I. Core Advantages of High - Precision CNC Turned Parts
CNC turned parts are widely used in automotive, medical, semiconductor and other fields due to their excellent accuracy and stability. JSJM adopts advanced five - axis linkage CNC lathes and precision cutting tools to ensure that the part tolerance is controlled within ±0.01mm, and the surface roughness can reach Ra 0.8μm. For example, stainless steel turned parts in medical equipment need to meet FDA certification, and their corrosion resistance and biocompatibility are further enhanced through special coating processes. And turning of aluminum parts utilizes the lightweight and high - thermal - conductivity of aluminum to achieve efficient heat dissipation of structural parts in the aerospace field.
II. Differentiated Processes for Stainless Steel and Aluminum Parts
1. Precision Manufacturing of Stainless steel turned parts
Stainless steel materials (such as 316L, 304) are the first choice for medical implants and chemical equipment due to their high strength and corrosion resistance. JSJM optimizes cutting parameters (such as feed rate 80 - 120mm/min, spindle speed 2000 - 3000rpm) to reduce material deformation and adopts electrolytic polishing technology to eliminate burrs, ensuring the surface finish of parts. For example, for a shaft - type part of surgical instruments customized for a medical customer, the stainless steel turned parts process achieves a radial run - out accuracy of 0.005mm.
2. Efficient Machining of Turning of aluminum parts
The machining of aluminum parts (such as 6061, 7075) focuses on the balance between efficiency and accuracy. JSJM uses carbide cutting tools and high - pressure cooling systems to increase the cutting speed to 500m/min, and at the same time reduces vibration through dynamic balancing technology to ensure the machining stability of thin - walled parts (wall thickness ≤0.5mm). A typical case is the lightweight transformation of automobile engine blocks. Through the turning of aluminum parts process, the weight is reduced by 30% while maintaining the structural strength.
III. No MOQ and OEM Customization Services
JSJM breaks the traditional manufacturing model and provides a flexible cooperation mechanism of No MOQ. Whether it is a single - piece prototype verification or small - batch trial production, it can achieve a rapid response through a digital management system. For example, a semiconductor equipment manufacturer urgently needs to customize the vacuum chamber components in parts of semiconductor equipment. JSJM completed the design optimization and first - piece delivery within 7 days, helping the customer to shorten the R & D cycle.
For oem parts machining needs, JSJM supports the whole - process service from CAD drawings to finished products. The production progress is monitored in real - time through the MES system, and DFM (Design for Manufacturability) suggestions are provided to help customers optimize the part structure. For example, for the gearbox gears customized for an automotive OEM manufacturer, the processing cost is reduced by 25% through process optimization, while meeting the IT6 - level accuracy requirements.
IV. Special Challenges in the Medical and Semiconductor Fields
1. Stringent Standards for Medical cnc machining
Medical parts need to meet ISO 13485 and FDA requirements. JSJM processes in a clean - room environment, uses medical - grade stainless steel and titanium alloy materials, and ensures zero defects through 100% full inspection (including coordinate measuring and endoscope inspection). For example, the stainless steel turned parts of intervertebral fusion devices need to meet a surface roughness of Ra ≤0.4μm to promote bone tissue growth.
2. Ultra - High Precision of Parts of Semiconductor Equipment
The semiconductor industry has extremely high requirements for the cleanliness and dimensional stability of parts. JSJM uses anti - static packaging and ultra - precision grinding technology to provide parts of semiconductor equipment for lithography machines and etching machines, such as silicon wafer carriers (flatness ≤0.002mm) and vacuum valve components (leakage rate ≤1×10⁻⁹Pa·m³/s).
