Spindle Driving Gear
As not only the gear and shaft have been
processed for grinding after the carburizing
heat treatment of Chrome-Molybdenum for enough
strength but also the bearing part and gear
part are resupplied with oils automatically,
smooth power transfer of the gear will be
maintained for a long period.
4-4. Feed Gear
Gears and a shaft have been processed for
grinding after a caburizing heat treatment of

resistance thanks to the grinding process after
heat treatment and maintains high precision for
a long period. A clamp device and an electric
control box of each part are installed on the
back face of the arm, and at the bottom part, a
working lamp, etc. are built in.
4-10. Electrical Control Box
