When home roll to be processed was rotated in a first direction, also along the major axes orientation continuous moving, wire casing was a continuous spiral groove.
When also can adopt home roll to be processed to be rotated in a first direction, also along the major axes orientation intermittent movement, wire casing comprises a plurality of coaxial cannelures.
The shape of above-mentioned wire casing is corresponding with the shape of milling cutter, and the diapire of wire casing is arc.
Above-mentioned wire casing has relative the first side wall and the second sidewall, and the angle of the first side wall and the second sidewall is the 30-70 degree.
The angle of preferred the first side wall and the second sidewall is the 30-50 degree.
Above-mentioned milling mechanism also comprises driver and installing rack, and milling cutter rotates under the driving of driver, and milling cutter and driver all are fixedly arranged on knife rest by installing rack.
Home roll to be processed is installed on after the main shaft, forms before the wire casing, home roll to be processed is carried out turning.
Home roll to be processed is carried out home roll to be processed being carried out roughing before the turning.The present invention has following beneficial effect:
1. the processing method of slicer home roll of the present invention is simple, and is easy to operate, and process does not need to be installed, and only needs tool changing to get final product, and will foreshorten to process time below 1/3rd, increased substantially working (machining) efficiency.
2. the processing method of slicer home roll of the present invention not only can process the low-angle wire casing, and the shape of wire casing is easy to control, increased substantially machining accuracy, broken through the bottleneck that existing process technology is difficult to process the wire casing angle, be conducive to prolong the service life of line of cut and home roll, reduce cutting cost, cutting has great impetus to silicon wafer.

The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment, the processing method of slicer home roll provided by the invention may further comprise the steps:
Referring to Fig. 1, comprise lathe and home roll 20 to be processed.Lathe can be common numerical-control horizontal lathe, and it comprises main shaft and the knife rest 10 that is oppositely arranged.Knife rest 10 can be circular cutter holder, and in the present embodiment, knife rest 10 has 12 cutter spacing 11 altogether.Different from common lathe is that the knife rest 10 in the present embodiment is installed with milling mechanism 12.Milling mechanism 12 comprises milling cutter 120, driver 121 and installing rack 122.Milling cutter 120 is metal saw, and it comprises cutter hub 123 and is connected in a plurality of sawtooth 124 of cutter hub 123 outer rims.The shape of sawtooth 124 can be done respective design according to the shape of wire casing to be processed.Driver 121 is used for driving milling cutter 120 and rotates.Milling cutter 120 and driver 121 are fixedly arranged on knife rest 10 by installing rack 122.Installing rack 122 only occupies three cutter spacing 11 of knife rest 10.Remaining nine cutter spacing 11 can be installed other cutter on the knife rest 10.
Successively home roll to be processed 20 is carried out roughing and fine finishining.Particularly, adopt a kind of turning cutting tool that home roll to be processed 20 is carried out roughing after, need not again to be installed, can carry out the fine finishining of turning to home roll to be processed 20 after the tool changing.
Referring to Fig. 2, after fine finishining, still need not again to be installed, make milling mechanism 12 aim at home roll 20 to be processed and can begin the processing of wire casing.Particularly, make milling mechanism 12 aim at the first end 21 of home roll 20 to be processed, by the program of lathe is set, home roll to be processed 20 is rotated in a first direction, and along major axes orientation toward its second end 22 place's continuous movings; Keep knife rest 10 motionless this moment, and only the milling cutter 120 of milling mechanism 12 rotates along the second direction opposite with first direction under the driving of driver 121.Since between the sawtooth 124 of milling cutter 120 and home roll 20 surfaces to be processed to the effect of cutting, the formation wire casing 30 corresponding with sawtooth 124 shapes of milling cutter 120 in home roll to be processed 20 significantly improves machining accuracy and efficient easily.Under this programming, wire casing 30 is a continuous spiral groove.When laying line of cut formation gauze in the wire casing 30 of this structure, the tension force on the line of cut is dispersed, and can greatly reduce the friction between line of cut and the wire casing 30, prolongs the service life of line of cut and home roll.
Certainly, also can change the lathe programming, so that home roll 20 to be processed is when being rotated in a first direction, along major axes orientation toward its second end 22 place's intermittent movements, namely, a groove position aiming at home roll 20 surfaces to be processed when milling cutter 120 adds man-hour, and home roll 20 to be processed only is rotated in a first direction, and the movement along major axes orientation does not occur; Whenever milling cutter 120 is finished man-hour that adds of a groove position, home roll 20 to be processed moves to next groove position and processes; So repeatedly carry out, until be machined to last groove position at close the second end 22 places.Under this procedure, wire casing 30 comprises a plurality of coaxial cannelures.
The shape of the wire casing 30 of gained as shown in Figure 3, for U-shaped, it comprises the first side wall 31, the second sidewall 32 and diapire 33.The first side wall 31 is relative with the second sidewall 32.Diapire 33 is arc, and is connected between the first side wall 31 and the second sidewall 32.The angle that the first side wall 31 of wire casing 30 and the second sidewall are 32 is the 30-70 degree, preferably, under this processing mode, can be decreased to the 30-50 degree.Because the reducing of wire casing 30 angles, the surface at the home roll to be processed 20 of equal length can process more groove position, thereby can improve wiring density, reduces the silicon crystal cutting thickness.In addition, compared to existing V-type wire casing, U-shaped wire casing has the diapire 33 of arc, can avoid line of cut to be stuck in the bottom of wire casing 30, or reduce the friction between line of cut and the wire casing 30, prolongs the service life of line of cut and home roll, reduces cutting cost.
Adopt the processing method of slicer home roll of the present invention, can process the low-angle wire casing, and the shape of wire casing is easy to control, improved machining accuracy, broken through the bottleneck of the existing process technology processing line angle of the v-groove, and will foreshorten to 3 hours from existing 10 hours process time, and improve working (machining) efficiency, cutting has great impetus to silicon wafer; The shape of processing wire casing is easy to control, and is conducive to prolong the service life of line of cut and home roll, reduces cutting cost.
