175 years JBO:
“A success story with precision and threads“
1849 |
Johannes Boss founded a precision engineering workshop for the construction of precision scales. In the following decades, pill machines and other precision instruments for pharmacists were added. The company grew, built another factory in Onstmettingen and towards the end of the century transformed from a craft business to an industrially managed company. |
1914 |
The outbreak of World War I led to drastic changes. Precision scales were mainly made of brass. This material was unexpectedly needed for the production of ammunition. At the same time, there was a great need for tools - the entire production had to be changed. The decision was made in favour of thread cutting. Since then, “threading” has been the company’s central area of expertise. |
1949 |
Richard Boss has built up a close knit network of representatives across all four occupation zones. The company employs 55 people again. The 100th anniversary could be celebrated. |
1958 |
Rationalisation was in demand. A separate automation department was set up. In 1962, Mr. Heinz Boss joined the company. |
1985 |
A comprehensive range of thread gauges was added to the production and sales programme. Linear and rotary units, which had been produced in the automation department since the 1960s for the company’s own rationalisation, became an integral part of the sales programme. |
1997 |
Resumption of the production of thread milling cutters for distribution. 1999 Mrs. Melanie Boss joined the company as the 6th generation. In 2000, thread milling cutters and combination tools were added to the production programme. This was followed by a successive expansion of the production capacity, the construction of additional production halls at the site (2002 and 2008), as well as the substantial enlargement of the warehouse/dispatch department and the office space into an “open-space office” in 2010. |
2013 |
Production of PCD, CVD-D and PcBN tools. Internationalisation was driven forward. Today, JBO is represented in more than 60 markets worldwide. |
2019 |
The 3rd production and technical hall with air conditioning opens up new possibilities for the expansion of JBO beyond the current number of 160 employees. |
