FEATURE ON CNC LATHES AND TURNING CENTRES

Even faster Nakamura-Tome turn-mill centre

The Nakamura-Tome range of multi-tasking turning centres is renowned for being quick and productive, but now there is an even faster model. The launch of the Nakamura-Tome NTY3-100V now available in the UK from the Engineering Technology Group (ETG) can reduce cycle times by more than 30% over its predecessor.

The new multi-tasking NTY3-100V is the second instalment of the V series, following the WY-100V announced last July. The V series has speed at the core of its design concept, starting with the incorporation of Nakamura’s ChronoCut software. ChronoCut reduces idle time between operations with a multitude of new featuresthat increase production speed, all without changing the machining conditions or impacting machine accuracy. 

As standard, the twin-spindle Nakamura NTY3-100V includes Y-axis capabilities on all three tooling turrets that enhance processing capabilities with balanced left and right spindle machining. Simultaneous upper and lower turret machining further support high productivity levels.


As a three-turret machine, the NTY3-100V can accommodate up to 72 tools. By pre-setting tools for two or three different component types beforehand, there is no need to change tool set-ups for processing a multitude of different workpieces. Moreover, by adjusting the turret balancing time between the left and right spindles and utilising the lower turret for centre support, gains are available in both flexibility and speed.

Nakamura-Tome CEO Shogo Nakamura says: “Many customers want automated processing of precision workpieces while ensuring high and flexible production volumes. On top of that, we’re determined to deliver the clear value of fast cycle time and set-up time reductions. The NTY3-100V provides this, incorporating feedback and opinions from various internal departments and customers in its development.”

Rapid set-ups decide Cincom purchase

Last autumn, motorsport subcontractor h2m needed to replace an ageing sliding-head CNC turn-mill centre at its Hinckley factory. Joint managing directors and owners, father and son team Andy and Martin Forryan, considered buying a replacement from the supplier of the original twin-spindle, 32 mm capacity slider, but insteadopted for a Cincom M32-VIIILFV from Citizen Machinery UK.

Around 3000-off is a large run for sliding-head turned parts at h2m, while the production of batches of relatively simple components up to 500-off is typical for unattended overnight running. However, the company completestrickier jobs during day shifts in batch sizes as low as 10-off, so speed of programming is essential to minimise machine downtime.

Andy and Martin paid particular attention to this issue, concluding that the Cincom lathe with Citizen’s Alkart Wizard programming system would be less expensive and several times faster than if purchasing the other lathe. The wizard assists and simplifies the creation of even complex cycles using a built-in code library, reference material and diagrams.

Sharing some detail of their deliberations, Martin says: “Alkart Wizard is an inexpensive option. We use it to prepare programs and prove them offline for virtually every sliding-head part we produce. We only program the occasional simple component directly at the control.

“Even complicated components take just 30-40 minutes to program in Alkart with only a further 15-20 minutes to check the cycle virtually in the wizard.So a new job is always up and running in under an hour.”

He contrasts this with the much longer and more expensive route that would have been needed with the other slider, for which a similar wizard was not available.

Tornos Swiss XT at micro-machining show

Tornos presentedits Swiss XT at SIAMS 2024 in Moutier, Switzerland last month exemplifying the potential of the machine’s performance in micro-machining operations at small and medium-sized turned-part manufacturers.

Characteristics of the Swiss XT include its ergonomics and compact design, which deliver a minimal footprint and easy access to the three tool systems. Among the aims of these innovationsis reducing maintenance to zero.

With configurations available in eight or nine axes and the ability to use three tools in cut simultaneously, the Swiss XT increases productivity. According to Tornos, the nine-axis version, with its three Zaxes, simplifies complex operations.

The Swiss XT offers up to 48 tool positions, including 18 rotating positions. This capability allows customisation for a wide range of machining processes. The expanded tooling capacity ensures that users can maximise the productivity and efficiency of the machine while meeting complex and diverse production requirements.

Integrated advanced features of the Tornos Swiss XT include Eco Mode to reduces energy consumption and the ACB Plus system for efficient chip management. These advances ensure safer, more sustainable production and underline the commitment of Tornos to both energy efficiency and production safety. 

Also available for Swiss XT machines is the Tornos TISIS software. TISIS simplifies the use of special driven tools, while the integrated Gantt chart facilitates the synchronisation of machine channels. These modules allow operators to master the complexity of the Swiss XT quickly and ensure a smooth transition to this technology.

Start-up makes Lynx its first machine

Mills CNC has supplied Herriott Precision, a precision subcontract start-up, with a new multi-tasking lathe manufactured by DN Solutions.The machine, a FANUC-controlled 8-inch chuck/67mm bar diameter Lynx 2100LSYB sub-spindle Y-axis lathe, arrived at the company’s facility in Worcestershire in April 2024. Mills CNC supplied the machine through its ‘Smart Options’ machine tool rental scheme.

The Smart Options scheme enables manufacturers to ‘rent’ a new DN Solutions machine tool for an initial 12-month period. The initiative is a flexible option for component manufacturers looking to increase and improve their machining capacity and capabilities, without ties to a long-term finance agreement. No deposit is necessary and Mills CNC provides training as part of the package via an agreed schedule of tailored monthly payments. Rental payments are 100% allowable against taxable profits.

Despite being installed just a few short weeks ago, the Lynx 2100LSYB installed at Herriott Precision is already earning its keep machining a range of small, high-precision, complex parts for a range of customers.

The Lynx 2100LSYB at Herriott Precisionalso features a number of options and accessories.These include a high-efficiency Filtermist oil mist extraction unit, a MH500 swarf conveyor and bin, Hainbuch collet chucks and a Hydrafeed MSV65 servo-driven bar feeder with an integrated bar support unit.

Says owner and directorJoshua Herriott:“To date, we’ve only used our Lynx 2100LSYB for chucking work. However, the integration of a bar feeder enables us to take on new, higher volume work and, where feasible, run the machine unattended to achieve improved productivity and process efficiencies.”

He adds: “Throughout the whole process, Mills have been very supportive and proactive; exactly what was required to help me get the business up and running.”
