1. Forging Foundation: Strengthening Large-Scale Component Manufacturing

• Technical Advantages: Adopts "step-type isothermal forging" and "integral forging-segmented quenching" processes. The hardness variation of 11-meter guideways is ≤ HRC ± 2, and the deformation resistance is 35% higher than that of traditional processes.

• Capacity & Equipment: Equipped with 2,000-ton hydraulic die forging hammers and other equipment, capable of producing forgings weighing 0.5-50 tons. Annual capacity reaches 8,000 tons, with a qualification rate of key forgings ≥ 99.2%, realizing independent supply of large-scale forgings.

2. Processing Breakthrough: Full-Process Precision Control

1. Rough Machining: Efficient Shaping

• For cast iron machine beds: Uses "layered milling + water spray cooling" with a daily processing volume of 15 m³ and an error of ± 0.5 mm; for alloy steel spindle boxes: Applies "high-speed milling + vibration aging" to eliminate internal stress.

• Gear Branch: Has 217 sets of equipment, including 34 gear grinding machines for rough machining up to DIN3961-3 standard, with an annual output of 4 million gear forgings.

2. Precision Machining: Micron-Level Breakthrough

• 11-meter CNC guideway grinding machine + on-line inspection: The straightness error of guideways is ≤ 0.008 mm/m; radial runout of 8,000 rpm spindles is ≤ 0.002 mm.

• Self-developed 5-axis machining centers: Achieve ± 0.005 mm precision for complex curved surface machining; 70% of equipment is localized. The GMC series has 15% higher efficiency and 30% lower cost than imported equipment.

3. Precision Testing: Comprehensive Strict Inspection

1. Component-Level Testing

• Guideways: Inspected every 0.5 meters with laser interferometers; spindles: Underwent 24-hour continuous operation testing; Nano-grating displacement sensors: Realize 0.01 μm measurement, with better anti-interference performance than traditional gratings.

2. Machine-Level Testing

• 5-axis machines must pass the "S-test piece" international standard, with 200-point scanning; rework is required if the profile error exceeds 0.015 mm. The 7-meter gantry machining center launched in 2023 has a positioning accuracy of ± 0.01 mm, becoming a core equipment for "machine tool mother machines".

4. Equipment Commissioning: Customized Empowerment

• System Efficiency: Three-level commissioning ("basic-process-capacity") reduces the cycle by 20% compared with the industry average; equipped with portable laser interferometers and other tools to complete on-site precision compensation.

• Case Achievements: On-site commissioning for Jiangsu Pin'er's equipment increased efficiency by 30%; 72-hour full-load testing of 5-axis equipment further improved precision by 25% after parameter optimization.

5.Strong Customization Capability

1. Rapid Response: 72-Hour Demand Closure Loop

• Respond to demands within 24 hours and break down core indicators in 3 hours;

• Deliver initial solutions in 72 hours and optimize solutions in 48 hours, cutting the cycle by 50%.

2. Technical Adaptation: Full-Chain In-Depth Customization

• Core components: Can increase spindle torque by 1.8x and extend guideways to 15 meters;

• Process packages: Provide supporting dedicated fixtures and parameter databases, eliminating secondary debugging;

• Software: Add new functional modules, achieving a precision of ±0.003mm.

3. Industry Application: Results in Key Scenarios

• New Energy: Custom 5-axis machines with 8-ton workbench load capacity, 40% higher efficiency, and 2.5% lower defect rate;

• Aerospace: 7-meter gantry machines, enabling one-time forming of rocket components with 100% precision;

• Heavy Equipment: Boring and milling machines with 300mm spindle bore, 60% higher single-shift capacity.
