Deep hole tools are mainly used for deep hole drilling, reaming, boring and other deep hole processing. The guide rail of the deep hole tool bed adopts a double rectangular guide rail suitable for deep hole processing machine tools, which has large bearing capacity and good guiding accuracy; the guide rail has been quenched and has high wear resistance. Deep hole cutters are suitable for boring and rolling in machine tool manufacturing, locomotives, ships, coal machines, hydraulics, power machinery, pneumatic machinery and other industries, so that the workpiece roughness reaches 0.4-0.8μm. Deep-hole drills with rotating workpieces (or workpieces and cutters rotating at the same time) are similar to horizontal lathes. Deep hole drilling machines are universal, dedicated and modified by ordinary lathes. In order to facilitate cooling and chip removal, the layout of deep hole drilling machines is horizontal. The main parameter of deep hole drilling machines is the maximum drilling depth. However, because the processing depth often reaches more than ten meters or even tens of meters, in the processing process (guò chéng), the damage status of the tool is difficult to grasp (well-known and can be used), and it is usually judged by the operator based on his work experience. Deep hole cutters can choose (xuanze) the drill bits of multi-axis drilling machines. How should we choose?

1. Choose a good quantity of guaranteed production: At present, there are many manufacturers of drills for deep hole cutters, which are divided into China and imports.
2. Know the types and unique places of drill bits: the drill bits for printed board drilling include straight shank twist drill bits, fixed shank twist drill bits and fixed shank spade shape drill bits.
3. Pay attention to the material of the deep hole cutter. The material of the drill bit: the drill bit used for drilling the printed board generally adopts alloy, because the epoxy (Oxygen) glass material coated copper foil plate wears out the cutting tool quickly. Deep hole cutter When choosing the drill bit of a multi-axis drilling machine, you must make the correct selection according to the instructions. Only in this way can its performance be fully demonstrated.
