How to reasonably choose the ultra-thin diamond cutting piece and the correct use method

First, how to choose ultra-thin diamond cutting sheet

How to choose the rational choice of ultra-thin diamond cutting pieces, the correct use of ultra-thin diamond cutting pieces, choose the ultra-thin diamond cutting piece in the process of cutting glass tubes, precious stones should pay attention to matters:

Take appropriate ultra-thin diamond cutting blades, suitable fixtures, fixed ultra-thin cutting machine, different materials use different ultra-thin diamond cutting blades, in order to achieve the most perfect cutting, it is recommended to be reasonable under the advice of engineers. Select ultra-thin cutting sheet,

Second, the correct use of ultra-thin diamond cutting piece:

Ultra-thin diamond cutting discs are mainly used for precision cutting and cutting. Deep cutting feed grinding method is generally used. It has the characteristics of large depth of grinding, small feed rate, large contact area between grinding wheel and workpiece, narrow kerf, high metal removal rate, high grinding precision, good surface quality, and high material utilization rate. The general rule is as follows:

1). Integral type ultra-thin diamond cutting sheet is thin (more than 0.5mm), small outside diameter (20-100mm), fine grain size, high precision in size and shape, light weight, generally used under high speed conditions. The general speed is 5000-40000 rpm.

2). The matrix type ultra-thin diamond cutting discs are mostly thick (0.5-2mm), large in diameter (100-200mm), coarse in granularity, and low in precision. They are generally used under conditions of low speed and large depth of cut. The general speed is 3000-10000 rpm.

3). Ultra-thin diamond cutting sheets use finer grain sizes, and generally the thinner the thickness, the smaller the abrasive grain size will be, and the better the machining surface quality. However, the finer the abrasive grain size, the lower the cutting sharpness, and the correspondingly reduced feed rate to suit the abrasive grain size machinability.

4). The cutting depth of the ultra-thin diamond cutting sheet is generally determined by the user according to the cutting part, and the cutting is mostly performed by a slow-feed grinding process, and the depth is once cut. Since the cutting wheel is thin and the cutting conditions are poor (mostly three surfaces are in contact with the workpiece), it is difficult to dissipate heat. Therefore, the cutting area must be cooled (flow rate, pressure).

5). When the ultra-thin diamond cutting blade appears on the machine at the user's point of use when the machine appears to cut or the workpiece breaks, it is recommended to increase the cutting speed or reduce the feed; when a certain period of time occurs after the cut does not move or collapse It is recommended that the surface of the grinding wheel be sharpened with a suitable size of oil stone to adjust its sharpness.

6). The surface quality and cutting performance of the workpiece are mainly related to the abrasive grain size of the ultra-thin diamond cutting blade. The finer the grain size, the better the surface finish. At the same time with the workpiece material, hardness, cutting amount, machine conditions, processing requirements and other factors also have a relationship.

7) Decathlon® ultra-thin diamond cutting blades have generally been shaped and sharpened before leaving the factory and can be used by the user. If the user needs further reshaping, it is recommended to use green silicon carbide or white corundum stone, particle size than the cutting wheel size 1-2 coarse; if the user needs to open the edge or use a section of the edge, it is recommended to use green silicon carbide or white corundum Whetstone, particle size than the cutting wheel size 1-2 fine or the same number can be.

8) The amount of cutting is generally related to the material being processed, hardness, precision, processing requirements, etc. It is recommended that it should be used under the original user's conditions when it is used for the first time. Do not change the cutting amount easily.

9) User conditions are also the main factors affecting the cutting performance. In particular, the spindle axial runout, radial runout, flange parallelism, and dynamic balance accuracy all directly affect the cutting accuracy of the cutting wheel.

Third, de Carter ultra-thin diamond cutting sheet types:

1. According to the type of binder:

There are two types of metal binder (code M) and resin binder (code B)

2. According to the structural form to divide:

There are two types of integral type (1A8) and base type (1A1, 1A1R, 1B1, 14A1, 3A1, 4B1, etc.), and the overall thickness is thin, which is suitable for processing with narrow slits and small depth of cut. The matrix type has good rigidity and is suitable for processing with large depth of cut and high dimensional accuracy.

Integral cutting wheel means that the grinding wheel is made of the same kind of material as a whole. Thin, high precision, used for high precision, small cut depth cutting and cutting. The general speed is 5000-40000 rpm.

The base type cutting wheel means that the outer ring of the grinding wheel is an abrasive working layer, and the center part is a high-strength and high-rigidity metal material, also called an outer ring type cutting wheel. This type of grinding wheel is generally slightly thick, has good rigidity, and has a low rotation speed. Rotation speed is 3000-10000 rpm, used for cutting and cutting of large depth of cut at low speed.

3. Press the working layer with or without sink:

It can be divided into sink type (1A8/2, 1A1/5, 1A1R/5) and without sink type (1A8/1, 1A1/3, 1A1R/4). With sink type is conducive to chip evacuation and cooling, suitable for processing with fast cutting speed, deep cutting and easy heating

4. According to the processing technology to divide: Sintering, electroplating

Fourth, the use of de Carter ® cutting sheet Note:

1. Please check carefully before installing the cutting wheel. If there is any gap or other damage, please stop using it.

2. When the cutting wheel is marked with the direction of rotation, it must be consistent with the direction of rotation of the machine. On the contrary, the cutting is not sharp and it is difficult to exert the performance of the cutting wheel.

3. Please do not use non-compliant cutting wheel.

4. If any abnormality is found during cutting, stop the machine immediately and check the cause.

5. When the cutting is not sharp, it is necessary to trim the grinding wheel. If you continue to use it, it may cause overheating and overloading to break the grinding wheel.

6. In the rotation of the grinding wheel, it is forbidden to cut by hand, and it is impossible to touch the sand by hand and body.

7. It is strictly prohibited to use the cutting wheel for operations other than grooving or cutting, so as to avoid abnormalities due to uneven force.

The correct choice and reasonable use can make the work efficiency of Dekate® ultra-thin diamond cutting sheet increase many times, and it can effectively protect the super thin sheet and achieve a multiplier effect.
