Detailed Introduction

Non-standard stepped transmission shafts are core power transmission components of precision equipment and molds. Long multi-stage shafts undertake high-speed rotary power output; miniature threaded spindles realize precise linear positioning and adjustment; matched gears and flanges ensure synchronous rotation and axial positioning between assemblies. Concentricity and surface smoothness directly determine equipment running noise, transmission accuracy and long-term service life.

All shaft parts adopt full precision customized processing workflow: CNC turning to form multi-step profiles and threads, vacuum heat treatment to improve surface hardness and fatigue resistance, multi-stage cylindrical grinding to eliminate rotational runout, and superfinishing to achieve mirror low-friction surfaces. Each finished shaft undergoes strict concentricity, roundness and dimensional full inspection to meet customer drawing tolerance standards.

Custom manufacturing is fully supported based on 2D/3D drawings or physical samples. Material grade, step layout, thread specification and surface anti-wear treatment can be optimized according to rotating speed, load torque and working environment to satisfy diversified non-standard precision transmission demands.
