Central bore is the precision-machined axial opening in a hollow spindle that enables tool passage, coolant flow, and workpiece support in machining operations.
The central bore is a critical cylindrical aperture running concentrically along the longitudinal axis of a hollow spindle. It serves as the primary conduit for tool shanks (in live tooling applications), coolant/lubricant delivery systems, and bar stock/material feeding mechanisms. Engineered with precise dimensional tolerances and surface finishes, it maintains rotational balance, minimizes vibration transmission, and ensures alignment with machine tool axes. In CNC lathes and machining centers, it directly influences maximum bar capacity, tool clearance, and chip evacuation efficiency.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
Bore diameter determines maximum bar stock size for turning operations and tool shank clearance for live tooling. Larger diameters reduce spindle stiffness but enable bigger workpiece handling.
Regular cleaning with non-abrasive tools, inspection for scoring/ovalization, monitoring coolant contamination, and verifying concentricity during preventive maintenance cycles.
Limited honing/grinding is possible within tolerance limits, but excessive wear typically requires spindle replacement or specialist boring/coating restoration.
