Centerless Grinding (Thru-Feed Grinding) ... Parts are ground by being fed in and out through the regulating and grinding wheel in a straight line to ensure maximum grinding efficiency and therefore minimum cost. Due to the low lead times of thru-feed grinding, we can often produce lead times of less than 24 hours. ...
Centerless grinding is an abrasive cutting process to remove material from a workpiece. Similar to centered grinding except without a spindle. This method is favored by high volume operations because parts can be quickly inserted and removed from the process.
Resin bonding enhances the efficiency of centerless grinding and produces a more resilient wheel. Like a grinding wheel, a regulating wheel is made of an abrasive material but usually is bonded with rubber or some other similar substance.
It can be more cost effective to hire a grinding company that has this system, to do the work. The impact then, of the centerless grinding process, has been to lower costs to a solid degree. It has also made industry more efficient because items can be mass produced with much more efficiency using this process.
Thrufeed grinding is widely regarded as one of the most efficient grinding processes as it minimizes downtime while still producing a quality finish.
