Problems solved by technology

The existing technology mainly adopts the method of directly casting grinding fluid for cooling. It is difficult for the grinding fluid to inject into the grinding surface where the grinding wheel and the workpiece are in contact. easy to burn
At the same time, modern production has higher and higher requirements for grinding efficiency. Increasing the rotational speed (linear speed) of the grinding wheel and increasing the grinding depth are the inevitable methods to improve the grinding efficiency, which will inevitably further lead to an increase in the grinding temperature and affect Wheel life

Embodiment 1

[0032] Such as Figure 1 to Figure 5 As shown, a face diamond grinding wheel provided with a cooling channel includes a grinding wheel base 1 and a diamond agglomerate 2 . Among them, the diamond agglomerate 2 refers to a block with a certain shape formed by bonding the diamond abrasives together with a binder, and the end face diamond grinding wheel refers to a grinding wheel formed by fixing the diamond agglomerate to the working surface of the grinding wheel base 1 .

[0033] Specifically, an installation groove 4 is opened on the working surface of the grinding wheel base 1 , and the diamond agglomerate 2 is located in the installation groove 4 . Preferably, the installation groove 4 is set as an annular structure, and at the same time, the diamond agglomerates 2 are bonded and fixed in the installation groove 4 at intervals and evenly, that is to say, the diamond agglomerates 2 are provided with multiple pieces at intervals, and the diamond agglomerates 2 are arranged at...

Embodiment 2

[0039] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0040] The diamond agglomerates 2 are metal bond diamond agglomerates, and 16 diamond agglomerates 2 are bonded and fixed in the installation groove 4, and the adjacent diamond agglomerates 2 are equally spaced.

[0041] A total of 16 introduction holes 7 are provided on the grinding wheel base 1, and three transition grooves 10 are provided on each diamond agglomerate 2. Correspondingly, three cooling grooves 5 are provided corresponding to the transition grooves 10 below each diamond agglomerate 2. The center of the liquid outlet 9 of the inlet hole is aligned with the cooling groove 5 below the diamond agglomerate 2 and in the middle, that is, the center of the liquid outlet 9 of the inlet hole is aligned with the transition groove 10 in the middle. At the same time, three cooling holes 6 are opened on each diamond agglomerate 2 . To sum up, there is a one-to-one corr...

Embodiment 3

[0044] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0045] The diamond agglomerates 2 are metal bond diamond agglomerates, 14 diamond agglomerates 2 are bonded and fixed in the installation groove 4, and the adjacent diamond agglomerates 2 are equally spaced.

[0046] A total of 28 introduction holes 7 are provided on the grinding wheel base 1, and 4 cooling holes 6 are provided on each diamond agglomerate 2. Correspondingly, 4 transition grooves 10 are provided on each diamond agglomerate 2, and each diamond agglomerate 2. Corresponding to the transition groove 10, four cooling grooves 5 are arranged below. That is to say, each diamond agglomerate 2 corresponds to two introduction holes 7 , that is, each diamond agglomerate 2 has a non-one-to-one correspondence with the introduction holes 7 , and the number of cooling holes 6 is greater than the number of introduction holes 7 .

[0047] Specifically, the four cooling groov...

Abstract

The invention relates to an end face diamond grinding wheel with a cooling channel, and belongs to the technical field of end face diamond grinding wheels. The end face diamond grinding wheel comprises a grinding wheel base body and a diamond block, a mounting groove is formed in the working face of the grinding wheel base body, and a guide-in groove is formed in the end face opposite to the working face of the grinding wheel base body; the diamond block is installed in the mounting groove, and the diamond block is provided with a cooling hole which penetrates through the interior of the diamond block and is in communication with the guide-in groove; and grinding fluid is sequentially injected into the grinding wheel base body and the diamond block through the guide-in groove and is finally discharged through the cooling hole so as to reduce the grinding temperature of the working face. According to the end face diamond grinding wheel, the cooling channel is formed through the guide-in groove, a guide-in hole, a cooling groove, a transition groove and the cooling hole, the grinding fluid directly reaches a working area to reduce the grinding temperature, the service life of the grinding wheel can be prolonged, the cooling effect is remarkable, meanwhile, the grinding fluid plays a role in flushing abrasive dust, the abrasive dust is prevented from blocking the grinding wheel base body, and the grinding efficiency and the grinding quality are improved.

Description

technical field [0001] The invention belongs to the technical field of end-face diamond grinding wheels, and in particular relates to an end-face diamond grinding wheel provided with cooling passages. Background technique [0002] The end diamond grinding wheel refers to the grinding wheel formed by fixing diamond agglomerates to the end surface of the grinding wheel base. According to different binders, diamond agglomerates mainly include metal bond agglomerates, resin bond agglomerates and vitrified bond agglomerates. [0003] At present, the face diamond grinding wheel is widely used in the surface grinding of various hard and brittle materials. During grinding, the contact area between the end face diamond grinding wheel and the workpiece is large, the heat generation is high, and the grinding temperature is high. Therefore, it is generally necessary to use grinding fluid for cooling. The existing technology mainly adopts the method of directly casting grinding fluid f...
