Note the use of rolling cutter 
 First, the characteristics of rolling process 
 1, the carbide wheel long life; 
 2, the rolling high efficiency, high degree of finish; 
 3, can effectively improve the surface hardness of the workpiece. 
 Second, the amount of rolling 
 1, the rolling speed :60-250m / min (can increase) 
 2, feed rate: S = 0.1-0.2mm/rev (once completed) 
 3, the rolling amount of interference :0.4-0 .5 mm 
 4, the actual intake pressure :0.02-0 .04 mm 
 Third, pay attention 
 1, the wheel center and the center of the workpiece axis should be high; 
 2, the rolling surface and rolling surface of the workpiece shaft must be clean and free of grease; 
 3, rolling to a complete, repeatedly rolling will produce spots and peeling; 
 4, rolling a small plane and axial components should be 1 ° -1.5 ° in the Cross (two-axis cross); 
 5, lubrication rolling, the liquid (kerosene or oil is recommended) must be clean, rolling effect will be better.
