Borehole Drilling Machine

Borehole drilling machine

Machine brief:

• axis servo: Servo motor driven ball screw, used to control the feed of the drill box
• Drilling hole diameter range: φ25mm~φ65mm
• Boring hole diameter range: Φ40～Φ100mm   
• Max. Machining hole depth: 1000mm
• Max. Workpiece length: 1000mm

Accuracy :

• Hole deviation: 0.8mm/1000mm(workpiece is fixed)
• Roughness: Ra1.6～3.2um
• Dimensional accuracy: IT8～IT11

Machine features :

• Workpiece clamping:The spindle front-end of hydraulic tailstock and oil pressure head is equipped with cone disc, The hydraulic system controls the axial movement of tailstock spindle.Clamping and positioning of the workpiece automatically by using the chamfering angle at both ends of the cone plate and the workpiece.When the user orders the machine tool, it is necessary to provide the chamfering size and the size of the workpiece at both ends of the workpie.
• Guide rail: The machine is adopts slide guide rail.
• CNC system: KND
• Safety guard: The machine is without safety guard
• Drill box:It adopts frequency conversion motor to drive spindle rotation through synchronous belt and synchronous belt wheel,Stepless speed regulation can be realized.Max.rotary speed can be 700r/min,main motor power is 18.5kw.
• Tooling infeed system:It adopts the structure of Servo motor drive T screw through reducer,Stepless speed regulation can be realized.
• Drill bar support: 1group,Function：Supporting the drill bar/Ensure drilling accuracy/Reducing the drill bar vibration/It can meet the maximum drilling hole length diameter ratio 50:1;；It adopts drill bar support linkage mechanism.
• Hydraulic tailstock: It is used for pressing or loosening the workpiece, and the hydraulic system controls the axial movement of the spindle.
• Coolant system:It is composed of an oil tank and 1 groups of high pressure pumps.
