Canned Cycle Function
The canned cycles of CNC mills are mainly used for machining holes, including drilling, boring
and tapping. With one program block, you can accomplish one or a full set of hole machining
operation. When continuing hole machining, if there is no need to change hole machining operations,
all the modal data in the program need
n’t to be written, which can greatly simplify the program.
