This display unit has functions especially suitable for milling which enable easy-to-learn
operations, reduced machining time and higher-accuracy machining.
The minimum display unit can be selected from the following according to the connected scale.
Magnescale axes : 0.0005 mm, 0.001 mm, 0.005 mm, 0.01 mm and diameter display
(0.00002", 0.00005", 0.0001", 0.0005" and diameter display)
GA axes : 0.005 mm, 0.01 mm and diameter display
(0.0002", 0.0005", 0.001" and diameter display)
Digiruler axes : 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm and diameter display
(0.0005", 0.001", 0.002", 0.005" and diameter display)
The LH61 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.
The Touch sensor (option) facilitates the setting of a datum point and the measurement of a
workpiece.
When a scale with built-in absolute zero point is connected, the absolute zero point on the scale
(fixed point) can be detected wherever the scale stands. The detected fixed point is useful as the
absolute zero point for machining.
Moreover, any offset amount from the absolute zero point can be set and recalled easily, which is
useful for setting the absolute zero point on a boring machine or the like.
Program creation mode
• Manual programming in EDIT mode.
• Playback programming: program is made as maching is actually performed.
Program execution mode
• Machining sequence is displayed step by step.
• The data for each axis can be reversed with the mirror image function.
Bolt hole circle
• Bolt hole positions are automatically calculated and displayed by entering parameters such as
the circle center/diameter and number of holes.
Up to 10 points can be stored in memory in ABS coordinates.
The following input/output is possible via RS232C.
• Key operation input and display data output.
• Program data input and output.
