Title:
歯科用ワークピースを製造するための装置
Document Type and Number:
Japanese Patent JP4690996
Kind Code:
B2
Abstract:
The invention relates to a device for the automated production of dental workpieces. A blank is inserted in a substantially slab-shaped support of the device, said support being dimensioned such that the blank does not extend beyond it in any direction. The blank is linked with corresponding inner walls of a recess provided in the support only on two opposite faces while a gap is left between the other inner walls of the recess and the corresponding faces of the blank. The inventive design allows to avoid tensions and microcracks of the blank material thereby caused. The gaps further make the blank directly accessible for a lateral working by the milling tool.
