Surface Leveling Of The Workpiece Table - Roland EGX-350 User Manual

5-3 Surface Leveling of the Workpiece Table

This adjusts the flatness of the surface of the workpiece table by cutting the table surface to a uniform depth. This
operation is called "surface leveling" or "surfacing."
This can be useful in cases where rigorously precise flatness is required, such as for plate engraving performed without
using the nose unit. The operation takes approximately one hour to complete. Also, pausing this operation while in
progress is possible, just as with ordinary cutting.

Verifying the Cutter Used and the Settings
➣
Cutter used: Included flat cutter (ZEC-A2320)
➣
Z-axis origin point (Z0 position): Surface of the workpiece-table center
➣
Lock-lever position:
➣
Spindle speed: 14,000 rpm*
➣
Cutting-in amount: 0.2 mm (invariable)
➣
Cut-out amount: 1 mm (invariable)
➣
Feed rate: 15 mm/sec. (invariable)
➣
Cutting area: Entire X- and Y-axis operating range (invariable)
* The speed of spindle rotation at the time surface-leveling cutting starts is always 14,000 rpm. Watch the status of
cutting and modify this as required.
