- Machining Workflows
Our CNC Milling Process
Advanced CNC milling ensures micron-level precision for critical electronic components used in renewable energy control systems.
Engineers design the part using CAD (Computer-Aided Design) software. The design includes all dimensions and specifications.
The CAD design is converted into CNC code, often using CAM (Computer-Aided Manufacturing) software. This code tells the milling machine how to move and cut the material.
Operators prepare the CNC milling machine by securing the material (workpiece) and installing the appropriate cutting tools.
The CNC machine reads the code and starts milling. The cutting tool rotates and moves along multiple axes to remove material from the workpiece and shape it into the desired part.
The machine monitors the cutting operations throughout the process. Operators may make adjustments to ensure precision and quality.
After milling, the part may undergo additional processes like deburring or polishing to achieve the final specifications.
The finished part is thoroughly inspected to meet all design requirements and tolerances.
