Spindledrive-Cross Table LPKF XY 60/60 GS
General description
The LPKF XY 60/60 GS is a precision positioning system with air bearings and a monolithic granite sub-structure. It is driven via recirculating ball-screw spindles by DC servomotors. Guidance is by means of air bearings along high-precision granite paths. The object carrier is directly guided in two dimensions in the plane, and thus avoids the typical tilt and pitch errors of serially arranged drive axes. Each axis has a high-resolution linear scale with an exact reference point.This table variant is also available as a system with linear motor for high dynamic applications.

Application
The LPKF XY 60/60 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 3-D measuring systems
Options
• Boom or portal structure for holding additional modules• Z-axis with various ranges of motion or
ranges of accuracy
• Rotating / swiveling unit
• Multi-axis arrangements
• Vacuum clamping table
• 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

The LPKF XY 60/60 GL table version with a linear motor achieves significantly higher dynamic rigidity and accuracy because it does not have elastic transmission elements (spindles).
