The positioning accuracy of a machining center directly affects machining quality and production efficiency.
To ensure high-precision operation of the equipment, regular testing of its positioning accuracy is crucial.
Linear motion positioning accuracy testing
This testing method is a key indicator for evaluating whether each coordinate axis of a machine tool can accurately reach its predetermined position under the control of the CNC system.
A laser interferometer is typically used for measurement to ensure high precision.
The specific method involves performing multiple positioning operations on each coordinate axis under no-load conditions on the machine tool and worktable, recording the actual position each time, comparing it with the commanded position, and calculating the error value.
This method can accurately evaluate the positioning accuracy of the machine tool.
