The grinding wheel is a grinding tool, which consists of a tool bit and a matrix. During high-speed rotation, the bit portion of the grinding wheel contacts the workpiece, and the surface of the workpiece is ground by the abrasive inlaid in the surface of the grinding wheel, which is generally used for polishing, sizing, cutting and the like. In the field of ceramic processing, ceramic tile size processing is an indispensable procedure in the whole production process, and a required ceramic processing grinding wheel is an important guarantee for guaranteeing processing efficiency and qualification rate.
The ceramic processing grinding wheel is generally disc-shaped, wherein a connecting hole is arranged on the base body and is used for being connected with a grinding head flange. The tool bit is divided into integral type or split type according to the structure, and integral type tool bit is the ring form and fixes on the base member, and split type tool bit comprises a plurality of abrasive segments in succession, and each abrasive segment is fixed on the base member with annular distribution's form. The integrated tool bit has the advantage that the integrated tool bit is a complete circular ring, the risk of dropping the grinding block during grinding is reduced, but the disadvantage that dust or grinding dust accumulated in the integrated tool bit is difficult to discharge. The split type tool bit has the advantages of easy chip removal and short grinding life.
However, in either case, dust or dust is accumulated at the junction of the base and the bit due to centrifugal force when the grinding wheel rotates at high speed. Referring to fig. 1a, the junction of the existing basic body 100 'and the existing tool bit 200' is a right-angled corner from a cross-sectional view, where dust or abrasive dust is easily accumulated by centrifugal force of the grinding wheel. When dust or abrasive dust is excessively accumulated, the grinding effect and grinding efficiency of the grinding wheel are lowered, so that a worker has to stop the machine and clean the grinding wheel with a brush, lowering the production efficiency. Also, for some grinding wheels having two or more bits, referring to fig. 1b, each existing bit 200 'is arranged in a concentric ring-like manner, and gaps between adjacent existing bits 200' are particularly prone to dust or abrasive dust accumulation, and are difficult to clean even by manual cleaning.
In view of this, the present application proposes a ceramic grinding wheel, in which dust or abrasive dust accumulated at the junction of the tool bit 200 and the base 100 is discharged to the second surface 120 of the base 100 along the air flow hole 130 when the base 100 rotates at a high speed by providing the inclined air flow hole 130 on the base 100, thereby reducing the accumulation of dust or abrasive dust and improving the grinding effect of the grinding wheel.
Referring to fig. 2, the grinding wheel of the present application includes a base 100 and a first tool bit 200. The base body 100 is a main body structure of the grinding wheel, and is disc-shaped, and a connecting hole for connecting a rotating main shaft of a machine tool and a plurality of fixing bolt holes distributed in a circumferential array around the connecting hole are formed in the middle of the base body. Referring to fig. 3, the substrate 100 transitions from a first surface 110 to a second surface 120 along its thickness, the first surface 110 being a working surface adjacent to the workpiece and the second surface 120 facing away from the workpiece being a non-working surface.
The first tool bit 200 is annular and fixedly mounted to the first surface 110 of the base 100. The first cutter head 200 may be an integrated cutter head or a separate cutter head, and its outer wall surface is flat with the side surface of the base 100. The first tool bit 200 and the substrate 100 are fixed by adopting an adhesion manner, and the joint surface of the first tool bit 200 and the substrate 100 can be further provided with a concave-convex structure to increase the contact area of the first tool bit and the substrate, so that the adhesion strength is improved.
It should be noted that the base 100 is provided with an airflow hole 130. The first end 131 of the air flow hole 130 penetrates to the first surface 110 of the base 100, and the second end 132 of the air flow hole 130 penetrates to the second surface 120 of the base 100, which is a through hole. The first end 131 of the air flow hole 130 is connected to the inner sidewall surface of the first tool bit 200, so that dust or abrasive dust accumulated at the junction of the first tool bit 200 and the base 100 can easily enter the air flow hole 130. The second end 132 of the airflow hole 130 is an air outlet end, and the airflow direction of the second end forms an included angle θ with the airflow direction of the first surface 110 of the substrate 100, where the included angle θ is greater than 0 ° and less than 90 °.
Thus, when the base body 100 rotates at a high speed, dust or abrasive dust generated by grinding the first tool bit 200 first falls into the inner side of the first tool bit 200, and is accumulated at the junction of the first tool bit 200 and the base body 100 due to centrifugal force. Because the air flow hole 130 is connected to the inner wall surface of the first tool bit 200, and the air flow hole 130 is an inclined hole, an acute angle is formed between the air flow hole 130 and the air flow direction on the first surface 110, and dust or abrasive dust can be thrown into the air flow hole 130. Eventually, dust or swarf is discharged to the second surface of the substrate 100, i.e., the non-working surface of the substrate 100, along with the air flow holes 130, reducing the impact on the grinding work of the present grinding wheel.
Further, the number of the air flow holes 130 is at least two, so that the chip removal effect can be improved by arranging two or more air flow holes 130, and the number of the air flow holes 130 can be increased or decreased according to the size of the grinding wheel and the actual working condition. To reduce the shift in the center of gravity of the grinding wheel and to provide uniform chip removal, the individual air flow holes 130 are distributed in a circumferential array.
Specifically, the included angle θ ranges from 5 ° to 85 °, which avoids blocking caused by dust or abrasive dust accumulated in the airflow hole 130 due to too small included angle θ, or prevents dust or abrasive dust from entering the airflow hole 130 due to too large included angle θ.
Further, for the hole pattern of the airflow hole 130, in some embodiments, the airflow hole 130 is specifically a circular hole, the aperture range is 1 mm-100 mm, and the circular hole is adopted to facilitate processing and forming. In other embodiments, the airflow hole 130 is specifically a square hole, and the diagonal length ranges from 1mm to 100mm, so that the square hole can be more fit to the inner wall surface of the first tool bit 200, and thus dust or abrasive dust can more easily enter the airflow hole 130. It will be readily appreciated that other shapes of the airflow apertures 130 may be used to achieve the chip removal effect and will not be described in detail herein.
Further, for the way of opening the airflow hole 130, in some embodiments, the airflow hole 130 is a straight hole, so as to facilitate punching and opening. In other embodiments, the airflow aperture 130 is arcuate and follows the direction of the airflow to reduce the impact on the airflow and to facilitate the removal of dust or debris from the airflow aperture 130. Specifically, the arcuate airflow aperture 130 creates an arcuate projection along the axis of the base 100, with the center of the arcuate projection being located within the outer contour of the first tool tip 200. Preferably, the center of the arc-shaped projection is located on the axis of rotation of the base 100 so as to conform as closely as possible to the shape profile of the first tool tip 200.
Further, in some embodiments, the ceramic working grinding wheel further comprises a second tool bit 300. The second tool tip 300 is generally made of a different material from the first tool tip 200, so that two grinding effects can be obtained simultaneously during the grinding process. The second tool bit 300 is annular and fixedly mounted on the first surface 110 of the base 100, and is disposed inside the first tool bit 200 and coaxially disposed. A gap 400 is reserved between the second tool bit 300 and the first tool bit 200, and the airflow hole 130 is arranged in the gap 400.
For the specific arrangement of the airflow holes 130, the present application proposes the following embodiments.
