Oil country lathe 3A-47

Key Advantages of the MYDAY 3A-47 Pipe Threading Lathe

• Efficient Setup and Machining Accuracy — The pin-type tool post reduces machine setup time by up to 37%, ensuring high precision on threaded and end faces while enhancing safety during complex operations.

• Heavy-Duty Stock Removal Capability — A powerful spindle and reinforced construction enable machining of hard materials with large stock allowances, which is critical for producing components intended for intensive operational environments.

• Flexibility for Pipe Processing — Dual chuck configuration (optional) allows feeding pipes through the spindle bore, simplifying threading of long and thick-walled tubes without pre-cutting the workpiece.

• Specialization for Oil & Gas Industry — The machine is engineered to meet pipeline equipment requirements: vibration resistance, precision of threaded connections, and capability to machine corrosion-resistant materials.

• Wide Processing Range — Maximum swing over bed and center distance enable machining of large-sized components, including flanges, shafts, and pipeline elements.

• High Power and Reliability — The main drive ensures stable operation when machining hard alloys, while the cast iron bed guarantees long service life even under continuous production cycles.
