Step 1: Material Selection

The correct steel grade is selected according to:

• Strength requirements
• Corrosion resistance
• Heat resistance
• Machinability
• Cost considerations

Step 2: CNC Programming

Engineers create detailed CNC programs that define:

• Dimensions
• Cutting paths
• Tool movement
• Machining speed
• Tolerance limits

Step 3: Precision Turning

The steel workpiece rotates while cutting tools remove material precisely.

Step 4: Secondary Operations

Additional processes may include:

• Drilling
• Threading
• Milling
• Grinding
• Knurling

Step 5: Surface Treatment

Surface finishing improves durability and appearance.

Step 6: Inspection

Finished parts undergo strict quality checks before shipment.

5. What Types of Steel Are Commonly Used?

Different steel materials offer unique properties for various applications.
