Grinding is a term used in modern manufacturing practices to describe machining with high-speed abrasive wheels, pads, and belts. Grinding wheels come in a wide variety of shapes, sizes, and types of abrasives. In recent decades, grinding has been evolved both for producing very high quality parts and for fast economic production.
Although this guide concentrates on local exhaust ventilation (LEV), it is important to remember that the control or lack of general ventilation, including general supply and exhaust ventilation, can affect the performance of the LEV. For instance, a draught from an open door may challenge a welding hood
Two General Safety Rule for CNC Machines − Never operate a CNC machine without proper training or consulting the specific operator's manual for that particular machine and control type. − Never attempt to program a CNC machine without proper training or consulting the specific programmer's manual for that particular machine and control type.
