Description

TECHNICAL FIELD

[0001] The utility model relates to diamond grinding wheel manufacturing field, concretely relates to a diamond metal bond grinding wheel. BACKGROUND

[0002] Compared with ordinary ceramic bond grinding wheels, diamond metal bond grinding wheels have remarkable wear resistance. This characteristic makes them perform well in the grinding of many high-strength and high-hardness materials. As the hardest natural substance in nature, diamond gives this grinding wheel extremely strong grinding ability. However, this grinding wheel also has some defects in the grinding process.

[0003] When diamond metal bond grinding wheels are grinding, if the feed amount is large, a dull sound will be produced. This sound is caused by the hardness of the metal bond and the intense friction between the grinding wheel and the workpiece during the grinding process. When the grinding wheel contacts the workpiece, the hardness of the metal bond causes the friction force to increase, thus producing this unique sound. This sound is not only an auditory experience, but also reflects the friction state and working state of the grinding wheel during the grinding process.

[0004] During the grinding process of diamond metal bond grinding wheels, due to the hard nature of the metal bond itself, the grinding is similar to the mutual friction between two metal materials. This friction not only produces a large amount of heat, but also causes wear on the surface of the grinding wheel and the workpiece. Therefore, when using this grinding wheel for grinding, special attention should be paid to controlling the feed amount and grinding speed to avoid excessive friction and wear. At the same time, appropriate cooling liquid should also be selected to effectively control the temperature during the grinding process, so as to prolong the service life of the grinding wheel and improve the grinding efficiency.

[0005] The high wear resistance and strong grinding ability of diamond metal bond grinding wheels make them have irreplaceable advantages in high-precision and high-surface-quality grinding processes. For example, in the fields of aerospace, automobile manufacturing, precision machinery, etc., the requirements for material surface quality and grinding efficiency are extremely high, and diamond metal bond grinding wheels are widely used due to their excellent grinding performance. However, the high cost and specific use conditions of this grinding wheel also limit its popularity in some low-cost or ordinary grinding applications.

[0006] Diamond metal bond grinding wheels, with their outstanding wear resistance and high-precision grinding ability, play an important role in many high-demand processing fields. However, attention should be paid to controlling the grinding parameters and selecting appropriate cooling methods during use to fully utilize their advantages and prolong their service life. Through reasonable design, the efficiency and quality of the grinding process can be significantly improved. SUMMARY

[0020] For the purpose, technical scheme and advantages of the utility model to be clearer and more obvious, the following through the drawing and example, the utility model is further described in detail. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following structure, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] In the description of the utility model, it should be pointed out that the terms "upper", "lower", "inner", "outer", "top / bottom end" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, "first", "second" are for the purpose of description only and cannot be understood as indicating or implying relative importance.

[0022] As Figure 1 The diamond metal bond grinding wheel shown in the figure includes a grinding wheel base body 100, and the grinding wheel base body 100 is a metal material base body. Preferably, the grinding wheel base body is a steel grinding wheel base body, a cast iron grinding wheel base body or an aluminum alloy grinding wheel base body.

[0023] A rotating shaft mounting hole 101 is formed in the center of the grinding wheel base body 100, and the grinding wheel base body 100 is mounted on the rotating shaft (not shown in the figure) of the external rotating mechanism through the rotating shaft mounting hole 101.

[0024] An abrasive ring 200 is arranged at the edge of the grinding wheel base body 100, and the abrasive ring 200 is formed by fixing diamond powder sintering through a metal binder. The metal binder is a bronze binder, a cobalt-based alloy binder, a nickel-based alloy binder, an iron-based alloy binder or a copper-based alloy binder.

[0025] A plurality of filling grooves or filling cavities 201 are equidistantly formed on the abrasive ring 200.

[0026] Resin material 300 is filled in the filling grooves or filling cavities 201. The width of the abrasive ring 200 is less than the width of the grinding wheel base body 100.

[0027] The friction of the diamond metal bond grinding wheel is reduced by filling the resin material 300. The noise is reduced while avoiding excessive friction and wear.

[0028] Due to the characteristics of the resin material, the metal binder powder and the diamond powder need to be cold-pressed into a metal grinding wheel cylinder in a special mold before sintering the metal grinding wheel.

[0029] During the feeding process, multi-layer packaging is required,

[0030] First, add one layer of calcium carbonate powder, then place a metal grinding wheel cylinder and add more calcium carbonate powder. Repeat this process for multiple layers. The sintering operation is the same as the conventional method for making grinding wheels with metal binders.

[0031] After the grinding wheel is sintered, the calcium carbonate is pulverized. Due to the high-temperature sintering of the metal, the matrix deforms. Before resin powder molding, the matrix needs to be finely trimmed. Grooving and resin powder molding are then carried out according to the resin mold. After demolding, normal machining and grinding are performed to produce the final product.

[0032] The above shows and describes the basic principles, main features, and advantages of this utility model.

[0033] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of this utility model as defined by the appended claims and their equivalents.
