TaeguTec has now significantly expanded its WINIGROOVE miniature insert system beyond grooving applications to deliver a comprehensive solution for small-hole internal machining. The enhanced product line now encompasses internal turning, profiling and threading operations, addressing the growing demand for versatile tooling solutions in small parts machining.
The WINIGROOVE system utilises an innovative new insert geometry that is combined with an inclined clamping mechanism to enable reliable internal grooving operations within the challenging 6 to 8mm diameter range. Internal coolant-designed holders deliver pinpointed coolant flow directly to the cutting edge, facilitating improved tool life, enhanced machining performance and optimal chip evacuation in confined bores where conventional tooling solutions struggle to maintain stability and evacuate swarf.
The expanded portfolio now encompasses four distinct insert configurations addressing specific machining requirements. The TMIR/L insert handles internal grooving operations with precise groove widths from 0.5 to 2mm, whilst the new TMIR/L-T variant delivers internal turning capability with approach angles of 20° and 47°. The TMIR/L full-radius insert enables complex internal profiling, and the TMIR/L-MT threading insert can process 60° metric threads across pitch ranges from 0.5 to 1.75mm.
Two holder configurations support the expanded insert range. The TMIHR/L steel boring bar series offers cost-effective solutions for general applications with overall lengths of 80mm and reach depths up to 16mm. For demanding applications requiring maximum rigidity, the TMIHR/L-C carbide boring bar range delivers superior vibration damping with reach depths extending to 32mm whilst maintaining the critical internal coolant delivery system.
Recent comparative trials demonstrate the system's performance advantages in production environments. Internal turning trials in alloy steel AISI 4140 material achieved 22% tool life improvement compared with conventional carbide tooling. Separate grooving trials in carbon steel AISI 1020 delivered tool life increases of 50%.
The modular system architecture reduces inventory requirements whilst maximising operational flexibility. Manufacturers can address the complete spectrum of internal machining operations with the toolholder holder platform that is available from 54 to 100mm overall length and easily combines with interchangeable insert geometries to minimise costs and simplify setups. The quick-change insert design enables rapid conversion between grooving, turning, profiling and threading operations without lengthy tool changes or machine downtime.
The complete WINIGROOVE expansion is available with TaeguTec’s renowned TT4430 and TT8020 grades for a wide range of material types.
