CNC lathes machine complex oil equipment

Two Doosan Puma CNC lathes are machining high precision, complex components for a wide range of high integrity well completion and intervention tools and equipment.

Aberdeen, UK-based oil and gas precision component manufacturer, Omega Completion Technology is using two new Doosan Puma CNC lathes to machine high-precision, complex components for a wide-range of Omega's high integrity well completion and intervention tools and equipment.supplied by Doosan UK agent, Mills Manufacturing Technology, Leamington Spa, supplied a Puma 400L and a Puma 280L during April and June 2008 respectively.

Resources manager at Omega, Steven Smith, said that the company currently supplies over 40 different completion and intervention products to the market.

These include the following.

* Self-opening sand-face valves.

* Clean-out valves.

* Hydrostatic setting tools.

* Roller gauge carriers and more.

In addition to manufacturing and supplying be-spoke solutions to customers, Omega invests significant resources into new product development and product refinements.

Such investments have included powerful 3D modelling and animation software packages, high-performance measurement and inspection equipment and the two Puma lathes.

Smith said: "We demand a great deal from our machine tools.

The products we manufacture and supply are 'performance critical'.

That means that all the product components and parts (manufactured prior to their assembly), are 'performance critical' too".

He continued: "The new Puma lathes provide us with high-performance turning capability - accuracy, speed, reliability, flexibility and, of course, productivity".

Parts manufactured on the Puma lathes are cylindrical in shape and are made from a variety of different (and often difficult-to-machine) materials such as carbon steel, Inconel, stainless steels, and Duplex steels.

Component sizes vary: internal parts (such as for hydrostatic setting tools) are typically small and can have diameters from 1/8in to 3in.

Larger parts (capacity up to 22in diameter and up to 7ft in length) are machined from solid, often to tight tolerances (+/-50 micron), and high surface finishes.

They feature complex details including thread forms, internal and external profiles and so on.

These parts, such as the outer sections of sleeves and casings for Omega's tools and equipment like the sand face and clean out valves, are machined in small batches.

Lead times, as one would imagine in today's oil and gas sector, said Mills to manufacturingtalk, are incredibly tight and part accuracies (for reliable product performance and safety) are critically important.

* Productivity and precision - the Puma 280L machine is designed for productivity and precision, and can be relied upon to deliver both even when undertaking heavy-duty, interrupted machining.

The 280L has a powerful 22kW spindle (3,500 rev/min), 10-station turret and has 76mm bar diameter working capacity and a 10in chuck.

* Turning power - the Puma 400L is a larger and more powerful turning centre that has a a heavy-duty 26kW, 2,000 rev/min spindle to provides high metal removal rates.

The machine has a 550mm diameter turning capacity, 116.5mm bar capacity and a 15in chuck.

Both machines are equipped with FANUC control technology and have simple and easy to use conversational programming facility for quick and accurate job set-ups and data input.

In addition to the new Puma lathes Omega Completion has made previous investments in Doosan turning technology including: a Puma 300L; a Lynx 220 and another Puma 400L.

Smith said: "Our complete business focus is on providing quality products and services - and our machine tools help us achieve these objectives".

He concluded: "We pride ourselves on our 'right first time - every time' approach and our innovative solutions and ability to get them to market quickly is a major differentiator and key strength of our company".

* About Omega Completion - Omega Completion Technology is a market-leader in the design, development, manufacture, assembly and supply of completion and implementation tools the global onshore and offshore oil and gas sector.

The company's reputation and success has been built on the innovation and technical excellence of its products and services.

Over the last few years the company has experienced (consistent) double-digit sales growth, reflecting the market's demand for Omega Completion's products.
