General description

The LPKF XY 74/74 G is a precision positioning system with a monolithic granite substructure.The combination of newly developed compact guides and highresolution
measuring systems in this Cross Table enables it to be used for processing and checking of structures from the macro to the micro range. It cannot only reach precisely to a specific position but also follow predetermined movement paths with micrometer accuracy.

Application

The LPKF XY 74/74 GS Cross Table is particularly used in machines which place high demands on path accuracy with moderate dynamic performance. These include:

• Laser cutting and engraving systems (e.g. photo templates)
• Sensitive microassembly systems
• Optical inspection systems
• Medical engineering systems
• Precise 3D-measuring systems

Options

• Boom or portal structure for holding additional modules
• Multi-axis arrangements
• Vacuum clamping table
• Granite or steel stand
• Increased accuracy through error compensation
  in both axes after laser calibration
• Increased guidance accuracy through tolerance specification of the
  guide surfaces
• Safety measures around the system
• Increasing the resolution
• Control with the LPKF MotionSystem®
  (e.g. synchronous operation of up to 6 axes)
• Increased accuracy through more precise position measuring
  systems
• CAA field correction
• Integration into user-specific machine concepts
• Accessories and protective devices
• Testing protocol
