CNC Spiral drilling collar machine tool
Spiral drilling collar machine tool adopts three milling cutters to mill three spiral flutes of drill collar at the same time. Main technical content as follows:
Ⅰ, Work-piece Dimensions
1. Diameter of work-piece: Φ98～Φ280mm;2. Length of work-piece: ≤10,000mm;
3. Lead of spiral flute: Random;
4. The work-piece reach the standard of SY/T5144-1997.
Ⅱ Machine Structure
Machine’s basic structure is as drawing show.
1. Machine has the horizontal bed and chilled steel guide rail.
2. Under servo motor drive, the headstock can clamp drill collar turn the C direction motion, also can do the Z direction motion along the guide rail.
3. Three milling heads into 120 degrees. The radial motion of X1, X2, X3 can be controlled automatically by CNC controlled servo motor.
4.There are two V shape hydraulic self-centering center frames in the back of the milling cutter. No matter how the work-piece’s diameter, the “< >” shape jaw’s center will not change.
5. Two V shape hydraulic self-centering center frames can ensure the position of work-piece in the milling area and three milling cutter can work in the stable process system.
6. Under the middle of the machine bed, there is a V shape hydraulic center frame. It will fully retracted position when don’t use it. When most of processing work-piece come into the machine, it will automatic eject to support the work-piece, and reduce weight deformation deflection.
7. There is a feeding rest in the machine and can achieve to support the drill collar and load/unload the work-piece.
8. There is a automatic chip clear in the bottom of milling head.
9. This machine adopts all protective structure to ensure safety and good production conditions.
Ⅲ Machine’s Function
1. This machine can achieve three milling cutters process three 120°distribution spiral flute in the at the same time.（as shown in figure）；
2. To process the single arc flute drill collar, machine Z direction feed one motion trip, work-piece turning (C), control the X direction’s depth of cut.
3. To process the three arc flutes drill collar, machine longitudinal feed one motion trip, each of three cutters will cut out one flute of arc flutes, after longitudinal back, C direction dividing to cut another flute, to move times will finish the work-piece.

The machine is a special equipment for machining deep cylindrical hole of workpieces. It can be perfectly suited for drilling and boring through holes, blind and step holes in workpieces; such as ,spindle of various kinds of machines, many kinds of hydraulic oil cylinders and cylinders.
It can perform not only drilling and boring but also rolling pressing. The method of the internal-removal chip is adopted in drilling forward or outer-remover is adopted during boring.
The machine is strong in rigidity of the bed , high in precision , and wide in spindle speed range. Feed system is driven by D.C wide adjusting speed motor .It is suitable for various processing methods of machining deepholes . Fixture of the guide carriage and clamping force of the workpiece are performed by hydraulic device and indicated by meter.
Various change-model products of the series can be supplied according to users requirement.
