Design

The High-Rigidity 12-Station CNC Lathe integrates functional design with durability to optimize machining performance. Its structure is engineered to support heavy loads and minimize vibration, ensuring stability during high-speed operations. The inclusion of a 12-station turret enhances tool-changing efficiency, reducing downtime between operations and boosting overall productivity.

The X and Z axes are designed for smooth, precise movement, with rapid traverse speeds of 18 m/min (X-axis) and 15 m/min (Z-axis) to shorten non-cutting time. The tailstock, with a quill travel of 120 mm and MT-6 taper, provides secure support for long workpieces, preventing deflection and maintaining machining accuracy.

With a compact floor footprint of 3400×1900 mm and a total weight of 6000 kg, the lathe balances stability with space efficiency, making it suitable for various workshop layouts. Optional configurations further allow customization to adapt to specific production requirements, ensuring versatility across different machining scenarios.

This design focus on rigidity, precision, and adaptability positions the lathe as a top choice for manufacturers seeking to streamline large-part machining processes while maintaining consistent quality.

1. Precision machining of complex components

Structural component machining: Large structural components such as the chassis, boom, and slewing bearings of construction machinery typically require high-strength steel and have complex shapes. CNC machine tools can achieve high-precision machining of complex curved surfaces and irregular hole positions, ensuring the load-bearing capacity and assembly accuracy of structural components.

Transmission system components: Critical transmission components such as gears, bearing housings, and gearbox casings have extremely stringent requirements for tolerances and surface finish. CNC machine tools can achieve micron-level precision machining, ensuring transmission efficiency and reliability.

Hydraulic component manufacturing: Precision hydraulic components such as hydraulic valve bodies and pump housings require strict internal flow channel machining and sealing surface treatment. Through multi-axis interpolation and the use of small tools, complex internal cavities can be machined to eliminate leakage risks.

2. Mass production and quality stability

Large-scale production: The construction machinery industry has a high demand for mass-produced parts (such as pins, connecting rods, and flanges). CNC machine tools achieve continuous processing through programmed control, significantly improving efficiency (e.g., CNC lathes can process dozens of parts per hour).

Consistency assurance: Digital programmes eliminate human error, ensuring dimensional consistency among parts in the same batch and reducing assembly debugging costs.

3. Addressing the Challenges of Processing High-Strength Materials

Construction machinery commonly uses high-strength steel, wear-resistant cast iron, and alloy materials, which can cause tool wear or deformation when processed by traditional machine tools.

CNC machine tools use adaptive cutting parameters (such as optimised speed and feed rate) and advanced tooling technology (such as coated tools and ceramic tools) to efficiently process difficult-to-machine materials and extend tool life.

What material is used for the machine tool bed?

Machine tool casting using HT300.

Is customization available?

Yes. We have rich experience in custom processing and can provide flexible customization services from bed to processing parameters to appearance.

What is your company's after-sales service support?

1). Supply wearing parts, spare parts and spare parts at the cost price (outside the warranty period);

2). Party B provides Party A with consulting services on processing technology and programming;

3). After the expiration of the warranty period, Party B still provides after-sales service;
