Grinding Process - MTI Instruments

A cylindrical grinding process finishes most wheel spindle surfaces. It is essential that this grinding process leave a surface finish that is smooth and free of defects with minimal runout. No grinder produces a perfect surface. Grinder wheel runout, improperly dressed wheels and fixture vibrations can cause chatter on the spindle surface finish. Chatter is a series of microscopic, repetitive ...

Because single-ended configurations use only one input, they can take twice the number of measurements compared to a differential configuration system with the same number of physical channels. On the other hand, this leaves single-ended ...

Understanding Errors In Hand-Held Measuring

15/03/2003  Measurement variation is present every time a part is measured. In some cases, when using a caliper or a 0.001-inch dial indicator, the step of the gage increment is large enough to hide most of the variation. In other situations, the 10:1 rule will require that an instrument of 0.0001- or 0.00005-inch resolution be used to inspect the part feature. When anything is measured to this level of discrimination, the measurement
