Indicator heads designed or modified for use with machines specified by 2B119.a.
Technical Note:
Indicator heads are sometimes known as balancing instrumentation.
2. B. 120. Motion simulators or rate tables having all of the following characteristics:
a. Two axes or more;
b. Designed or modified to incorporate slip rings or integrated non‑contact devices capable of transferring electrical power, signal information, or both; and
2. B. 120. c. Having any of the following characteristics:
2. B. 120. c. 1. For any single axis having all of the following:
a. Capable of rates of 400 degrees/s or more, or 30 degrees/s or less; and
b. A rate resolution equal to or less than 6 degrees/s and an accuracy equal to or less than 0.6 degrees/s;
2. Having a worst‑case rate stability equal to or better (less) than plus or minus 0.05% averaged over 10 degrees or more; or
3. A positioning "accuracy" equal to or less (better) than 5 arc second.
Note 1: 2B120 does not apply to rotary tables designed or modified for machine tools or for medical equipment. For controls on machine tool rotary tables see 2B008.
Note 2: Motion simulators or rate tables specified by 2B120 remain controlled whether or not slip rings or integrated non‑contact devices are fitted at time of export.
2. B. 121. Positioning tables (equipment capable of precise rotary positioning in any axes), other than those specified by 2B120, having all the following characteristics:
a. Two axes or more; and
b. A positioning "accuracy" equal to or less (better) than 5 arc second.
Note: 2B121 does not apply to rotary tables designed or modified for machine tools or for medical equipment. For controls on machine tool rotary tables see 2B008.
2. B. 122. Centrifuges capable of imparting accelerations above 100 g and designed or modified to incorporate slip rings or integrated non‑contact devices capable of transferring electrical power, signal information, or both.
Note: Centrifuges specified by 2B122 remain controlled whether or not slip rings or integrated non‑contact devices are fitted at time of export.
2. B. 201. Machine tools and any combination thereof, other than those specified by 2B001, as follows, for removing or cutting metals, ceramics or "composites", which, according to the manufacturer's technical specification, can be equipped with electronic devices for simultaneous "contouring control" in two or more axes:
a. Machine tools for turning, that have positioning accuracies with all compensations available better (less) than 6 μm according to ISO 230/2:2014 along any linear axis (overall positioning) for machines capable of machining diameters greater than 35 mm;
Note: 2B201.a. does not apply to bar machines (Swissturn), limited to machining only bar feed thru, if maximum bar diameter is equal to or less than
