The boring spindle is one of the core components of a CNC boring and milling machine. Since its operational condition directly impacts the machine tool’s performance and the machining quality of parts, stringent dimensional and geometric tolerances are required for the spindle.
As the level of intelligence in manufacturing continues to advance, CNC machine tools—as core equipment in modern manufacturing—face increasingly stringent demands for automation and machining precision.
As core components bearing complex mechanical properties, the integrated forming process of complex-shaped components directly impacts vehicle performance enhancement and material efficiency optimization.
Ultra-thin-walled metal component machining serves as a key indicator of precision manufacturing capability. While current internationally leading roll forming processes can produce “tearable steel” sheets as thin as 0.03mm, they face limitations such as limited processing versatility and high equipment dependency.
With the advancement of manufacturing technology, complex structural components are increasingly applied in equipment manufacturing, driving simultaneous demands for higher machining precision and consistency.
Steel is a vital material for industrial development. The continuous advancement of its cutting and processing technologies enables the production of more precise and complex components, meeting the practical demands of manufacturing and other industries.
Driven by advancements in electronics, information technology, materials science, and other high-tech fields, traditional manufacturing techniques are undergoing profound transformation, rapidly evolving toward digital manufacturing technologies.
In the mechanical manufacturing industry, hole machining is generally classified into deep hole machining and shallow hole machining based on the length-to-diameter ratio.
The rotating sleeve (Figure 1) has an outer contour with undercut, multiple arcs, an M22×1.5 thread, internal bores, and compact dimensions.
With the rise of industrial automation and intelligent manufacturing, CNC machining has become key to improving automation, quality, and efficiency in mechanical production.
