example 1

[0036]For ordinary flat grinding wheels, ProE software is used for physical construction, and the abrasive grains are arranged in concentric circles. Through layering, the mutual information of the binder and abrasive grains of each layer is obtained; using nickel-based alloy powder, the powder is prepared according to the The design is placed in a ring shape, the thickness of the alloy powder layer is 1mm, and 40 / 50 mesh diamond abrasive grains are placed above it, and the sintering of the bonding agent is completed by laser, so that the bonding agent is solidified point by point, and the abrasive particles are held; On top of it, alloy powder layer and abrasive grain layer are placed sequentially according to the entity structure information, and solidified again until the whole grinding wheel is completed.

example 2

[0038] This example is similar to Example 1, but the designed powder layer is two different alloy powders, wherein the thickness of the nickel-based alloy powder layer is 0.6mm, and a 40 / 50 mesh diamond abrasive grain is placed above it, and the laser is used to complete the alignment. The sintering of the bonding agent solidifies the bonding agent point by point and holds the abrasive grains; a copper-based alloy powder layer with a thickness of 0.5mm is placed above the bonding layer, and laser sintering is used to complete the curing of the copper-based alloy layer, thereby obtaining a composite Sintered layer: on the composite sintered layer, rotate the nickel-based alloy powder layer and the diamond abrasive grain layer, repeat the above steps until the whole grinding wheel is completed, and obtain a grinding wheel with a layered structure in the axial direction.

example 3

[0040] For ordinary butterfly grinding wheels, use AutoCAD software for three-dimensional structure, and set the abrasive grains to be evenly spaced, and obtain the information of the binder and abrasive grains through layered processing; The resin of mm is coated on the substrate according to the pre-designed shape, and 70 / 80 mesh CBN abrasive grains are placed on it; the resin is cured by ultraviolet rays to obtain a cured layer; on the cured layer, light curing is placed again according to the entity structure information The resin, as well as the grit layer, are cured again until the complete wheel is complete.

Abstract

A manufacturing method for an abrasive grain tool comprises the following steps: 1 building a three-dimensional solid model of a required abrasive grain tool; 2 cutting the three-dimensional solid model into layered slices and obtaining bonding agent information and abrasive grain information of each layer of slice; 3 distributing a first layer of bonding agent, accumulating a layer of abrasive grains on the first layer of bonding agent, and curing the first layer of bonding agent; 4 accumulating a second layer of bonding agent and abrasive grains on the cured first layer of slice, and curing; and 5 repeating the steps till the abrasive grain tool is finished. Due to the fact that the bonding agent and the abrasive grains are accumulated layer by layer, each layer is cured, and abrasive grain distribution and orientation in each layer can be effectively controlled, so that the abrasive grains can be set into a specific pattern meeting requirements of a specific tool abrasive mode including even abrasion. The result is that by reducing the required abrasive grain total quantity, the manufacturing cost of the abrasive grain tool is reduced.

Description

technical field [0001] The invention relates to the field of abrasive tools, in particular to a preparation method of abrasive tools. Background technique [0002] Abrasive tools have long been used in a variety of applications, including cutting, drilling, sawing, grinding, polishing, and more of material. For abrasive grain tools, according to the state of abrasive grains, it can be divided into two categories: consolidated abrasive grain tools and free abrasive grain tools. It is a tool to bond it into a consolidated state for cutting the workpiece. The role of the binder is to stick the abrasive grains together so that it has a certain shape and necessary strength. Commonly used binders are: ceramics, resins, rubber, metals and composite binders. The preparation process of a typical bonded abrasive tool is to mix and stir the abrasive grains and the binder, and then obtain the required tool shape by pressing and sintering or curing, and ensure the holding of the abras...
