History edit
United States edit
The company was established in 1919 as Ex-Cell-O Tool and Manufacturing Co. by a group of tool and die makers, all of whom were former employees of Ford Motor Company. The site of the original shop was located in Highland Park, Michigan. This location is a few blocks from the world's first automobile assembly line, at the Highland Park Ford Plant.[1][2] Newton "Woody" Woodworth served as the first president and general manager.[1]
In its early years, around sixty percent of the company's business was manufacturing parts and fixtures for aircraft.[3] Due to its focus on the aviation industry, the company name was changed to Ex-Cell-O Aircraft and Tool Corporation in 1927. At this time, they also made grinding machines (including Carboloy-branded grinders that Carboloy, Inc. sold) and air-driven grinding spindles.[4]
In 1937, Woodworth left the company, which was then reorganized as Ex-Cell-O Corp. The more general name was chosen to reflect their increasingly diverse product lines, which included high-precision thread grinders, boring machines, facing machines, and lapping machines.[4]
Ex-Cell-O was part of the Arsenal of Democracy.[5] During World War II, they manufactured the following products for military use:
- Nozzle plates for rockets
- Aircraft engine parts
- Boring machines
- Thread grinding machines
- Center lapping machines
By the mid-1960s, the company was based in Troy, Michigan.[6]
In 1986, Ex-Cell-O was acquired by defense industry conglomerate Textron for $77.50 per share in cash, totaling about $1.1 billion (about $3.1 billion in 2023 dollars). Under the merger agreement, Ex-Cell-O became a wholly-owned subsidiary of Textron.[7]
Ex-Cell-O began laying off all employees on April 28, 2006.
Canada edit
Ex-Cell-O Corporation of Canada, Ltd. manufactured heavy machine tools such as ram-type milling machines. The business was located at 120 Weston Street in London, Ontario.[4]
India edit
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. In 1978, the company bought itself, becoming fully Indian-owned and independent from the American branch, changing its name to XLO India Limited.[8][10]
