CNC throughfeed drilling machine N2508

Four individually movable drilling blocks arranged on two gantries ensure maximum productivity. Simultaneous machining of long workpieces or parallel machining of two short workpieces guarantee a highly efficient machining process.

A robust machine frame with integrated workpiece transport system controlled by 16 servo motors forms a reliable basis for precise workpiece positioning.

The panels are fed via a roller conveyor with inclined rubber rollers. Automatic loading allows the machine to be integrated into automated production lines. A conveyor belt system with four separately controlled areas and two simultaneously operating stations as well as an unloading station ensure reduced auxiliary times. The two workstations are driven by frequency-controlled servo motors, which allow fast starting and stopping. The workpieces are positioned separately in each work station.

The work table 3,000 mm x 800 mm  made of robust phenol in combination with the vacuum clamping system ensures maximum accuracy, especially for horizontal drilling.

Vacuum clamping system

  • vacuum cups are activated automatically depending on the panel size

Two independent gantries with four drilling blocks

  • master/slave drive system for the gantries
  • four separate drilling blocks (Y axis / Z axis) for simultaneous machining of two short panels or one long panel
  • cross layout of the four drill heads allows for a minimum hole spacing

Drill head configuration

  • in total 100 drills: 
  • vertical: 21 x 4 
  • horizontal: 3 x 4 in X; 2 x 2 in Y 
  • additional pressure system for maximum precision in horizontal drilling

Guide ruler

  • adjusts the panel in Y direction
  • moves up and down in X direction to secure horizontal pressure

Control

  • IPC with 17“ screen
  • USB port
  • SYNTEC control
  • hand wheel for easy feeding of new workpieces
