The cutting machine tool comprises a base, and is characterized in that an aluminum frame and a stepping motor II are arranged on the base, the stepping motor II is provided with a two-dimension rotary table, a stepping motor I is arranged above the aluminum frame, lead screws driven by a stepping motor I are respectively arranged on sides of the aluminum frame, a diamond cutting micro-line is horizontally arranged among the lead screws, a flare angle control device is arranged on the diamond cutting micro-line correspondingly, and the flare angle control device consists of a vertical post and a photoelectric sensor on the vertical post.

Description

The little wire cutting machine tool of numerical control diamond

Technical field:

The utility model relates to a kind of lathe, more particularly, relates to a kind of cutting off machine of large scale semi-conducting material.

Background technology:

The cutting of existing large-size crystals, and what adopt is the multi-thread cutting of the free mortar of light, and cutting thickness is limited, efficient is low, though arbitrarily adjusting below 2 millimeters, but want processed complex, expensive mould; Therefore, only be fit to the cutting of silicon chip, be not suitable for special large-size crystals cutting, for example crystal-cut such as sodium iodide, calcirm-fluoride, cesium iodide.Another characteristics of above-mentioned crystal are easy cleavage, should not use the rigid cutting of equipment such as band saw, outer saw blade, and for example, if with band saw, cylindrical cutting machine, the width of 300 mm dia saw kerfs is more than 6 millimeters; And the price of these crystal is also relatively more expensive, and therefore the material of cutting decreases and also can not be ignored.Yet, the lathe of the special large-size crystals of existing cutting, general weight reaches several tons, and volume is big and heavy, moves difficulty.

Summary of the invention:

The utility model is exactly at the problems referred to above, overcomes the deficiency that prior art exists, and provides a kind of numerical control diamond little wire cutting machine tool; This cutting off machine can be controlled cutting thickness flexibly, raises the efficiency, otch is little, face shape is good, adopts light body structure, moves easily; Solve other cutting mode and cause the crystal cleavage, reduce the loss of material in the cutting process, and the profile heaviness, move difficulty, can not the on-the-spot problem of using.

For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises base, its structural feature is that base is provided with aluminium chassis and stepper motor II, have 2-d rotating platform on the stepper motor I I, the top of described aluminium chassis is provided with stepper motor I, the side of aluminium chassis is respectively equipped with the leading screw that is driven by stepper motor I, flatly be provided with the little line of diamond cut between the leading screw, be provided with the subtended angle control device corresponding to the little line of diamond cut, described subtended angle control device is to be made of the photoelectric sensor on column and the column.

The diameter of the little line of described diamond cut is less than 0.45mm.

The beneficial effects of the utility model:

The crystal-cut thickness of the little wire cutting machine tool of the utility model numerical control diamond can arbitrarily be adjusted, and only needs to adjust parameter and get final product on the panel of controller, does not need to make expensive mould.Owing to adopted the little line of diamond cut, cutting efficiency significantly improves, and the little line of diamond cut is flexible, has avoided the cleavage of crystal; And because the little linear diameter of diamond cut is below 0.45mm, so otch is below 0.5mm, and the crystal loss is very little; Cut the above crystal of 300 mm dias, flatness is less than 0.1mm, and face shape is good.In addition, the little wire cutting machine tool of the utility model numerical control diamond is an aluminium chassis, and in light weight, mobile easily, weight has only 300 kilograms.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the partial enlarged drawing of Fig. 1;

1 is that the little line of diamond cut, 2 is that leading screw, 3 is that controller, 4 is that stepper motor I, 5 is that subtended angle control device, 6 is that column, 7 is that 2-d rotating platform, 8 is that aluminium chassis, 9 is that stepper motor II, 10 is that base, 11 is a photoelectric sensor in the accompanying drawing.

The specific embodiment:

The utility model comprises base 10, base 10 is provided with aluminium chassis 8 and stepper motor II9, have 2-d rotating platform 7 on the stepper motor II9, the top of described aluminium chassis 8 is provided with stepper motor I4, the side of aluminium chassis 8 is respectively equipped with the leading screw 2 that is driven by stepper motor I4, flatly be provided with the little line 1 of diamond cut between the leading screw 2, be provided with subtended angle control device 5 corresponding to the little line 1 of diamond cut, described subtended angle control device 5 is to be made of the photoelectric sensor 11 on column 6 and the column 6.

Wherein, part can be purchased in photoelectric sensor 11 genus markets.

The little wire cutting machine tool of numerical control diamond of the present utility model also is furnished with the controller 3 that uses the PLC program control machine tool.

During use, on controller 3, adjust operational factor, stepper motor II9 drives 2-d rotating platform 7, make that crystalline material moves to the little line of diamond cut 1 below on the 2-d rotating platform 7, simultaneously, stepper motor I4 moves up and down by the little line 1 of leading screw 2 drive diamond cut and cuts crystalline material on the 2-d rotating platform 7.In cutting process, the contact wire of being cut crystal can change, and when just cutting, contact wire is shorter, and when the center, contact wire is elongated, and the angle of the little line 1 of diamond cut also can change, and cut surface shape is bent.In order to keep cutting uniformly little line subtended angle, cut surface shape is not bent, when when cutting, no matter how the geometry of crystalline material changes, under the effect of the photoelectric sensor 11 of subtended angle control device 5, be that the angle of the little line 1 of diamond cut is when changing, send signal by photoelectric sensor 11,, stepper motor I4 is out of service, make the little line 1 of diamond cut all keep a fixed shape, make cut surface shape intact.

Be with being appreciated that, more than about specific descriptions of the present utility model, only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
