The HSK system was invented in Germany in the 1990's and is now very commonly found in European machine tools and spindles. HSK stands for "Hohl Shaft Kegel" - "Hollow Shank Taper", and as the name implies this type of interface has a cavity running through it. Unlike classical 'pull-stud' designs (CAT, BT, SK etc), HSK uses an internal drawbar mechanism which results in clamping force increasing with rotational speed. Additionally, the form features dual contact; on an axial face and the cone (1:10), which puts HSK in the upper echelons of tool holder performance.
The HSK-A form is probably the most common in the HSK family, and features drive slots which serve both to increase torque capability and provide rotational indexing (unequal slots). External features provide an interface for automatic tool change grippers and carousels. There is a bore milled directly into the side of the interface for RFID chip placement, and a threaded internal passage for coolant-through operation.
The ISO 3937 standard interface face/shell mill adapter utilizes a cylindrical boss, screw, and drive slots to mount shank-less milling tools.
The beginning of what has become Rego-Fix was Fritz Weber founding "Fritz Weber Feinmechanik und Werkzeugbau" in Reigoldswil, Switzerland in 1950. His first serially manufactured product was a broomholder; a humble origin that has shaped the company's history for many years. By 1955 the company employed 15 people and began to venture into toolmaking, and by 1970 also had become a successful brand in cheese cutting, as well as yoghurt and gas bottling machines. In 1972 Rego-Fix invented the ER machine collet system, the innovation which would make the company world-renown. Interestingly, the mechanism for the ER collet system had been used in broom handles from the beginning, but the application to machine tools was much more important. Tool holding technology was continuously developed by the company since that moment, and has produced an additional revolutionary system, PowRgrip. Today Rego-Fix is recognized at the top level of premium brands in the machining industry.
