Problems solved by technology

Therefore, there are cases where the object to be processed cannot be processed into a preset shape.
[0008] In addition, even if the holding member can be mounted at an appropriate position with respect to the workpiece, the position of the holding member relative to the workpiece may be shifted due to the environment or load acting during processing, transportation, and storage. Happening

Abstract

Provided are: a workpiece unit (10) that makes it possible to attach a holding member (1) to a workpiece body (1) at a suitable position and that minimizes displacement of the holding member (2) after attachment thereof; and a method for producing the workpiece unit (10). The workpiece unit (10) is provided with a workpiece body (1) and a holding member (2) arranged on at least a part of the outer circumference (1c) of the workpiece body (1). The workpiece body (1) comprises at least one first positioning section (1d) on a part thereof that faces the holding member (2). The holding member (2) comprises a second positioning section (2d) that engages with at least a part of the first positioning section (1d).

Description

[0001] The present invention is based on Japanese Patent Application No. 2015-056571 (filed on March 19, 2015), and the entire description of the application is incorporated herein by reference. technical field [0002] The present invention relates to a machined unit having a machined body for machining treatment and a manufacturing method thereof. Background technique [0003] When machining a workpiece such as ceramics or metal into a three-dimensional shape, the machining process is performed while holding the end of the workpiece. In addition, this to-be-processed object is also called a "blank". For example, in the dental industry, the outer edge region of disc (disk)-shaped zirconia as a workpiece is held by a processing device to cut out the prosthesis. [0004] Therefore, in the method of manufacturing a dental prosthesis described in Patent Document 1, the ring is attached to the outer edge of the blank with an adhesive, and the ring is fixed to the chuck of the p...
