Horizontal Boring Machine
Technical Description & Specifications
Machine Overview:
The WPB130 integrates advanced structural design and manufacturing technologies with modular concepts. Utilizing modern engineering methods (FEA, virtual prototyping), this high-end CNC machine performs:
Face milling, boring, drilling, tapping
3D contour machining
Multi-process completion in single setup
Motion Axes Configuration:
X-axis: Table transverse movement
Y-axis: Spindle head vertical movement
Z-axis: Column longitudinal movement
W-axis: Spindle axial movement
B-axis: Table rotary indexing

Key Structural Features:
Frame: Optimized rib design via FEA for rigidity/stability
Guideways: X/Y/Z axes use hybrid rolling-sliding guides with PTFE coating + imported rolling elements (Low friction, high damping)
Spindle System:
Dual-layer nested spindle (Hollow milling shaft + boring shaft)
NSK bearing groups with optimized support span
Hydraulic automatic gear shifting (10-2,000 rpm)
Drive System:
FANUC AC servo motors for all axes
Planetary reducers + roller screws (X/Y/Z/W)
Anti-backlash worm gear drive (B-axis)
Rotary Table:
Double-row cylindrical roller bearings
Direct-drive dual pinion with preload
Absolute rotary encoder (Full closed-loop)

Workbench load capacity diagram and off-center load diagram

To maintain the workbench's accuracy within the specified range, workpieces should be placed within the maximum load capacity line of the workbench. If workpieces are placed beyond the load capacity line or if the center of gravity of the workpiece deviates from the center of the workbench, the load capacity and accuracy of the workbench will decrease. The load capacity is shown in the workbench load distribution diagram, and the off-center load capacity is shown in the workbench off-center load curve diagram.
