Four Axis CNC Deep Hole Gun Drilling Machine is used for processing automobiles, motorcycles, oil pump, nozzle, engineering machinery, mining machinery, military industry and other industries, small and medium-sized deep hole axial workpiece of special equipment.
It can drill four workpieces at the same time, so the above model is especially suitable for large parts of the machine.
The machine tool equip the headstock, so the workpiece rotate and cutting tool rotate and feed at the same time, and the accuracy is very high.
Machine features
● Bed body and the box body is made of high quality cast iron casting, with good rigidity and stability.
● It doesn't need to return cutting tool in the process of drilling deep hole.
● It adopts CNC control system, a high degree of automation.
● Feed movement is driven by AC servo motor, and is driven by ball screw pair, and it is stepless speed regulation.
● It adopts sliding guide rail, moving parts bottom with special material, low speed running smoothly, without crawling.
● The drilling bar box is stepless speed regulation.
● The bearing of spindle and guideway adopt automatic intermittent lubrication, etc.
● High pressure cooling system adopts that frequency conversion motor drive gear pump, and the immersion cooler can control the oil temperature.
● It adopts automatic chip removal machine.
● It adopts all closed protective cover, and it is convenient to observe and good appearance.
● With multiple automatic monitoring device.

About ZK-A series single coordinates machine ,the workpiece outer diameter requirement.
ZK2102A series outer dimeter requirement | ||||
Item | The two taper plate against workpiece size (workpiece clamp position size) | Workpiece max outer position size (if the workpiece is ladder shaft, the max workpiece outer diameter dimension) | Spindle center distance | The workpiece diameter for the workpiece support frame position outer diameter dimension(it is used only for preposition) |
Four axis | Φ85mm | Φ110mm | 120mm | Φ100mm |
That is means that if the workpiece is ladder shaft, the workpiece outer diameter dimension is as above list, but two end workpiece outer diameter dimension is not more thanΦ85mm.
The workpiece support frame is used for prepositon of workpiece, when the workpiece is against,the support frame will separate the workpiece, this postion workpiece outer diameter is not more than 100mm.
And if your shaf is straight shaft,max workpiece outer diameter is not more than Φ85mm regardless single, double or four axis machine.

The accuracy of drilling hole
Accuracy of drilling hole: IT7-IT10 (good condition IT7-IT8; general IT9-IT10) ;
Roughness: Ra 0.4-3.2μm
Deviate of center axis:
A: 0.25mm/500mm (workpiece roate, length :diameter 100: 1, uniform material, suitable feed speed)
B: 0.5mm/1000mm (workpiece roate, length :diameter 100: 1, uniform material, suitable feed speed)
C: 0.5mm/500mm (workpiece not rotate, length :diameter 100: 1, uniform material, suitable feed speed)
D: 1mm/1000mm (workpiece not rotate, length :diameter 100: 1, uniform material, suitable feed speed)
Cutting tool life
Continuous cutting length 12-20m(not include special material)
And cutting tool can use 50times by The cutting tool resharpening , so the total length of cuttting can be more than 600m, good condition is more longer.
