Precision Brass Turned Shaft Core

This type of slender shaft structure, featuring stepped outer diameters and irregular end-face cross-sections, is commonly used as a power transmission core or positioning guide pin in precision drive systems. One end is equipped with a flat or cross-shaped drive head for torque transmission, while the middle section utilizes multi-level steps for axial limitation and radial centering. Micro-holes distributed on the side are typically used for fluid conduction, lubrication injection, or auxiliary locking. These components are widely applicable in internal connection links of instruments, automation equipment modules, and pneumatic/hydraulic elements.

The core of the manufacturing process lies in ensuring straightness under high aspect ratios and strict coaxiality of each stepped outer diameter relative to the central axis, preventing runout or assembly interference during high-speed rotation. Due to the involvement of multiple processes such as turning outer circles, milling end-face drive heads, and drilling side holes, composite machining using high-rigidity CNC lathes combined with CNC machining centers is required. Key controls focus on the dimensional tolerance of the drive head cross-section and the positional accuracy of side holes to ensure structural stability and smooth mating under torsional moments.
