Gun drill drilling requires the use of special tools. Generally use a dedicated gun specially designed diamond drilling, the drill is based on the characteristics of the gun drill designed for drilling, use it to get the best drilling results. In addition, the machine can also be converted into ordinary diamond drilling gun, usually modified lathe, but better than a dedicated drilling machine to be worse. A good gun drilling machine should meet the following requirements:
　　1. rigidity, vibration. When modified with the lathe, special attention should be feed mechanism rigidity.
　　2. Have sufficient power.
　　3. With a sufficiently high spindle speed. Lathes maximum speed generally can not meet the small-diameter (d0 <10) deep hole machining speed requirements, therefore, modified the original machine is a need to increase the speed of the machine.
　　The feed mechanism to stabilize (preferably with Promise feed) Feed range fit. When converted, the general need to reconfigure hanging round, reducing the amount of feed grade.
　　5. The device has a cutting fluid and chip equipment to meet the requirements of
　　6. The need to equip about components:
　　A. adjustable feed overload
　　B. ensure the motor interlock machine tool coolant systems and synchronous start
　　C. oil pressure gauge
　　D. Cutting fluid filter
　　E. storage tanks of fuel gauge
