Turning Machines for Threading Applications in the Oil and Gas Industry

Emag’s USC turning machines are designed for pipe thread applications in the oil and gas industries. The series enables facing, chamfering and thread-cutting processes to be completed on one machine. The turning machines are available in a variety of sizes for complete machining of pipes with external and internal threads, as well as proprietary threads. The machines can load and unload components in 12 to 20 sec., depending on pipe size and thread type, the company says.

A frequency-controlled AC asynchronous motor on the main drive enables simultaneous machining of both pipe ends. The pipes are clamped in front and rear chucks that can be actuated pneumatically, hydraulically or mechanically, depending on workpiece requirements. Pipe ends are stabilized during the machining process by inserting vibration-reducing mandrels for increased precision. The maximum pipe diameter ranges from 2 ³/₈" to 20", depending on the machine used.

Two compound slides with four-position, table-type turrets accommodate various tooling systems. Quick-change toolholders hold tools for internal and external turning operations. The machine base is constructed of Mineralit polymer concrete for stability and vibration resistance. Preloaded linear guideways and clamping systems provide increased rigidity and improved damping. All workholding, centering and automation equipment is configured to suit individual requirements.
