HER MAJESTY QUEEN ELIZABETH II – 1926 – 2022

The whole team at MTI was deeply saddened to hear of the passing of Her Majesty The Queen. She was a great supporter of industry throughout her reign. Indeed, Her Majesty inaugurated many UK engineering projects, including the Channel Tunnel and the Dartford Crossing, which bears her name: The Queen Elizabeth II Bridge. She was fond of technology, famously using online video calls to meet people during the pandemic. She will be greatly missed by the UK manufacturing and engineering community, and everyone at MTI extends their heartfelt condolences to the Royal Family on their profound loss.

Getting down to business faster with NHP 5500

Mills CNC, the exclusive distributor of DN Solutions’ machine tools in the UK and Ireland, has introduced a next-generation, high-productivity horizontal machining centre. The new twin-pallet NHP 5500 represents a significant upgrade on its predecessor, and boasts faster acceleration/deceleration rates, improved tool change times, enhanced thermal compensation and faster B-axis table rotation.

DN Solutions’ NHP 5500 features acceleration/deceleration rates in X, Y and Z of 0.91G, 1.07G and 1.02 G respectively which, combined with its 60 m/min rapid rates, delivers faster processing speeds and a reduction in non-cutting times: all essential in ensuring higher productivity and process efficiency.

The focus on improving productivity is also evident with the machine’s faster tool change times. Equipped with a generous sized servo-driven ATC (from 40 up to 376 tools depending on the tool magazine selected), tool change times are 1.7 seconds (T-T-T) and 4. 7 seconds (C-T-C).

Notably, the NHP 5500 is equipped with a built-in 37 kW/10,000 rpm BT50 spindle with integrated smart thermal compensation sensor technology, This, combined with the machine’s spindle (oil-cooled) cooling system, reduces thermal displacement and ensures high part accuracy and repeatability, even during heavy-duty machining and long periods of operation.

The NHP 5500 has a rotary shuttle-type, twin-pallet configuration with a pallet-change time of 12 seconds. In addition to fast B-axis indexing (1.1 seconds for 90°, and 1.5 seconds for 180°), this capability enables customers to achieve higher productivity. The integration of a cone air blower that injects high pressure air into the location cones which connect the pallet to the table, removes chips from surfaces, resulting in accurate pallet positioning and improved process reliability.

Queen’s Award and relocation for CSS

Paignton-based CSS (Casting Support Systems) Group is having a year to remember with a visit to Buckingham Palace to collect a Queen’s Award for Enterprise and relocation to a purpose-built 60,000 sq ft factory. The relocation will see each of the three group company’s sharing the available space, with the toolmaking side of the business being the stand-out area for development.

With recent investment in new machining technology, the move involved relocating six machining centres from XYZ Machine Tools. CSS managing director James Head estimated that it would take three days per machine to complete the move. However, a concerted effort from XYZ’s machine movers and service engineers saw all six machines back in production, including laser calibration to within 6 µm/m, within seven days. Says Head: “It was an incredible effort by everyone concerned and, as a result of the prompt and efficient service, what we are now calling ‘XYZ alley’ was back machining parts in very quick time.”

Aiming to plug UK’s five-axis capacity shortage

A new subcontract manufacturing start-up is aiming to help plug the UK’s five-axis capacity shortage with a machine manufactured by one of his former employers. Jonathan Butler has set up Butler Precision Engineering, based near Dudley in the West Midlands, with the help of a Mazak VariAxis C-600 five-axis machining centre.

“It’s been a longstanding ambition to run my own precision machining company and there has never been a better time to make the plunge,” he says. “There’s a real gap in the market for five-axis capability due to limited machining capacity in the UK, which leads to too much work chasing too few available machining hours. My hope is that Butler Precision Engineering and the VariAxis can help plug the gap.”

After being operational for only a few weeks, Butler Engineering has already secured two contracts for turbine blade work and medical equipment.

“We’re getting a lot of interest, particularly from customers who want to use us as a development shop or for prototype work, which is perfect for the VariAxis,” he says.

Butler has 30 years’ experience in engineering, including time with Renault F1 as a machinist and programmer, as a machine shop manager for a fabrication company, and most recently as an engineering consultant for Quickgrind. During his time with Mazak, he learned all about the VariAxis i-600 machine, the forerunner to the C-600, as an application engineer.

He says: “It was my job to know the VariAxis like the back of my hand, so when I decided to take the plunge and set up my own business there was only going to be one machine that I wanted. You’ve got to know and trust the technology you’re working with.”

Earthmoving subcontractor opts for Quaser

When an ageing horizontal boring centre was on its last legs and the world was entering the pandemic, Rockingham Manufacturing found a suitable cure with a Quaser horizontal machining centre from the Engineering Technology Group (ETG).

Founded in 2004 out of the ashes of a previously failed business, Rockingham Manufacturing is a subcontract manufacturer that supports a diverse client base in the food machinery, diesel engine, earthmoving, factory spares and general manufacturing sectors. To cater for its diverse customer base, managing director Martin Scott believes it is imperative to have a horizontal borer or HMC to complement its four VMCs. So, when the Corby-based subcontractor found its horizontal boring machine unreliable and in need of replacing, the company turned to ETG and its Quaser HX504BPF twin-pallet HMC.

“The Quaser has a similar weight to its predecessor, but in a footprint that is 20% smaller. Despite the smaller footprint, the XYZ axis travel of 762 x 640 x 800 mm is considerably larger than the previous machine. Combining this larger work envelope with high-precision indexing of the B axis, we’ve reduced secondary operations as the Quaser can complete more jobs in one hit.”

He adds: “The Z and Y axes are much larger than the previous machine, and this allows us to machine bigger parts. However, it’s not just about large axis travels, but having the stability to machine larger components. For example, we wanted to U-drill some holes at 50 mm diameter in steel with the holes positioned beyond 500 mm high on the Z axis. The rigidity of the Quaser ensured this was no problem for us.”
