Seco expands EPB 5600 Shrinkfit range with highly secure Safe-Lock system
10/8/2013 11:00:00 AM

Fagersta, October 2013 – Seco has expanded its range of EPB 5600 Shrinkfit holders to allow them to be ordered with the Safe-Lock system, which achieves advanced pullout protection for round shanked cutting tools. This brings increased reliability, tool life and productivity to high-speed rough milling applications that involve workpieces machined from hard materials, such as titanium and special alloys.

The EPB 5600, when compared with a DIN-type Shrinkfit holder, achieves higher clamping forces, increased rigidity and the same 3 μm runout at 3xD. In fact, the EPB 5600’s clamping force, on average, is 33 percent stronger than an equivalent DIN holder. Combining this clamping force with the Safe-Lock system enables the EPB 5600 to eliminate tool ejection and achieve high material removal rates through increased depths of cut and higher table feeds.

The Safe-Lock system features drive pins in the Shrinkfit tool holder bores. The 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.

To achieve the best possible performance in the machining of titanium alloys, Seco 
recommends pairing the EPB 5600 with its Jabro® HPM JHP770 solid carbide end mill with optimised edge protection. All standard Jabro products are now available on demand with the Safe-Lock shank option.
