1. Removed broken slip ring at C-axis
2. Scale feed back added to Z-axis
3. TCP-KCP added
4. Replaced X-axis sliding covers
5. Added platform in front of pallet changer
6. Lighting fix, cable fix, splash cover fix.
7. Cleaning

1. Removed broken slip ring at C-axis:
For a reliable machine operation, SNK Japan removed the broken
slip ring from C-axis mechanism and rewired without slip
ring. Although the C-axis travel has been limited to
+/- 270 degree, the machine can perform a stable machining
without a risk of slip ring failure.

2. Scale feedback added to Z-axis:
SNK Japan added scale feedback to the Z-axis.

3. TCP-KCP:
SNK Japan added TCP-KCP. It is a function dynamically
compensates for tool edge position errors that occur during
FANUC 5-axis tool center point control (TCP) operation to
improve tool edge positioning accuracy. By correcting in real
time the tool edge position error that occurs during 5-axis
tool center point control (TCP) operation due to slight
mechanical errors during rotation (B and C-axis), the machining
position accuracy of the X, Y, and Z-axis and the
position accuracy of the opposing holes are improved. In
addition, machining position accuracy during continuous
5-axis machining is also improved, making it effective for
aerospace workpieces.

4. Replaced X-axis sliding covers, Broken X-axis sliding cover
has been replaced.

5. Added platform in front of pallet changer:
Platform has been added in front of pallet changer for safety
operation During the workpiece setup. (The original customer
had a large platform that is shared with multiple machines).

6. Lighting fix, cable fix, splash cover fix:
Broken lighting equipment, cable, polycarbonate window have bee
n fixed. Covers such as splash guard
have also been repaired to be functional.

7. Machine thoroughly cleaned, but not repainted, to keep cost down.
