10. BAR PREPARATION
Bar preparation is the machining process which changes the shape of bar tip. It aims to get an improved
insertion process during automatic process. The bar preparation must be selected according to the finger
component the user chose.
a) Chamfering
This very basic and necessary preparation is strongly
recommended to be applied on each bar stock when
a finger chuck is selected.
b) Turning down
Due to strength concern, the maximum finger
chuck size within a guiding channel specification is
limited by its own wall thickness and therefore the
maximum loaded bar stock diameter is limited. To
maximize the bar stock diameter, the user is
recommended to turn down the bar tip as shown.
The maximum bar stock diameter should be kept
1mm below the guiding channel.
