Skiving and Burnishing Machine

Skiving and Burnishing Machine
GGK20 is the machine that specialized for small diameter hot steel pipe. The machine design refers to Sierra of USA,combined rough boring,precision skiving& burnishing into one process. High efficient and high precision. Mainly composed of bed, positioning seat, workpiece bracket, workpiece holder, oil feeder, mast bracket, mast box, feed system, cooling system, hydraulic system, PLC control system and other components.
The boring hole diameter range is: 30-200mm. And working length is :3000mm.(This parameter is for model GGK20x3000mm).

Product description:
1. Bed: The machine bed is made of integral casting bed, aging treatment, double rectangular guide rail, good rigidity and large carrying capacity.
2. Positioning seat: used for workpiece positioning and chip removal.
3. Workpiece bracket: Two sets of each machine tool, the main function is the workpiece auxiliary support, which is convenient for workpiece clamping, and its working position is lower than the workpiece clamping position.

4. Workpiece holder: It adopts V-shaped iron clasping structure on both sides to clamp the workpiece and resist cutting torque.

5. Oil feeder: used to support the tool and the mast and input coolant to the processing area.

6. Mast bracket: The mast damping sleeve is fixed on the bracket, and replaced with the mast damping sleeve when the mast is replaced. Easy replacement and good repeatability.

7. Mast box: The spindle motor is selected, the power is 60kW, the spindle has a wide range of constant power, and the second gear is used for stepless speed regulation. The speed range is 60-1000r/min. The spindle bearing adopts high-precision double-row cylindrical roller bearing and double-way thrust angular contact ball bearing, which makes the spindle rigid, high strength and good precision retention.
8. Automatic lubrication device: Lubricate the guide rail and lead screw pair.
9. Mast box feeding system: 7.75kW AC servo motor drive reducer is connected with the output gear-rack mechanism to transmit large torque.
10. Cooling system: The cooling system adopts the above-ground fuel tank structure. The cutting oil is taken away by the chain-type chip conveyor and then filtered through a filter (coarse filtration)-magnetic separator-fine filtration three-stage filtration treatment.
11. Hydraulic system: The main hydraulic components are selected from Taiwan brand.
