Description

ZKA***2 is CNC Deephole drilling machine suited for drilling *-D or *-D hole system. It is adopting chip removed outer, with high efficiency, accuracy and automatic to drill small-holes by "gun drilling "method. It can instead of counting, reaming by one drilling process, obtain sourcing accuracy. Bore accuracy is IT*-IT*0, roughness Ra3.**0.*4µm, linearity<=0.*5mm in **0mm length. It used widely in plastic and rubber industry, hydraulic mechanism, automobile and tractor, generator and aviation industry for machining deephole porforation; such as; cooling hole, eleheating hole, valve, distributor, pump, steering sharft, spindle, heat-exchanger plate etc.
