X/Y-axis rapid displacement: 60m/min.
Z-axis rapid displacement: 48m/min.
The series of models are applicable to conditions for batch production, long workpiece clamping time, etc.
They are applicable to the high-precision and high-speed automatic switching table system.


High-rigidity and high-precision structural design

  1. The main structural casting is made of high-quality cast iron. Due to the finite element analysis, reasonable structural strength and stiffening ribs, high rigidity is realized.
  2. The base is ultra-wide. The columns are the box type structure. The saddle is widened and lengthened. With the full load support design, the structure is solid, and the load capacity can be ensured during machining.
  3. The ribs are set in the spindle head to reinforce the structure. The length of the contact part between the spindle head and column is appropriate, therefore, the spindle can be securely supported.

High-rigidity and high-speed feeding system

  1. The three-axis motor and precision high-speed ball screws are subject to straight transmission, thereby improving the rigidity and precision.
  2. The brake motor system is used on the Z axis and can keep high degree of balance and sensitivity in the rapid displacement, thereby ensuring the machining accuracy.
  3. The linear slide rails with high rigidity, low noise and low friction characteristics are used on the three axes to realize rapid displacement and obtain the best circulating accuracy.
  4. The best accuracy can be obtained by measuring with the BALL BAR instruments and adjusting the parameters in advance.
