Embodiment 1

[0015] Such as figure 1 with figure 2 As shown, the metal-bonded spider web-shaped plane grinding wheel includes three parts: a spider web-shaped working layer 1 , a transition layer 2 and a metal matrix 3 . The spider web-shaped working layer is composed of cutting entities 4 and gaps 5 distributed along the radial and circumferential directions. In the radial direction, the cutting entities are distributed concentrically from the center of the grinding wheel working layer plane to the outside. The thickness of each cutting entity is 0.5 mm, two The distance between cutting entities is 0.05mm; in the circumferential direction, the cutting entities are radiated from the center of the working layer of the grinding wheel to the outer diameter of the plane. The thickness of each cutting entity is 0.5mm, and the distance between two cutting entities is 0.05mm; The depth in the axial direction is 0.05mm; at the outer diameter circumference side of the working level, the thickness...

Abstract

The invention relates to a metal bond-containing arachnoid plane diamond grinding wheel and a 3D printing production process thereof, and belongs to the field of machining. According to the invention, an arachnoid working layer is composed of solids and gaps in a manner of being distributed on the working surface of the working layer along a radial direction and a peripheral direction, directly produced on a transition layer by virtue of a laser sintering 3D printing technology, and form the integrated plane diamond grinding wheel with the transition layer and a metal matrix. A precise arachnoid structure is realized on the working surface of the plane grinding wheel by virtue of 3D printing, the gaps are provided, and intermittent grinding is realized; the heat dissipation and cooling effects can be effectively improved; the thermal damages of grinding machining are reduced and the grinding efficiency is improved; and the problem of blockage of the grinding wheel can be effectively solved.

Description

technical field [0001] The invention mainly belongs to the field of mechanical processing, and in particular relates to a metal-bonded spider web-like plane diamond grinding wheel and a 3D printing manufacturing process thereof. Background technique [0002] Using intelligent 3D printing technology for processing, it has the characteristics of fast production speed and high precision. Metal-bonded flat diamond grinding wheel is widely used in the high-efficiency grinding of high-performance hard and brittle materials because of its strong abrasive grain holding force, high bonding strength, good wear resistance, long life, and ability to withstand large grinding pressure. . The grinding wheel will inevitably generate high temperature during grinding, and the grinding wheel manufactured by traditional technology is very easy to cause blockage of the working surface for this reason, which will lead to premature failure of the grinding wheel or thermal damage of grinding, whic...
