1.1 Machine processing capacity :

Drill hole diameter range: Φ30~Φ100mm

Boring hole diameter range: Φ40~Φ200mm

Processing depth range : 1000mm~10000mm

Workpiece length range : 1000mm~10000mm

Workpiece OD range : Φ89~Φ260mm

1.2 Machine functions:

Drilling and boring two functions .

Drilling hole : BTA drilling method , remove the cutting chips from the rear end through drilling bar .

Boring hole : Adopt push boring method , remove the cutting chips forward through the basic hole of workpiece .

1.3 Machine main structure:

1.3.1 Main parts:

Machine bed, Headstock, 2sets workpiece carrier, Oil pressure head, 4sets drill bar support rest , Drill box , Sliding guide rail , Rack and Pinion, Coolant system, FANUC 0iTF plus CNC system, Electric cabinet, 3sets of four-point circular center rest , 1set of three-point center rest  .

Headstock :

Used for driving the workpiece to rotate, 12-stage speed regulation by manual,adopt 30kw three phase asynchronous  motor driving the spindle to rotate through belt and gear box . The manual three-jaw chuck is assembled in front end of headstock, used for clamping the workpiece.

The main motor connect with I axis directly through flexible coupling , to prevent from drive slippage problem when transfer large torque ; I axis as well as the pinion on it are made of materials with high tensile strength and high yield strength.
