The present invention proposes a kind of hobbing method, is applied to the hard crisp material crystal column of cutting non-metal, and preferably carries out through aforementioned slitting mill of the present invention.Hobbing method of the present invention comprises step and (combines Fig. 1 and Fig. 2) as follows:
(i) the nonmetal hard crisp material crystal column of clamping:
For example with jaw 211,212,213 clamping LED (light emitting diode) crystal columns 10 of anchor clamps 210.
(ii) also can further axially rotate nonmetal hard crisp material crystal column:
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 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 the feed step: suspend the nonmetal hard crisp material crystal column of propelling, and nonmetal hard crisp material crystal column wouldn't be cut by flywheel knife.
D. aforementioned feed step of repetitive cycling and time-out feed step are also intermittently cut by flywheel knife and make nonmetal hard crisp material crystal column intermittently contact flywheel knife.
For example link longitudinal screw 230 with second motor 320; Drive longitudinal screw 230 during 320 runnings of second motor and do axially rotation; And with a time-control device 430 control second motor 320 intermittently drive anchor clamps 210 longitudinally directions X advance to flywheel knife 100, and make LED (light emitting diode) crystal column 10 intermittently contact flywheel knife 100 and by flywheel knife 100 cuttings.
In aforesaid step e, preferably comprise following two kinds of aspects:
(i) for example directly control second motor 320 (second motor 320 is required to be a stepper motor) and intermittently this LED (light emitting diode) crystal column 10 is advanced to this flywheel knife 100, make LED (light emitting diode) crystal column 10 intermittently by flywheel knife 100 cuttings with a time-control device 430.
(ii) again for example when second motor 320 adopts a conventional motor, then can pass through first timer 410, according to a period 1 411, periodically stop second motor 320; One second timer 420 according to a second round 421, periodically starts second motor 320; And control the period 1 411 equates with second round 421 but asynchronous, and makes flywheel knife 100 intermittently cut LED (light emitting diode) 10, and detailed description as follows.

Aforementioned gap can effectively reduce by 100 chucking powers of bearing from nonmetal hard crisp material crystal column of flywheel knife, reduces frictional heat; And aforementioned gap has the cooling fluid of being in circulation or chip removal, strengthens the cooling to flywheel knife 100 and this nonmetal hard crisp material crystal column.
When second motor 320 is a conventional motor, can controls jointly through first timer 410 and second timer 420, and make second motor 320 intermittently just change and reverse.Period 1 411 is shorter than second round 421, the stroke of the stroke that makes feed when just changeing withdrawing during greater than counter-rotating.
Based on this variant, the present invention proposes a kind of hobbing method, is applied to the hard crisp material crystal column of cutting non-metal, and preferably carries out through aforementioned slitting mill of the present invention.Hobbing method of the present invention comprises step and (combines Fig. 1 and Fig. 2) as follows:
(i) the nonmetal hard crisp material crystal column of clamping:
For example with jaw 211,212,213 clamping LED (light emitting diode) crystal columns 10 of anchor clamps 210.
(ii) also can further axially rotate nonmetal hard crisp material crystal column:
For example drive jaw 211,212,213 rotations and axial rotation LED (light emitting diode) crystal column 10 with the 3rd motor 330.
E. rotate flywheel knife:
For example drive round sheet flywheel knife 100 along its central shaft rotation with 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 the feed step: along the longitudinal direction with 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. aforementioned feed step of repetitive cycling and time-out feed step are also intermittently cut by flywheel knife and make nonmetal hard crisp material crystal column intermittently contact flywheel knife.
In aforesaid step e, preferably comprise following two kinds of aspects:
(i) for example directly controlling second motor 320 (second motor 320 is required to be a stepper motor) with a time-control device 430 periodically advances this LED (light emitting diode) crystal column 10 to this flywheel knife 100; And periodically make LED (light emitting diode) crystal column 10 away from flywheel knife 100, form and come and go the aspect that advances.
(ii) again for example when second motor 320 adopts a conventional motor, then can pass through first timer 410, according to a period 1 411, second motor 320 periodically reverses; One second timer 420 according to a second round 421, is periodically just changeing second motor 320; And control the period 1 411 less than second round 421, and make flywheel knife 100 intermittently cut LED (light emitting diode) 10.
