Abstract

PURPOSE:To enable a grain layer to be rapidly securely exchanged with a new one when it is too worn to be used, by disposing a member formed with the grain layer removably in a body. CONSTITUTION:When a grain layer 3 formed on a sheet (polishing member) 2 is disabled by wear after a long use, a ring 4 is released from the fastening by screws 5 to be removed from a body 1. Next, each sheet 2 is slided in the centrifugal direction in a T-groove 7 of a body 1 to be removed from the body 1. Next, after another sheet 2 having unworn grain layer 3 is fitted in the T- groove 7, the ring 4 is again fastened to the disk portion 6 of body 1 by screws 5 to complete the exchange of sheet 2.

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a grindstone suitable for grinding hard and brittle members such as ceramics.

(Prior Art) Generally, when performing surface grinding of hard and brittle members such as ceramics, a grindstone is used which has a disk-shaped body with a diamond abrasive layer fixed to the entire main surface of one side by electrodeposition. However, electrodepositing a diamond abrasive grain layer over the entire main surface of the main body not only causes high costs, but also makes it difficult to completely remove the remaining abrasive grains after use when regenerating a depleted abrasive grain layer. After removal, it must be electrodeposited anew on the main body, which takes a lot of time, which is extremely uneconomical.

Therefore, as shown in Figures 3 and 4, a disc-shaped main body (
A grindstone (D) is used in which a closed thin plate (C) having a diamond abrasive layer (B) fixed on one side is adhered to A) in a radially and evenly spaced manner. However, this grindstone uses adhesive to fix the thin plate (e), so it takes time for the adhesive to harden, and the thin plate (C) does not peel off during processing. As the bonding work must be done carefully, it requires skill and a considerable amount of labor, and has the drawback of low work efficiency.

(Problems to be Solved by the Invention) The present invention has been made in consideration of the drawbacks of the two conventional types of grindstones mentioned above, and even if the abrasive grain layer is depleted, it can be quickly and reliably processed without requiring any skill. The purpose is to provide a grindstone that can be recycled.
