A domestic aerospace components manufacturer—the VL1165 vertical machining center—has overcome the challenges in machining high-temperature alloy turbine blades.

Release time:

2025-11-21

The company specializes in the R&D and manufacturing of core components for aerospace engines, providing high-precision parts such as turbine blades and combustion chambers to domestic defense industry enterprises. Previously, when machining Inconel 718 high-temperature alloy turbine blades, the company faced challenges including rapid tool wear, significant part deformation, and low machining efficiency—issues that made it impossible to meet the stringent standards required for defense products.

Customer Background

Customer needs

1. Machining Inconel 718 high-temperature alloy turbine blades (thickness: 3–5 mm), with dimensional tolerances ≤ ±0.004 mm and part deformation ≤ 0.002 mm.

2. Tool life must be extended by more than 30% to reduce consumable costs;

3. The equipment must have data traceability capabilities for processing and comply with the requirements of the AS9100 aerospace quality management system.

Dike Solutions

Offer an exclusive solution: “VL1165 Vertical Machining Center + Customized Process Package.”

1. Equipment Selection: The VL1165 vertical machining center features an integral cast-iron gantry structure and a 22-kW high-power spindle (maximum torque of 280 N·m), paired with a constant-temperature cooling system and a grating-scale closed-loop control system.

2. Process Customization: Based on the characteristics of Inconel 718, we recommend carbide tools with WC-Co coatings and optimized cutting parameters (cutting speed: 100 m/min; feed rate: 0.15 mm/r). A dual protection system—combining “mist lubrication + high-pressure cooling”—is employed to minimize tool adhesion and wear.

3. Data Traceability: Equipped with a processing data traceability system, it records in real time key data such as spindle speed, cutting temperature, and machining time, and automatically generates exportable reports to meet the traceability requirements of the AS9100 standard.

Implementation effect

1. Precision and Quality: The dimensional error of the turbine blades is controlled within ±0.003 mm, and the part deformation is ≤0.002 mm, fully meeting military standards and passing customer acceptance on the first attempt.

2. Tool life: The tool service life has been extended from the original 80 pieces per tool to 115 pieces per tool, an increase of 44%. This results in annual savings of approximately RMB 200,000 in tool costs.

3. Compliance: Processed data can be traced in real time, ensuring smooth passage of the AS9100 system audit and laying a solid foundation for the company to secure defense industry contracts.
