Multi-spindle drilling machine, good economic benefits, strong specificity

Product Details

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.

Two-spindle gun drilling machine  ZK2125X2C/1500

Drilling diameter: 5mm---25mm.

Drilling depth: 1500mm.

Worktable: laterally travelling, servo motors drive.

Drill stem: frequency  speed adjustment, rotating and feeding.

Drill bush: hydraulic drive, axially positioned and closely aligning to the workpiece.

Workpiece clamping: for shaft parts, use V-shaped iron fixture on which semicircle sleeve is set and hydraulic platen pressed; plate parts are positioned on the worktable and pressed by the platen.
