From one thoroughbred to another

Mills CNC, the exclusive distributor of Doosan machine tools in the UK and Ireland, has recently supplied precision subcontract specialist Colt Precision with a new large-capacity vertical machining centre. The machine, a Doosan DNM 6700 with the latest Fanuc 0iMP control, was delivered and installed at the company’s 7000 sq ft facility in Tewkesbury in May 2021, and was supplied with a Nikken 5AX 201FA (4th/5th-axis) rotary tilting table.

Since being installed, the DNM 6700 has been busy machining a range of high-precision, complex parts for the medical, defence, aerospace and general engineering sectors, from materials such as stainless steel, steel, aluminium, titanium and plastic.

The Doosan DNM 6700 is a large-capacity vertical machine with 1300 x 670 x 625 mm travels and a 1500 x 670 mm work table. As well as a Nikken 4th/5th-axis unit, the machine was supplied with a Renishaw OMP60 and OTS tool and workpiece probe package for quick and trouble-free in-process inspection and measurements. An MH500 swarf conveyor for high-efficiency chip evacuation also features.

Explains owner and co-director, Simon Tarrant: “The DNM 6700 is a large, powerful machine. It is also extremely rigid, accurate and reliable. All of these attributes make it ideal for machining a range of parts from an equally diverse portfolio of materials.”
In addition to its high specification, other issues impacting Colt Precision’s decision-making process included the machine’s availability, and the aftersales service and support provided by the machine tool supplier.

“Mills CNC has a good reputation in the market for its aftersales service and support,” says Tarrant. “When we placed the machine order it was delivered in double-quick time and, since its installation, hasn’t missed a beat.”

Tooling specialist opts for Ibarmia

Located near the major automotive OEMs in Warwickshire, 2G Tooling Ltd has rapidly built a prestigious reputation for manufacturing everything from fly press tooling through to large drawn tools. To expand the scope of its tool-making capabilities, the Southam-based subcontractor has recently purchased a large-bed five-axis Ibarmia machining centre from Dugard. The Ibarmia ZVH45 L3000 Star has a 3 m bed, a travelling column, a ±105° B axis, a rotary table and capacity for up to 6-tonne workpieces on the bed.

Managing director Chris Peters says: “The main reason we bought this machine was to give us extra flexibility, extra capacity and more size. It is a much bigger machine than we had previously, which we part-exchanged for the Ibarmia. What sold this machine to us was a Zoom meeting with the Ibarmia factory in Spain. The difference between Ibarmia and what I have seen before from most mass-produced machine manufacturers is a bespoke set-up and a family-run ethos. You could actually see production with more time and care being spent on each machine.”

When asked why the company specified the Ibarmia ZVH45 L3000 Star model, Peters says: “This machine will not only give us extra capacity but much greater flexibility. Having the rotary table and the B axis will allow us to machine components that were very difficult previously.

“The flexibility and reach of the machine will enable us to reduce the overhang of tools from 100-150 mm to 30 to 50 mm,” he continues. “This will improve the stability of our tooling, the surface finishes and, subsequently, improve tool life.”

Hurco draws the crowds

Taking advantage of relaxed Covid-19 restrictions over the summer, Hurco Europe was one of the first UK machine tool businesses to schedule an autumn open house, which took place earlier this month. Managing director David Waghorn says: “It was great to welcome everyone back to our facility. Nothing can substitute for meeting people face to face. As efficient as Teams and Zoom calls are, they really can’t replace standing in front of a machine and watching it cut metal.”

It would appear that the Hurco customer community agreed. Visitor numbers and pre-registrations were the best to date at the company’s new UK demonstration facility, which opened in 2019. In excess of 100 people from more than 60 companies attended over the two days. The show marked the launch of the new VM ONE, a super-compact, entry-level machining centre that replaces the VM5i. Also on show for the first time in the UK was the BX60i portal machine, which maintains dynamic stability and accuracy despite having large X- and Y-axis travels.

Webinar highlights Taiwanese innovation

In response to emerging global trends, Taiwan Excellence, supported by Taiwan’s Bureau of Foreign Trade, invited five Taiwan Excellence Award winning machine tool manufacturers to demonstrate their intelligent solutions in a webinar held alongside the recent EMO Milano 2021 exhibition. Within the main section of the webinar, Taiwan Excellence Award winning enterprises introduced their latest smart solutions and technologies.

The companies participating in the webinar included Tongtai Machine & Tool, Fair Friend Enterprise (FFG), Buffalo Machinery (AXILE), L&L Machinery and HIWIN Technologies. Titled ‘Beyond Smart’, the webinar welcomed 48 media outlets and 171 buyers from around the world. This year, a total of 47 Taiwanese manufacturers participated in the physical EMO Milano exhibition, including HIWIN, AXILE and FFG.

Taking die-sink EDM to the next level

To enhance the manufacture of technically challenging moulds from hardened stainless steel, Ledwell Plastics has invested in a new Sodick AD35L spark erosion machine from Sodi-Tech EDM. This advanced die-sink EDM machine provides the speed and accuracy required to reduce costs and enhance precision, while also offering low electrode wear and the necessary reliability to facilitate unmanned overnight operations.

“Our toolroom makes moulds from many different materials, everything from aluminium through to hardened stainless steel,” explains managing director Benn Simms. “Recently, however, we were working almost exclusively with the latter material in the production of very small and intricate moulds, a trend that looked set to continue for some time. The problem was our existing die-sink EDM capability, which was somewhat antiquated, meaning we had issues with accuracy and breakdowns that were impacting project timescales and costing a lot in repairs.”

As a result, Ledwell Plastics sought a new die-sink EDM that could work to tolerances of less than 0.025 mm. In addition, the highly technical, hardened stainless steel moulds require a large amount of sparking, so fast processing speed was another factor high on the wish list.

“We looked at existing spark eroders, but after undertaking some research and speaking to other Sodick users, we settled on the AD35L,” says Simms. “During an on-site demonstration at Sodi-Tech EDM we could see that the machine’s performance was particularly impressive with its high-speed linear motors.

“Our new Sodick allows us to run overnight, unlike our previous machine, which we could never trust in that regard, particularly with blind components/features that are difficult to flush,” he continues. “The high-speed linear technology of the AD35L evacuates the cavities much better with its enhanced flow of dielectric fluid.”
