The XK9350 series CNC thread rolling mandrel crescent slot milling machine is suitable for processing rolling mandrels with diameters less than 500mm and lengths less than 2500mm. It can automatically process crescent slots, equal rib grooves (fully compliant with GB1499-2018 standard) for φ6~φ50 thread rolling mandrels in various specifications. The machine can automatically machine crescent slots with different helix directions and arbitrary helix angles according to customer requirements, and can be divided or not divided evenly around the circumference of the rolling mandrel; it can also automatically engrave product specifications, grades, trademarks, and other markings at any position on the rolling mandrel (excluding XK9350F, MTC2540). It can also process non-standard rolling mandrels with arbitrary slot shapes, texts, and markings according to user requirements. It achieves the purpose of highlighting functions and multi-functionality.

The milling head features a new-type rolling arc guide rail support, which resolves the rigidity issue of the head support and significantly enhances sensitivity in rotation direction and positioning accuracy. The head motor is powered by a high-power 2.2KW motor, ensuring stability during the cutting process.

Machine tools use ball screw drive longitudinally (to avoid the inaccuracies of rack and pinion drive), with a CNC system for automatic control. It can automatically move from one hole pattern to the next, with precise positioning and no need for manual movement by the operator.

The lathe tailstock features a fixed center + high-precision tailstock rotating spindle structure, eliminating the issue of insufficient support rigidity that comes with using a standard movable center.
