Step-by-Step Machining and Fabrication Process
Design Interpretation and Material Selection
The fabrication process starts with a thorough review of engineering drawings or 3D CAD models that clearly define all technical specifications—such as tolerances, surface finish requirements, geometry, and assembly fit.
- Our experienced engineers analyze these designs to understand the functional and structural demands of the final product.
- Based on this analysis, the most suitable raw materials—whether steel, cast iron, or specialized alloys—are selected, taking into account factors like wear resistance, mechanical strength, and environmental conditions the component will face.
- This careful selection ensures the fabricated part meets both performance expectations and longevity requirements.
Cutting, Shaping, and Machining
Once materials are selected, precision machining begins to transform raw stock into accurately shaped components:
- We use a combination of CNC (Computer Numerical Control) and conventional machine tools to execute cutting, turning, milling, drilling, boring, and grinding operations.
- Each machining process is performed under strict quality controls, maintaining tight tolerances and ensuring high repeatability for consistent production.
- This meticulous shaping ensures components precisely match design specifications, facilitating easier assembly and optimal functionality.
Welding and Assembly
For parts requiring fabrication, advanced welding techniques and precise assembly procedures are employed:
- Skilled, certified welders use MIG, TIG, and arc welding methods to join components with strong, durable welds.
- Specialized jigs and fixtures are utilized to maintain correct alignment and positioning during the welding process, preventing distortion and ensuring structural integrity.
- After welding, assemblies undergo further machining and finishing processes to fine-tune dimensions, achieve smooth surfaces, and prepare the components for final assembly or delivery.
