Technical Information - NC Cycle

Use the NC cycle as instructed below to optimize tool performance more safely.

1. Start NC operation cycle

2. Oil pressure head moves until
it touches the workpiece

Set the starting point of the main axis of the tool so
that the guide pad remains inside the guide bush
when the oil pressure head moves forward.

3 ˜ 5 mm 3. Move tool workpiece
Move the tool 3 to 5 mm from the edge of the workpiece.
If the available NC machine can support this approach,
the operation process may start from this point
