German machine-tool manufacturer Index has introduced the second generation of its G200 turn-mill centre for the complete machining of components from bar or billet.

Available in the UK through sole agent Kingsbury, the machine offers extensive improvements, including increased turning length, up from 400 to 660 mm, a second lower tool carrier and a higher power milling spindle.
Providing cycle-time reductions of up to 30%, the compact machine offers significantly improved performance in a footprint virtually the same as that of its predecessor. New also is the vertical orientation of the heavily ribbed, low-vibration cast bed, which optimises chip flow and provides more space in the working area, especially for the lower tool turrets. Arranged in mirror image, each has an independent, ±45 mm Y axis, as well as 14 live tool stations rated at 16 kW/16 Nm and 7200 rpm maximum speed.
The identical main and counter motor spindles are fluid-cooled, have a bar capacity of 65 mm and a chuck diameter of 165 mm. Rated at 31.5/32 kW and 125/170 Nm, they provide rotational speeds of up to 6000 rpm.
A notable feature is the upper tool carrier, which has a ±65 mm Y axis and a 360° B axis. On one side there is a tool turret with another 14 positions, and on the other an HSK-A40 milling spindle. The spindle’s drive comes with a considerable increase in speed. Whereas the previous G200 was limited to 2000 rpm, the latest 22 kW/52 Nm version provides speeds up to 7200 rpm.
For maximum productivity, it is possible to utilise all three turrets simultaneously at either the main spindle or counter spindle, without interference.

More than £600,000 has been invested by HPC Services on a trio of Nakamura turn-mill centres from the Engineering Technology Group (ETG).

The company is now operating 45 CNC milling and turning machines at its Ilkeston facility, while the machining side of the business employs 80 of the firm’s 150 workers and has a turnover of £8m.
Now commissioned, the three Nakamura machines (two WT150s and a WT100) are boosting production throughput. The WT150II provides up to 26 kW of cutting power for shaft work with synchronised spindles, while the power of the driven-tool motor is suited to heavy cutting with small tools.
Managing director Paul Cobb says: “The WT150 has twin spindles and twin turrets, which makes it hugely versatile. As a subcontractor you don’t really know what is going to come through the door on any day, so these machines are almost the optimum for us. We mostly use them for making milled parts, in medium-sized production runs from a few hundred to a few thousand parts – that’s the sweet spot for us.
“Our Nakamura machines are incredibly reliable, accurate and very quick,” he continues. “Compared with the machine they’re replacing, which was turning out a part in seven minutes 35 seconds, they can do it in just three minutes 50 seconds. The machines can operate on components up to 65 mm in diameter, which is quite large, and we have linked them up to an automatic rotary conveyor. As a result, we can run them 24-hours a day on aluminium or brass parts, and around 18 hours a day on stainless steel. We just feed the CAD details into the machines and away they go.”

A total of 24 Cincom sliding-headstock CNC bar autos were installed between last summer and the beginning of 2019 by Citizen Machinery UK at one of the two factory units operated by Shannon-based medical component manufacturer, Smithstown Light Engineering.

The major investment followed Smithstown’s receipt of a contract from a multinational medical firm for machining multiple variants of two types of endoscopic device parts from 303 stainless steel bar. Annual quantity is currently 18 million for the production of nine million assemblies.
Managing director Gerard King had identified the business opportunity in 2017 and machined sample parts on a 20 mm bar capacity Cincom L20 installed three years previously to fulfil another contract, which is still running, for turning a 316 stainless steel spindle used in a medical delivery device.
Discussions progressed and, to develop the process further, he decided to buy on-spec a 12 mm bar capacity Cincom L12, which is of more appropriate size for producing the endoscope parts in short cycle times.
Says King: “The first of the L12s started arriving in July 2018, and the last ones were on site by January this year. All are operating 24/7. The lead-time from the customer signing the contract and our shipping the first parts in production quantities was five months. Citizen supported us well during this ramp-up phase.”
All of the latest sliding-head lathes are equipped with Citizen’s patented LFV (low frequency vibration) software, part of the control’s operating system that assists chip breaking when machining materials that tend to generate long, stringy swarf during turning.

Gas spring and damper solutions manufacturer Camloc Motion Control has continued the growth of its manufacturing and product development arm following significant investment in a second CNC lathe.

The DMG Mori Sprint 32|8, worth £175,000, further increases the company’s capacity to manufacture and develop more complex, bespoke products for customers at its Leicester facility.
Engineering director at Camloc Motion Control, Matt Warne, sees the investment in a second CNC lathe as a significant step forward for the business as part of its long-term growth plans: “Following the success we have seen over the past 18 months as a result of our investment in the first CNC lathe, we made the decision to bring forward our acquisition of the second from DMG Mori.”
This latest investment allows Camloc to accelerate new product development, reduce specialist component lead times and further improve flexibility in providing bespoke customer product solutions.
“Investing in the latest technology and machinery means we can take our products to the next level, delivering tailored functionality that meets specific customer needs,” concludes Warne.
The Sprint 32|8 is a small automatic lathe with six linear axes and a C axis that is suited to workpieces measuring up to 32 mm in diameter and 600 mm in length, from a footprint of less than 2.8 sq m. Productivity is boosted with the automatic workpiece discharge function and a workpiece transfer conveyor, which is offered as standard.

Okuma will exhibit at this year’s Paris Air Show (Le Bourget, 17-23 June, Hall 4 E51).

The company has more than three decades of expertise in machining technology for the aerospace industry. Within Okuma’s aerospace portfolio are manufacturing solutions for many workpieces such as turbine components, gear parts, hydraulic valves and landing gear components. Okuma’s range of turn-mill machines, including the MU-V, Multus-U and VTM-YB series, are predestined for aerospace applications, while the multi-tasking Laser EX series is additionally equipped with additive manufacturing capabilities.
Aerospace manufacturers benefit from Okuma’s intelligent technologies, like its Thermo-Friendly Concept, which compensates for thermal deformation. The benefit is dimensional stability during long-term machining operations. Furthermore, with the use of ‘Dynamic Tool Load Control’, costs can be reduced by allowing the use of cheap tooling inserts for machining difficult-to-cut materials like titanium.
Visitors to the Paris Air Show will have the opportunity to discuss the latest technological trends with Okuma experts, and are welcome to experience the company’s IoT solution Connect Plan. This software-based system provides analytics for improved utilisation by connecting machine tools and providing visual control of factory operations and machining.
Okuma traditionally puts a special focus on dedicated applications for the aerospace industry, and maintains three global Aerospace Centres of Excellence in Krefeld (Germany), Charlotte (USA) and Oguchi (Japan). All three facilities offer demonstrations of the specific solutions in operation and are open to interested visitors all year round.
