Plate Cutting

40,000W high-power laser cutting supports efficient blanking for large mining-equipment plate structures.

300–2,000 ton CNC bending and pressing equipment forms structural parts for large underground mining machines.

Dedicated assembly fixtures support accurate positioning and dimensional consistency before welding.

Automated welding is used together with positioning fixtures for stable processing of large structural components.

Critical welds undergo non-destructive testing before the structure moves to the next production stage.

Post-weld annealing reduces stress, followed by shot blasting, surface cleaning and primer application.

CNC turning, milling, boring and grinding are applied to maintain machining and assembly accuracy.

Shaft sleeves and related components use a cold-fit process to achieve an interference fit while avoiding component damage.

Component assemblies are brought together on the final assembly line to complete the machine build.
