How to choose CNC lathe for oil pipeline processing? DONGS solutions is here!

The oil industry has always been regarded as one of the most demanding areas in the manufacturing industry for processing equipment. Especially in the processing of oil pipelines, joints, flanges and other parts, the equipment not only needs to have high rigidity and stability, but also must cope with the comprehensive challenges of large diameter, long size and heavy cutting. So, in the face of many machine tool brands and models, what kind of CNC lathe should be selected for oil pipeline processing? This article will analyze them one by one for you and introduce the professional solutions provided by DONGS for the industry.

1. Special requirements for oil pipeline processing

Different from general mechanical processing, oil pipeline processing has the following typical characteristics:

Large workpiece size：The diameter is usually above 800mm, and the processing length is several meters, which is difficult for ordinary machine tools to handle.

High material strength:Pipes are usually made of high-strength alloy steel or corrosion-resistant stainless steel, which places high demands on cutting force;

Strict precision requirements：The connection parts must maintain good sealing and the processing error must be strictly controlled

Long processing cycle:Stable and efficient continuous operation is required, and equipment reliability is crucial.

In summary, when choosing CNC lathes, the oil industry must give priority to the equipment's structural rigidity, stable accuracy, heavy load capacity, and automation scalability.

2. DONGS solution: born for heavy-duty processing

As an equipment manufacturer deeply engaged in the field of heavy-duty CNC lathes, DONGS CNC has launched a series of horizontal CNC turning centers designed to cope with "hard tasks" such as oil pipeline processing. The following are the core advantages of DONGS machine tools in the application of the oil field:

1. High rigidity structure design, suitable for long pipes

DONGS CNC adopts an integral casting bed and a reinforced rib structure. The bed is optimized for force through finite element analysis to effectively resist the torque and vibration generated during the processing. At the same time, the maximum processing length of more than 6000mm is capable of processing various long-axis parts such as oil casing, drill pipe, and couplings.

2. Powerful spindle system to cope with high hardness materials

The spindle adopts high-precision roller bearing configuration, combined with high-torque motor drive, to ensure that it can maintain stability and output efficiency when cutting difficult-to-process materials such as alloy steel and stainless steel. The spindle through-hole diameter can reach 230mm, which can meet the through-clamping of large-diameter pipes.

3. Efficient chip removal and lubrication system, suitable for continuous heavy-load operation

In order to meet the strict requirements of the oil industry on production efficiency, DONGS CNC lathes are equipped with high-power chip removal devices and fully automatic lubrication systems to reduce heat accumulation and wear of machine tools and ensure the reliability of long-term continuous operation.。

4. Optional power turret and Y-axis composite processing function

For some workpieces that require complex processes such as thread milling and slot processing, DONGS can provide a powered turret and Y-axis function to achieve turning and milling compound, complete multiple processes in one clamping, and improve processing efficiency and precision consistency.

3. Typical Customer Case Application

Case: A Middle Eastern customer purchased a DONGS-TCK1000 turning center for oil pipeline processing

Customer background: The customer mainly processes thick-walled casing and connectors for oil and gas companies. The traditional horizontal lathe used to be inefficient and had poor installation accuracy.

Solution: DONGS provided a customized model TCK1000, equipped with a through-hole spindle, a 12-station power turret, a servo tailstock and an automatic chip removal system.

Implementation effect:

Single-piece processing efficiency increased by more than 30%;

The machine tool has been running stably for more than 12 months without major repairs

4. Selection suggestions: How to choose suitable CNC lathes in the petroleum industry?

When purchasing CNC lathes for oil pipeline workpiece processing, it is recommended to focus on the following aspects：

The complexity and severity of the oil industry have set extremely high standards for machine tool manufacturing. DONGS horizontal CNC turning center is a high-end equipment built to meet these challenges. Whether it is heavy cutting, long-term operation, or high-precision, automated composite processing, DONGS can provide professional, efficient and reliable solutions.

If your company is looking for more powerful equipment support for oil pipeline processing, DONGS is a trustworthy partner.
