Products
Our products are widely used in automotive, medical, semiconductor, aerospace and other fields to meet customers' pursuit of high quality and innovation
High-precision, heavy-load CNC-machined parts used in equipment frameworks, transmission mechanisms, and connection components, such as machine tool guide rails and robotic arm joints. Designed to ensure stability and durability in demanding applications.
Material and process: Tin bronze (ZQSn6-6-3), aluminum bronze or high-strength alloy steel (such as 40CrMnMo) is used, and the tooth structure is precisely formed by CNC lathe/gear hobbing machine (tolerance ±0.02mm).
Key control: Thin wall deformation prevention requires staged rough and fine processing, rough processing reserves, and heat treatment (such as annealing) after fine processing to release stress; tooth surface hardening treatment improves wear resistance, and the surface roughness of fine grinding reaches Ra≤3.2μm.
