3.14 Handwheel Operation
3.14.1 Handwheel Mode
The system supports three operation modes: auto mode, reference point mode and manual mode,
and manual mode is subdivided into jog, stepping and handwheel. Users can select handwheel mode by
pressing ―Handwheel‖ button on the operation panel.
In handwheel mode, users can configure a handwheel to control the machine tool. As shown in Fig.
, select the motion axis by rotating ―Axis selection button‖, select handwheel override gear by
rotating ―Gear selection button‖, and control the selected axis running at the selected handwheel
override gear by rotating ―Handwheel control rotation disk‖. Handwheel override gear regulates the pulse
equivalent sent to the machine tool from the system according to the each case turning of handwheel,
and the displacement (linear displacement or rotation angle) of moving parts of machine tool can be
calculated based on the pulse equivalent.

3.14.2 Handwheel Guide
NK280 system supports handwheel guide.
Handwheel guide refers to a way of operation that the automatic execution speed of machining
program is manually controlle
d during auto processing so as to guard against such problem as ―tool
damage‖ and dangers caused by wrongly loaded program or inappropriate tool path.
Fig. 3-52 is the software interface of handwheel guide, in which press F1 [HW Guide] button to
activate handwheel guide. After machining starts, the system will execute the processing program with
clockwise turning of handwheel and stop processing with the stop of handwheel. Processing speed
varies with the handwheel turning speed.
