  ENVIRONMENTAL LITERACY Skip to main content ENVIRONMENTAL HAZARDS Environmental Health Hazards   Our planet needs us. If we take care of it, it will take care of us. What is an environmental hazard? An  environmental hazard  is a substance, state or event which has the potential to threaten the surrounding natural  environment  or adversely affect people's  health , including  pollution  and  natural disasters  such as storms and earthquakes . [1] [2]  It can include any single or combination of  toxic  chemical, biological, or physical agents in the environment, resulting from human activities or natural processes, that may impact the health of exposed subjects, including pollutants such as heavy metals, pesticides, biological contaminants, toxic waste, industrial and home chemicals . [3]  Our environment generally consists of physical, chemical and biological factors and our relationship with our environme...

  Skip to content CATEGORY: BORING MACHINES Home  »  Manufacturing Machines  » JIG BORING MACHINE: PARTS, WORKING, TYPES, OPERATIONS In this post, you’ll learn  what is Jig Boring Machine . With  Its Working Principle, Parts, Types, Operations, and Applications of jig Boring Machine . Jig Boring Machine The jig boring is the most accurate machine of all machine tools. This was first developed in the year 1910 in Switzerland and used as a locating machine.  Jig boring machine  is used for the production of  jigs, fixtures , tools, and other parts. That requires a high degree of accuracy. They are defined by terms of highest accuracy through rigidity, low thermal expansion, and precise means of measuring distance for locating and spacing holes. Jig Boring Machine The machining accuracy is high, within a range of 0.0025 mm. A jig boring machine looks like a  vertical milling machine . But so far its operation and accuracy are concerned that...
