T/WLJC 59-2019 Quartz Chip with Reverse Edge Waveform Cylinder
T/WLJC 59-2019
Basic Information
Scope
Scope: This standard specifies the type and specifications, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of quartz crystal chip reverse-edge waveform cylinders. This standard applies to quartz crystal chip reverse-edge waveform cylinders. Main technical content: In the standard name, "quartz crystal chip" refers to a raw piece of piezoelectric quartz crystal. "Reverse-edge waveform cylinder" is a structural type of reverse-edge roller, with other types including "reverse-edge ball" and "reverse-edge straight cylinder". The standard provides the basic structural type of waveform cylinders, and the inner diameter and inner wall waveform R dimensions of 14 specifications in two commonly used series. The standard stipulates the basic technical requirements of reverse-edge waveform cylinders, including materials, dimensional tolerances, surface quality, and assembly interchangeability.
