\x051.Were there no friction,transmission of motion would be impossible.
\x052.An important function of a riser is to act as a reservoir of liquid metal to feed solidification within the mould.
\x053.Alloying is an important method of obtaining whatever special properties are required:strength,toughness,resistance to wear,magnetic properties,high electrical resistance or corrosion-resistance.
\x054.The common metallic materials are such metals as iron,copper,aluminum,magnesium,nickel,titanium,lead,tin,and zinc and the alloys of these metals,such as steel brass,and bronze.
\x055.One material can often be distinguished from another by means of physical properties,such as color,density,specific heat,coefficient of thermal expansion,thermal and electrical conductivity,magnetic properties,and melting point.
\x056.Plastics have specific properties,which may make them preferable to traditional materials for certain uses.In comparison with metals,for example,plastics have both advantages and disadvantages.
\x057.Organic materials will usually dissolve in organic liquids such as alcohol or carbon tetrachloride,but they will not dissolve in water.
\x05 8.The nonferrous metals are generally inferior in strength but superior in corrosion resistance as compared to ferrous materials,and most are more expensive.
\x05 9.The lathe bed is usually made of gray or nodular cast iron to damp vibrations and is made by casting.
\x0510.Many products,such as those made from colored plastic or other special materials,are more saleable because of appearance.
三、Translation(20 points)
\x05A lathe is a machine tool used primarily for producing surfaces of revolution and flat edges.Based on their purpose,construction,number of tools that can simultaneously be mounted,and degree of automation,lathes or,more accurately,lathe-type machine tools can be classified as follows:
(1)Engine lathes.
\x05(2)Tool room lathes.
\x05(3)Turret lathes.
\x05(4)Vertical turning and boring mills.
\x05(5)Automatic lathes.
\x05(6)Special-purpose lathes.
