Products Description

CNC turned parts manufacturer specializes in producing rotationally symmetric and complex shaft parts, precision-manufactured from various high-performance stainless steel materials using computer numerical control (CNC) turning technology, specifically designed for battery systems, chemical equipment, medical instruments, and high-value industrial machinery. Unlike general-purpose machined parts, the core of this product lies in "using turning technology as a foundation and integrating multi-process composite machining," enabling efficient and high-precision cutting of components with complex external diameters, internal holes, threads, grooves, and end face features from stainless steel bars or tubes.
Product Advantages
Exceptional Precision
Utilizing a dual-station synchronous machining process and an online real-time measurement system for stainless steel CNC milling, ensuring a corner roundness of ≤0.01mm and a milling flatness of ≤0.02mm, significantly superior to the industry average.
Superior Surface Finish
Offering both electropolishing (Ra0.2μm) and grinding (Ra0.4μm) processes, not only enhancing the appearance and texture but also significantly reducing the coefficient of friction and extends stainless steel rolling mill service life.
Strong Material Compatibility
Specializing in milling 304 stainless steel machining (such as 304, 316L, 2205, etc.), while also supporting efficient machining of challenging materials such as titanium alloys and aluminum alloys.

Detailed Display
Microscopic Surface Morphology Comparison
Using scanning electron microscopy (SEM) or white light interferometry, the microscopic morphology of the turned surface and the electropolished surface are compared. The latter exhibits a smooth, wavy appearance for milling 316 stainless steel, without directional tool marks, and a significantly reduced peak-valley height.
Complex Internal Cavities and Deep Hole Structures
The internal structure of sleeve-like parts with radially intersecting holes, internal steps, and internal threads, machined by a combination of turning and milling, is displayed. The milling stainless internal surface finish is consistent.
Thin-Walled Part Cross-Section
Measurement data and metallographic images of the wall thickness uniformity of thin-walled sleeves are presented, demonstrating no deformation and good control of the work-hardened layer for stainless steel CNC milling.

Design Advantages
Stable and Durable Design
Utilizing high-purity 304/316L stainless steel, the optimized structural stress points enhance mechanical strength and fatigue resistance, enabling stable operation in complex industrial environments for extended periods, with a service life exceeding 15 years. Electropolished surfaces further improve corrosion resistance, reducing maintenance and replacement costs for stainless steel rolling mill.
Customizable Design
Supports customization of multiple specifications, irregular structures, and complex threaded milling 304 stainless steel. Product dimensions, structure, and precision levels can be flexibly adjusted according to customer engineering drawings and assembly requirements, eliminating the need for additional adjustments to equipment assembly schemes. This adapts to personalized project needs and improves project adaptation efficiency.
Convenient Assembly Design
Optimized milling 316 stainless steel structure, employing precise positioning grooves and clear threads, enables rapid assembly and disassembly, reducing assembly time. A smooth, burr-free surface prevents scratches to operators and equipment parts during assembly, enhancing assembly safety and convenience.
