Abstract

PURPOSE:To provide a grinding cloth which is durable against a use for a long time without the occurrence of choking by a method wherein polishing layers formed of resin containing grinding grains are applied and cured intermittently in a given thickness at intervals of a given distance on the surface of woven cloth. CONSTITUTION:Polishing layers 2 formed of resin containing grinding grains are applied and cured intermittently in a given thickness at intervals of a given distance on the surface of woven cloth 1. Thus, grinding chips are transferred in a recessed part, where the polishing layer 2 is not formed, for removal. This constitution reduces the occurrence of choking of the polishing layer 2, and causes a polishing cloth to be durable against a use for a long time.

The standard thickness of the polishing layer 2 is about 50 to 200 μm, and can be increased or decreased to a range of about 30 to 500 μm as necessary, and is changed as appropriate depending on the type of wood to be ground.

Generally, as shown in FIG. 3, in an embodiment where a circular abrasive layer is formed on a woven fabric, the spacing from one protrusion to the next is determined as a function of the thickness of the protrusion (abrasive layer). That is, the wider and taller the protrusion becomes, the more the distance between the next protrusion needs to be increased. Usually, when the convex surface is about 0.5 to 1 mm2, the interval between the convex parts is 5 to 10 mm, and the standard height is 0.3 mm in this case.

Note that in order to increase the fixing force of the abrasive grains in the polishing layer 2, it is recommended that a fiber substance be mixed into the resin in advance. As the fiber material, any high-strength, heat-resistant material such as graphite fiber or glass fiber can be used, but in particular metal fiber such as stainless steel or iron with a thickness of 10 to 50 mm can be used.
10 to 2 μm, length of about 200 to 1000 μm
