Mengxiang Precision | Brass Flange Trapezoidal Lead Screw Assembly for Smooth and Durable Transmission

As a linear motion conversion unit in mechanical transmission systems, this assembly consists of a precision trapezoidal external thread rod combined with a brass flange featuring mounting holes. The wide flange surface provides a stable axial reference, effectively dispersing locking stress to prevent loosening. The internally machined threads mesh tightly with the high-strength external screw, ensuring smooth transmission and positioning accuracy during frequent reciprocating motions. It is commonly used in CNC machine tool feed mechanisms, fine-tuning modules for automation equipment, and lifting control scenarios for valve actuators.

The manufacturing process relies on composite CNC turning and milling techniques, with strict control over the perpendicularity of the flange face relative to the screw axis, as well as the pitch diameter tolerance and thread profile regularity. This prevents wobble or binding after assembly. Given that brass is soft and prone to tool adhesion, cutting parameters are optimized to suppress deformation and eliminate burrs. Special attention is paid to fine chamfering at the flange edges and thread roots, ensuring operational safety and meeting the aesthetic cleanliness requirements of clean environments. For tight clearance fits, outer diameter tolerances are strictly controlled to ensure smooth insertion and removal without looseness.

Equipped with high-precision CNC lathes, machining centers, and coordinate measuring machines (CMM), our factory supports non-standard customization based on 2D/3D drawings. We accommodate various materials (such as H59/H62 brass and tin bronze), thread standards (such as Metric Tr and Imperial Acme), and flange dimensions. Adhering to the ISO 9001 quality management system, our production process covers material traceability, go/no-go gauge inspection for key dimensions, and 100% visual inspection. We provide material certificates and test reports to ensure that batch-delivered products meet the stringent standards for mating precision and wear resistance required by mechanical manufacturing, semiconductor equipment, and high-end automated production lines.
