Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a resin polisher for a stone polishing process capable of performing polishing without causing rattling or chattering.

[Conventional technology]

In a conventional rotary grindstone, a tip 12 is used in a polishing section as shown in FIG. The tip 12 is provided on one surface of the pedestal, and when the rotary grindstone rotates, the tip comes into contact with the work material to perform polishing.

[Problems to be solved by the device]

However, in the above-mentioned conventional chip attachment structure,
When polishing the small end surface of the work material, the abrasive layer has a small area of the abrasive layer because the chip is attached to the abrasive surface, which causes rattling and chattering, and tends to cause cracks and chips at the corners of the stone material.

Further, there is a drawback that the machining efficiency is lowered due to the influence of rattling and chattering, and a required finished surface cannot be obtained.

Further, in the grindstone production process, the conventional method is chip forming, and there is a drawback that the number of the chips is very large and the productivity is poor.

The present invention has been made to solve the above-mentioned drawbacks,
Even when polishing the small end surface of the work material, rattling and chattering are prevented to prevent cracks and chips at the corners of the work material, and improve the machining efficiency to obtain a good finished surface. Furthermore, it aims at improving the productivity of the grindstone itself.

[Means for Solving the Problems]

The present invention relates to a stone polisher resin polisher in which an abrasive layer is fixed to one side of a pedestal of a rotary grindstone with a rotary shaft attached to the central part and a hole for supplying a grinding fluid is provided for the hole in the pedestal central part. It is characterized in that an abrasive material layer having radially provided grinding fluid supply grooves is formed on the entire surface of the pedestal except for the hole at the center of the pedestal.

[Action]

According to the stone polishing resin polisher of the present invention,
The whole surface except the groove and the center hole is fixed to the pedestal with an abrasive layer, and the abrasive surface of this wide-surface abrasive layer shape touches the small end surface of the work material to polish it. Polishing proceeds smoothly without chattering.

〔Example〕

Hereinafter, the features of the present invention will be specifically described based on embodiments with reference to the drawings.

FIG. 1 is a plan view of a rotary grindstone showing an embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II, and FIG. 3 is an enlarged view taken along the line III-III in FIG. .

In the figure, a rotary grindstone 1 is formed by adhering an abrasive layer 3 to a pedestal 2. The abrasive material layer 3 has a disk shape having a central hole, and the entire surface except the groove and the central hole is formed as an abrasive material layer surface.
A hole 4 for mounting the rotary shaft is opened in the central portion, and a fixing screw 5 is provided. The rotary grindstone 1 is one in which the grinding surface 6 contacts the work material while polishing while rotating about the rotation axis. Since the grinding surface 6 polishes the work material, when polishing a small end surface. Polishing proceeds smoothly without rattling or chattering.

Further, the groove 7 is necessary for the grinding liquid supplied from the center hole to be well supplied to the connecting surface portion between the abrasive layer and the material to be polished.

The width B of the groove 7 is 20 mm or less and the depth H is for the purpose of the present invention.
May reach the pedestal with an abrasive layer thickness h or more. Here, the abrasive material layer thickness h is preferably 30 mm or less from the viewpoint of stability. Further, the outer diameter d is generally from a small diameter of 4 inches to a large diameter of 12 inches, and there is no particular limitation in terms of manufacturing and the effect of the invention.

A polishing test was conducted under the following conditions.

Polishing machine: Manual polishing machine, Work piece: Aoki granite, Dimensions: 6
00 x 70 x 90 (mm), Polished surface: 600 x 70 (mm), Grindstone size: 5
Inch, Spindle speed: 400 rpm, Processing field: Small end surface processing, Grinding fluid: Water.

FIG. 4 shows a schematic view of the polishing test situation.

As a result of performing the test under the above conditions, rattling and chattering did not occur during the machining of the small end surface, the machining was performed efficiently, and a good machined surface was obtained. In addition, the life of the grindstone is 30 days compared to the conventional 30 days.
It was extended to 60 days.

[Effect of device]

As described above, the present invention has the following effects.

(1) When polishing the small end surface of the work material, the area of the abrasive layer was increased, so rattling and chattering were eliminated, and cracks and chips at the corners of the work material were eliminated.

(2) The rattling and chattering during the processing of the small end face are eliminated, the processing efficiency is improved, and a good finished surface can be obtained.

(3) The area of the abrasive layer was increased, but the grooves were formed, so
It has become possible to extend the life of the grindstone without reducing the sharpness.
