What is Thru-Feed Grinding?

Thru-Feed Grinding is a production flat machining process that does almost everything a conventional double disc or vertical spindle grinder can do. Thru-feed grinding is the most efficient method known for high production surface grinding of small to mid size parts because it practically eliminates non-productive time. With the Thru-Feed Grinder, all machine time is grinding time, little is lost on fix-turing and preparation such as set-up, and loading and unloading of parts. Parts of almost any material and shape are fed into the Thru-Feed Grinder via a conveyor belt passing beneath a grinding wheel and finished parts are discharged continuously. It’s truly a high production grinding system.

Is Thru-Feed Griding right for your part? 

Process Qualifiers

  • The key qualifiers that gives the TFG machine a comprehensive edge
  • Medium to high part volume
  • High stock removal
  • Part handling capability
  • Parts produced in "dedicated" machining operations where one part is processed on one machine
  • Parts with high stock removal & lower tolerance ranges
  • Parts with light stock removal & tighter tolerance ranges
  • Parts requiring high stock removal for rough finishing operations
  • Parts produced in medium to high volume
  • Parts that can be "continuously" processed
  • Parts that have long, flat surfaces
  • Parts that only require 1-side grinding (also 2 sides can be accommodated
  • Parts that currently use fixturing for 1-sided grinding, but that have a flat backside reference face
