ZK21C series machines, horizontally arranged, are designed with gun drill and laterally travelling worktable. The V-shaped clamping mechanism is designed on the laterally travelling worktable to process concentric holes and eccentric holes of shaft components. For worktable travel, you can select numerical control or digital display. The basic parts of machine are HT300 precision casing. The feeding of drill stem adopts ball screw and rolling guide. The cooling oil flow is adjusted through frequency control. The machine is designed with oil temperature cooler and automatic chip cleaning system.
