Machine processing capability: BrandGuanLu ModelTSK2150×8000mm Country of originChina Solid drilling diameter rangeΦ50～Φ120mm Boring diameter rangeΦ120～Φ500mm Max. Hole drilling depth8000mm Workpiece length range500-8000mm Machine processing method: Solid drilling modeBTA drilling method(chips removed through drilling bar) Hole boring processChips removed through workpiece’s cored hole. Infeeding methodIt adopts the servo motor,servo reducer ,rack and pinion structure to drive the cutter tool infeed,the stepless speed regulation can be realized. Machine Machining Precision: Drilling:Skewness (workpiece can rotary):0.5mm/1000mm(Length to diameter ratio no more than 100:1) Drilling: Hole accuracy: IT8-11, Surface roughness: Ra3.2-6.3um Precision boring: Hole accuracy: IT8-9, Surface roughness: Ra1.6-3.2um

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.
