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. A single surface-leveling operation takes about one hour. If uncut areas remain, perform surfacing a second
time. 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: 0.3 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.

coordinate is “-3800.”

Insert a flat cutter (ZEC-A2320) into the cutter holder, bring the tip of the cutter into contact
with the surface of the workpiece table, and secure the cutter in place.
For information on how to secure the cutter in place, refer to page 64 and 65.
