  • Automated system for precision grinding of feedstock
    Patent number: 6852006
    Abstract: 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.

  • Centerless grinding machine control system
    Patent number: 5480342
    Abstract: A control system for controlling the position of a moveable regulating wheel in a centerless grinding machine, to provide a varying contour to the object being ground. The control system includes sensing means which measures the feed rate at which the object is being fed into the grinding machine. The rate at which the regulating wheel is moved is adjusted based on the feed rate of the object being ground, thus providing a high degree of control over the final shape of the ground object.
