Turbine Machining Days 2020: Okuma and Partners to nnovations for optimised precision machining processes
Innovative event concept to beat the challenges of coronavirus
From 29–30 September 2020, Okuma Europe GmbH is opening the doors of its European headquarters in Krefeld, Germany, for the Turbine Machining Days 2020.
In compliance with the hygiene measures required due to the coronavirus, visitors will see the latest process optimisation developments for turning and milling turbine parts, with particular emphasis on precision machining, presented as a ‘tour of the stations’. The event will be run in cooperation with two partners whose solutions contribute to the effectiveness of the Okuma machines: Tool manufacturer EMUGE-FRANKEN and the software supplier OPEN MIND Technologies AG.
In a year where virtually all trade shows and events have been cancelled, Okuma is venturing to take the step of running a physical event: “Our customers really appreciate seeing the machines and being able to exchange views on the technology in person. They haven’t been able to do this for a long time, which is why we are now offering them this opportunity. Of course, we are aware of our responsibilities and have developed a new concept that ensures the safety of both our guests and our employees”, says Norbert Teeuwen, managing director of Okuma Europe GmbH.
In line with social distancing and hygiene regulations, visitors will be divided into small groups and guided from station to station. Representatives from Okuma, EMUGE-FRANKEN, and OPEN MIND will be giving presentations there, combined with live demonstrations directly on Okuma machines. Between changing the groups, the individual stations will be carefully disinfected to create optimum conditions for all participants. There will also be culinary breaks and, here too, the customers will be surprised with something special.
Technologies for the best surface quality
At three of the five stations, visitors will experience directly on Okuma machines how solutions from Okuma’s partners can accelerate precision machining processes and optimise the surface quality.
Using the Multus U4000 multitasking machine, two processes – conventional programming and innovative 5-axis tangential processing – will be compared using the hyperMILL® MAXX Machining finishing module performance package, combined with conical barrel cutters made by EMUGE-FRANKEN.
The focus of the MU-8000V is on reducing work steps and setup times. Complete machining of the component is demonstrated on a machine using a turbine disc as an example. Here, guests will witness the use of PAGODE milling cutters, 2.5D milling, 5-axis drilling, deburring and feature machining.
The GENOS M460-5AX 5-axis vertical machining centre and the hyperMILL® impeller blisk package are used to show how these complex components can be programmed quickly and easily.

NCMT wins machining centre agency
Following its appointment by Rema Control as sole agent for the UK and Irish markets, NCMT will show at MACH 2020 a 5-axis NBT5.25 machining centre
With immediate effect, NCMT has been appointed sole sales and service agent in the UK and Ireland for the range of vertical machining centres (VMCs) manufactured by Rema Control at its factory in Stezzano, near Milan, Italy.
Founded in 1987, the company is a member of UCIMU, the Italian Association of Machine Tool Manufacturers, specialising in building large, 3- and 5-axis, moving-column machines with travels up to 8,000 mm in the X-axis and 1,200 mm in Y. The manufacturer also produces trunnion-type 5-axis VMCs, ultra-rigid universal milling machines with box ways, and gantry-type VMCs with a rotary pallet changer.
The long-bed machine programme, which fills a gap in the NCMT range, is particularly well suited to production applications in the energy, shipbuilding and other heavy industrial sectors as well as in the mouldmaking and aerospace industries.
At MACH 2020 (Hall 19 Stand 130), NCMT will be showing for the first time a moving-column machine from the principal’s Newton Big range, a model NBT5.25 with linear travels of 2,500 x 800 x 800 mm capable of simultaneous 5-axis metal cutting. The two other CNC axes are provided by a flush rotary table for 360-degree positioning and a ± 92 degree B-axis spindle head. A 10,000 rpm spindle delivers 22.5 kW of power and 190 Nm of torque (optionally 33 kW / 260 Nm), while the integral motor spindle alternative is rated at 12,000 rpm / 38 kW / 268 Nm.
Capable of heavy-duty machining, the BT40 / HSK-A63 machine supports 1.5 tonnes on its rotary table or 1 tonne/m2 over the 2,800 x 820 mm fixed table area. Rapid traverse in the linear axes is 50 m/min and installed weight is 15 tonnes. The machine on show will be controlled by a Heidenhain TNC640, although Siemens and Fanuc CNC systems may be specified.

NCMT to hold gear machining event
A one-day seminar and Open House on the manufacturing of gears will be held at NCMT’s Coventry technical centre and showroom on 9th July 2019. A variety of production methods will be demonstrated on Japanese-built Makino and Okuma machining centres as well as on one of the latter manufacturer’s multi-tasking turn-mill machines.
Methods covered will include hobbing, power skiving and InvoMilling, with the capability to produce different gears using the same standard machine platform. Gear grinding will also feature, involving the use of NCMT’s proprietary EasyGear grinding software. Other techniques on show will be both wire-cut and ram-type production solutions on Makino electric discharge machining equipment.
The main message during the event will be the flexibility, high productivity and relatively low investment cost offered by producing external and internal gear types on 5-axis machining centres, multi-tasking lathes and EDM machines, coupled with the short lead-times and high levels of accuracy and repeatability that are achievable.
Another focus will be inspection of the gears to verify their accuracy. This will be done in-cycle via a touch probe on an Okuma Multus multi-tasking lathe and off-line inspection on a Hexagon Metrology Leitz CMM equipped with Quindos software.
Rounding off the exhibits will be an automated system configured for gear blank production based on an Okuma Genos L3000 lathe fitted with a Cellro robotic system from Holland for automatically loading billets and unloading components.
