Big and precise: Why DONGS medium and large horizontal turning centers have become the new focus of the manufacturing industry

Jun.20.2025

In the tide of transformation and upgrading of the manufacturing industry, "large and precise" has become a new requirement for equipment put forward by more and more companies. Especially in the fields of petroleum energy, wind power equipment, shipbuilding engineering, heavy machinery, etc., the processing scenes of medium and large complex parts continue to emerge, bringing new challenges to traditional CNC machine tools: not only must they be able to process "large" workpieces, but they must also achieve the comprehensive performance of "high precision", "high efficiency" and "high reliability".

Facing this trend, Shandong Dongshi CNC Equipment Co., Ltd. (DONGS CNC) has focused on the market segment of medium and large horizontal turning centers. With its solid manufacturing foundation and in-depth understanding of user processes, it has quickly stood out in the market and become the "new focus" of manufacturing companies.

一、The demand for large workpiece processing is increasing, and traditional machine tools are gradually unable to cope with it

With the acceleration of large-scale equipment and industrial upgrading, the processing of medium and large parts is no longer limited to the "machining" of a single dimension, but is moving towards one-time molding, high precision, fast beat, strong stability.

For example:

 

Oil casing and drill pipe,Large pipe diameter, long length, large variation in wall thickness;

Wind turbine main shaft or bearing seat,High precision requirements and extremely small dimensional deviations;

Large flange and connecting ring,It requires composite processing and end face processing to be completed in one piece.

 

When faced with these processing requirements, traditional general-purpose horizontal lathes often have low efficiency and unstable precision due to insufficient rigidity, limited travel or single function, which seriously restricts production capacity and delivery quality.

二、DONGS solution: born for "big and complex"

At the beginning of design, DONGS medium and large horizontal turning centers took "heavy-load cutting + one-time clamping + multi-process integration" as the core goal, and carried out in-depth optimization from the three dimensions of structure, control, and configuration to truly serve the core demand of "machining large and precise"

1. High rigidity structure design

The whole machine adopts a high-strength cast iron integrated bed structure, and the base and guide rails are widened and thickened, which effectively suppresses the resonance and deformation generated during the processing of large workpieces and provides solid support for heavy-load cutting.

2. Extra large through-hole spindle and powerful drive system

The spindle aperture can reach more than 300mm, which is suitable for smooth material flow of large-diameter pipes and large-diameter workpieces. With a high-torque servo motor, it can achieve low-speed high-load and heavy cutting without breaking the knife, and even thick-walled blanks can be steadily taken down.

3. Multifunctional composite processing module

It supports the installation of a power turret, end drive module, and automatic tool changing system, enabling the completion of multiple processes such as turning, drilling, tapping, and chamfering in one clamping, effectively shortening the production cycle and improving the yield rate.

4. Digital operating system and intelligent assistance

Equipped with a user-friendly CNC interface (supporting Fanuc, Siemens, Synage, etc.), it has functions such as machining program prediction, spindle load monitoring, and tool life management, making "high-end machining" more "simple and easy to control".

三、Customer verification: large size ≠ high risk, large processing can also be efficient

A European engineering machinery manufacturing company needs to batch process hydraulic transmission shafts with a length of 3.5 meters and a diameter of 800 mm. Before using the DONGS horizontal turning center, the company used two independent processes of "rough turning-transfer-finishing turning", and the processing cycle of a single piece exceeded 8 hours.

After the introduction of DONGS equipment, the whole set of roughing and finishing processes can be completed through one clamping, the processing cycle is shortened to 4 hours, the dimensional stability is improved, and there is no need to correct the assembly dimensions again after processing. The person in charge of the company commented: "In the past, we thought that large-scale processing could only rely on 'slow work and fine work', but now we see that 'fast and steady' is the real manufacturing power."

四、Why is DONGS the focus? Because it is not only "big", but also "exquisite"

The future of manufacturing industry does not rely on piling up equipment and manpower, but on the refined improvement of system capabilities. The reason why DONGS is chosen by more and more companies is not only because its machine tools are large, heavy and hard enough, but also because it considers the actual usage scenarios of customers from the entire chain of design, manufacturing and service.

For the pipe industry: can be equipped with pipe cooling system and mandrel support;

For shaft processing: support multi-point stable support and online concentricity monitoring;

For flange workpieces: it has the ability to perform high-precision end face composite processing.

 

These invisible detailsare the key to helping customers achieve high qualityon large workpieces.

 

"Making it big" is not difficult, "making it fine" is the real skill. Today, when large-scale processing is becoming more and more common, DONGS redefines the role of medium and large horizontal turning centers in modern manufacturing with the product concept of "big and fine". It is not just a tool, but also a key for enterprises to move towards efficient intelligent manufacturing.

When the market is calling for "intelligentization of heavy equipment", DONGS is already on the road.
