CNC Machined Quick Change Drive Shaft with Knurling & Cross Hole for Fixture Tooling (Stainless Steel)
Description
This product is a CNC machined drive shaft specially designed for industrial automation and fixture tooling fields, serving as a core connecting and transmission component in quick-change fixture systems. It integrates multiple precision machining processes, including CNC turning, CNC milling and optional knurling, which can be completed by ordinary CNC lathes without the need for Swiss-type lathes, effectively controlling production costs while ensuring processing efficiency. The product adopts a stepped shaft structure with a square end and cross hole, which realizes precise torque transmission and quick locking functions, and the optional knurled surface (or alternative anti-slip treatment) facilitates manual operation and adjustment. Made of high-quality carbon steel or stainless steel, it has excellent wear resistance and structural strength, and can be customized in size, material, surface treatment and other aspects according to customer drawing requirements, widely applicable to automation equipment, fixture positioning, torque transmission and other scenarios, perfectly matching the diversified needs of CNC machining services.
