Dual spindle CNC cutting machine

Dual spindle CNC cutting machine床 XKNC-100GSOn the basis of XKNC-100G, an 8-station turret, auxiliary spindle, auxiliary spindle holder, and auxiliary spindle cutting holder have been added, which can achieve automatic exchange of processes and secondary processing. Equipped with an automatic feeding machine, fully automatic processing can be achieved. It not only maintains the rigidity and high cutting accuracy of our company's cutting lathe, but also solves the problem of secondary machining under one clamping.

Performance characteristics:

• 1. Guide rail

  

  1. Continuing the century old scraping and grinding technology and ultra precision grinding process inherited from Kitamura, Japan, and equipped with an automatic lubrication system to ensure long-term high precision and stability of the machine tool.

  2. Using a dovetail guide rail structure and HT300 material, it has high strength, good wear resistance, excellent overall design, and good shock absorption effect, ensuring that the machine tool has higher rigidity in high-precision machining.

  
  

  

  1. The Z-axis adopts a double mountain sliding guide rail, which truly meets the requirements of high rigidity and large processing range for automated machining.

  2. The hard rail structure has undergone scraping and grinding treatment on all contact surfaces, with 12-14 scraping and grinding points per square inch, resulting in a natural increase in rigidity.

• 2. Bed structure

  

  1. The bed is designed with a symmetrical structure and rigidity, with the spindle and Z-axis located in the middle of the bed, effectively reducing the impact of thermal stress on positional accuracy.

  2. HT300 material has high strength, good wear resistance, excellent overall design, and good shock absorption effect.

• 3. High precision spindle

  

  1. Axis core: Using * spindle material, after multiple heat treatments and fine processing, it has stronger impact resistance and wear resistance..

  2. Bearing: Imported brand high-precision ball bearings are used, with P4 grade and lifetime maintenance free.

  3. Waterproof: Use imported advanced waterproof rings.

  

  1. The built-in electric spindle can be selected, with a spindle speed of 8000rpm for the Ø 30 specification and 6000rpm for the Ø 42 specification. It is cooled by an oil heat exchanger to ensure high speed and precision of the spindle, greatly improving production efficiency.

  2. The diameter of the spindle through-hole is D38mm and the maximum speed is 4500rpm; The diameter of the spindle through-hole is D25mm and the maximum speed is 6000rpm.

• 4. Auxiliary spindle

  

  Easy tool loading, unloading, and adjustment, fast tool changing, and high positioning accuracy.

  High production efficiency and the ability to operate multiple machines by one person.
