The Indian branch was founded on March 10th, 1958, [8] as Messrs. Amerind Engineering Company of Bombay, [9] later known as Ex-Cell-O India Ltd, with technical and equity support from the American branch. The company mainly manufactured propeller shafts, machine-tools, and steering gear assemblies at this time.
Sine bar set up with one end raised on a stack of gauge blocks Trigonometric triangle with sides. The opposite side is perpendicular relative to AC axis. A sine bar consists of a hardened, precision ground body with two precision ground cylinders fixed at the ends. The distance between the centers of the cylinders is precisely controlled, and ...
Surface plates are a common tool in the manufacturing industry and are often fitted with mounting points so that it can be an integrated structural element of a machine such as a coordinate-measuring machine, precision optical assembly, or other high precision scientific & industrial machine. Plates are typically square or rectangular, although ...

Sir Joseph Whitworth popularized the first practical method of making accurate flat surfaces during the 1830s, [2] using engineer's blue and scraping techniques on three trial surfaces, in what is known as Whitworth's three plates method. [3] By testing all three in pairs against each other, it is ensured that the surfaces become flat.
They are used as a reference for the calibration of measuring equipment used in machine shops, such as micrometers, sine bars, calipers, and dial indicators (when used in an inspection role). Gauge blocks are the main means of length standardization used by industry.
Marking out or layout means the process of transferring a design or pattern to a workpiece, as the first step in the manufacturing process. [1] It is performed in many industries or hobbies although in the repetition industries the machine's initial setup is designed to remove the need to mark out every individual piece.
