Transmissions manufacturer opts for Mills CNC

Mills CNC has supplied Sussex-based motorcycle transmission and gearbox design and manufacturing specialist, Nova Racing Transmissions, with a new DN Solutions Lynx 2100LMB lathe with FANUC control and an 8” chuck. The machine has replaced an older Daewoo lathe that, although still working satisfactorily, was slow and cumbersome to use.

Since installation, the Lynx 2100LMB, equipped with driven tooling capabilities, has been put through its paces machining a range of high-precision motorcycle close-ratio gearbox components (input/output shafts, gear blanks, dog rings, collars) in small batches up to 10-off. Customers include teams and riders competing in the British Superbike (BSB), World Superbike (WSBK), Isle of Man TT and Motocross championships, as well as motorcycle OEMs, motorbike racing clubs, and individual motorcycle owners, enthusiasts and engine builders. Components are also made for stock enabling the company to quickly supply customers with spare and replacement parts.

Input and output shafts are made from a tough and durable motorsport steel alloy supplied to Nova Racing in pre-cut rough bar stock from steel specialist, Bohler Steels. Following machine set up, soft turning operations undertaken on the Lynx 2100LMB start by first reducing the diameter and length of each pre-cut bar. With 50 mm diameter bars, for example, typically 1 mm is taken off the OD and 3 mm off the length. Other operations prior to heat treatment include gun drilling on each shaft’s centre line using high-pressure coolant to create a long narrow through bore hole with a high depth-to-diameter ratio.

There can be up to six soft turning operations performed on each shaft before heat treatment. Cycle times are short at 2-3 minutes.

Citizen unveils eco-friendly sliding-head lathes

For machining parts from bar up to 20 mm in diameter (optionally 25 mm), a third generation of the Cincom L20-LFV series of sliding-head lathes with a considerably uprated specification has been launched by Citizen Machinery UK. Now offered in five variants, VIII, IX, X, XII and XIIB5, the L20-LFV is a best-selling model with platen tooling as well as front and rear tool posts. All stations feature driven and static positions on the top three models, which also have additional Y-axis movement of the sub-spindle.

Simultaneous five-axis control for performing complex machining cycles is supported on the top two models, one of which has a B-axis tool post with optional ATC (automatic tool change) for tools up to 30 mm in diameter. Chip-to-chip time is 4 seconds. Cutters are driven by a 2.2 kW motor at up to 12,000 rpm, so even small diameter mills are capable of productive metal removal rates.

The Japanese manufacturer says it was the first to offer B-axis ATC on a sliding-head lathe to extend the machine’s versatility when executing angled cross-working or end-facing operations. The magazine accommodates 12 tools, while a 13th is fixed in the upper position on the live tool unit.

Another feature contributing to the lathe’s versatility is the ability to switch over quickly between Swiss-type operation and non-guide bush turning for more economical production of shorter components. This mode results in less bar wastage due to the shorter remnants.


The machine incorporates Citizen Machinery’s Eco II suite of energy-saving features, designed to optimise power consumption, reduce compressed air usage, minimise CO2 emissions and promote environmentally friendly manufacturing practices.

Multi-tasking lathe streamlines manufacturing

Whether for food, beverages, pharmaceuticals, chemicals or water, anywhere liquids are processed will typically see a separator or a decanter at the heart of production. At GEA Westfalia Separator Group’s largest production site in Oelde, Germany, where 1900 people are employed, 120 centrifugal separators are produced every month with the help of 15 machine tools supplied by DMG Mori. These include turn-mill centres and five-axis machining centres and with a high degree of process integration.

One of the latest machines to be installed is a CTX gamma 3000 TC multi-tasking, twin-spindle, B-axis CNC lathe with MATRIS robotic loading and unloading, which supplies spindles to the drives production department in Oelde.

Various spindles undergo production, requiring combinations of turning, gear milling, deep-hole drilling, grinding and in-process measuring. The previous production route involved separate milling machines, turning centres and a cylindrical grinding machine, so work-in-progress and inter-machine handling were inherent in the process. The CTX gamma 3000 TC integrates all of the processes, including grinding, into one work area. Throughput times are considerably shorter and the original machines are free to perform other production tasks.

“The biggest advantage is the fully automated production of entire batches,” says Dennis Hartmann, head of industrial engineering in the Separators Business Unit. “The MATRIS system is designed to be served via four component pallets that are wheeled by pallet truck in and out of the loading area. The robot takes the raw parts and aligns them so that they can be clamped correctly in the chuck and steady rest. The finished parts are then placed back on the pallet.”

New tech centre for CMZ in Haute-Savoie

Spanish Lathe manufacturer CMZ has consolidated its presence in France following the acquisition of industrial premises in Haute-Savoie. After opening its subsidiary CMZ France 20 years ago in Isère, this new space will be used to provide direct technical support, delivery of parts and advice on applications for CNC lathes. 

Part of CMZ’s international expansion strategy, the new technology centre will have a team of aftersales technicians to provide assistance in the area, as well as sales engineers who will offer direct advice for all customers. The facility will also house an applications engineering service and stock spare parts available on short lead times.

The facility’s permanent showroom for customers will display the full range of CMZ products and host technical workshops demonstrating the capacities of the lathes.

Benoit Branchu, a professional with a long career in the industrial sector will be heading the project. Throughout his career, Branchu has held a variety of posts which have given him in-depth knowledge on the use and operation of lathes, as well as a solid vision of the machining world. He did not hesitate to take up the lead in this new adventure in which Branchu is supported by a team of aftersales technicians for direct assistance.

Haute-Savoie is a strategic market for CMZ because the Arve Valley is recognised as the epicentre of precision turning in France and worldwide. The company has been operating in the area for just over a year and with this move is seeking to strengthen its presence with a strong, solid sales structure.

Lynx lathe chosen to machine new products

Mills CNC has recently supplied Alwayse Engineering, a ball transfer unit (BTU) design and manufacturing specialist, with a new two-axis lathe manufactured by DN Solutions. The lathe, a FANUC-controlled 8” chuck/65mm bar diameter Lynx 2100B, was installed at Alwayse Engineering’s manufacturing facility in Birmingham in March 2025. As part of the investment package, the machine was supplied with a HydraFeed MSV65 short magazine bar feeder to facilitate unattended production, and a HydraFeed Rota-Rack parts accumulator and handling system with integrated belt conveyor.

Since installation, the Lynx 2100B has been put through its paces machining single-piece carbon steel bodies for the company’s re-designed and “soon-to-be launched” 805 series BTUs. Of low-profile, high-load capacity and heavy-duty design, the 805 series is primarily for air cargo movement applications.

Alwayse Engineering’s 805 series unit bodies measure 62 mm in diameter and 34.5 mm in length, with machining taking place in a single set-up on the Lynx 2100B. Machining operations include (front end) rough and finish boring of the bodies’ interiors to produce the desired internal ‘hemisphere-shape’, and (back end) burr-free, parting-off operations to cut off the machined parts from the remaining bar stock.

Part cycle times are short at approximately 80 seconds and, once machined on the Lynx 2100B, the bodies are finish machined on one of the company’s other Lynx lathes where a series of multi-dirt exit holes are produced on the bottom of every unit.

Says Richard Cutler, engineering manager at Alwayse Engineering: “DN Solutions and Doosan machines are proven performers and have significantly improved our in-house machining capacity and capabilities. Our Lynx lathes deliver the accuracy, repeatability, fast processing speed and machining flexibility we need to increase productivity.”
