Thin resin wheel

Abstract

The invention discloses a thin resin wheel. The thin resin wheel is 105mm to 125mm in diameter and 0.8mm to 1.0mm in thickness. The components of the thin resin wheel comprise white corundum, monocrystalline corundum, phenolic resin powder, resorcin-formalin, light calcium carbonate powder and potassium fluoroaluminate powder, are simple and easy to allocate, have no special requirements for forming process and can be produced by conventional process. The thin resin wheel manufactured is narrow in cuts, long in cutting service life, quick to cut and low in generated cutting heat, so that cut section has no defects such as erosion, burrs and flanges.

Description

technical field [0001] The invention relates to an abrasive abrasive tool, in particular to a thin resin grinding wheel for cutting stainless steel plates. Background technique [0002] Thin slice resin grinding wheel is one of the preferred abrasive tools for stainless steel plate cutting. It is mainly matched with manual cutting equipment and has a wide range of application markets. The cutting of stainless steel plate by thin slice grinding wheel is essentially a grinding process. Grinding will inevitably generate cutting heat. Excessive cutting heat will not only burn the workpiece, but also cause damage to the grinding wheel. Therefore, reducing cutting heat is the key issue to improve cutting quality. Under the current technical conditions, in addition to the cutting process that can control the amount of cutting heat generated, the components and structure of the thin-section grinding wheel also have a great influence on the cutting heat. There are two main types of ...

AI Technical Summary

Problems solved by technology

However, the thin-section grinding wheel with low molding density has a loose structure and low strength, and the strength requirement can only be met by increasing the thickness of the grinding wheel

Excessive thickness of the thin slice grinding wheel will increase the cutting amount, waste steel, and it is difficult to achieve cutting accuracy

On the other hand, the thin-section grinding wheel with low molding density consumes a lot during cutting, the cutting ratio is small, and the service life is short. Frequent replacement of the thin-section grinding wheel during the cutting process will inevitably reduce labor efficiency.

On the contrary, the high-density thin-section grinding wheel has a compact structure and a large hardness value. Although the thin-section grinding wheel itself has less loss during cutting operations, the cutting efficiency is low, and the cutting heat generated is indeed high. There are ablation marks and burrs on the incision section of the workpiece. At the same time, it also causes the resin bond of the thin-section grinding wheel to be carbonized, which makes the thin-section grinding wheel prone to brittle crack damage
