ETG presents agile Axile G8 machining centre

The Engineering Technology Group (ETG) is introducing the new G8 machining centre from Axile. Since entering into an agreement with Axile to become the exclusive UK and Ireland technology partner, ETG is already enjoying a significant level of enquiries for the range of five-axis VMCs, heavy-duty double-column machining centres and mill-turn machine tools.

With a maximum loading capacity of up to 1300kg on a swivelling rotary table, the agility of the G8 enables the production of various large components. Also in the G8 Series is the G8 MT. This machine option offers both milling and turning in one machine, increasing operational flexibility, reducing set-up times and offering the potential to machine a wider variety of parts in a single set-up.

Axile builds the flexibility of the G8 and G8 MT upon a high-quality cast base that offers a structural foundation which optimises vibration damping and limits thermal behaviour.From an agility perspective, both models have direct-driven servo motors, double symmetrical and synchronised axes, linear scales with 0.1μm resolution,and double roller type linear guideways – all features that minimise backlash, vibration and elasticity.

Regarding specification, both the G8 and G8 MT offer a table size of 800 mm diameter with X, Y and Z-axis travels of 670 x 820 x 600mm and a maximum feed rate of 60m/min. The swivelling A axis moves to ±120° with a 360° continuous C axis. As standard, the built-in spindle come with a 20,000rpm asynchronous motor supplied with tools from two carousels that offer 32/64 position tool-change capability. The machine can also feature larger magazines with up to 120 positions.

Subcontractor installs large twin-column machine

Having a working volume of 2200 x 1700 x 750 mm, the Hurco DCX22i twin-column, bridge-type VMC with 8 tonne table load capacity is now the largest item of prismatic machining equipment on the shop floor at Jones Nuttall Precision Engineering in Warrington. The machine features a 40-station tool magazine, 12,000 rpm/18 kW spindle and rapids of 32 m/min in the X and Y axes, and 24 m/min in Z.

Jones Nuttall’s new DCX22i brings to 12 the number of machining centres in use on the shop floor, all of them supplied by Hurco, there being eight VM30i models and other VMCs also in operation. Additionally, a third of the lathes on site are Hurcos, both of them bar-fed. The TM10 has a 10-inch chuck while the 8-inch chuck TMM8 includes live tooling and a C axis.

Metals processed include Inconel, titanium alloy, stainless steel, steel, brass, aluminium, copper and even silver. Engineering thermoplastics such as nylon, acetal and PEEK are also common, as well as composites. Batch sizes range from one-offs to runs in excess of 1000.

Founded in 1971, Jones Nuttall has been a Hurco user since 2000, at which time the subcontractor decided to progress from manual tool-change mills to machining centres. The company opted for Hurco equipment due to the high build quality and spindle power of both the machining centres and lathes.

Geoff Brown, a machine operator at Jones Nuttall, says: “Hurco machines are very easy to program, set-up and use. The twin-screencontrol on the DCX really helps as I can program and edit on one screen, while the other screen displays the component and toolpath. The programming of all our Hurco machines is the same, so often one operator can run two or three machines.”

VMC for cost-effective machining of larger parts

Following the success of its M1 entry-level vertical machining centre, DMG Mori has introduced a larger version, the M2, with double the travel in the X axis at 1100 mm. The Y- and Z-axis travels are identical at 550 and 510 mm respectively, but maximum table load is nearly treble that of the M1, at 1700 kg.

The M2 retains the same fixed-table, travelling-column design, which minimises wear on the machine’s ballscrews and drives by not having to move the heavy table with its load to the spindle. Measuring 1400 x 600 mm, the clamping surface is sufficient to accommodate one large part or multiple smaller components set up in various fixtures (and even a 4th axis indexer) at the same time.

DMG Mori’s monolithic design of the thermally stable machine bed casting, which weighs 3400 kg, gives the M2 high rigidity and good damping properties. Minimal vibration, even when taking heavy cuts, protects the machine structure, provides long tool life and ensures good surface finish on machined components. The total installed weight of the machine is nearly 7 tonne in a compact footprint of only 7.3 sq m.

Users benefit from the choice of a 10,000 or 12,000 rpm inline spindle, of which the company has installed more than 4000 units worldwide, as well as a 24-pocket tool magazine and rapid double-gripper tool changer.

The M2 has roller guideways in all axes and machining dynamics are constant regardless of workpiece weight, report DMG Mori. A 20-bar internal coolant supply is optional. Control is via Siemens Sinumerik One touchscreen CNC, which has very few buttons, making it ideal for the new generation of setter-operators familiar with smartphones and tablets.

Factory of the Future continues with TPR

True Position Robotics (TPR)says it has been chosen by BAE Systems to continue working on current and emergent projects as part of the latter’s ‘Factory of the Future’. Moving forward, further work will define and develop the future Industry 4.0 connectivity, system maturity and scalability. Martin Knott, Factory of the Future technology team lead, says: “We will work with TPR to continue our developments and integration of their technologies along with newly selected hardware. TPR is one of over 50 key partners who are collaborating with us and share the vision of our developments for UK manufacturing.”

TDI Challenge shows spirit of innovation

The Technology, Design and Innovation (TDI) Challenge competition organised by the Manufacturing Technologies Association (MTA) has continued to showcase the imagination and design skills of a new generation of young engineers.The TDI Challenge 2023 encouraged students between 16 and 18 years old who are enthusiastic about engineering and science, to demonstrate their creative talent to an industry that relies upon vision and innovation.

Finals day took place at the Yamazaki Mazak facility in Worcester, where shortlisted entrants got the opportunity to pitch their idea to a judging panel chaired by Stewart Lane of metrology specialist Renishaw. This year’s winner was Bhavy Metakar, of Westcliff High School for Boys in Essex, who showcased his innovative take on a bionic arm.
