Compumotor Division, North America: Home > Support > Applications > Flute Grinder
A low-cost machine for grinding the flutes in twist drills requires two axis of movement. One moves the drill forwards underneath the grinding wheel, the other rotates the drill to produce the helical flute. At the end of the cut, the rotary axes has to index the drill round by 180 degrees to be ready to grind the second flute. The linear speed of the workpiece does not exceed 0.5 inches/sec.
Motion Control Requirements:
This is a natural application for stepper motors, since the speeds are moderate and the solution must be minimum-cost. The grinding process requires that the two axes move at accurately related speeds, so the controller must be capable of performing linear interpolation. The small dynamic position error of the stepper system ensures that the two axes will track accurately at all speeds.
