Description

Key Features

Dual‑spindle design with 140 mm spacing, one motor driving two spindles, maximum speed up to 6,000 rpm for high‑volume production.

product-418-255

Siemens CNC control as standard, stable servo feed system, easy operation and excellent repeatability; other CNC brands optional.

product-268-303

Combined gun drilling & pull reaming: reverse rotation between tool and workpiece for straightness; reverse feed direction for mirror‑quality reaming, same clamping for both processes.

Heavy‑duty structure: HT300 cast iron bed with double aging treatment, Taiwan HIWIN linear guides, NSK spindle bearings and Taiwan ball screws, ensuring roundness ≤0.003 mm and straightness ≤0.5 mm/m.

High‑pressure coolant system: up to 10 MPa pressure, 200 L/min flow, 20 μm filtration, large 1,000 L tank, stable cooling and chip removal for mirror surface Ra 0.05–0.2 μm.

Automatic & safe operation: hydraulic automatic clamping, cone disc positioning, automatic chip conveyor, fully enclosed safety guards, three sets of linked drill bar supports.
