NXK420 CNC external whirl milling machine: 1. The operating side of the machine tool is semi-protective with sliding door. 2, the machine adopts two guide rails, high rigidity, good wear resistance. 55° dovetail rail is adopted for bed saddle rail, which has high positioning accuracy, fast moving response and no creeping phenomenon in low speed feed. 3, machine tool guide rail lubrication using centralized intermittent special lubrication pump lubrication, lubrication in time. 4, The feed axis [Z axis, X axis] adopts precision ball screw, driven directly by servo motor, high transmission accuracy, good positioning accuracy. 5, headstock spindle C axis adopts wide number servo motor directly connected precision wear-resistant worm gear and worm pair (the worm gear and worm pair is variable tooth thickness). Spindle is equipped with four-jaw chuck to facilitate alignment of workpiece. 6, milling head bearing for oil lubrication, synchronous belt drive, milling head motor for high power frequency conversion motor. Milling head spindle inner hole φ 240mm. Milling head with two specifications of cutter head. 7, the machine tool fixture is installed on both sides of the milling head. V type fixture. 8. The tail seat sleeve is thick, and the feeding mode is manual feeding, which is convenient to disassemble the workpiece. Tailstock movement adopts mechanical feed manual locking. 9, the machine is equipped with chip discharging machine, convenient chip discharging machine is equipped with high pressure water pump, processing through forced cooling to achieve lubrication cooling effect. The net cover below the chip discharging machine water pump should be made of small holes to avoid iron filings. Our Factory
