This machine is specially for the cylinder-shaped workpiece, choose different cutter can obtain different accuracy requirement. Our normal machine is semi automatic control, you can choose CNC control also(when works on blind holes, CNC control is suggested). Customer can choose drilling bar box(it can enhance efficient and accuracy), please indicate when place order. Our machine adopts supper cast iron(HT300), wood type cast molds, machine bed material is uniform, good looking appearance, good rigidity, accuracy keeping is long span, railway surface is quenched and ground.
