Wheel must be used with safety guards. The actual rotational axis of the wheel and its axis of rotation through the center of mass deviation from parallel state called static unbalance wheel. This is usually due wheel uneven density, both ends of the hole and the surface is not parallel or coaxial cylindrical deviation has caused.

Outline the overall structure of the system design
With precision diffraction grating and the differential inductor as a displacement sensor measuring instruments, designed a large range, high-precision contour cantilevered
cubic boron nitride system, discusses the outline of the overall structure of the system design, and describes the measurement principle. Secondly, the completion of the grating
synthetic diamond system design, describes the precise measurement principle of diffraction grating and access raster moire signals. Using resistance chain subdivision and subdivision combined hardware four ways to handle raster moire signals. Segmentation of the resistor chain, zero-crossing comparator transistor using direct conduction mode, simplifying the circuit structure.
