Automated system for precision grinding of feedstock
View Patent ↗A grinding system for grinding feedstock includes a transport apparatus, a grinding apparatus, and a controller. The transport apparatus continuously transports feedstock of an arbitrarily long length at a desired feed rate, and the grinding apparatus grinds the feedstock transported by the transport apparatus. The controller controls a grinding position of the grinding apparatus and a longitudinal position of the feedstock during grinding to be coordinated with each other.
1. A centerless grinding apparatus comprising:
a work wheel for grinding feedstock;
a bottom support unit for providing bottom support to the feedstock during grinding;
a back support unit for providing back support to the feedstock during grinding; and
a controller for controlling a lateral position of the work wheel relative to the back support unit,
wherein the back support unit and the bottom support unit interact to support the feedstock during grinding,
wherein the bottom support unit is laterally movable relative to the back support unit,
wherein the bottom support unit is physically linked to the work wheel and moves laterally with the work wheel, and
wherein a separation distance between the work wheel and the back support unit is varied during grinding such that the feedstock is ground to a diameter that varies along its length.
2. A grinding apparatus according to claim 1 , wherein the bottom support unit and the back support unit are formed with a plurality of projections that intermesh.
