ZSK21 series CNC deep hole drilling machine
Processing technology
● It is a high-efficiency, high-precision, high-automation machine tool for drilling small holes with external chip removal method (gun drilling method).
● Processing quality that can only be guaranteed by drilling, expanding and reaming processes can be achieved through one continuous drilling.
● With its state-of-the-art control system, the ZSK21 series ensures precise drilling depth and diameter, guaranteeing impeccable quality for each hole. Whether you need standard drilling, gun drilling or BTA (Boring and Nesting Association) deep hole drilling, this machine handles all tasks with the utmost precision.
Precision
● The aperture accuracy is IT7-IT10.
● Surface roughness RA3.2-0.04μm.
● The straightness of the center line of the hole is ≤0.05mm per 100mm length.
