ZSK2302/ ZSK2303 Three-axis CNC Deep Hole Drilling Machine

Deep hole processing for drilling three coordinates.

It is a high-efficiency, high-precision, high-automation machine tool that uses external chip removal method (gun drilling method) to drill small holes.

Processing quality that can be guaranteed by drilling, expanding and reaming processes can be achieved through one continuous drilling.
