摘要:
A glass bottle is configured to improve the mechanics of liquid flow and prevent drip initiation. Additionally, the glass bottle eliminates dripping during pouring to enable drip free pouring. The dripping is prevented over a full range of pouring angles, which vary depending on the amount of liquid held in the glass bottle. A method of making the glass bottle and a method of enabling drip free pouring using the glass bottle are also disclosed.
摘要:
The invention relates to a method for grinding, polishing etc. curved surfaces of non-metallic solids, in particular glass bodies using a tool adapted at least in part to the surface to be machined and which moves relatively to the body to be machined while being compressed. This tool elastically follows the solid to be machined, and flowable grinding and/or polishing means are continuously supplied to the work space between tool and solid. The apparatus includes a rotating disk for seating and fastening the solid, elastically displacable, rigid tool presses at least against one part of the surface of the solid. Preferably it is the solid which is rotated while the tool is spatially fixed in elastically displaceable manner and is kept compressed in places against the solid.
摘要:
An object of the present invention is to provide a polishing method for producing, in a relatively short period of time, a tubular brittle material having an inner surface of high surface precision with a maximum roughness Rmax of 0.1 μm or smaller and a center line average roughness Ra of 0.01 μm or smaller, and to provide a tubular brittle material with high precision using said polishing method. The polishing method according to the invention is characterized by that the inner surface of the tubular material being pre-cut into a tubular shape using a honing machine is further polished with a sheet material having diamond abrasives attached thereon. Also claimed is a tubular brittle material obtained by said polishing method.
