ZQK42 Series Crankshaft CNC Deep Hole Drilling Machine
The ZQK42 series crankshaft CNC deep hole drilling machine is a two-coordinate or three-coordinate CNC drilling machine specially designed for machining inclined and straight holes in crankshafts. This machine uses the external chip removal method (gun drilling) to complete deep hole machining of crankshafts in a single pass. The machine adopts a rotary worktable and adds a negative Z-axis, ensuring that multiple inclined oil holes and straight holes can be machined in a single clamping.
