Efficient Production in Large Quantities

For thru-feed grinding, one or both wheels of the centerless grinding machine are canted out of the horizontal plane. The grinding wheel is titled to the other two axes a part of its surface pushes the part forward. This type of feeding is useful for quickly fabricating many parts in a rapid sequence for mass production capabilities. Thru-feed parts can only have right circular cylindrical ground surfaces. The wheel cannot be dressed to grind more complex shapes (for complex shapes see in-feed grinding).
