Summary

The SMTCL STC34300 is a CNC oil country pipe threading lathe engineered for precision external and internal threading of large-diameter pipes, particularly for petroleum and related heavy industries. Its design supports the machining of cylindrical and conical threads to metric and British standards, as well as general shaft and disc turning operations. The integration of a FANUC control system, high machining accuracy (IT6-IT7), and a large spindle bore enables reliable production of oilfield components such as drill pipes and casing pipes.

Key Capabilities

• CNC-controlled pipe threading for cylindrical and conical threads (metric and British system)
• Accommodates large-diameter tubular workpieces up to 13 3/8" OD
• Supports additional turning operations on shafts and disc components of varied geometries
• Vertical 4-position tool turret for automated tool changes
• Suitable for machining oil products including drill pipes, drill collars, casing pipes, and petroleum casing pipes
• FANUC system for precise control and repeatability
