The gun drilling machine is known as a deep hole drilling machine to drill workpiece a precision hole for metal cutting industry such as machine tool or die. This specific equipment supplied by Drillstar is special for its round bar material. The gun drilling machine is auto-feeding equipment with four spindles. It is a mass-production type with qualified automatic work piece-feeding system.
The equipment offers mass production in drilling a single size of round bar. Customer accesses efficiency while operating their works with Hong Ji gun drilling machine. On the other hand, with an auto-loading and unloading system, operator just needs to put work pieces on the conveyor. Then all work will be done in the equipment automatically.
