Problems solved by technology

The grinding wheel prepared by this method can enhance the holding force of the grinding wheel to the abrasive grains, improve the service life and grinding efficiency of the grinding wheel, but since the abrasive grains are randomly pressed into the blind hole, the shape of the top surface of each abrasive grain is random, which affects the precision of the machined surface; at the same time, the depth of the abrasive grains pressed into the blind hole is also inconsistent, so there is a large difference in the edge height of the sharpening edge, which greatly reduces the number of effective sharpening edges of the grinding wheel during grinding. Processing efficiency

Embodiment Construction

[0024] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings.

[0025] see Figure 1 to Figure 5 , a CVD diamond grinding wheel with an ordered surface microstructure, is characterized in that: the grinding wheel is composed of a hub 1, a diamond film 2, a large number of micro-grinding units 3 and microgrooves 4; a layer is deposited on the outer circumference of the hub 1 Diamond film 2; a large number of microgrooves 4 are processed on the outer peripheral surface of the diamond film, and the grinding unit 3 is between two adjacent microgrooves 4. At the same time, the microgrooves 4 and the grinding units 3 are arranged in a staggered order; all The top surfaces of the grinding units 3 are all waist-shaped 12 . When the grinding wheel grinds the workpiece 11, the grinding unit 3 undertakes the work of cutting the surface 13 of the workpiece, and the micro groove 4 mainly plays the role of chip holding and l...

Abstract

The invention discloses a CVD diamond grinding wheel with an ordered micro-structured surface and a making method thereof. The grinding wheel is characterized in that a layer of diamond film is deposited on the outer circumferential face of a grinding wheel hub, a large number of staggered in-order micro grinding units are machined on the whole outer circumferential face of the diamond film, and the top ends of the grinding units are in kidney shapes. The making method is characterized in that through the chemical vapor deposition that is CVD, the diamond film is deposited on the outer circumference face of the grinding wheel hub, a pulse laser beam is adopted to machine the large number of micro grooves with the same geometric dimensioning in the outer circumference face of the whole diamond film, and the large number of micro grinding units are formed; the grinding units are arranged in a staggered and in-order manner, the top face of each grinding unit is in a kidney shape, according to the grinding wheel, the effective sharpening number of the grinding wheel during grinding can be improved, the chip formation efficiency and the surface material removal rate are improved, the cutting performance is improved, the surface machining quality and the cutting efficiency can be improved, the holding force of the grinding wheel hub to the grinding units can be increased, and the service life of the grinding wheel can be obviously prolonged.

Description

technical field [0001] The invention relates to a diamond grinding wheel and a preparation method thereof, in particular to a CVD diamond grinding wheel with an ordered microstructured surface and a preparation method thereof. Background technique [0002] Grinding is an important part of mechanical processing. It has the characteristics of high processing precision and good surface quality. As a bonded abrasive tool with diamond as abrasive, diamond grinding wheel is widely used in grinding. The traditional diamond grinding wheel uses a bonding agent to randomly bond the abrasive on the working surface of the grinding wheel. The abrasive grains are arranged irregularly. The geometric shape and size of each diamond abrasive grain are inconsistent, and the contact area between the grinding wheel and the workpiece is large. The height is low, the chip space is small, the chip removal performance is poor, and the grinding wheel is easy to block, which intensifies the generation...
