Used DOCHI CS6150B Large Hole Horizontal Lathe For Sale

A Large Hole Horizontal Lathe is a specialized type of lathe designed for machining large and heavy workpieces with large-diameter holes. These machines are commonly used in industries such as oil and gas, energy, heavy machinery, and aerospace, where components with large boreholes need to be machined accurately.

Here’s a detailed description of the features and components you might find in a Large Hole Horizontal Lathe:

1. Sturdy Base and Frame: A Large Hole Horizontal Lathe,The lathe’s base and frame are constructed to handle the weight and size of large workpieces, ensuring stability and minimizing vibrations during machining.
2. Headstock and Tailstock: The headstock houses the spindle, which rotates the workpiece, while the tailstock supports the other end of the workpiece. In large hole lathes, the tailstock may have a larger quill diameter to accommodate large-diameter workpieces.
3. Workholding Mechanism:  Large hole lathes are equipped with chucks or special fixtures designed to securely hold and rotate the large workpiece.
4. Axis Movement:  A Large Hole Horizontal Lathe,A typical large hole lathe may have several axes of movement:
   • Z-Axis: Controls the longitudinal movement of the tool along the length of the workpiece.
   • X-Axis: Controls the cross-slide movement for facing and other lateral operations.
   • Bore Axis (W-Axis): In large hole lathes, this axis controls the movement of the boring tool into and out of the hole.
5. Boring Bar Attachment: Large hole lathes are equipped with specialized boring bars designed to accurately machine large-diameter holes to specific depths and tolerances.
6. Boring Tool Holders: These holders secure the boring bars and allow for precise adjustment and positioning.
7. CNC Control System: Many modern large hole lathes feature a computer numerical control (CNC) system for accurate and automated machining. The CNC system allows for precise control of the axes, feed rates, and depths of cut.
8. Coolant System: A coolant system is crucial for maintaining proper cutting conditions, dissipating heat, and evacuating chips and debris from the machining area.
9. Enclosure: An enclosure contains coolant, chips, and noise, enhancing operator safety and maintaining a clean working environment.
10. Safety Features: Lathes are equipped with safety measures such as emergency stops, interlocks, and safety guards to protect operators during operation.
11. Measuring and Inspection: Some large hole lathes have measuring and inspection systems to verify the accuracy of machined features, ensuring that large-diameter holes meet required specifications.
