Embodiment 1

[0011] Example 1: The specifications of grinding wheels used by a machinery factory in Shandong are 1-900*75*305-WA / F46L7V-40m / s and 1-750*75*305-PA / F60K7V-40m / s. According to this demand of the manufacturer, see figure 1 , Now make a grinding wheel with a diameter of 900mm, with a grinding zone 1 and a grinding zone 2, and the thickness is 75mm. The outer diameter of grinding zone 1 is 900mm, the inner diameter is 750mm, the abrasive is white corundum WA, the particle size is F46, and the hardness is L grade; the outer diameter of grinding zone 2 is 750mm, the inner diameter is 305mm, the abrasive is chrome corundum PA, the particle size is It is F60, and the hardness is K grade. In this way, two kinds of grinding wheels were originally required to be purchased, but now only one type can be purchased to meet the demand.

Embodiment 2

[0012] Example 2: A crankshaft factory in Zhejiang uses many grinding wheel specifications, respectively 1-1100*50*305-A / F46K7V-40m / s, 1-900*50*305-WA / F46L7V-40m / s, 1- 750*50*305-PA / F60M6V-40m / s, 1-600*50*305-SA / F80N6V-40m / s. According to this demand of the manufacturer, see figure 2 , Now make a grinding wheel with a diameter of 1100mm, which is provided with a grinding zone 3, a grinding zone 4, a grinding zone 5 and a grinding zone 6, and the thickness is 50mm. The outer diameter of grinding zone 3 is 1100mm, the inner diameter is 900mm, the abrasive is brown corundum A, the particle size is F46, and the hardness is K grade; the outer diameter of grinding zone 4 is 900mm, the inner diameter is 750mm, the abrasive is white corundum WA, the particle size is It is F46, the hardness is L grade; the outer diameter of grinding zone 5 is 750mm, the inner diameter is 600mm, the abrasive is chrome corundum PA, the particle size is F60, and the hardness is M grade; the outer diamet...

Abstract

The invention discloses a large ceramic straight-type grinding wheel for machining. The large ceramic straight-type grinding wheel comprises a central hole and a wheel body. The wheel body is provided with a plurality of grinding zones with different properties in the radial direction. The grinding zones are different in at least one of property indexes such as abrasives, granularity and hardness. The diameter of the large ceramic straight-type grinding wheel is 500-2000 mm, and the number of the grinding zones is two to four. No matter whether the grinding zones are identical in abrasive and granularity, the hardness of the grinding zones close to the central hole is higher than that of the adjacent grinding zones. The large ceramic straight-type wheel is novel and reasonable in structure design; due to the fact that the single grinding wheel is provided with the multiple grinding zones, the grinding wheel can adapt to various different grinding purposes, the effective using size of the grinding wheel is greatly increased, the resource utilization rate is increased, waste is reduced, and machining cost is reduced for factories adopting grinding wheels.

Description

technical field [0001] The invention relates to a consolidated grinding wheel for machining, in particular to a large ceramic flat grinding wheel suitable for various grinding purposes. Background technique [0002] With the development of the machining industry and the continuous improvement of the grinding process, the requirements for the grinding wheel are getting higher and higher, and the grinding division is getting finer and finer. As we all know, the flat grinding wheels produced by most manufacturers are integral, that is, the material, particle size, hardness and other properties of all parts of the same grinding wheel are the same. Although the manufacturing process of this grinding wheel is relatively simple, its suitable grinding objects are single. Therefore, manufacturers using grinding wheels need to purchase grinding wheels of various specifications and performances for different machine tools, different grinding workpieces, different grinding processes, a...
