These indexers provide highly accurate motion, with the added capability to move medium to heavy loads. Our preloaded cam & turret mechanism provides a zero-backlash solution for all your automation needs. The servo drive makes it freely-programmable. The indexing unit rotates items to a specific position, either fixed or variable. These indexers are often used to place objects at exact points around a workspace so that they can be worked on, like a circular assembly line.
Indexing is an operation of dividing a periphery of a cylindrical workpiece into equal number of divisions by the help of index crank and index plate. A manual indexing head includes a hand crank. Rotating the hand crank in turn rotates the spindle and therefore the workpiece. Indexing is used to optimize the performance of a database by minimizing the number of disk accesses required when a query is processed. The index is a type of data structure. It is used to locate and access the data in a database table quickly.
There are four types of indexing in DBMS which are ordered indices, primary index, clustered index, and secondary index. The primary index is further divided into two types again which are dense index and sparse index. To index numerical data, values must be adjusted so they are equal to each other in a given starting time period. By convention, this value is usually 100. From there on, every value is normalized to the start value, maintaining the same percentage changes as in the nonindexed series.
