BMC-3218/21

  • Outstanding stability and extreme machining ability.
  • The X and Y-axis are mounted with high speed heavy duty roller ways; while the Z-axis is box way designed for heavy load to ensure outstanding stability during cutting.
  • The cross beam is designed with high strength “Internal Circular Wall”, which features excellent torsion-resistant capability, and suppresses cross beam’s structural deformation caused by the big span between slideways.
  • The 3 axes ball screw seats are supported with stop blocks to increase axial rigidity and enhance accuracy.
