I have a main stage that must open another stage without losing focus of the first one. I know i can call mainWindow.requestFocus() after calling secondWindow.show() but i want to make it to work without the first window even losing focus.. I wanto to do this because the second stage is a notification window with StageStyle.TRANSPARENT, that stays always on top and closes itself after …

One of their experiments appeared to go wrong when the grinding wheel was fed slowly through the workpiece with a large depth of cut, but without any electrical current. To their surprise and astonishment, the wheel walked right through the workpiece as though it was a milling cutter—Creep-Feed Grinding (CFG) was born.

Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled material-removal process. The processes that have this common theme are collectively called subtractive manufacturing, in contrast to additive manufacturing, which uses controlled addition of material.Exactly what the "controlled" part of the definition implies can vary, but it ...

A similar approach was taken to calibrate the scale-up procedures from the single-stage batch grinding with balls to match the full-scale ball mill operation. The calibrated scale-up criteria were then applied to the single-stage Cylpebs grinding data. In the simulations, the charge was set at 23% volume as in the plant survey.

On a single-stage compressor, all cylinders will be the same size and have their own inlet valves. On the other hand, in two-stage compressors, there is only one inlet, and the second piston is shorter than the first, and the two are linked by a cooling tube, which brings the temperature of the air down before the second round of compression.

If Mohs hardness is less than 5, a hard metal bond grinding pads and the wear-resistant resin bond diamond pad is applied. If Mohs hardness is 5-7, use medium-base metal bond grinding pads and general-purpose metal bond grinding pads. If Mohs hardness is more than 7, use a flexible metal bond grinding pad and sharp resin bond polishing pad.
