Description

Grinding wheel with chip drain

The present invention relates to a grinding wheel, and more particularly to a grinding wheel having a chip groove.

In general, when a workpiece of a hard and brittle material such as glass, quartz, twin, sapphire or ceramic is polished, it is necessary to polish the workpiece with a grinding wheel having a high wear body such as a diamond grinding wheel.

Conventional grinding wheels generally include a wheel base and a plurality of high wear bodies spaced apart from the upper surface of the wheel base. The wheel base is mounted on a rotating mechanism, and the surface of the workpiece is ground by the plurality of high wear bodies.

In the process of grinding the workpiece by the grinding wheel, the powder is continuously generated, and the conventional grinding does not have the chip discharging structure, so the powder will be accumulated on the upper surface of the grinding wheel. At the beginning of the new use of the grinding wheel, since the high wear-resistant body has a sufficient height, the accumulated dust is not enough to adversely affect the grinding quality. However, as the use time is long, the high wear-resistant body gradually wears, and the accumulated dust is increasing, and gradually approaches the height of high wear resistance or even exceeds the height of the high wear-resistant body. During the grinding process, the accumulated dust will scrape the workpiece, causing the broken edges and damage of the workpiece.

The invention provides a grinding wheel with a chip drain which can discharge the dust generated during the grinding process.

According to an aspect of the present invention, a grinding wheel having a chip groove is provided, comprising: a wheel base having an upper surface and a lower surface at opposite sides, and an outer wall and an inner wall at opposite sides, a wheel shape The upper surface of the pedestal is provided with a plurality of accommodating grooves spaced apart from the outer wall thereof toward the inner wall; a plurality of high wear-resistant bodies respectively disposed in the accommodating grooves; and a plurality of chip-groove grooves spaced apart from the wheel shape The upper surface of the base is respectively interposed between the high wear bodies and communicates with the outer wall and the inner wall of the wheel base.

According to an embodiment of the present invention, each of the high wear-resistant bodies and the flutes are spirally extended from the outer wall of the wheel-shaped base toward the inner wall.

According to an embodiment of the invention, the wheel base is a metal wheel base.

According to an embodiment of the invention, the high wear resistant system is selected from one or more of artificial or natural diamond micropowder, or cubic boron nitride.

According to the grinding wheel with the chip removing groove according to the present invention, according to the chip discharging groove, the dust generated during the grinding of the workpiece by the grinding wheel can be immediately discharged, so as to prevent the powder from accumulating on the upper surface of the wheel base. To avoid accidental scratching of the workpiece by the powder, and to ensure the quality of the grinding.

The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of embodiments with reference to the drawings.

Referring to FIGS. 1 to 5 , a grinding wheel having a chip groove according to an embodiment of the present invention includes a wheel base 100 , a plurality of high wear bodies 200 and a plurality of chip grooves 300 .

The wheel base 100 is made of a metal such as aluminum. The wheel base 100 has an upper surface 110 and a lower surface 120 opposite to each other, and an outer wall 130 and an inner wall 140 located opposite to each other. The upper surface 110 of the wheeled base 100 is spaced apart from the outer wall 130 toward the inner wall 140. The accommodating groove 150 is spirally extended. The wheel base 100 is mounted on a rotating mechanism (not shown), and the spiral direction of the receiving groove 150 coincides with the rotating direction of the wheel base 100.

The plurality of high wear-resistant bodies 200 are respectively disposed in the respective receiving grooves 150 of the wheel-shaped base 100. Therefore, the high-wearing body 200 is also spirally extended from the outer wall 130 of the wheel-shaped base 100 toward the inner wall 140. . The high abrasion resistance system is selected from one or more of artificial or natural diamond micropowder, or cubic boron nitride.

The plurality of chip flutes 300 are spaced apart from the upper surface 110 of the wheel base 100 and are respectively interposed between the high wear bodies 200 and communicate with the outer wall 130 and the inner wall 140 of the wheel base 100. Each of the chip flutes 300 is aligned with the direction of each of the high wear-resistant bodies 200, and is also spirally extended from the outer wall 130 of the wheel-shaped base 100 toward the inner wall 140.

In use, the wheel base 100 is mounted on a rotating mechanism, and the surface of the workpiece is ground by a plurality of high wear bodies 200. The dust generated during the grinding process can be discharged from the chip evacuation groove 300.

According to the grinding wheel with the chip removing groove according to an embodiment of the present invention, according to the chip discharging groove, the dust generated during the grinding of the workpiece by the grinding wheel can be immediately discharged, so as to prevent the powder from being accumulated in the wheel base. The upper surface of the seat can prevent the powder from accidentally scratching the workpiece and ensure the quality of the grinding.

Although the present invention is disclosed in the above embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various changes and retouchings without departing from the spirit and scope of the present invention. The scope of protection is subject to the definition of the scope of the patent application attached.
