Cutting Tool Materials: High Speed Steel (HSS) provides good wear resistance and costs less than cobalt or carbide end mills. HSS is used for general-purpose milling of both ferrous and nonferrous materials. Vanadium High Speed Steel (HSSE) is made of high speed steel, carbon, vanadium carbide and other alloys designed to increase abrasive wear resistance and toughness.
Feb 01, 2012· Upper bound solutions to a 4-High reversing aluminium cold-rolling sheet mill was obtained in this work using both analytical and graphical methods. The upper bound method was applied to the rolling of an Al 1200 sheet from 7mm to 0.6mm in six passes. It was observed that both methods were very effective in predicting upper bound load value with the graphical method giving a …

Nov 22, 2013· As the name suggests the 4 Hi mill employs 4 rolls, two these are the work rolls and the other two are the backup rolls. The rolls between which the cold rolling actually takes lace is called the work roll. The OD of the work rolls is between 208 to 225 mm or 145 to 155 mm, while the backup roll may be 575 to 610 mm.
Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in work roll diameter: Reduces overall separating force required for reductions
