High-End Lightweight Titanium Alloy CNC Solutions - Custom Parts for Racing Cars, Golf Heads, and High-End Consumer Products

Customized Parts
I. Core Service Advantages
1. Perfect Balance of Lightweight and High Strength
We specialize in processing high-end titanium alloys such as TC4 (Ti-6Al-4V), TC11, and GR5. These materials boast a density of only 4.5g/cm³ (approximately half that of steel) but a tensile strength of 860-1100MPa, resulting in a strength-to-weight ratio far exceeding that of aluminum alloys and stainless steel. Through integrated CNC precision milling/turning, we reduce part weight by 30%-50% while increasing structural strength by 20%-40%. This perfectly meets the core requirements of "weight reduction and speed improvement" for racing cars, "precise weight balance" for golf heads, and "lightweight and premium" for high-end consumer products.
2. Precision Customization of Complex Structures, Breaking Through Process Bottlenecks
For special-shaped parts in three major application areas (such as hollowed-out racing chassis frames, complex curved surfaces in golf heads, and irregular accessories for luxury goods), we utilize five-axis CNC machining with positioning accuracy of ±0.002mm and repeatability of ±0.001mm. This system supports machining complex features such as thin walls (down to 0.8mm), deep cavities (aspect ratio of 10:1), and irregularly shaped holes. Surface profile tolerances are ≤±0.003mm, and surface finishes are Ra ≤0.4μm, ensuring the reproduction of design details.
3. Exclusive Titanium Alloy Processing Technology Ensures Stable Quality
To address the processing challenges of titanium alloys due to their low thermal conductivity and prone to tool sticking, three core processes have been customized:
- Low-Temperature Cutting Technology: Equipped with a -15°C cold air cooling system, this reduces thermal stress during machining and prevents warping in thin-walled parts;
- High-Pressure Internal Cooling: Cooling pressures reach 100 bar, rapidly removing chips and preventing tool wear (extending tool life by 35%);
- Aging Treatment: Post-processing, a 500-600°C vacuum aging treatment enhances the fatigue strength of titanium alloy parts, achieving a fatigue life of over 100,000 cycles for racing parts.
4. Full-Scenario Customization and Leading Delivery Efficiency
Supporting both small-batch customization (1-20 pieces) and medium-batch production (50-500 pieces), we can rapidly respond to requests for racing car parts, golf head prototypes, and limited-edition high-end consumer goods, including 2D drawings and 3D models (in STEP/IGS/X_T formats), with a process and disassembly cycle time reduced to 24 hours. Equipped with three five-axis machining centers for parallel production, regular order delivery is 7-12 days, while urgent racing parts orders can be delivered within 48 hours.

- Fixtures: Customized vacuum chucks and spring chucks utilize a multi-point support design for thin-walled titanium alloy parts, preventing deformation during machining and achieving a positioning accuracy of ±0.001mm.
3. Full-Process Quality Control System
- Material Testing: Before processing, titanium alloy composition (such as the Al and V content in TC4) is verified using a spectrometer to ensure material purity.
- Process Monitoring: After each process, laser diameter measuring instruments and 2D imaging instruments are used for random dimensional inspection.
- Finished Product Inspection: Full-dimensional inspection is performed using a three-dimensional coordinate measuring machine (accuracy ±0.0005mm) and a blue light scanner, along with mechanical properties tested using a tensile testing machine, to ensure that the finished product meets design standards.
4. Surface Treatment and Process Synergy
Integrating high-end surface treatment processes such as PVD coating, anodizing, sandblasting, and brushing, seamlessly integrates processing and finishing. For example, golf club heads utilize a "sandblasting + spot polishing" process, racing car parts utilize an "anodizing + laser marking" process, and high-end consumer products utilize a "PVD color coating + vacuum oil sealing" process, ensuring a balanced balance of performance and appearance.
IV. Frequently Asked Questions (FAQs)
1. Q: What titanium alloy grades can be processed? What applications are different grades suitable for? A: We process standard materials such as TC4 (GR5, general-purpose, suitable for racing, golf, and consumer goods), TC11 (high-strength, suitable for racing powertrain components), and GR2 (pure titanium, corrosion-resistant, suitable for high-end consumer goods). Customized process testing is available for special materials (such as TC21 and BT20). Material parameters and design requirements must be provided in advance.
2. Q: What is the machining accuracy and surface roughness achieved for titanium alloy parts?
A: Dimensional tolerances are ±0.002-±0.005mm, flatness ≤0.003mm/100mm, and coaxiality ≤0.002mm. Surface roughness is typically Ra ≤0.4μm, reaching Ra ≤0.1μm after polishing and Ra 1.2-2.0μm (matte finish) after sandblasting.
3. Q: What is the lead time for custom racing/golf parts? Can you meet urgent event requirements?
A: Regular small-batch orders (1-10 pieces) have a delivery time of 7-10 days. Emergency racing parts (such as race repair parts) can be delivered within 48 hours. Part complexity and production capacity arrangements must be discussed in advance to ensure the race schedule is not impacted.
4. Q: What surface treatments are supported for titanium alloy parts? Will this affect dimensional accuracy?
A: We support PVD coating (film thickness 0.5-5μm), anodizing (film thickness 5-15μm), sandblasting, brushing, etc. During processing, we reserve a dimensional margin for the surface treatment (e.g., 0.003-0.005mm for PVD coating) to ensure that the finished dimensions meet assembly requirements, with a tolerance of ≤±0.002mm.
5. Q: For custom high-end consumer parts, can we provide trial samples? Will we then proceed to mass production after confirming the results?
A: We support trial samples! We can produce 1-3 samples first, and then initiate mass production after the customer confirms the appearance, dimensions, and texture. The sample trial production cycle is 5-7 days. During the trial production process, the processing and surface treatment process can be adjusted according to the feedback to ensure the final product
