Embodiment 1

[0022] Such as figure 2 As shown, a diamond grinding head includes a connecting rod part 1, a grinding head base body 2, a brazing material 3, diamond abrasive grains 4 and a spiral groove 5. The grinding head base 2 of the diamond grinding head is directly connected with the connecting rod part 1 as a whole. The surface of the base body 2 of the grinding head is fixed with diamond abrasive grains 4 by brazing; the diamond grinding layer on the surface of the base body 2 of the grinding head is provided with multiple spiral grooves 5 by laser. The base body 2 of the grinding head is conical.

[0023] The preparation process is as follows: weigh 100g of thermoplastic resin adhesive and ethanol diluent according to the mass ratio of 5:1, mix well, apply the mixture evenly on the surface of grinding head base 2, and let it stand for 15 minutes. Roll the treated grinding head substrate 2 in the nickel-based brazing material granules to form the nickel-based brazing material 3 b...

Abstract

The invention relates to a diamond grinding head and a preparation technology thereof. The diamond grinding head comprises a grinding head part and a connecting rod part, and a diamond grinding layeris fixed to the surface of the grinding head part in a brazed mode; and a plurality of spiral grooves are formed in the diamond grinding layer on the surface of the grinding head part through a laser.The preparation technology comprises the following steps that first a brazing material bonding layer with diamond abrasive grains is prepared on the surface of a grinding head part base body in a brazed mode, then the surface of the brazing material bonding layer with the diamond abrasive grains is ablated through a laser beam according to the set path, and the parts of ablated diamond abrasive grains and brazing material particles fall off to form the spiral grooves. According to the diamond grinding head and the preparation technology thereof, on the basis of significantly increasing bonding force between the diamond abrasive grains and the base body and by forming the spiral grooves in the surface of the diamond grinding head, chippings can be effectively discharged in time, the easy blockage phenomenon is effectively avoided, the grinding efficiency is improved, abrasion and working noise of the grinding head are reduced, the using cost of the grinding head is reduced, and the diamond grinding head with the chipping discharging function can work under the conditions of the higher rotational speed and grinding quantity.

Description

technical field [0001] The invention belongs to a diamond grinding head, in particular to a diamond grinding head with chip removal function through laser slotting and its preparation. Background technique [0002] Grinding heads can be divided into ceramic grinding heads, rubber grinding heads, emery cloth grinding heads, diamond grinding heads, etc. according to different abrasive materials. Compared with other grinding heads, diamond grinding heads have the advantages of small wear, long service life, high grinding efficiency, and good processing quality. Due to the advantages of high safety, it is widely used in stone carving, glass processing, jade processing and other precision processing fields. However, the existing ordinary sintered diamond grinding head is not sharp enough, and the electroplated diamond grinding head has a low service life due to insufficient bonding force. Under grinding conditions, it is easy to cause debris blockage, which will lead to wear of ...
