Abstract:
An automated apparatus for testing at least one sample wheel, comprising:a grindstone drive shaft that rotatably holds a grindstone;a first programmable servo motor coupled to the grindstone drive shaft and responsive to a first control signal, that drives the grindstone at a plurality of angular velocities as determined by the control signal;at least one sample wheel drive shaft disposed about a circumference of the grindstone, each sample wheel drive shaft of the at least one sample wheel drive shaft rotatably holding a corresponding sample wheel and movably engaging and disengaging the corresponding sample wheel with the grindstone; anda second programmable servo motor coupled to each sample wheel drive shaft and responsive to a second control signal, that drives each sample wheel drive shaft at a plurality of angular velocities as determined by the control signal so as to provide a variable slip ratio between each corresponding sample wheel and the grindstone.
