Customizable Stainless Steel Turned Parts End Machining For Industrial Applications

Our trapezoidal lead screws are manufactured using high-quality 304/316 stainless steel (specialty stainless steels such as 440C are also available upon request), establishing a solid quality foundation from the source:

• Superior Corrosion Resistance: Stainless steel inherently offers excellent rust resistance, acid/alkali resistance, and corrosion resistance. Perfectly suited for complex working conditions such as humid, dusty, outdoor, and chemical environments. Long-term use without rusting or oxidation. Service life is more than three times that of ordinary carbon steel lead screws.
• High Rigidity & Wear Resistance: High material hardness and structural strength provide excellent impact resistance and fatigue resistance. Capable of handling heavy-load transmission without deformation or breakage, ensuring long-term stable equipment operation.
• Hygienic Grade Compatibility: 304/316 stainless steel meets food-grade and medical-grade standards, making it directly suitable for food machinery, medical devices, and other applications with high hygiene requirements. No heavy metal leaching, safe and environmentally friendly.

This lead screw is manufactured using a dual-process approach of CNC 5-axis turning + precision rolling/grinding, achieving industry-leading precision:

• Precision Trapezoidal Thread Forming: High-precision rolling processes ensure full thread profiles and accurate pitch. Thread surface finish reaches Ra 0.8 or better, resulting in low friction, low noise, and high efficiency during transmission.
• Integrated Machining, Maximum Concentricity: The screw body, transmission threads, and end connection structures are all machined in a single setup. Concentricity is strictly controlled within 0.01mm, ensuring no eccentricity or vibration during transmission.
• Customizable End Machining: Keyways, flats, threaded holes, steps, and other features can be machined as required, perfectly matching your motors, couplings, sliders, and other mating components.
• Full-Process Quality Control: Every lead screw undergoes 100% inspection using CMMs, thread measuring instruments, and laser interferometers before leaving the factory, ensuring pitch error, straightness, and surface roughness are 100% compliant.

This stainless steel trapezoidal lead screw serves as a universal core for mechanical transmission, covering nearly all high-end fields requiring linear motion:
