Oil drill collar dedicated deep hole drilling

A) The main processing machine performance and features:
1) The machine is a special hole in the drill collar for oil drilling bore design and manufacture of drilling. Design takes full account of the oil drill collar deep hole drilling processing technology and particularity.

2) The machine is suitable for deep hole drilling long workpieces, the aspect ratio of the hole drilling up to 150-200. Maximum drilling depth of the machine is 10-15 meters.
3) The machine is suitable for quenching after 42CrMo, 35CrMo, deep hole drilling of 4145 alloy material, boring. Workpiece hardness is generally not more than HB320 degrees.
4) When the machining of the drill collar, conventional cutting speed 60-100m / min. Feed speed 60-100mm / min. To drilling 71.4mm aperture, for example, workpiece speed 60r / min, tool speed 320r / min. Drilling feed speed 80-100mm / min. Drilling 9.7 meters long workpiece machining time in about two hours.
Thermal expansion 5) Taking into account the length of the workpiece deformation during deep drilling, designed to take the compensation structure.
6) The machine with the headstock and drill box, processing, while the relative rotation of the tool and the workpiece, the tool can only be rotated or just workpiece rotation.
BTA process for adoption (BTA method, cutting fluid through the oil cooler grant, arbor and the workpiece to the gap between the drilling reaches the cutting zone 7) drilling, lubrication, cooling the cutting area, wrap with chips through the drill pipe hole, Chip chip bucket into the box).
8) When the boring end of the coolant through the boring bar (box spindle drill tail) into the boring bar bore, the cutting tool to reach areas, lubrication, cooling the cutting area, wrap with chips at the head end of the workpiece by the chip flow into the bucket chip box.
9) using sequential numerical control device to control movement and actions of each machine, the accurate control of the depth of drilling or boring.
10) using a ring-shaped center frame with a motorized device for easy installation and adjustment of the workpiece, saving auxiliary time.
11) of the workpiece after straightening and drilling (less than bending 2mm), does not require machining cylindrical and face directly after installation. Auxiliary save time.
B) the machine main technical performance:
1) Drilling diameter range: Ф40-100mm.
2) The maximum bore diameter: Ф500mm.
3) The maximum workpiece depth: 10m --- 15m
4) Spindle center height: 500mm.
5) Working feed speed range (stepless): 10-400mm / min
6) Fast moving speed: 2m / min
7) coolant flow (4): 100, 200,300,400L / min
8) Cooling system rated pressure 2.5MPa
9) Main motor power: 30KW
10) drill box motor: 30KW
11) The total cooling pump motor power: 5.5x4 = 22KW
12) Feed motor power (AC servo): 7.5KW
13) Fast motor power: 5.5KW
