JUNHUAN_SlewingBearing :

The hole milling process of slewing bearing on CNC machining center is a key forming procedure for mounting holes, lubricating holes and positioning holes of slewing rings. After rough turning and gear machining, the slewing blank is clamped precisely by special fixture on the machining center. Multi-axis linkage CNC milling is adopted to complete hole drilling, rough milling, finish milling and chamfering in one clamping. This integrated process ensures uniform hole spacing, high dimensional accuracy and smooth inner hole surface, effectively eliminates clamping errors from repeated positioning. It improves processing efficiency and guarantees assembly matching precision for engineering machinery, cranes and wind power slewing bearings.
