body styles, new insert geometries and grades, and a split case design for large diameter bodies that reduces spindle bearing loads - carbide face milling insert

End of year celebration In November 2016 TaeguTec South Africa held its traditional ‘End of Year’ get together for clients, suppliers and friends. Featured below are a selection of the over 300 attendees.

Cutters are available in end mills (ø32mm), modular types (ø25-40mm) as well as face mills (ø40-80mm) and all are coolant capable for easy chip evacuation.

Furthermore, both lines are available in standard and special grades. The special grades are made for any machining environment, even under harsh conditions due to their high wear resistance and toughness capabilities.

TaeguTec has launched two new five-cutting edge insert lines – RTMX and RTHX – with related cutters specifically dedicated for the stainless steel and difficult-to-cut materials used, but not exclusive, in the aerospace, oil and gas and power generation industries.

Concerning productivity, TaeguTec’s tests using the ChaseMold RTMX line on an aerospace engine case made from Waspaloy and Inconel 718 increased productivity by 65 per cent on a leading competitor’s similar offering.

Sumitomo Electric Hardmetal has expanded its DGC double-sided insert face milling cutter body range to accept SNMU square eight corner inserts or more economical 16-corner ONMU type in the same body pocket.

Both inserts come in 10mm and 12mm sizes and their chip formers are available in three types: MM, ML and MLL. The MM chip former is recommended for unstable conditions, the MLL for stable conditions and the ML covers the middle range between the MM and MLL types.

For tool life during the roughing operation of the airfoil, shroud and the root part of the blade component made from martensitic stainless steel (X20Cr13, AISI 420), TaeguTec’s new 5-teeth RTMX line outlasted a leading competitor’s tool by 65 per cent, while on a blade shroud and root roughing operation made from stainless steel (1.4923), the same RTMX line increased tool life by almost 30 per cent, the company claims.

The RTMX is a press-to-size type line for economy while the RTHX ground type is dedicated towards high precision machining with both line’s offering a high positive rake angle for low cutting resistance.

ChaseMold’s RTMX and RTHX inserts including the line’s optimal cutter design were born through rigorous trial and error as well as performance testing in order to attain excellent performance in stainless steel, difficult-to-cut materials and turbine blade machining under severe machining conditions and in unstable fixtures.
