The manufacturing of mining machinery is a complex process that encompasses design, material processing, assembly, and testing. Below is a comprehensive introduction to the entire manufacturing process, integrating key technologies such as sheet metal processing, welding, and machining:
1. Requirement Analysis and Design Phase
2. Raw Material Preparation and Pre-treatment
3. Core Manufacturing Process
Sheet Metal Processing: Material cutting → Forming → Joining
Heavy Structural Welding: Welding process selection (welding method); Quality control (pre-welding and post-welding preparations).
Machining: Machine tool processing (turning and milling); Special processes (heat treatment and surface hardening).
Assembly and Final Assembly: Sub-assembly; Final assembly and debugging.
Surface Treatment and Coating
Quality Inspection and Testing

Common Issues and Solutions in Mining Machinery Fabrication:
Excessive burrs on material cutting edges
Optimize cutting parameters (reduce laser power, increase cutting speed).
Cracking or excessive springback after sheet metal bending
Adjust the bending radius (typically ≥1.5 times the sheet thickness); Orient the bending direction perpendicular to the material grain direction (avoid bending along the rolling direction); Implement bending compensation.
Welding distortion causing assembly misalignment
Use segmented welding to reduce localized heat accumulation; Employ welding fixtures to secure the workpiece; Perform mechanical straightening after welding.
Coating peeling or bubbling after painting
Perform sandblasting before painting; Control the painting environment; Use epoxy zinc-rich primer to enhance adhesion.
Excessive flatness deviation in large sheet metal components
Apply vibration stress relief after welding to eliminate residual stresses; Store large flat components vertically to prevent deformation due to self-weight.
