Next-generation Puma DNT lathe series unveiled

Mills CNC, the exclusive distributor of DN Solutions and Zayer machine tools in the UK and Ireland, has introduced a new range of high-performance, box guideway lathes into the market. The next-generation 8-10” chuck (67-81mm bar diameter) DNT Puma 2100/2600 lathe series is inherently flexible and provides manufacturers with capacity up to 460mm turning diameter and 658mm turning length.

The new series comprises of eight models in total.Fundamental to performance is their rigid design and build, which boasts box guideways on all axes to help prevent vibration and, as a consequence, ensure high part accuracies, long tool life and improved surface finishes even during heavy-duty machining operations.

Spindle power and speeds vary (up to 26 kW and 4500rpm) and are model dependent. A high torque option (378Nm) for the DNT 2100M lathe is also available.

DNT lathes feature 10-12 station servo-driven turrets for fast (0.15 second indexing time) and accurate tool selection: driven tooling models are supplied with the rigid BMT 55P or 65P (base mounted) turret that can accommodate 5.5 kW/6000-10,000rpm rotary tools and facilitate fast and precise milling, drilling and tapping operations.To ensure the machining of longer workpieces, DNT lathes are equipped with manual, programmable or servo-driven tailstocks.

The new lathes feature the FANUC iPlus control with 15” touchscreen iHMI that is both intuitive and attractive.

Says Tony Dale, Mills CNC’s CEO:“New DNT 2100 and 2600 lathes are now available.Their impressive technical specification will, I am confident, have a universal appeal among component manufacturers looking to increase their productivity and deliver ‘right-first-time’ turned parts to their customers.”

Global machine tool market set for growth

The machine tool manufacturing industry is facing a transformative decade, and as manufacturers’ needs become more digitally focused, machine tool builders must evolve their products to meet changing market requirements. According to global technology intelligence firm ABI Research, the worldwide machine tool market will grow by a CAGR of 4.3% from 2022 to 2032 and reach US$245.2bn in manufacturing value added.

“This growth is driven by new product design facilitating the need for new machine tools, old equipment reaching the end of its lifecycle and requiring replacement, and new machine tool solutions being provided and incentivising upgrades,” explains James Prestwood, industrial and manufacturing research analyst at ABI Research.

Longevity of lathes prompts repeat purchases

It is often said that a subcontractor does not know what type of work will be coming through the door tomorrow, so needs versatile machine tools to produce a wide variety of components. With this thought in mind, the mainstay for production of a large proportion of turned parts at contract machinist Repro Engineering are CNC turning centres from Citizen Machinery, both Miyano fixed-head lathes and Cincom sliding-head models.

The first Miyano to arrive (in 1997) was a BND42S twin-spindle lathe with live tooling. It departed just three years ago after 23 years of service, having produced more than 2 million components, most in one hit and a large proportion in lights-out operation. The second Miyano, a BND51S, arrived in 1998 and was sold in mid-2022 after an even longer period on the shop floor.

Repro Engineering’s owner and managing director Richard Palmer says: “We have a policy of regularly reviewing our capacity and keeping plant up to date. In the case of the Miyanos, however, earlier exchange simply wasn’t necessary, as the machines continued to hold tolerance.”

The replacement for the BND51S was a more capable BNJ-51SY, which arrived in May 2022. Featuring two turrets and Y-axis movement of the main turret, the lathe facilitates complex machining operations at the main and sub spindles simultaneously. Nine Miyano machines have been purchased over the years.

Regarding Repro Engineering’s sliding-head capacity, the subcontractor operates three Cincom lathes capable of machining parts up to 32 mm diameter bar. Impressed with the quality and longevity of the Miyano machines, Palmer decided to approach Citizen for larger Swiss-type lathes capable of producing bigger diameter, often shaft-type components. He purchased a Cincom A32-VII in 2009, followed by a more highly specified M32-VIII with a B-axis in 2013, and another A32-VII two years later.
