Diamond line test method

The invention relates to a diamond line testing method.

At present, the industry generally uses a diamond wire cutter to cut silicon wafers, sapphire crystal rods, and the like. The industry uses diamond wire cutting machines for direct cutting tests on diamond line tests. Generally, a roll of diamond wire has a length of about 3 to 7 kilometers. First, the diamond wire fixed on the diamond wire cutter has a linear velocity moving in the horizontal direction; and the object to be tested, such as a glass rod, is fixed on the diamond wire cutter. The center line of the glass rod is horizontally disposed; the diamond line is moved toward the glass rod in the vertical direction and perpendicular to the center line direction of the glass rod, and passes through the glass rod for cutting action. When cutting a cylindrical glass rod having a diameter of 4 inches, cutting a cylindrical sheet requires the length of the worn diamond wire to be 1 meter. Then test the life of a roll of diamond wire to cut 3000 ~ 7000 pieces of 4 inch diameter glass rod sheet to confirm the life of the diamond line and the quality of the cut surface. Since the diamond wire cutter test often takes a considerable amount of time and the entire roll of diamond wire and multiple objects to be tested, it is an uneconomical practice.

In view of this, it is necessary to provide a cost-saving diamond line test method.

A diamond wire testing method comprising the steps of: providing a test object, aligning a predetermined length of tensioned diamond wire with a test object; predetermining a cutting depth; rotating the test object and gradually approaching the segment of the diamond wire to cut the test object Test object; according to diamond Whether the line cuts into the test object can reach the predetermined depth to obtain the test result of the diamond line.

Compared with the prior art, according to the above method, a diamond wire can be used for the cutting action without the need of a whole roll of diamond wire, which can save the consumption of the whole diamond wire when testing the quality of the diamond wire.

The test object 200 is a cylindrical glass rod whose center line is parallel to the bearing surface 111 and the second rail 133.

The test method steps for Diamond Line 300 are as follows:

S1. A test object 200 is provided that aligns a length of diamond wire 300 of predetermined length and tension with the test object 200.

The cylindrical glass rod is fixed to a rotary motor 150 whose center line is parallel to the bearing surface 111 of the base 110. The two ends of the diamond wire 300 are respectively fixed on the two diamond wire fixing portions 175. The portion of the diamond wire 300 between the two diamond wire fixing portions 175 is received in the limiting groove 1740 of the two guide wheels 174. The diamond line 300 between the two guide wheels 174 in the cutting section is located on the side of the notch 1712 near the edge of the fixing plate 171, and the tension of the diamond wire 300 in the cutting section is 40 Newtons. .

The setting direction of the cutting section of the diamond wire 300 is aligned with the surface to be cut of the test object 200. A first drive motor (not shown) and a second drive motor (not shown) are opened to adjust the horizontal position of the test object 200 such that the surface to be cut is aligned with the cutting segment of the diamond wire 300. The third drive motor 138 is driven to bring the cutting segment of the diamond wire 300 into proximity to the test object 200.

S2: A cutting depth is predetermined.

In the present embodiment, the predetermined cutting depth is a depth cut along the diameter of the glass rod. The predetermined depth of cut is set according to the size of the selected glass rod and the quality requirements of the diamond line. The shorter the diameter of the glass rod or the higher the quality requirement of the diamond thread, the greater the predetermined cutting depth. For example, if a glass rod having a diameter of 4 inches is cut, the predetermined cutting depth may be set according to the ratio of the area of the cut glass rod to the cross-sectional area of the entire glass rod, for example, 8%-15%. As in the prior art, a roll of diamond wire is about 3 to 7 kilometers in length, and a cylindrical piece with a diameter of 4 inches is required to wear a diamond wire of 1 meter. The length of life of a roll of diamond wire needs to be cut by 3000 to 7000 pieces. A 4 inch glass bar sheet is used to confirm the quality of the life of the diamond line 300 and the quality of the cut surface. However, if the diamond wire 300 test method proposed in the present embodiment is used, the life of the whole diamond wire 300 and the cutting quality can be confirmed by using a glass rod having a depth corresponding to 8% to 15% of the sheet area.

At the diamond wire cutter 100, the diamond wire 300 is cut to a predetermined depth of cut of the test article 200, and then stops when the diamond wire 300 cuts the test article 200 to a predetermined depth.

S3: The test object 200 is rotated and gradually approached to the diamond line 300 to cut the test object 200. If the diamond wire 300 has been cut before the test article 200 has reached the predetermined depth, the diamond wire 300 is deemed to be unqualified. If the diamond line 300 is cut into the test object 200 If the predetermined depth is still not broken, S4 is performed.

The rotating motor 150 is turned on to rotate the test object 200, and the outer edge of the test object 200 has a linear velocity of 700-1200 m/min to open the third driving motor 138. The diamond wire fixing module 170 is driven by the third driving motor 138. The lower portion moves along the third rail 135 and moves in the direction of the vertical bearing surface 111 to cut the test object 200, that is, the glass rod. The test article 200 then enters the notch 1712 during rotation and is cut by the cutting segment of the diamond wire 300 as it enters the notch 1712. Since the diamond wire 300 is in the cutting section and the portion in contact with the glass rod is cut, the wear rate of the diamond wire 300 here is relatively fast, so that the quality condition of the diamond wire 300 and the cutting parameters can be quickly evaluated. It can be understood that the test object 200 can be first disposed in the notch 1712. When the cutting motion is performed, the diamond wire 300 disposed under the test object 200 is moved toward the center line of the glass bar, that is, upward. Under the rotation of the test object 200, the cutting action is also performed.

S4. Measure the diameter of the diamond wire and compare the measured diamond wire diameter value with a predetermined value to obtain a test result.

The diameter value obtained by measuring the cutting section of the diamond wire 300 after the cutting operation is less than a predetermined value. In the embodiment, when the predetermined value is 0.19 mm, it is determined that the diamond wire 300 of the roll or the diamond wire of the batch or the model is The defective or unqualified product does not meet the demand; when the measured diameter value is greater than or equal to the predetermined value of 0.19mm, it is determined that the diamond line 300 or the batch or the diamond line of this model is a good or qualified product, which is in conformity with demand.

According to the above method, the quality of the diamond wire 300 can be quickly tested, saving the test time while saving the length of use of the diamond wire 300. In addition, the glass rod in the specific embodiment may be selected from ceramics, metals, plastics, wood, etc. according to actual needs. The shape can be selected from bars, plates, blocks or irregular shapes according to actual needs. Specific numerical parameters can be modified and changed according to different needs.

Furthermore, the order of the S1 and S2 steps can be interchanged.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
