(i) clamp nonmetal hard crisp material crystal column:
For example clamp LED (light emitting diode) crystal columns 10 with the jaw 211,212,213 of fixture 210.
(ii) the also further nonmetal hard crisp material crystal column of axial-rotation:
For example drive jaw 211,212,213 rotations and axial rotation LED (light emitting diode) crystal column 10 with the 3rd motor 330.
A. rotate flywheel knife:
For example drive round sheet flywheel knife 100 along its central shaft rotation with the first motor 310.
B. feed step: along the longitudinal direction nonmetal hard crisp material crystal column is advanced to flywheel knife, and make nonmetal hard crisp material crystal column contact flywheel knife and cut by flywheel knife.
C. suspend feed step: suspend and advance nonmetal hard crisp material crystal column, and nonmetal hard crisp material crystal column wouldn't be cut by flywheel knife.
D. the aforementioned feed step of repetitive cycling and time-out feed step, and make nonmetal hard crisp material crystal column intermittently contact flywheel knife and intermittently be cut by flywheel knife.
For example link longitudinal screw 230 with the second motor 320, the second motor 320 drives longitudinal screw 230 to make axial-rotation while running, and with a time-control device 430 control the second motor 320 intermittently drive fixture 210 longitudinally directions X advance to flywheel knife 100, and make LED (light emitting diode) crystal column 10 intermittently contact flywheel knife 100 and be cut by flywheel knife 100.
In aforesaid step e, preferably comprise following two kinds of aspects:
(i) for example directly control the second motor 320 (the second motor 320 is required to be a stepper motor) with a time-control device 430 and intermittently this LED (light emitting diode) crystal column 10 is advanced to this flywheel knife 100, LED (light emitting diode) crystal column 10 is intermittently cut by flywheel knife 100.
(ii) again for example in the time that the second motor 320 adopts a conventional motor, can pass through first timer 410, according to a period 1 411, periodically stop the second motor 320; One second timer 420, according to a second round 421, periodically starts the second motor 320; And control that the period 1 411 equated with second round 421 but asynchronous, and make flywheel knife 100 intermittently cut LED (light emitting diode) 10, be described in detail as follows.

For example drive round sheet flywheel knife 100 along its central shaft rotation with the first motor 310.
F. feed step: along the longitudinal direction nonmetal hard crisp material crystal column is advanced to flywheel knife, and make nonmetal hard crisp material crystal column contact flywheel knife and cut by flywheel knife.
G. suspend feed step: along the longitudinal direction by nonmetal hard crisp material crystal column away from flywheel knife, and nonmetal hard crisp material crystal column wouldn't be cut by flywheel knife, and and the knife edge of flywheel knife between form a gap.
H. the aforementioned feed step of repetitive cycling and time-out feed step, and make nonmetal hard crisp material crystal column intermittently contact flywheel knife and intermittently be cut by flywheel knife.
In aforesaid step e, preferably comprise following two kinds of aspects:
