A lathe can be used to create a smooth, flat, face very accurately perpendicular to the axis of a cylindrical part.  First, <a href="http://www.nmis.org/EducationTraining/machineshop/05/l_instchuck.mpg"><i>clamp the part securely in a lathe chuck (636kB)</a></i>. Then, install a facing tool.  Bring the tool approximately into position, but slightly off of the part.  Always <a href="http://www.nmis.org/EducationTraining/machineshop/05/l_handrotate.mpg"><i>turn the spindle by hand (248kB)</i></a>before turning it on.  This ensures that no parts interfere with the rotation of the spindle.  Move the tool outside the part and adjust the saddle to take the desired depth of cut.  Then, feed the tool across the face with the cross slide.  The following clip shows a roughing cut being made; about 50 thousandths are being removed in one pass. <a href=126,7562
