Complimentary Tech Day for Advanced Blisk Manufacturing Techniques

Published on: 

The event will provide insights into blisk milling strategies and showcase live demonstrations of manufacturing technologies by Concepts NREC, Emuge-Franken USA and Grob Systems.

Concepts NREC has disclosed that in conjunction with Emuge-Franken USA and Grob Systems, it will host a free Tech Day on June 7th, 2023, at the Emuge Technology Center in West Boylston, MA. Running from 10:00 a.m. to 1:00 p.m. ET, the event will facilitate attendees' understanding of blisk manufacturing milling strategies. Additionally, the session will feature live machining demonstrations utilizing the GROB G550a 5-Axis machining center, equipped with Emuge Circle Segment milling tools and programming by Concepts NREC MAX-PAC CAM software, tailored for turbomachinery applications.

Industry experts will showcase and explicate crucial advanced techniques for productive blisk machining, which includes reducing the finishing time via Emuge Circle Segment (conical barrel) cutters and MAX-PAC CAM strategies. The Circle Segment end mills can curtail finishing times for parts featuring complex geometric contours such as blisks, according to a company spokesperson. Moreover, high-speed roughing solutions using MAX-PAC’s UPASS trochoidal strategy, multi-depth mixed milling strategy to improve accuracy and reduce chatter, and MAX-PAC’s finishing blending strategies to eliminate witness lines on the blade will be presented.

The Grob G550a 5-Axis machining center, characterized by high accuracy and maximal stability, will also be demonstrated. This center encompasses a distinctive machine concept that includes a horizontal spindle position enabling a long Z-travel path and optimal chip fall management. Its arrangement of three linear axes ensures maximum stability by minimizing the distance between the guides and the machining point. The machine also facilitates 5-sided machining, as well as 5-axis simultaneous interpolation, thanks to three linear and two rotary axes with a swivel range of 230 degrees in the A-axis and 360 degrees in the B-axis.


Emuge-Franken USA, a wholly-owned subsidiary of the German company Emuge-Werk Richard Glimpel GmbH & Co. KG, offers technical support to end-users through a network of field engineers and in-house product specialists. The U.S. and Canadian Headquarters in West Boylston, MA, stock over 10,000 types of cutting tools and accessories.

Grob’s portfolio includes several universal 5-axis machining centers and a range of automation solutions. The Grob U.S.A. facility in Bluffton, Ohio employs over 750 staff members and provides support to Grob customers across North America.
