1.10
Superior quality material with special treatment for the wear-resisting purpose has been
used for transmission parts such as gears, worm and worm shaft, rack, lead screw etc as
well as for some key parts like spindle and spindle quill.
1.11
An adjustable safety protection clutch in the spindle feed device is available in order to
prevent the machine and tools from damage when overloaded.
1.12
A safety protection guard under the spindle box is available as it is not only prevent
coolant splash while cutting but also could observe the machining status.
The guard is interlocked with the spindle, so when the guard is opened, the spindle
could not be running until the protection guard keeps his position.
