base structure is reasonable, but for each type of brazing head to be able to provide Changing the strength of its cemented carbide, the possibility of the geometry or size of the cemented carbide in the protruding part of the bit body. Drill (drill) with the production plant according to the general requirements of the user to make bit, while making most of the production of bit and the world’s most common stereotypes drilling rig match. For example, there are many integrated brazing rods, drill rods and removable drill bits developed by Atlético Copco in the 20 years that Sandvik Corningman (Sweden) Therefore, these rods and rods
