To study the prevalence of occupational injuries in the welders and lathe machine operators and their hazard perception. Hazard perception and occupational injuries in the welders and lathe machine operators of Rawalpindi and Islamabad. A case study of airbearing machining confirms the statement that a good result of the micromachining does not depend on machine performance alone, but also on the technology applied. One of these parts, an aerostatic bearing component has been succesfully machined on the Super-Mikroturn CNC. This first generation of machines was followed by the advanced computer numerically controlled types for machining of complex precision workpieces. Hembrug has originally developed the conventional Mikroturn ultra precision facing lathes, for diamond turning of computer memory discs. This concept is to be explained with some major advantages of hydrostatics compared with aerostatics at universal micromachining applications. The Hembrug ultra precision lathes have been exclusively designed with hydrostatic principles for main spindle and guideways. Micromachining of precision elements requires an adequate machine concept to meet the high demand of surface finish, dimensional and shape accuracy. 2, Along Monongahela River, Homestead, Allegheny County, PAĪir Bearings Machined On Ultra Precision, Hydrostatic CNC- Lathe THE 78 1/2' X 100 LATHE BORES OUT CENTERS, OR TREPANNS, OF FORGING.

The machine and specific design elements of the setup will be shown. Building on the OptiCentric® and OptiSurf® measurement systems, Trioptics has developed their first lathe centering machines. Using a diamond turning process, all relevant errors of single mounted lenses can be corrected in one post- machining step. Instead, lathe centering can be used to machine the mount with respect to the optical axis. These accuracies are hard to meet with traditional assembly methods. The shift and tilt of individual lenses as well as the air gap between elements require accuracies in the single micron regime. High precision optics depend on precisely aligned lenses.
