SUS304 Precision CNC Shafts - Combined Turning & Milling for Medical

SUS304 Precision CNC Shafts - Combined Turning & Milling for Medical are high-quality 304 stainless-steel shafts machined using combined turning and milling to produce complex geometries and consistent, repeatable dimensions. They deliver excellent corrosion resistance, hygienic smooth finishes, and tight tolerances suited to medical instruments and device assemblies. Selling points: medical-grade SUS304 material, multi-axis combined machining for complex features in a single setup (faster lead times, lower cost), tight tolerances and low-Ra surface finish, customizable designs and short-run flexibility, and strong process control/traceability for medical manufacturing.

Material: stainless steel/ sus304

Characteristics: Cnc Machining Part with high dimension accuracy and many geometric tolerances requirements, except for rotating machining and still need the milling hex shape, we will take CNC to take the combined machining which can make the part in one time to avoid the repeatedly clamping to result in the over-sized for the tolerances.

Precision Stainless Steel SUS304 CNC Machined Parts – Custom High-Accuracy Turning Shafts for Aerospace

MaiJin Metal's Precision Stainless Steel SUS304 CNC Machined Parts are engineered to meet the rigorous demands of aerospace applications, combining advanced manufacturing techniques with premium materials for unmatched performance. Crafted from stainless steel SUS304, these parts deliver exceptional corrosion resistance, high tensile strength, and durability in extreme environments.

Key Advantages:

1. Ultra-High Precision: Achieves tight dimensional accuracy (±0.005mm) and complex geometric tolerances through CNC combined machining, integrating turning, milling, and hex-shaping in a single setup. This eliminates errors from repeated clamping, ensuring consistency for critical aerospace components.

2. Advanced CNC Technology: Seamlessly combines CNC turning and milling processes to produce intricate features like hex shapes, grooves, and threads in one operation, reducing production time and enhancing structural integrity.

3. Superior Material Properties: SUS304 stainless steel offers excellent resistance to oxidation, thermal stress, and chemical exposure, ideal for high-stress aerospace systems.

4. Smooth Surface Finish: Precision machining minimizes post-processing, delivering ready-to-install parts with exceptional surface quality for reduced friction and wear.

Applications:

Designed for the aerospace industry, these CNC machined shafts and components are perfect for actuators, landing gear systems, turbine assemblies, and navigation equipment. Their high accuracy and reliability make them critical for flight control mechanisms, satellite instrumentation, and engine mounts where zero-failure performance is non-negotiable.

What type of parts does MaiJin Metal service make? What services do you offer?

We manufacture custom metal and plastic parts from bar or tube stock to the highest standards of quality and precision. We provide CNC Swiss machining, CNC turning and milling, and two types of centerless grinding.

What's the difference between a lathe, a screw machine, a truning center, and a CNC lathe?

In its simplest form, a lathe is a machine that can make turned parts from bar stock, but has no milling capability. Screw machines, turning centers, and CNC lathes are lathes that have the ability to turn and mill parts. Turning centers and Swiss lathes can typically make more complicated parts than screw machines, and are better-suited for parts with tight engineering tolerances. Swiss lathes tend to be better for small, thin, and long parts than screw machines and turning centers.

What does "CNC" mean, exactly?

CNC stands for “computer numerical controlled” and refers to an automated manufacturing process in which pre-programmed software controls the movement of the machinery. CNC provides the consistent accuracy that makes it possible to produce precision parts.
