Product Application:

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.

Product Description:

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.
