Taichung Turning and Milling Factory | Shaft Design for Home Appliances and Audio Equipment | Roundness up to 0.4um

In home appliances and audio equipment, shafts are responsible for rotation, structural support, and stable operation. Their quality directly affects product lifespan and user experience. JIN YI CHERNG is a precision shaft supplier based in Taiwan, providing manufacturing services for appliance and audio shafts. With experience in cnc machining shafts and process planning, we support customers from design development to mass production. Whether for audio mechanisms, or small internal appliance shafts, we can produce custom parts based on drawings or functional requirements.

Machining Size & Accuracy

• Machining Outer Diameter: Ø0.5–60 mm
• Machining Length: 2–1300 mm

1. What benefits come from stable precision?

• Reduced operating noise
• Smoother rotation performance

2. What issues may happen if precision is unstable?

• Noise during operation
• Unstable or rough rotation

Shaft Design Integration & Machining Planning

In shaft production, not only dimensional accuracy matters, but also how design and machining processes are integrated. Early planning helps reduce redesign risks and improves assembly performance.

• Shaft diameter and fit tolerance design
• Machining methods and process planning
• Material selection and strength requirements
• Assembly conditions and operating environment
• Cost control and mass production feasibility
