Seco Takes Hole Making to Deeper Levels at IMTS with Steadyline Tooling

TROY, Mich., September 10, 2018 – Seco Tools brought new capabilities in long-reach turning and boring operations to light at IMTS 2018. The company presented several new additions to its well-known series of Steadyline turning/boring bars and their respective heads including 1.00" (25 mm) diameter Steadyline bars, GL25-turning heads, 4.00" (100 mm) diameter Steadyline bars and rough and fine boring heads. 

The new turning bars incorporate the industry’s most effective vibration dampening system to enable the easy turning and boring depths up to 10xD for both small and large size holes. For both turning and boring Steadyline operations, shops can quickly and effortlessly exchange tool heads by virtue of Seco’s special GL connection. The GL connection ensures a fast and firm mounting of the heads to the Steadyline bars with modularity and the capability of 180° head orientation. The GL connection also ensures a centering accuracy and repeatability of 5 microns.

The 1.00" (25 mm) diameter bars with GL25 workpiece side connection are for 6xD, 8xD and 10xD reaches and include carbide-reinforced bars for the deepest reaches along with Seco-Capto™, HSK-T/A and cylindrical shank machine side interfaces.

The GL25-turning heads encompass 16 turning heads including general turning, recessing and back boring heads with DN..11, CC..09, DC..07, DC..11, TC..11 and VB..11 inserts.

The larger size 4.00" (100 mm) diameter bars accommodate existing GL50 turning heads and include Jetstream® high-pressure coolant solutions through a BA-to-GL50 adapter. For rough and fine boring, heads with BA060 and BA080 machine side interfaces allow for boring diameters from 2.600" to 4.530" (66 mm to 115 mm).
