The LH51/52 compensates errors arising from the inclination or deflection of a machine tool, and
displays the actual displacement of the machine. Thus, the displayed value accords with the
actual displacement of a workpiece to achieve high-accuracy positioning and machining and
restoration of machine tool accuracy.
Data on display and preset data are held automatically.
Therefore, data is retained even after power is turned off or in case of a temporary power outage.
Bolt hole positions are calculated and displayed by inputting the center point, diameter and
number of holes.
The arc cutting positions are calculated and displayed by inputting the center point and radius of
the arc, the tool bore, feed angle and other data.
The Touch sensor (option) facilitates the setting of a datum point and the measurement of a
workpiece.
Tool coordinating function
Nine coordinates can be set as tool coordinates, and the coordinate of any cutting tool can be
retrieved with a tool number.
Adding function
The sum of the reading from the scale mounted on the cutting tool holder and the reading from the
scale mounted on the carriage can be displayed to show the exact position of the cutting edge of
the tool.
