Seco Tools (UK) Ltd, Alcester
(www.secotools.com), has expanded its range of EPB 5600 Shrinkfit tool-holders to allow them to be supplied with the Safe-Lock system, which is designed to prevent round-shank tools from being ‘pulled out’ of chucks; this is a problem that manufacturers can experience when rough-milling difficult-to-machine materials.
The Safe-Loc system on Seco’s EPB 5600 Shrinkfit holders eliminates tool ejection and, as a consequence, delivers a more reliable machining process. Furthermore, the inherent security of the Safe-Lock system means that cutting data can be increased (depths of cut, speeds and feeds), helping to improve productivity; tool-life is also improved. Furthermore, the possibility of scrapped work-pieces caused by micro-creeping is avoided.
The Safe-Lock system features drive pins in the Shrinkfit tool-holder bores. These pins, when combined with spiral-shaped grooves in the cylindrical cutting tool shank, prevent the tool from being ‘pulled out’ from the chuck during extreme machining conditions.
