The utility model provides a diamond bit which is easy to cool and slag. The diamond bit of the utility model comprises a matrix and a cylindrical bit mounted on the base. The drill is equipped with a water discharge trough, and the extension direction of the water discharge trough is parallel to the axis of the bit, and the bottom end of the water discharge trough is extended to the lower end of the bit. The groove is exposed from the side of the drill bit, and the groove of the water discharging slag slot is deeper than the radius of the drill bit. In the drilling process, the slag produced by the bit grinding the workpiece will enter into the water slag tank and move up along the water drained trough, and eventually it is discharged from the side of the bit. In addition, the cooling water from the inlet of the base can flow down to the working face of the bit along the water discharge slot, and it is cold for the bit and the workpiece. But. Because the groove depth of the water discharging slag groove is larger than the radius of the drill bit, the part of the middle of the drill bit will not form a non grinded part, which will not affect the normal drilling.

一种金刚石钻头
本技术涉及到一种金刚石钻头。
技术介绍
金刚石钻头利用其端面的金刚石来磨削工件,来实现钻孔的目的,最常见的是圆筒状结构的钻头,但是,该种钻头在钻孔过程中要取出钻头,以便于取出料芯。现在有一种金刚石钻头,其端面为平面,利用该钻头可以在钻孔的过程中将料芯磨掉,因此省去了取出料芯的步骤。在实际工作中发现,上述端面为平面的金刚石钻头存在冷却效果差、渣料无法及时排出而影响钻孔质量的问题。
技术实现思路
本技术的目的是提出一种易于冷却和排渣的金刚石钻头。本技术的金刚石钻头包括基体和安装于基体上的圆柱形钻头,关键在于所述钻头设有通水排渣槽,所述通水排渣槽的延伸方向与钻头的轴线平行,通水排渣槽的底端延伸至钻头的下端面,通水排渣槽与基体所设有的进水口相通;所述通水排渣槽的槽口露出于钻头的侧面,通水排渣槽的槽深大于钻头的半径。在钻孔过程中,钻头磨削工件所产生的渣料会进入到通水排渣槽内,并沿着通水排渣槽向上移动,最终由钻头的侧面排出;另外,由基体的进水口所进入的冷却水,可以沿着通水排渣槽向下流到钻头的工作面,为钻头及工件冷却。由于通水排渣槽的槽深大于钻头的半径,因此在钻头中 ...
