| Material | 6061-T6 aluminum alloy – prone to deformation during deep cavity machining | Material stabilized through stress relief and aging heat treatment before machining | Reduced deformation |
| Wall Thickness | 2.0 mm, uneven wall thickness leading to rigidity issue | Optimized wall structure and machining sequence for better clamping and support | Improved stability |
| Machining Process | Multiple milling operations + manual finishing | Optimized 5-axis CNC strategy and toolpath | 30% cycle time reduction |
| Tolerance | Flatness ±0.05 mm, hole diameter ±0.03 mm | Flatness ±0.01 mm, hole diameter ±0.01 mm | Tighter tolerance control |
| Surface Finish | Ra 1.6 μm with hard anodizing | Ra 0.4 μm with Nikasil coating | Better wear and heat resistance with improved sealing and smoother finish |
| Cost Efficiency | Frequent rework, high material waste | Streamlined process reduced cost by 22% | Lower production cost |
Through early DFM analysis, Taidexingrefined the cylinder block’s structure, machining approach, and surface treatment — achieving higher precision, smoother finishes, and more durable surfaces.

CNC Machining Surface Finishing Options
Taidexing offers surface finishing to enhance appearance, durability, and performance of CNC machined parts — meeting functional and aesthetic needs across industries.
| Surface Finish Option | Process Description | Typical Applications / Benefits |
| Hard Chrome Plating | A plating process that deposits an ultra-hard chromium layer on the part surface, delivering exceptional surface hardness and wear resistance. | Ideal for hydraulic components, gears, shafts and cutting tools; widely used in automotive and industrial machinery requiring long-lasting abrasion protection. |
| Electroless Nickel Plating | A chemical plating process that deposits a uniform nickel layer without external current, with consistent coating thickness even on complex geometric surfaces. | Provides excellent corrosion resistance and hardness, perfect for precision electronic parts, aerospace components and medical devices with strict tolerance requirements. |
| Anodizing | An electrochemical process that forms a dense protective oxide layer on aluminum surfaces, enhancing surface hardness and corrosion resistance. | Common in consumer electronics, automotive parts and structural components for improved durability and versatile aesthetic options. |
| Black Anodizing | A specialized anodizing process that creates a uniform matte black oxide layer on aluminum, combining corrosion resistance with a non-reflective finish. | Used in optical components, electronic enclosures, military parts and industrial equipment where light reflection reduction and consistent appearance are required. |
| Hard Anodizing | A high-density anodizing process that forms a thick, ceramic-grade oxide layer on aluminum, delivering 2-3 times higher hardness than standard anodizing. | Ideal for high-wear parts including hydraulic cylinders, pistons, gears and aerospace components; provides superior abrasion and scratch resistance. |
| Oxide Sandblasting | A combined process of sandblasting to create a uniform matte texture, followed by oxide passivation to enhance corrosion resistance and coating adhesion. | Produces a consistent non-reflective surface, perfect for automotive interiors, aerospace parts and components requiring reliable paint adhesion and visual uniformity. |
| Zinc Plating | A galvanizing process that deposits a zinc layer on steel surfaces, providing sacrificial cathodic protection against rust and corrosion. | Cost-effective corrosion protection for fasteners, brackets, structural steel parts and automotive components; widely used in construction and general industrial applications. |
| Silver Plating | A plating process that deposits a high-purity silver layer on the part surface, offering excellent electrical conductivity, thermal conductivity and tarnish resistance. | Used in electrical connectors, switch contacts, RF components and high-precision electronic parts requiring superior conductivity and low contact resistance. |

Design Challenge
The original design contained ultra-thin walls, deep narrow cavities and inconsistent fillet radii. The initial structure risked deformation, vibration during machining, low yield and long processing cycle.
Our DFM Optimization
Taidexing engineers conducted complete DFM review. We adjusted wall thickness, added transitional fillets, optimized clamping scheme and revised toolpath strategy before machining. Material stress relief was arranged to minimize distortion.
Optimization Result
Machining deformation greatly reduced; production cycle shortened by 28%. Dimensional tolerance stabilized within ±0.005mm, scrap rate effectively controlled.
