PRODUCTS / HIGH SPEED DOUBLE COLUMN MACHINING CENTER

SDC Series |
1612 / 2212 / 3212

A NEW GENERATION OF HIGH SPEED DOUBLE COLUMN MACHINING CENTER


This machine features optimal cost-to-performance ratio. All models in this series have a modular design and an enhanced machine structure, exhibiting high speed, high precision cutting performance and increased machine stability. These machines can fully satisfy the requirements for precise complex surface machining and mold machining in various industries. The SDC series could be widly applied to the high-tech industries such as: aerospace, automotive and motorcycle, energy, electronics and transportation.

 

    ROLLER TYPE LINEAR WAYS ON THREE AXES

  • All three are mounted with roller type linear ways. The X-axis (table) uses #55 linear ways with 6 blocks. The Y/Z axes use #55 linear ways. The Y-axis linear ways are heavy duty type with rigidity increased by 70%, making the machine suitable for high speed, high rigidity machining for the long term.

 

    HIGHLY RIGID MACHINE STRUCTURE

  • The massive base is a box type structure in combination with internal rib reinforcement. Employs 55mm high rigidity roller type linear ways and one grade increased Ø63mm ballscrews. These provide a dependable foundation to ensure high accuracy in high speed machining.
  • The oversized columns are of honeycomb structure with higher stability than others. This also provides better geometric accuracy maintaining capacity compared to conventional structures. The columns and the cross beam are one-piece fabricated. The contact surfaces of all parts have been scraped for higher accuracy of the machine, which in turn provides the best dynamic and static rigidity.

  • The joint parts among the saddle, spindle head and cross beam are of stepped structure (top/side) design, which helps to boost stability when the Y axis moves at a high speed, reducing vibration and tilting forward to enhance the high speed cutting rigidity of the spindle. This results in higher machining accuracy.
  • All machine parts are subjected to analyze by using the Finite Element Method (FEM), which provides a light configuration after assembling, while ensuring the optimal rigidity of the machine.
  • The table is a box-type structure with rib reinforcement to increase loading stability and machining accuracy.
  • The series of machine is manufactured from high durability cast iron (FC-300), and they are assembled after high precision grinding and scraping.

BUILT-IN TYPE SPINDLE WITH HIGH POWE

  • Standardly equipped 10,000 rpm BT50 direct-drive spindle.
  • The high speed, high rigidity spindle is suitable for high speed and high precision machining needs on molds.
  • The spindle is supported by high precising, large ceramic bearings, providing outstanding axial and radial cutting rigidity (direct-drive type).
  • The powerful built-in type spindle provides power output of 15/18.5KW and maximum torque of 118Nm.

 

 

 

THREE AXES BALLSCREWS DIRECTLY COUPLED TO MOTORS

  • Employs a powerful axial servomotor to directly drive the highly rigid ballscrew with double nuts, pretension treated by thermal growth in advance to upgrade positioning accuracy.
  • Three axes transmission and end supports on all machine models are completely scraped to achieve the actual geometric surfaces.
  • Specially designed forced positioning restriction on axis.
  • Rapid traverse rates on three axes (X/Y/Z): 24/24/24 m/min.

STEPPED STRUCTURE ON Y-AXIS WITH TWO LINEAR WAYS

  • The saddle, saddle slideways and the cross beam are compactly constructed with 90° design, allowing them to resist axial and radial tensile force, shear force, and various pressure fluctuations.

PRACTICAL, DEPENDABLE CONTROL FUNCTION

  • The improved operation panel meets CE regulations with elegant outlook.
  • The seat type operation box makes operation free.
