What Are The Advantages of Rolled Lead Screw?

In the field of modern mechanical transmission,lead screw is used as a core component to convert rotary motion into linear motion.The progress of its manufacturing process directly affects the performance of equipment and production costs.Among them,rolled leadscrews stand out with the following main advantages:

(1)Efficient production process

Rolling lead screw adopts cold rolling process,which makes the surface of thread raceway smooth,and the surface roughness can be up to Ra0.5~0.8 μm.In addition,the rolling process avoids vibration threads,cracks,tooth burns,hard points and other defects affecting the fatigue life,which are easy to be produced by the cutting and grinding process.

(2)Accuracy consistency

The trapezoidal screws rolled out from the same batch have high consistency in their important accuracy indexes such as lead accuracy,tooth shape accuracy,center diameter roundness and cylindricity,etc.This means that in mass production,the quality and interchangeability of products can be guaranteed.

(3)High production efficiency

The production efficiency of rolling lead screws is very high,20-50 times higher than that of turning and grinding processing.This efficient production is conducive to the realization of standardized,specialized mass production,which can be delivered quickly.

(4)For special specifications

For ultra-slim (L/D≥50), large and extra-large lead (lead angle φ≥17°), and multi-threaded screws,the use of rolled screws is the best choice.This gives rolled lead crews a special advantage in applications with special specifications.

(5)Economy

Rolled leadscrews have high production efficiency,consistency in size of the same batch of products,good interchangeability,and are easy to assemble in batches. These features make lead screw in the economy has obvious advantages.

(6)Wide applicability

Thanks to its simple structure and insensitivity to contaminants,lead screw is able to adapt to dusty or less clean environments.This characteristic makes it show good environmental adaptability in industrial automation,construction machinery and other diversified application scenarios.In addition,the drive mechanism has reliable self-locking characteristics,which can meet the high demand for positioning retention but not demanding transmission efficiency requirements of engineering applications,such as vertical lifting mechanism or manual adjustment devices.

The popularity of rolled lead screw technology essentially reflects the evolution of manufacturing towards efficiency,precision and sustainability.With the combination of intelligent rolling equipment and new material processes,the boundaries of lead screw application are expanding.For equipment manufacturers,grasping this technological change is not only a demand for cost control,but also a strategic choice to enhance product competitiveness.In the context of Industry 4.0, the roll forming process will certainly drive transmission components into a new performance era.
