1. CNC Turning Machining and Precision Enhancement

CNC turning machining enables precise shaping of automotive components with tight tolerances:

• High Repeatability: Automated CNC processes ensure consistent dimensional accuracy across large production runs.

• Complex Geometries: CNC lathes can handle intricate contours, threads, and grooves that manual machining cannot achieve consistently.

• Micron-Level Tolerance: Advanced CNC machines in Tiger Casting maintain tolerances to ±0.01 mm, critical for engine, transmission, and braking components.

• Surface Finish Quality: Polishing, shot blasting, and precise feed control provide superior surface finishes, reducing friction and enhancing performance in automotive assemblies.

Precision machining reduces assembly errors, improves part longevity, and ensures compatibility with other tightly engineered components.

2. Waste Reduction Through CNC Machining

Material efficiency is crucial in automotive production. CNC turning minimizes waste through:

• Optimized Tool Paths: CNC software calculates precise cutting sequences to minimize scrap.

• Reduced Human Error: Automation eliminates operator inconsistencies that can lead to defective or wasted parts.

• Repeatable Setup: Once programmed, CNC lathes reproduce parts with consistent material usage across multiple batches.

• Scrap Recovery: Aluminum chips and offcuts can often be recycled, further reducing net material waste.

By controlling material removal precisely, Tiger Casting achieves both environmental and economic benefits in high-volume automotive manufacturing.

5. Quality Control and Precision Verification

Maintaining precision requires robust quality control at every stage:

• Dimensional Verification: CNC parts are checked using micrometers, coordinate measuring machines (CMM), and measuring projectors.

• Material Analysis: Spectrometers verify aluminum alloy composition for strength and corrosion resistance.

• Mechanical Testing: Tensile and hardness testing confirm structural integrity.

• Non-Destructive Testing: X-ray detection ensures no internal defects in cast or machined parts.

By integrating inspection with CNC production, Tiger Casting minimizes defective parts and ensures that each component meets global quality expectations.

7. Cost Efficiency Through Precision and Waste Minimization

Precision and waste reduction contribute directly to cost efficiency:

• Material Savings: Reduced scrap and optimized cutting paths lower raw material consumption.

• Labor Savings: CNC automation reduces manual machining requirements.

• Reduced Rework: Fewer defective parts decrease downtime and repair costs.

• Energy Efficiency: Optimized machine operation consumes less electricity per part, reducing operational expenses.

High-precision CNC turning provides a return on investment by balancing quality, speed, and material utilization.
