Tapping is performed on blanks of nuts and other parts with threaded holes.

 

The German company Streicher is acknowledged to be one of the world leaders in the area of development, design and manufaturing of tapping machines for fasteners industry.

 

Streicher tapping machines have been working successfully in more than 70 countries worldwide, from Europe and Amerika to Australia. Although that machines have ranked for years among the top leading products on the international market, Streicher is continually improving their design and construction with the cooperation of renowned users. The advanced features found in every Streicher machine are the results of many years of experience, and the company will continue to offer modern technically and economically efficient solutions while meeting the highest standards.

 

Features of all Streicher machines:

- excellent and unsurpassed thread quality and the T.I.R. are achieved by the respective concept which is applied and the advanced design of all machines;
- easy handling and a quick tooling change;
- depending on the geometry of the parts to be machined, either mechanically operated feed units or electromagnetic vibration conveyor feed units are used;
-  in the event of faults occurring, a shutting flap prevents machined parts from accessing the part discharge conveyor belt;
-  the strong coolant current lubricates the thread tap very effectively and thus ensures a high cutting speed and a maximum tool life;
- the chips that are generated are discharged in an almost dry condition from the machine by means of a magnetic roller or a conveyor;
- the design and construction of all machines corresponds to the latest state of the art technology, and meets the requirements of the latest E.E.C. electrical and mechanical safety regulations for the prevention of accidents (CE requirements);
- mechanical and electrical safety devices ensure ideal protection for the operator and the machine;
- excellent layout and minimum space requirements thanks to a well defined, compact machine concept;
- attractive machine design with an illuminated workspace.

 

The top priority of Streicher is to provide an optimum level of advice and consultation for the customers as well as a fast solution for their problems. From a wide range of machines, it is possible to select a suitable machine for any tapping problem.
