Overview
Precision metal fabrication performs metal shaping and finishing using high-accuracy methods to meet strict dimensional, geometric and surface requirements for components used in demanding industrial applications.

Key features

• High-precision equipment: CNC machining centers, multi-axis machines, EDM and laser cutting to ensure positioning accuracy, repeatability and surface integrity.
• Material selection: Use of stainless steel, alloy steels, copper, aluminium, titanium alloys and cemented carbides chosen for mechanical and thermal properties.
• Advanced processes: Precision casting, forging, stamping, laser cutting, numerical-control machining, metal 3D printing and MIM selected according to part geometry and tolerances.
• Strict quality control: Incoming material inspection, in-process monitoring and final verification using CMM, surface roughness testers and other metrology tools.

Typical process steps

• Blank preparation: Select and prepare raw blanks to meet final dimensions and material specifications.
• Fixture design and fabrication: Develop fixtures and jigs for secure, repeatable part positioning.
• Machine setup: Configure machine tools for required precision and rigidity.
• Tool selection: Choose cutting tools and inserts matched to material and process demands.
• Parameter programming: Define cutting speeds, feeds, depths, coolant and other machining parameters.
• CAM toolpath planning: Generate and validate toolpaths to meet geometric and surface requirements.
• Machining: Execute material removal or forming operations to achieve final geometry.
• Inspection: Control critical dimensions and tolerances at designated checkpoints.
• Post-treatment: Deburring, heat treatments, surface finishing and other required secondary operations.
