Embodiment 1

[0041] Embodiment one: see attached figure 1 As shown, the method for preparing a superabrasive grinding wheel for processing heterogeneous metal components includes: mixing materials, loading molds, hot pressing, sintering and hardening, and then processing the hardened grinding wheel molded body to the shape and size required by the drawing, according to the super abrasive Hard grinding wheels are put into storage after passing the national standard inspection.

[0042] (1) Mixing: Weigh 20 parts of polyimide resin powder, 60 parts of copper powder, 5 parts of graphite powder and 15 parts of zinc oxide according to the weight ratio, pre-mix by hand, pass through a 60# sieve, and then put Mix mechanically in a ball mill. A drum made of ceramic material is selected, the ball-to-material ratio is 2:1, the rotating speed of the drum is 60 rpm, and the mixing time is set to 5 hours. After the mixing is completed, pass through the 200# sieve to obtain the binder; according to ...

Embodiment 2

[0045] Embodiment two: the technology of preparing emery wheel is identical with embodiment one, specifically:

[0046] (1) Mixing: Weigh according to the weight ratio: 30 parts of polyimide resin powder, 55 parts of copper powder, 5 parts of graphite powder, 10 parts of zinc oxide, pre-mixed by hand, passed through a 60# sieve, and then put into Mix mechanically in a ball mill. A drum made of ceramic material is selected, the ball-to-material ratio is 2:1, the rotating speed of the drum is 60 rpm, and the mixing time is set to 5 hours. After the mixing is completed, pass through a 200# sieve to obtain the binder; according to the density of the binder and the volume of the grinding wheel, mix 70 parts of the binder and 30 parts of diamond, mix 70 parts of the binder and 30 parts of cubic boron nitride (CBN) , cross 120# screen cloth respectively, obtain diamond forming material, CBN forming material; The surfaces of described diamond and CBN are nickel-plated;

[0047] (2) ...

Abstract

The invention discloses a super-abrasive grinding wheel used for machining a heterogeneous metal component. The super-abrasive grinding wheel is composed of a base body and a ring-shaped grinding layer, wherein along the axial direction of the base body, the ring-shaped grinding layer consist of a first ring-shaped grinding layer, a second ring-shaped grinding layer and graphite paper; the graphite paper is arranged between the first ring-shaped grinding layer and the second ring-shaped grinding layer; each of the first ring-shaped grinding layer and the second ring-shaped grinding layer is formed by combining an abrasive material with resin; the abrasive material contained in the first ring-shaped grinding layer is different from that contained in the second ring-shaped grinding layer. Compared with the conventional grinding wheel, the grinding wheel disclosed by the invention has the advantages that the production efficiency is improved, grinding wheel trimming time is prolonged, self-sharpening performance of the grinding wheel is improved, a workpiece burning phenomenon of the grinding wheel caused by blockage is eliminated, shape keeping ability of the grinding wheel is improved, and trimming times of the grinding wheel in a workpiece machining process is reduced; and moreover, component machining precision is ensured, and the shape of the grinding wheel can be adjusted according to the shape of a machined object, and therefore, the super-abrasive grinding wheel is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of superabrasive grinding wheels, in particular to a superabrasive grinding wheel used for processing heterogeneous metal components, which can simultaneously process welding bars containing two kinds of metals. Background technique [0002] Grinding wheel is the main tool for grinding, which is a porous object composed of abrasive and bonding agent. Resin grinding wheel is a grinding wheel whose binder is resin. It has the advantages of small grinding force, low grinding temperature, good self-sharpening, and high grinding efficiency. It is widely used in the grinding of hard and brittle materials such as cemented carbide, ceramics, and glass. Processing. With different abrasives, the characteristics of grinding wheels vary greatly, and often a kind of abrasive grinding wheel has a specific processing object. [0003] For example, in the traditional process, diamond grinding wheels are mainly used for processing ha...
