What is Trapezoidal Screw
Trapezoidal screw use: widely used in machine tool transmission system, automation equipment feeding mechanism, lifting machinery lifting device, etc., is the core component to achieve linear motion.
Geometric characteristics: It has a continuous trapezoidal thread structure, with high thread accuracy (pitch, tooth profile angle) and surface roughness, and a large length-to-diameter ratio is easy to deform.
Common risks: Traditional machining is prone to problems such as thread accuracy deviation, substandard surface roughness, workpiece deformation, and fast tool wear, leading to production delays or increased scrap.

Trapezoidal Screw Whirling Core Pain Point
- Low efficiency: The traditional processing of trapezoidal screw cycles is as long as 6 minutes/piece, which cannot meet the needs of mass production;
- High scrap rate: insufficient manual control accuracy, scrap rate as high as 8%;
- High maintenance costs: poor equipment stability, frequent replacement of wearing parts;
- Slow service response: Overseas equipment manufacturers have a long after-sales cycle, which affects production continuity.
