Centerless grinding apparatus

Abstract

Some implementations of the described invention provide an improved centerless grinding apparatus in which grinding is efficiently operated by reducing the idle time of the grinding wheel. While the described apparatus can comprise any suitable feature, in some cases, it includes a first regulating wheel and a second regulating wheel are axially aligned side by side. In some cases, a first grinding area is provided between the first regulating wheel and a first blade. In some cases, a second grinding area is provided between the second regulating wheel and a second blade. Additionally, in some cases, a grinding wheel is mounted on a grinding wheel Z-slide to be moved reciprocatively between the first grinding area and the second grinding area. In this way, grinding is efficiently operated by reducing the idle time of the grinding wheel.

What is claimed is: 
     
         1 . A centerless grinding apparatus in which a grinding wheel grinds a work supported on a regulating wheel and a blade spaced apart from and facing to each other comprising:
 a regulating wheel having a first regulating wheel and a second regulating wheel which are axially aligned with respect to each other;   a first blade disposed spaced apart from and facing to said first regulating wheel to form a first grinding area therebetween;   a second blade disposed spaced apart from and facing to said second regulating wheel to form a second grinding area therebetween;   a grinding wheel mounted on a grinding wheel slide which moves forward and backward to make the grinding wheel face said first grinding area and said second grinding area reciprocatively;   wherein said grinding wheel performs oscillation grinding on a work supported on said first regulating wheel and said first blade when it is positioned in said first grinding area, and   wherein said grinding wheel performs oscillation grinding on a work supported on said second regulating wheel and said second blade when it is positioned in said second grinding area.   
     
     
         2 . A centerless grinding apparatus in which a grinding wheel grinds a work supported on a regulating wheel and a blade spaced apart from and facing to each other comprising:
 a regulating wheel having a first regulating wheel and a second regulating wheel which are axially aligned with respect to each other;   a first blade disposed spaced apart from and facing to said first regulating wheel to form a first grinding area therebetween;   a second blade disposed spaced apart from and facing to said second regulating wheel to form a second grinding area therebetween;   a grinding wheel mounted on a grinding wheel slide which moves forward and backward to make the grinding wheel face said first grinding area and said second grinding area reciprocatively;   wherein said grinding wheel performs oscillation grinding on a work supported on said first regulating wheel and said first blade when it is positioned in said first grinding area while a grinded work is carried out of said second grinding area and a new work is carried into said second grinding area, and   wherein said grinding wheel performs oscillation grinding on a work supported on said second regulating wheel and said second blade when it is positioned in said second grinding area while a grinded work is carried out of said first grinding area and a new work is carried into said first grinding area.   
     
     
         3 . The centerless grinding apparatus as set forth in  claim 1 ;
 further comprising a regulating wheel slide having said first regulating wheel and said second regulating wheel mounted thereon and moving in the axial direction of the regulating wheels.   
     
     
         4 . The centerless grinding apparatus as set forth in  claim 3 ;
 wherein said first regulating wheel and said second regulating wheel are integrally formed to constitute a wide width regulating wheel have a width which is twice or more of the width of said grinding wheel.   
     
     
         5 . The centerless grinding apparatus as set forth in  claim 4 ;
 wherein said grinding wheel moves among said first grinding are and said second grinding area to grind a work having a width corresponding to the width of said wide width regulating wheel which is disposed among said first grinding are and said second grinding area.   
     
     
         6 . The centerless grinding apparatus as set forth in  claim 2 ;
 further comprising the regulating wheel slide having said first regulating wheel and said second regulating wheel mounted thereon and moving in the axial direction of the regulating wheels.
