JPH0642059U - Surface plate for attaching polishing cloth of polishing machine - Google Patents

Abstract

(57) [Summary] [Purpose] The objective is to improve the surface plate of single-sided and double-sided polishing machines used for precision surface polishing. [Structure] A surface plate formed of a continuous porous structure and a surface plate formed of a two-layer structure in which the surface to be adhered to the polishing cloth is a continuous porous structure and the other layer is a non-porous structure. [Effect] In the work of sticking the polishing cloth to the surface plate, air did not remain at the bonding interface, and the polishing cloth sticking process could be performed easily and quickly.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a single-sided polishing machine and a double-sided polishing machine used for surface precision polishing.

[0002]

[Prior art]

 Along with the increase in the size of the polishing machine, the polishing cloth also becomes a large plate, and it takes considerable skill to attach the large-sized polishing cloth to the surface plate of the polishing machine. In addition, even a skilled person could not completely and evenly adhere to the surface plate without leaving air between the surface plate and the polishing cloth during this application work. Various methods are used to bleed air, such as poking a polishing cloth to bleed air from the needle hole.

[0003]

[Problems to be solved by the device]

 As described above, it is very troublesome to remove the air and the air that enters during the work of attaching the polishing cloth and the surface plate. The present invention solves such a problem and provides a surface plate in which no air remains at all by sticking a surface plate and a polishing cloth.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the surface of the plate having a continuous porous structure and the surface of the polishing cloth to be attached have a layer having a continuous porous structure and a two-layer structure formed of a non-continuous non-porous structure supporting the layer To provide the surface plate of.

[0005]

[Action]

 As described above, since the surface plate has a continuous porous structure, when adhering the polishing cloth and the surface plate, the air mixed in at the bonding interface permeates the surface plate and flows out. Therefore, since air does not remain at the bonding interface between the polishing cloth and the surface plate as in the past, there is no need for skilled bonding techniques, nor for the conventional problem of removing air such as needles after bonding. It solves the problems that were being addressed. Further, in order to improve the mechanical strength of the continuous porous structure, a non-continuous porous structure and a two-layer structure can be provided to provide a compact, lightweight surface plate without impairing the effects of the present invention. .

【Example】

 The result of making a cast iron polishing machine surface plate with a diameter of 1250 mm, a thickness of 150 mm, and a pore size of 10 to 30 microns, and having a continuous porous structure, and pasting a suede-like polishing cloth to which double-sided adhesive tape was pressed in advance. However, there was no air remaining on the adhesive surface and it could be easily applied.

A polishing machine surface plate was prepared by joining a stainless steel plate having a continuous porous structure with a diameter of 1500 mm, a thickness of 10 mm and a hole diameter of 20 to 60 microns to one surface of an iron plate having a diameter of 1500 mm and a thickness of 150 mm with an adhesive. As a result of applying a suede-like polishing cloth with double-sided pressure-sensitive adhesive tape pre-pressed, no air remained on the adhesive surface and a good polishing effect was obtained.

[0008]

[Effect of device]

 In the surface plate according to the present invention, the air remaining at the bonding interface of the surface of the polishing cloth permeates the surface plate and flows out when the surface is attached to the polishing cloth. It is possible to perform the polishing cloth sticking work very easily, quickly and surely without the need for skilled sticking techniques and the need for air bleeding work with a needle after sticking.
