Pull out protection system with special drive keys
- Published: March 20, 2018
The Safe-Lock pull out protection system from HAIMER ensures safe cutting tool clamping.
Special drive keys in the tool holder perfectly match the spiral shaped grooves on the cutting tool shank, thus creating frictional clamping forces and a positive locking form-fit. This effectively prevents the cutting tool from pulling out of the tool holder. Furthermore, it increases the productivity through faster permissible speeds and increased tool life.
Within the last ten years it has been confirmed over and over that this method of clamping the tool is often clearly superior to conventional milling chucks and Weldon shanked tool holders. This is proven by a large number of license partners, some of which rank amongst the world’s leading cutting tool and tool holder manufactures – for example Walter, Widia, Sandvik Coromant, Seco Tools, Sumitomo, Kennametal, Helical, Emuge Franken, Data Flute, Niagara, OSG and Mapal. In 2017, Iscar and Ingersoll also decided to offer tools with the Safe-Lock shank. Furthermore, the shrink, collet and hydraulic chuck Safe-Lock tool holder portfolio has become much larger within the last few years. In addition to the Safe-Lock hydraulic chucks from Kennametal, Mapal is already working to introduce its hydraulic chuck offering with Safe-Lock to the market.
Andreas Haimer, Managing Director of HAIMER GmbH, explains: “We are proud that our Safe-Lock pull out protection system has established itself as the new standard in the heavy duty and rough milling industry and is also becoming more and more important in other areas such as trochoidal milling. We are also very happy about our new license partners, who help expand the Safe-Lock portfolio and also make it available for more end-users.”
