Generalmachine layout and main parts structural detail:
1. Machine components
The machine tool is composed by the bed body, head of a bed frame, feeding oiler, oiler feeding system, boring bar, boring bar drag plate feeding system, the work support, boring bar support, work calipers, chip removal filter system, hydraulic system, cooling system, CNC electrical system, automatic lubrication system and other major parts.
2. Boring bar box
Boring rod box is box structure, drive by 70 KW ac servo motorthrough the synchronous belt, rated speed of motor is 1500r / min, top speed is 4500 r/min, the motor is fixed on the upper of the boring bar box, and drive with the boring bar box through the synchronous belt, good driving rigidity, good vibration resistance. Select 70 KW ac servo motor of Germany Siemens.
3. Boring bar support
The machine tool has three boring bar brackets, and boring bar support plays a part in increasing the stiffness of the boring bar, reducing the vibration and stability of the boring bar, make it more smoothly when turns.
Boring bar bracket adopts the centripetal ball bearing support, to ensure not only the accuracy of axial but also the accuracy of radial, using the rotation of the bearing sets makes small rotational resistance and steady running. Manual lubrication pump is mounted on the boring bar bracket, to regularly provide lubrication for rotating assembly.
4. Workpiece calipers
The machine tool is equipped with two hydraulic workpiece calipers, the purpose of the workpiece calipers is to load and unload workpieces conveniently, at the same time to guarantee the stability of workpiece when processing.
5. Work support
The machine tool is equipped with two work supports, bracket with V type rack can adjust the height from top to bottom, in order to suit the diameters of different work-pieces, head frame to loosen the work-piece when unloading work-pieces, and the work-pieces will fall into the center of the V type roller.
6.Cooling system
The cooling system is on the side of the machine tool, the main parts are the fuel tank, pump station, oil pipe, automatic chip removal machine and magnetic separator. The roles of the coolant are cooling and removing chips.
