Product Description

Lxk320c-2000 CNC screw car milling machine is the leading variety developed by our company, mainly suitable for processing vacuum pump screw, can process equal lead, variable lead, gradual lead screw. This machine adopts wide number numerical control system, the system is five axis three linkage, the system stability is good. The machine adopts turning milling compound processing structure, high processing precision, fast efficiency. Machining workpiece profile regular, high meshing degree.
One,Structure characteristics of machine tool:

1. Machine tool is equipped with machine tool protective cover. Beautiful appearance, smooth lines, appropriate parts of the operation, good humanity.

     2.The guide rail of the machine bed is grinded after high-frequency quenching, with high rigidity and good wear resistance. Bed saddle rail adopts high-quality rail belt, high positioning accuracy, fast moving response, low speed feed no crawling phenomenon, good shock absorption.
    3.Machine tool guide rail lubrication using centralized intermittent special lubrication pump lubrication, lubrication in time.
    4. The feed axis [Z axis, X axis (milling), Y axis (car)] adopts high precision ball screw through a wide number of servo motor direct drive to achieve no clearance transmission, high transmission accuracy, high positioning accuracy.
   5.Headstock spindle C axis adopts wide number servo motor directly connected with high precision wear-resistant worm gear and worm pair (the worm gear and worm pair is anti-backlash worm gear and worm, the side clearance can be adjusted easily). Spindle is equipped with high precision four-jaw chuck to facilitate workpiece alignment.
   6.The feeding mode of tail seat sleeve is hydraulic feeding, which is convenient for disassembling the workpiece. The stroke is 150mm, which is convenient for clamping the short specification workpiece. Tailstock integral feed rack electric feed for convenient operation.
  7.The machine is equipped with special center frame for vacuum pump rotor. The center frame is supported by three points, which is stable when the workpiece is processed. It can also be supported by two points (the top support can be removed). The center frame adopts open and close structure, convenient to disassemble and assemble the workpiece. The center frame internal leakage channel, convenient chip removal is not easy to nest chip.
  8.The machine is equipped with milling shaft (X axis), turning shaft (Y axis). The milling shaft is equipped with a milling head, which can be rotated horizontally ±30° by B-axis (wide number servo motor drive) to meet the rough milling of rotor spiral Angle profile grooves. B axis is locked by hydraulic locking device, good stability during milling. The turning shaft is equipped with four-station electric vehicle tool rest to meet the coarse and fine turning of rotor profile, with high efficiency.
  9.The machine is equipped with a chip discharging machine to facilitate chip discharging.
