ZKB2102 is CNC Deephole drilling machine suited for drilling 3-D or 2-D hole system. It is adopting chip moved outer, with high dfficiency, high accuracy, drill small-holes by "gun-drilling "method, it can instead of drilling, counting, reaming by one drilling process obtain sourcing accuracy. Bord accuracy is 1T7-1T10, roughness ra3.2-0.4um mlinearity <=0.05mm in 100mm length. It is used widely in plastic and rubber industry, hydraulic mechanism, automobile and tractor, generator and aviation indutry for machining deephoile porforation, such as cooling hole, elecheating hole valve distributor, pump stering sharft, spindleheat-exchanger, plate, etc
