Product Description

Horizontal deep hole drilling machine for shaft
Model# SD-400
The shaft hole drilling machine is a specialized industrial equipment designed for precision drilling of axial holes in shafts, cylindrical components, or rotational workpieces. It is widely used in mechanical manufacturing, automotive, aerospace, and heavy machinery industries for creating accurate through-holes or blind holes in shafts to accommodate pins, keys, lubrication channels, or assembly connections.
- Heavy-duty base and column to ensure stability during high-precision operations.  
- Rigid spindle system for minimizing vibration and maintaining drilling accuracy.
- High-speed rotating drill head with variable RPM settings for different materials (steel, alloy, composites).  
- Automatic feed system with programmable depth control for consistent hole dimensions

Applications:  
- Drilling oil passages in engine crankshafts  
- Creating keyways in power transmission shafts  
- Precision hole patterns in hydraulic cylinder rods  
- Maintenance/repair of industrial rotating equipment
