Oil Field Technology and Vehicular Hydraulics USC 21 USC 27

The USC 21 machine series for tube end machining and the USC 27 center drive lathe for the machining of couplings and tool joints offer customized solutions for the machining of all types of thread. In fact, these state-of-the art machine tools are capable of machining all the threads on OCTG components, whether they are international (API, GOST) or a proprietary threads.

The USC series' most distinctive feature is its rigid machine construction. All machine modules are very stable, right down to the MINERALIT® polymer concrete machine base. External as well as all internal machining operations can be carried out on a single machine. This machine concept is designed for the complete-machining of all popular threads, API and GOST standard and of all proprietary threads, including integral joints. The main drive of the tube machining center is an important part of the spindle unit and guarantees high power and torque ratings. The direct drive consists of a...

The high-precision machining equipment includes two of the newest generation flat-bed turrets, each travelling on their own compound slide. Each turret features 4 tool stations that can be equipped with a variety of tooling systems. The change holders in the turret accommodate external and internal turning tools. The vertical design of the machine base and a generously dimensioned chip conveyor guarantee unobstructed chip flow. • The tubes external or internal diameters are aligned using a centering attachment. • During machining, the inside of the tube is sealed against the opening...

Nominal diameter

The concept of the USC 21 is designed for the machining of pipe ends. It combines all the features that are responsible for quality, durability and productivity, with flexibility that covers all the applications for standard and premium threads. With the choice of 5 spindle sizes all pipe diameter ranging from 2 %" to 20" can be machined with the best technological and customized conditions. The USC 21 series is modular and can be executed as 2-axis-, 4-axis and 6-axis-machine concept. Separate axes accommodate the unit for external and internal centering, the tube stop, and the setting...

The center drive machine, USC 27 stands for efficiency. It impresses with its capability to simultaneously complete machine both sides of coupling sleeves and tool joints with international threads like API and GOST or threads of proprietary standard. The USC 27's machine base is made with the high-quality MINERALIT® polymer concrete, a material that has an outstanding damping quality. The EMAG four-station flat-bed turrets are mounted on the cross slides to the right and left of the center drive headstock. The rapid traverse speeds of the cross slides and the automatic workhandling system...

With the USC 21 and USC 27 EMAG offers complete systems for the manufacture of couplings: • Turnkey solutions, i.e. all technology, automation and production processes from a single source • Centralized project management: Only one contact for the customer • Faster start-up through optimized interfacing • Maintenance-friendly, with the same components used on all machines • Optimized overall process, where manufacturing systems and peripherals are an optimal match The advantage over systems that include sawing machines is the amount of money you save on saw blades. With EMAG production...

This leads to a saving in throughput time of 30 – 50%, depending on the type of coupling, the thread contour and the material. Machining of couplings with a nominal diameter of 5 1⁄₅“ to 13 ⅜“ on a USC 21 and a U

Components for vehicular hydraulics made on USC machines. The USC 21 concept is ideal for this machining. Everything can be done with minimal setting efforts and with the best quality and productivity levels. The flexible workhandling equipment is designed to order and can be fully automated. Transport and machine systems adapt themselves to the various workpiece dimensions without having to be reset.

EMAG can look back on the many years of experience in the machining of oil field components (Oil Country Tubular Goods - OCTG). Nowadays, production plants (finishing lines) for the machining of tubes, couplings, tool joints and caps cover a multitude of manufacturing processes. Besides CNC threading machines the machinery includes automatic mandrel testing stations, magnetic crack detectors, coupling assembly lines, thread protection and nipple assembly points, automatic test presses, coating plants, length meters, weighing stations, embossing stations, band markers, tube bundling...
