DU1412 (5 Axis) / DW1422 (3 Axis)
Double Column Machining Center

The Pinnacle DU series is designed to provide high-efficiency and high-accuracy machining of complex workpieces with only a single workpiece setup. This means reduced setup time and increased machine accuracy. This machine integrates many fine features, including:

  • Moving beam structure.
  • 45° swiveling spindle head provides high precision 5-axis machining.
  • 15000 RPM built-in type high speed spindle.
  • Rotary table supported by hydrostatic bearing system to reduce vibration and increase rotation smoothness and machining accuracy.
  • A & C-axes equipped with rotary encoder to ensure orientating accuracy.
  • Direct drive on A, C-axis.
  • Linear scales on 3 axes.
  • DCM anti-collision software.
  • Fully enclosed splash guard.

High Rigidity and High Precision Structure on DU Series

  • Rugged structure guarantees superior rigidity and stability.
  • High quality Meehanite cast iron (FC30).
  • Beam elevation is driven by twin ballscrews.
  • Z-axis is equipped with double scales to ensure synchronization of twin ballscrews.
  • Z-axis movement is counter-balanced through twin hydraulic cylinders in combination with the chain mechanism to reduce hydraulic system cost and energy consumption.
  • Heavy duty roller type linear guideways on 3 axes.
Direct Drive
  • The 45° swiveling spindle head is directly driven by a motor, featuring high rotation speed, high acceleration/deceleration, and optimal dynamic response that contributes to increased machining efficiency.
45° Swiveling Spindle Head
  • The spindle is directly driven by a built-in type motor, providing outstanding milling function.
  • A curved-teeth clutch fixing system is mounted at the front end of the spindle, making it also suitable for turning operations.
Applicable Industries

The Pinnacle 5-Axis Double Column Machining Center DU1412 is ideal for a wide range of complex parts machining in various industries, such as:

  • Aerospace
  • Shipbuilding
  • Internal combustion engine parts
  • Precision molds and dies


Integrated Rotary Table with Rectangular Table
  • The rotary table (C-axis) is integrated with a rectangular table with T-slots, enabling it to accommodate larger workpieces.
  • The rotary table is supported by a hydrostatic bearing system, allowing for high rotation speed up to 600 RPM, featuring a turning function.
  • C-axis is directly driven by a high speed, high rigidity motor with minimum indexing accuracy of 0.001°.
