Construction Machinery

What are some characteristics and challenges of the construction machinery manufacturing and processing industry?

Characteristics:

• Large workpieces are common. Typical construction machinery parts such as chassis brackets, connecting rods, housings, and support arms are large in size and heavy in weight, which places higher demands on the rigidity, travel, and clamping capacity of machining equipment.

• High-hardness and wear-resistant materials are widely used, including high-strength alloy steels and wear-resistant cast iron.

• Precision and functionality are equally important. Although the parts are large, key areas must still meet strict assembly accuracy and functional requirements to ensure the stability and safety of the entire machine.

• There is a strong demand for small-batch customized production. Different customers and machine models often have personalized requirements for component structures, interfaces, and performance, so the machining process must offer flexibility and quick responsiveness.

Challenges:

• Welded structures or parts that have undergone heat treatment are especially prone to deformation. We effectively control the final dimensional accuracy by optimizing machining paths and applying intermediate stress-relief treatments.

• Many components feature irregular curved surfaces, multi-face positioning, or deep cavities. Our facility is equipped with five-face gantry machining centers and horizontal machining centers, enabling multi-surface machining in a single setup to enhance both efficiency and precision.

• Surfaces involved in sealing, sliding, or connecting require high surface quality and geometric accuracy. We provide high-precision grinding, polishing, and surface strengthening services to meet these demands.

• High-strength materials cause rapid tool wear. By selecting high-performance tooling and optimizing feed rates and cutting depths, we extend tool life and ensure machining stability.

• While meeting high quality standards, we help customers achieve an optimal balance between efficiency and cost through lean manufacturing, automated process integration, and professional fixture design.
