Hba68 Table Type CNC Horizontal Milling and Boring Machine

APPLICATION
HBA68 series is a combination of rotary table + main machine, shaped in "T", i.e., table movement is perpendicular to spindle/column movement direction, which is suitable for batch machining of hole plane of small /medium-sized parts, such as various boxes, frames, brackets, gearboxes, etc. The machine can carry out boring, drilling,tapping, groove milling, plane milling, etc. High productivity, various processes for complex parts could be completed in a single set-up.
The main performance characteristics:

1. Fundamental parts (bed, column, headstock, ram, etc.) are of high quality cast iron, with resin sand molding and aging treatment. Bed is of closed box structure, with reasonable arrangement of reinforcement ribs and multi-point support.
2. Column adopts integral gantry frame of heat symmetrical structure with reasonable distribution of cavities, with sufficient bending and torsion strength to reduce the impact of thermal deformation on the machining accuracy due to temperature change.
3. Headstock is placed between the portal frame type columns, hanging in the front, of heat-symmetric structure which means less thermal deformation and less thermal impact on working accuracy,. With high n overall rigidity, good stability and good vibration absorption it is suitable for heavy cutting.
4. Spindle bearing-imported famous brand high-precision angular contact ball bearing with grease lubrication. Cooling sleeve is adopted for circulate cooling to control the temperature rise of the bearing at high speed, to ensure the spindle stability. Temperature sensor is adopted to measure the temperature of the outer ring of the spindle bearing with high temperature alarm protection.
5. X, Y, Z, V adopt high-precision hardened guide way with PTFE coating, of large load-bearing capacity, low friction, strong anti-vibration, high positioning accuracy. Guide way pair adopts regular lubrication by gear oil distributor.
6. X, Y, Z, V, W axis adopt preloaded ball screw drive.
7. Headstock elevation adopts double screw-double motor synchronous drive. Headstock balance adopts double screw balancing instead of balance weight. Less weight on moving parts can effectively avoid the impact of heavy balance weight on accuracy during rapid moving. So as to achieve a better dynamic performance and stable machining accuracy. Self-diagnostic function, convenient and user friendly operation.
8. Automatic chip removal, tool external cooling, ATC, automatic attachment change, spindle tool internal cooling and other functional configuration are available per optional order.
