Metalite moulds automated future

Injection mould tool specialist, Swindon-based Metalite Engineering, has recently added to its plant list with the arrival of a Quaser five-axis UX500C machining centre and a 10-pallet Erowa Robot Easy 250 pallet loading system. Supplied and integrated by the Engineering Technology Group (ETG), the new investment is adding significant capacity to Metalite with its unmanned machining capability.

The UX500 is primarily for medical sector work, although Metalite is also highly regarded for its ability to serve the aerospace, automotive, Formula One, food packaging and horticultural industries. In total, the machine has 60 tools and a 15,000 Maxia spindle with a face and taper dual-contact system. Additionally, the UX500C has rigid knuckle-type axis rotation to provide full machining access around the component. Metalite needs this flexibility and precision as it is making parts that extend from small medical components with 5 µm tolerances, up to large tool steel die parts. For this reason there is a crane on the automation system to load larger billets.

ETG’s Steve Brown says: “The partnership between Quaser and Erowa goes a lot deeper than what is here in the UK. Both companies have a technical partnership and that is rolled through to us at ETG. So, we are the distributor for Quaser machines, and we have great support from REM Systems that supply the Erowa system. When we enter into a package together, we can tailor the solution to meet the needs of the customer.”

The success of this installation has already seen Metalite order a second system that will be applied to a three-axis vertical machining centre, where the robot loading system will incorporate four pallets.

More awareness of airborne particulates

In a survey carried out by the Safety and Health Engineering Partnership (SHEP), 84% of respondents stated that the pandemic has made them more aware of how virus, bacteria and other particles transmit through the air, with 70% advising that Covid-19 has made them more mindful of the dangers of airborne particles.

“What is worrying is the fact that 27% of responses said that their employer does not provide training on how to use control measures, while 21% admitted that their local exhaust ventilation [LEV] systems are tested by a competent person less than once every 14 months,” says SHEP chairman Chris Buxton, CEO of the British Fluid Power Association (BFPA). “Providing controls is a great start, but if operatives do not understand how to use them, they may have little impact. LEV is widely regarded as the most effective control for airborne particles and COSHH regulations require a minimum testing frequency of 14 months, which means that many UK manufacturers are potentially still not adhering to this requirement.”

Bearing giants opt for SIC Marking solutions

To prevent counterfeiting, SIC Marking says that an increasing number of the world’s largest bearing manufacturers are adopting its traceability solutions. For instance, the company recently supplied a solution to a major Swedish ball bearing manufacturer that wanted to mark an alphanumeric and Data Matrix code on steel bearings with diameters ranging from 150 to 600 mm. SIC Marking’s customised station is equipped with an IPG 50W laser for marking on the bearing face, and an IPG 3D laser – automatically controlled in two axes – that is capable of marking on the part radius. SIC also integrated a proof-reading system.

MRT ‘turns the tables’ on Brother machines

Established in 1947, MRT Castings specialises in the manufacture of high-quality aluminium die castings. In addition to regularly investing in the most up-to-date casting technologies, the progressive family business has introduced a range of complementary end-to-end services over the past 70 years. Along with state-of-the-art high-pressure and gravity die casting, the Andover-based company now provides tool making, surface finishing, mechanical assembly and, not least, a comprehensive CNC machining provision.

The mainstay of MRT Castings’ impressive machining facility is its collection of Brother CNC vertical machining centres supplied by Whitehouse Machine Tools. MRT’s policy of standardising on machines from a single supplier provides enhanced flexibility, as both operators and products are interchangeable between machines.

Additional benefits include the use of standardised fixtures, tooling and CNC rotary tables.
Having previously used two well-known brands of CNC rotary tables, following advice from Whitehouse Machine Tools, the company’s most recently installed Brother VMCs feature PL Lehmann CNC rotary tables.

MRT Castings’ managing director Phil Rawnson says: “We are able to support our customers from initial ideas, through product development and design for manufacture stages, to full production and logistics. Our extensive in-house CNC machining facilities are at the very core of our operations. To help ensure short lead times and the manufacture of premium quality products we use a range of Brother machine tools, the fastest machining centres available.

“Such is the quality and cost-effective nature of our CNC provision, in addition to machining die castings that are produced in our own foundry, we also machine components cast by other companies,” continues Rawnson. “As we usually perform small-to-medium production runs on a diverse range of products, we need each of our machine tools to deliver the best possible levels of flexibility, while also striving to maximise machine utilisation times and minimise set-up times. Over several years, our use of rotary tables has made important contributions in these areas.”

As many of the components manufactured at MRT Castings are relatively complex, without the use of rotary tables the company would need to perform two or three different machining operations, rather than producing parts in one hit. The ability to finish components in a single cycle means that MRT does not face the issues related to the accurate relocation of workpieces for subsequent machining operations.

“Over the past 12 months we’ve been involved in the casting and machining of critical parts that were urgently needed for medical ventilators,” explains Rawnson. “To help keep pace with this challenging production schedule we brought the planned purchase of six Brother vertical machining centres forward, bringing our current Brother VMC count up to 25 machines. To provide highly efficient four-axis capabilities, each of our latest six Brother VMCs feature rotary tables from PL Lehmann, which has provided us with a range of advantages.

He adds: “Despite our Lehmann CNC rotary tables being extremely robust and able to perform all the tasks we require, when compared with our previous rotary tables they are relatively small. Their reduced footprints mean that, when mounted inside our Brother VMCs, they take-up minimal area. In addition to releasing machine bed space for other work holding, the reduced size of Lehmann CNC rotary tables means that, when they are not required, they can often remain inside our VMCs while other machining operations take place. Additionally, the reduced height of Lehmann CNC rotary tables helps to increase the available working volume of our machines.

“As well as benefiting from the quality of Lehmann’s products, we received excellent installation and interface help from Whitehouse Machine Tools and PL Lehmann’s UK service agent. The machining flexibility, precision and speed delivered by our Lehmann rotary tables is now proving invaluable to MRT Castings.”

PL Lehmann has been involved in the design and manufacture of high-quality rotary tables for over four decades. The in-depth expertise gained throughout this time is reflected in the quality of the company’s products. To help reduce parts and enable the availability of Swiss quality at a cost-effective price, Lehmann rotary tables are based on a novel modular design system. This highly efficient arrangement enables the availability of a wide range of CNC rotary table options to meet customer needs.

Four sizes of Lehmann CNC rotary tables are available – 507, 510, 520 and 530 mm – with centre heights from 110 to 240 mm. Due to the company’s modular design approach, from these size options it is possible to offer more than 170 different rotary table variants. Models are available from basic single-spindle 4th axis units, to four-spindle tilting rotary tables with 4th and 5th axis capabilities. Now, rather than compromise and obtain a rotary table that represents a close match to a machining requirement, Lehmann customers are able to take delivery of a high-quality CNC rotary table that corresponds exactly to their specific needs.

In addition, the company’s modular design system means that the purchase of a well-engineered Lehmann CNC rotary table represents a safe, future-proof investment. For example, if a customer’s manufacturing requirements change, instead of investing in a new rotary table, the existing Lehmann CNC unit can be easily modified and adapted to changes in use.

Lehmann’s standardised spindle arrangement allows the use of an extremely wide range of workpiece clamping systems. As a result, in addition to standard work holding being set-up for an initial workpiece range, the system can quickly convert to accommodate other workpieces.

PL Lehmann says that its heavy-duty CNC rotary tables have earned a global reputation for performance, quality and longevity. Further aiding efficient, precision machining, the company’s robust products benefit from high clamping torque, load weight capabilities and accuracy specifications.
