Now available from Ward CNC are the Hartford SW216 and Hartford LG500 machining centres. Suitable for larger capacity work, the Hartford SW216 is a double-column, bridge-type travelling-table VMC with a 2 x 1.45 m table that can support the machining of parts up to 7000 kg. With X, Y and Z-axis travel of 2 x 1.6 x 780 mm, this 50-taper spindle workhorse has an 18.5 kW spindle motor for heavy cutting operations, regardless of material type.

Ward CNC says that the SW216 offers a blend of flexibility, rigidity and performance for the machining of large components. From an optional perspective, the machine is available with 22 or 26 kW spindle motors, a 32, 40 or 60-position ATC, and the choice of FANUC, Heidenhain or Hartrol Plus CNC control.
Also available is the Hartford LG500. Pitched as a high-quality, robust and capable three-axis machining centre, the LG500 has a competitive price point. With a 24-position ATC, an 8000 rpm high-torque 5.5 kW spindle motor and a BT40 spindle taper, Ward CNC says the Hartford LG500 is suitable for any machine shop.
Available with a FANUC or Hartrol Plus CNC interface, the Hartford LG500 is offered with a list of options. The Hartrol Plus interface has a 19” touchscreen control with an ergonomic angular operation panel. Behind this configuration, is the facility for five groups of value-added app, which include program management, operational assistant, machine monitoring, utilisation rates and maintenance support, all with an array of options that ensure ease-of-use and high functionality.

The tool-making division of Gateshead-based TDX, which supplies services and tools to the thin-film plastic thermoforming industry, mainly for food packaging applications, has started to automate its machine shop. The latest purchase is a German-built Hermle five-axis machining centre with a 20-pallet storage system installed by UK agent Kingsbury, which is now working 24/7.

Two members of the management buyout team that purchased TDX in 2013, Neil Atkinson and David Renton, were especially pleased to progress the investment. Five-axis machining was usually the bottleneck at the 24,000 sq ft tool-making facility, and it normally fell to the two directors to go into the factory two or three times on both Saturday and Sunday to change over five non-automated five-axis machining centres.
Since the Hermle C250 with linked HSFlex automated pallet change system entered production, weekend visits have been unnecessary. Each aluminium thermoforming mould billet is pre-machined on one face and then milled on the other five sides internally and externally in one operation in from four to six hours. So 20 pallets equates to an average of 100 hours’ machining on the Hermle, which is more than enough to keep the production cell busy non-stop from Friday afternoon to Monday morning.
Atkinson says: “The automated milling cell has not only eliminated manual intervention at weekends, but requires minimal attendance during the week, releasing the operator for other tasks. We approached six potential suppliers, all of which carried out machining trials. Kingsbury demonstrated the fastest cycle time on the Hermle, approximately 10% quicker than the best of the others. Surface finish was also better.”

Underlining its commitment to the British machine-tool industry, Yamazaki Mazak has launched its latest simultaneous five-axis machining centre – the CV5-500 – which will be the only machine in its class to have been completely conceived, designed and built in the UK. The CV5-500, which is currently being manufactured at Mazak’s Worcester plant, is being marketed at a highly competitive price point, making it suited to subcontractors, start-ups and job shops.

Mazak’s versatile five-axis machine features a high-rigidity bridge construction and a fully supported travelling trunnion table.
“While the numbers of British machine-tool builders have dwindled over time, Mazak has continued to invest in its UK R&D and production facilities,” says Alan Mucklow, managing director UK & Ireland sales and service division at Yamazaki Mazak. “The CV5-500 is the latest in a long line of Mazak machines to have been fully designed and built in Britain.”
Mazak’s CV5-500 features a newly designed constant overhang headstock to maintain machining rigidity, even at the full extent of the Z-axis stroke. The machine is equipped with a 12,000 rpm spindle offering 18.5 kW and 119.4 Nm, making it suitable for a range of materials. An optional 18,000 rpm spindle, which includes core cooling through the X-, Y- and Z-axis ball-screws, is available for high-speed applications.
The CV5-500 is equipped with a high-rigidity Sankyo table, driven with roller gear cam that provides a wide angle of rotation, specifically 220º in the B axis and 360º in the C axis. The CV5-500 delivers agile performance, with rapid traverse rates of 36 m/min in the X, Y and Z axes, and can process workpieces up to 500 mm in diameter by 320 mm tall, and up to 200 kg in weight.

After experiencing ongoing problems with the bearings on a vital milling machine at a steel plant, the management team turned to NSK for a solution. This decision proved to be extremely lucrative, with the steelmaker now enjoying annual savings of €35,600.

The steel facility produces rails for lift equipment that require the machining of two flat areas at the ends, which assist the fitting of the rails during assembly. While the time required to mill these rough surfaces is short, the stiffness of the machine’s spindle is critical due to the length of the rails. However, using the milling machine’s original bearings, the steel plant noticed that spindle stiffness reduced after just three months, making it necessary to change the spindle assembly, including motors.
Faced with a recurring and expensive situation, NSK was asked to find a solution. Expert NSK engineers visited the plant and analysed the spindle design as part of its AIP Added Value Programme. Following their analysis, it was recommended that the spindle be redesigned with a four row bearing set, instead of three, thus increasing the radial load capacity and radial stiffness. The contact angle was also changed from 15° to 25°, to increase the bending stiffness of the shaft.
NSK’s high precision angular contact ball bearings (ACBB) were selected from its range of standard products.
After the steel plant had implemented the change, the bearings continued working in the milling machine for more than 12 months, with no failures experienced in the motor or transmission. Today, the steelmaker no longer has to endure four production stops a year, while the costs for the replacement spindle assemblies and motors have also been eliminated. Taking these factors into account, it has been calculated that the plant is
saving €35,600 per annum.

Mills CNC, the exclusive distributor of Doosan machine tools in the UK and Ireland, has supplied Hertfordshire-based precision subcontract specialist Qualiturn Products with a Doosan DVF 5000 five-axis machining centre.

The machine, one of the first in the UK, was installed at Qualiturn’s modern and spacious 20,000 sq ft facility in February 2019, and was timed to coincide with the company’s relocation to these new premises.
Says Nick Groom, Qualiturn’s managing director: “We operate a high-productivity, highly-efficient and flexible milling cell that runs 24/7 and provides customers with high-quality, competitively-priced machined components, delivered in double-quick time. The DVF 5000 investment was made to improve our milling capabilities and complements our existing technologies.
“We are keen advocates of one-hit machining and, wherever possible, look to automate our processes,” he adds.
This commitment to continuous improvement through automation led Qualiturn (in 2014) to invest in its first Lang Robo-Trex robot system. The system uses mobile trollies which are loaded with multiple vices that hold workpieces. These workpieces – when prepped – are loaded into the Doosan DNM 650 machining centre by the system’s robot.
Such has been the success of the DNM 650/Lang Robo-Trex automated manufacturing cell that the company decided to invest in a second cell based on the new DVF 5000.
Says Groom: “Our new cell is fully operational and runs 24/7. The Doosan DVF 5000 is a high-performance machine and, by integrating it with an automated parts-handling system, we’ve been able to exploit its full potential. As a result we have experienced dramatic productivity gains and significantly reduced lead times, both of which make us more competitive.”
