frictional force to pull the material into the roll gap frictional force at the start must be higher than the frictional force at the end high friction could damage the surface of the rolled product or cause sticking lubricant selection lowers and controls levels of friction
The reason it didnt work is because the least amount of friction would stop the sails As the motor turns the rubber band would stretch until it built up enough force to turn the sails When it had enough force built up the sails would suddenly break free and spin a little relieving all of the pressure in the belt
Overheating a tool causes small crack to form on the edge When a stress is applied as in a roughing cut the tool end may break off Give two reasons for center drilling a work piece in a lathe Limitations on the depth of cut for an end mill are the amount of material to be removed the power available and the rigidity of the tool

defects commonly occur due to impurities in the material scale rust or dirt Adequate surface preparation prior to the metal rolling operation can help avoid these Most serious internal defects are caused by improper material distribution in the final product Defects such as edge cracks center cracks and wavy edges
Feb 27 2015 Even if you can match the index of refraction for one part of a Pyrex stirring rod for example the match will not be perfect for other parts of the rod Thats why a ghostly image of the rod remains even with the best index matching The index of refraction of the oil and of the glass too is a function of temperature
Jan 05 2016 Mill HEAD LINERS Head liners are of the segmental type constructed of Manganese Steel Chrome molybdenum or NiHard and are designed to pass easily through the manhole opening or discharge opening in the case of rod mills For ball mill work ribs are cast with the feed head liners to deflect the ball mass and minimize wear on the headliner itself

Dec 26 2015 2 Add a piece of heavy channel as a base for the mill Make it extend around 23s of the height of the column to each side of the mills base Then add an two angle brackets from the top of the mill to the ends of that base to diagonally brace it Kind of like the X braces at the outboard end of the shafts on the horizontal mills
The piece is then rotated 90 and passed through the same hole In the case of wire the mill exerts stress not from just two directions but from six because of the shape of the grooves Annealing is required as above The rod is passed through the mill until it approaches the desired size
