Customization Of Stainless Steel Metal Multi-Head Screw Screw Mechanical Equipment Parts
These custom-manufactured multi-start screw rods are high-efficiency mechanical drive components designed for applications requiring rapid linear motion, high load capacity, and precise positioning.
Industrial Automation & Machinery: High-speed actuators, linear stages in packaging machines, CNC tool changers, and rapid-clamping mechanisms.
Precision Positioning Systems: Components in optical alignment devices, laboratory automation (pipetting systems), and semiconductor manufacturing equipment.
High-Load Mechanical Systems: Adjusting screws for heavy-duty valves, presses, and lifting mechanisms where efficiency and strength are critical.
Specialized Consumer & Commercial Equipment: Height adjustment columns for desks/tables, components in high-end 3D printers, and stage machinery.
We specialize in the custom CNC machining of stainless steel multi-start screw rods (multi-head lead screws). A multi-start thread features two or more independent threads (starts) interwoven along the same shaft, allowing for a significantly larger linear travel per revolution compared to a single-start thread of the same pitch. This design provides faster actuation speeds without compromising mechanical strength. Our products are precision-machined from high-grade stainless steel (such as 303, 304, or 316) to ensure durability, corrosion resistance, and long service life. We offer complete customization, including the number of starts (2-start, 3-start, 4-start, etc.), thread profile (trapezoidal, ACME, square, custom), pitch, length, diameter, and end machining (for bearings, couplings, or handles). These components are engineered for smooth, efficient, and reliable motion transfer in demanding mechanical systems.
| Category | Parameter | Details / Specification |
|---|---|---|
| Base Material | Standard Grades | 303 Stainless Steel: Excellent machinability, good corrosion resistance. 304/316 Stainless Steel: Superior corrosion resistance for harsh environments. |
| Alternative Materials | Alloy Steel, Brass, Aluminum (upon request). | |
| Thread Design | Thread Type | Multi-Start Thread. Common profiles: Trapezoidal (Tr), ACME, Square, or custom. |
| Number of Starts (n) | Customizable: 2, 3, 4, 5, 6, or more independent threads. | |
| Lead (L) | Linear travel per full revolution. Lead (L) = Pitch (P) × Number of Starts (n). Fully customizable. | |
| Pitch (P) | Distance between corresponding points on adjacent threads of the same start. Customizable. | |
| Thread Direction | Right-hand or Left-hand. | |
| Dimensions | Major Diameter (d) | Customizable, typically from 6 mm to 80 mm. |
| Length (L) | Custom cut, up to 2000 mm or longer (dependent on diameter and straightness requirements). | |
| Shaft Ends | Can be machined with centers, turned diameters, threads, keyways, or other features for assembly. | |
| Manufacturing & Precision | Manufacturing Method | Precision CNC Thread Milling or CNC Turning. |
| Dimensional Tolerance | Diameter: h7 or h8 tolerance standard. Custom tolerances available. | |
| Lead Accuracy | Standard Grade: ±0.05 mm per 300 mm. High Precision Grade: ±0.015 mm per 300 mm (upon request). | |
| Surface Finish | Machined finish. Polishing, grinding, or other surface treatments available. | |
| Quality & Testing | Inspection | Dimensional verification, thread profile inspection, surface defect check. |
| Straightness | Can be controlled to tight tolerances (e.g., 0.1 mm/m) for precision applications. | |
| Documentation | Material certificate and inspection report provided. |
