Success Cases

Value We Create for Customers

Aerospace

Aerospace Titanium Alloy Structural Component 5-Axis Machining Project

Material: TC4 Titanium (Ti-6Al-4V) Precision: ±0.005mm Output: 2,000 pcs/month

Titanium alloy fuselage structural components for an aerospace customer, featuring complex shapes with multiple spatial curved surfaces and deep cavities. TC4 titanium alloy is notoriously difficult to machine. Yikai Precision used 5-axis simultaneous machining centers with specialized tooling and cooling solutions, achieving ±0.005mm machining accuracy and Ra0.4μm surface roughness. By optimizing tool paths and cutting parameters, machining efficiency improved by 40% compared to the customer's previous supplier, while reducing costs by 15%.

Medical Device

Medical Device Stainless Steel Precision Bushing Mass Production Project

Material: 316L Medical-grade Stainless Steel Precision: ±0.003mm Output: 50,000 pcs/month

316L stainless steel bushings for a medical device customer, used in surgical robot joints. Inner hole accuracy ±0.003mm, roundness 0.002mm, surface roughness Ra0.2μm, requiring 120-hour salt spray testing. Yikai Precision used a combination of CNC turning + precision internal grinding + electropolishing, establishing a dedicated medical parts production line for stable mass production. Products passed the customer's ISO 13485 medical quality system audit, with defect rate controlled below 0.1%.

New Energy Vehicle

New Energy Vehicle Aluminum Alloy Motor Housing Machining Project

Material: ADC12 Aluminum Die Casting + 6061 Aluminum Precision: ±0.01mm Output: 10,000 pcs/month

Drive motor housings for a new energy vehicle customer — large volume, thin walls, prone to deformation, with multiple precision bearing bores and cooling channels. Yikai Precision used horizontal machining centers with a dedicated flexible fixturing system, solving the clamping deformation problem of thin-walled parts. Aging treatment after roughing relieves internal stress before finishing, ensuring bearing bore position and concentricity. Dimensional pass rate reached 99.5%, helping the customer achieve domestic substitution of motor housings.

Precision Instrument

Precision Instrument Brass Gear Set Precision Machining Project

Material: H62 Brass Precision: Cumulative pitch error ≤0.01mm Output: 30,000 sets/month

Brass gear sets for a precision instrument customer, containing 5 gears of different specifications for optical instrument focusing mechanisms. Module 0.3mm, 12-80 teeth, cumulative pitch error ≤0.01mm, tooth surface roughness Ra0.8μm. Yikai Precision used a complete process chain of precision CNC turning + gear hobbing + deburring + cleaning, establishing a dedicated gear inspection room with a gear measuring center for full-parameter inspection. Products transmit smoothly with low noise, completely replacing the customer's previous Japanese-imported gear sets at 60% cost reduction.
