The new SwissNano 7 is now available in the UK from Tornos. Previously only offered in a 4 mm diameter variant, the 7 mm capacity SwissNano 7 retains the advantages of the 4 mm model, such as the kinematics and thermal stability, to deliver high performance and precision when machining small turned parts.

Notably, the original machining capacity of 4 x 28 mm has been boosted to 7 x 50 mm, while spindle power has more than doubled (to 2.5 kW) to machine bars from the hardest materials. According to Tornos, the small footprint and machine design means SwissNano 7 occupies the same space as a cam-type machine and can therefore increase output per square metre compared with other CNC machines.
The six-axis kinematics offer numerical adjustment of all tool positions in the X, Y and Z directions. At the heart of the concept is the back spindle mounted on three linear axes, which makes the machine extremely user friendly. The main platen includes three positions for the rotating tools; it can hold transverse drills, a polygon tool or a gear-hobbing tool. This capability opens up the potential of machining operations not previously possible on this range.
Tornos’ SwissNano 7 is suitable for the medical sector when complemented with the addition of a thread-whirling unit. This attachment enables the machine to be used for the production of maxillofacial screws, and can prove a good partner when it comes to the machining of screws for dental implants or straight implants. The machine can also be equipped with high-frequency spindles for back-machining operations, which allows the machine to mill hexalobular (Torx) shapes.

A new range of CNC turning centres with live tooling in the turret has been introduced by Hurco. The three models – TM8Mi XP, TM10Mi XP and TM12Mi XP – cover the 8-, 10- and 12-inch chuck sizes required by most manufacturers.

Hurco previously sold a range of driven-tool lathe models designated TMM, but their performance was limited as they were not controlled by the proprietary Max5 control that has proved so popular on the company’s machining centres due to features such as concurrent programming and recovery restart.
The new lathe control system, an in-house development by Hurco’s software engineers, was first introduced on the XP-series of two-axis lathes in early 2018. This all-digital control platform was delivered alongside improvements to the design of the machine, including a smaller footprint, roller guideways in the linear axes, a larger spindle bore and enhanced rigid tapping.
A primary reason for developing the TM Mi XP range, in addition to adding the superior features of the Max5 control, was to ensure that driven-tool milling is smooth and accurate. The machines include a servo-controlled C axis and the capability to deploy driven tools at all turret positions, allowing milling and off-centre drilling to be performed in addition to normal turning operations.
Two machines are currently in the UK, a demonstration model at Hurco in High Wycombe and another on trial at a customer’s factory. The first machines available for sale will arrive later this month. These models will be the new 8-inch chuck version which, compared with the former TMM lathes, offer higher spindle power at 22.6 kW, a spindle bore increased from 62 to 79 mm, a draw tube diameter of 64.5 mm (up from 52 mm), and faster rapids at 30 m/min (previously 24 m/min).

Sheffield-based Gripple has enjoyed a 50% increase in tool life and 44% reduction in downtime on its Star sliding-head CNC lathe by installing a MicroMag magnetic filter from Eclipse Magnetics.

In order to satisfy its environmental commitments, Gripple was keen to maximise efficiency and reduce waste on the lathe, which included exploring ways to prolong coolant life and enable the coolant flow system to work as efficiently as possible.
Since installing the MicroMag, the build-up of swarf material in the bottom tank of the Star machine has been significantly reduced, while the coolant flow system is working more efficiently due to the reduction in swarf circulating in the coolant. In contrast, before the addition of the MicroMag, the bottom tank of the CNC lathe needed to be cleaned approximately every month. There has been such a significant reduction in swarf collecting in the tank that it now only needs cleaning every 50 days. As a result, Gripple can reduce the frequency of cleaning from 12 times per year to just over seven. In addition, the bottom tank previously took approximately 45 minutes to clean, but has since reduced to just 25 minutes.
The tool change data is also impressive since the installation of the MicroMag. For example, on some tool locations, the number of EN1A (leaded) steel components produced has increased by 50% before the tool requires replacement; from 10,000 to 15,000 parts.
Gripple employee Jake Slaughter says: “The MicroMag is a great addition to the lathe and really improves the way it runs. In the long term, I estimate that the company will be able to produce a lot more components with MicroMag units installed on all of the machines.”

Now available in the UK from NCMT, the Okuma Spaceturn LB3000 EX II turn-mill centre is equipped with the Japanese manufacturer’s Armroid robotic arm. As a result, the Spaceturn LB3000 EX II is said to be the first in the world with such a feature integrated inside a CNC machine tool.

A trio of different end-of-arm effector options are available for the robot, each one capable of performing different tasks. One is for blasting the cutting zone with air to improve chip management. Another provides additional support during the cutting process to prevent chatter. In combination with a workpiece stacker, the third effector automatically loads and unloads workpieces weighing up to 5 kg. All three are stored within the machine and are changed automatically by the robot.
Although most conventional robotic systems require complex integration and special training for staff, Armroid needs neither. As the robot is part of the machine tool, separate system integration is unnecessary. Using Okuma’s own OSP-P300A control, an operator enters the co-ordinates for the start and finish points. The robot then moves through its motions, with the cycle being generated automatically to avoid collisions. In addition to automated running under program control, manual operation is possible via a pulse handle that micro-positions the arm.
Importantly a longer and more powerful robotic arm, Armroid Type 2, will be integrated into an Okuma Multus B250II multi-tasking lathe for high-mix, small-batch billet work. This arm is capable of handling workpieces up to 10 kg and possesses a fourth end effector with a three-jaw workpiece hand.

Essex-based subcontractor TNC Precision Engineering has expanded its sliding-head capacity to facilitate an application for a prismatic component previously manufactured overseas.

With a target cycle time of 3-4 minutes needed for TNC to make the part profitable using aircraft-grade aluminium 7075, the applications department at Star GB was confident that the component could be manufactured within the required parameters. Armed with this knowledge and, despite not being a route TNC would typically consider, the company commissioned a full turnkey package with Star GB. This package would allow the company to hit the ground running following delivery and installation.
The machine identified for the project was one of Star’s most advanced guide bush/non-guide bush models, the SV-38R. This high-specification machine combines the fast processing ability of a traditional platen-type sliding-head lathe with the flexibility of a turret machine to enable simultaneous machining operations. The turret includes an independent Z3 axis, allowing two different features to be machined at the same time using Star’s ‘super-position’ control mode.
Through a combination of utilising the machine’s balanced milling capability, specifically selected tooling and comprehensive process development, the final cycle time achieved was just 3 minutes and 13 seconds.
Director Stephen Westall says: “For this type of component, we would typically be looking at a five-axis machining centre, but from our estimations, they simply couldn’t get anywhere near this cycle time. The balanced milling capability of the SV-38R is a game-changer and it’s going
to open a world of opportunities for us.”
