Machining Applications Across Industries
Welded steel components are essential to industrial manufacturing. Everything from construction equipment and commercial vehicles to massive infrastructure projects must be carefully fabricated to ensure safety and reliability. After welding, many components need additional machining to meet tight tolerances, ensure proper fit, and support final assembly.
At OMS Monterrey, our machining centers are designed to accommodate heavy components and extended dimensions, making them well-suited for industries such as automotive, construction, power distribution, and material handling. Large-format machining solutions are well-suited for the following:
- Semi-truck and trailer frames
- Freight and passenger rail systems
- Construction and bridge support
- Heavy-duty material handling equipment
- Renewable energy infrastructure
CNC Machining Center Advantages from OMS Monterrey
- Multi-Axis Precision Advanced multi-axis machining allows for complex geometries and tight tolerances to be achieved on uniform, irregular, or asymmetrical weldments. This is especially important for components that interface with hydraulic systems or require dynamic movement.
- Stress Relief and Surface Preparation Post-weld machining often includes surface leveling and stress relief operations. OMS Monterrey’s precision leveling and blasting capabilities complement machining by ensuring flatness and preparing surfaces for coatings or assembly.
- Quality Assurance As an ISO 9001:2015 certified facility, OMS Monterrey applies rigorous inspection protocols during and after machining. This ensures dimensional accuracy and consistency across high-volume production runs.
