Twin Barrel Hole Drilling And Boring Machine

Twin barrel hole drilling and boring machine

1.1 Machine processing step of Twin barrel hole drilling and boring machine:

Soild drilling Φ45mm → pull boring Φ50.4mm → fine boring Φ51mm → machining hole from Φ51mm to Φ71mm → change the toolings → machining the hole from Φ71mm to Φ105mm → Move the workpiece and repeat the above steps to machine the next hole.

1.2 Machining method of Twin barrel hole drilling and boring machine:

Workpiece rotate,tool fix and tool feed; Workpiece rotate, tool rotate and feed.

1.3 Cavity hole:

The CNC system controls the tool movement in the X direction (tool expansion/contraction) and Z direction, with simultaneous two-axis motion of the X and Z axes. The tool is guided by the pilot hole in the workpiece. The entire tool retracts in the Z direction while the cutter head moves in the X direction to machine the cavity hole. Cutting oil is supplied through the oil feeder, passes through the clearance between the boring bar and the hole wall to reach the cutting edge, cooling and lubricating the tool. The cutting oil carries chips forward into the chip hopper (toward the headstock).

1.4 BTA drilling:

In the BTA drilling method, cutting oil is supplied to the tool through the oil pressure head and the clearance between the boring bar and the hole wall, and carries chips out through the inner bore of the boring bar.

1.5 Push boring:

Cutting oil is supplied to the tool through the oil feeder and the clearance between the boring bar and the hole wall, and carries chips out through the pilot hole of the workpiece; during machining, the tool moves toward the headstock.

1.6 Pull boring:

The boring bar passes through the workpiece bore to the front end of the headstock spindle, and then the cutting tool is mounted. During machining, the tool moves away from the headstock. Cutting oil is supplied to the tool through the oil pressure head and the clearance between the boring bar and the hole wall, and carries chips out through the workpiece bore toward the headstock.
