| Message: | Main purpose of Manual Boring Mill
This series of machine is of genenal-purpose, suitable for such operation as drilling, counter-boring,boring,reaming,spot-facing,tapping and milling etc. The horizontal milling and boring Machine is equipped with fixed facing plate on which radial facing slide can be radicaly feeded consequently to enable the machine to undertake boring of large-diameter hole, external cutting, end face turning and recessing, etc.
Features of Details
1. The overall layout of the machine tool is a single column, a side-hanging box, with a fixed flat rotating disc; the table moves longitudinally and laterally on the bed rail, and can realize 360 degree rotary movement; bed, slide, and column casting Cross walls are integrated between the walls to ensure the rigidity of the casting structure.
2. Three-point support of the spindle to achieve good spindle rigidity and accuracy retention.
The hollow shaft (boring sleeve) has three quenching bushes with a large interference fit on the front and back. The main shaft moves accurately back and forth in the bushing; the surface of the main shaft is nitrided and polished, with high surface hardness and durability.
3. The machine tool has a hanging button station for centralized operation, which is flexible and convenient. The spindle speed of the main movement and the feed of each axis are changed by hydraulic pre-selection.
4. The machine is equipped with electrical hydraulic interlocking device for the movements of each moving units,thus only allows one moving unit to move in only one moving mode (manual,automatic or rapid traverse) in the operation of the machine. Among each moving unit, the headstock elevating, and the table longitudinal and cross traversing and its rotation and clamping device are automatic release, while other undistributed movement will be in the state of clamping. In order to improve the performance of the machine, the axial moving of boring spindle and the radial......url:http://www.sfmachinetools.com |
