Precision Machining for Construction Machinery & Industrial Automation Components

With over 20 years of experience in high-precision CNC machining, our factory delivers advanced solutions for critical components used in construction equipment and industrial automation systems. We specialize in producing customized mechanical parts that demand micron-level tolerances, superior wear resistance, and long-term structural reliability under harsh operating conditions.

Machining Challenges in the Industry

Construction and automation sectors require components that can withstand continuous high-load motion, abrasive environments, and complex kinematic interactions. The key challenges include:

• Achieving ±0.001 mm tolerances on components exceeding 500 mm in length.
• Maintaining concentricity and coaxiality on shafts and cylinder bores under 0.002 mm.
• Processing complex 5-axis contours for robotic joint mechanisms and actuator housings.
• Surface finish control below Ra0.2 μm for sliding or sealing interfaces.

Material Utilization for Superior Performance

To meet the industry’s mechanical and environmental demands, we work with a broad range of high-performance materials:

• 42CrMo, 34CrNiMo6: Used for high-strength transmission shafts and couplings.
• QT600 and forged steel: Applied to heavy-duty bracket systems and structural joints.
• Stainless steel (304, 316L): For corrosion-prone automation parts and hydraulic manifolds.
• PEEK and PTFE composites: For wear-resistant automation sliders, bushings, and insulators.

We use vacuum heat treatment, nitriding, and cryogenic stabilization to enhance material performance, hardness, and dimensional stability.

Process Control & Equipment Integration

Our precision is ensured by a highly integrated process flow:

• Rough machining on Mazak and Doosan turning centers.
• Milling and contouring on Mikron and DMG MORI 5-axis machining centers.
• Grinding using Studer cylindrical grinders with automatic balancing.
• Deep-hole drilling and honing for hydraulic and pneumatic components.

Quality assurance is embedded in every step with in-house measurement tools:

• ZEISS CMMs with scanning probes.
• Mitutoyo roundness testers for shaft and bore integrity.
• Hommel surface profilometers to monitor surface roughness.
