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.

60 start-ups from 12 nations at EMO

The EMO 2023 exhibition in Hanover, Germany (18-23 September) will once again feature a large start-up area on Stand E34 in Hall 9, presented jointly by EMO organiser the VDW (German Machine Tool Builders’ Association) and the VDMA Start-up Machine. “Start-ups bring a breath of fresh air to well-established industrial sectors because they often function as pioneers and trendsetters in their field of business,” says Stephanie Simon, who is responsible for the project at the VDW. “That’s why established exhibitors are often more than interested in talking to young companies.”

Software platform boosts machine tending

Universal Robots, the Danish manufacturer of collaborative robots (cobots), is releasing a new software platform specifically for machine-tending tasks. The name is PolyScope X and, through a customisable user interface, UR says it will add new levels of flexibility to high-mix, low-volume machine tending automation.With PolyScope X, machine shop operators can achieve changeover times of less than 10 minutes – far below what is possible today with any other software, reports the company.This capability will empower users to run more batches in a day and in a more strategic and flexible way.

PolyScope X arrives at a time when manufacturers all over the world are looking for increased flexibility to handle shifting and increasingly diverse orders. At the same time, the new software platform introduces a powerful reworked programming experience and toolset. This enables integrators and OEM partners to structure their program code in a way that makes each operation simpler to understand, maintain and troubleshoot.

“PolyScope X is a landmark development in machine-tending automation,” says Anders Billesø Beck, Universal Robot’s vice president for strategy andinnovation.“The simplicity of the user interface and the much faster changeover times will provide manufacturers with a whole new set of possibilities regarding how they automate their machine tending tasks.It will allow them to break some of the barriers that are holding them back today.”

PolyScope X for machine tending is initially available in Germany, the UK and Denmark.

Exotec manufactures milestone 5000th robot

Exotec, a global warehouse robotics provider, has manufactured its 5000th robot, just three months after the production of its 4000th model. This is the shortest time yet between manufacturing milestones, signifying a growing business momentum driven by the increasing demand for warehouse automation. The 5000th robot carries the name ‘Monu’ (short for ‘Monumental’).

Romain Moulin, CEO and co-founder at Exotec says: “We continue to see a strong demand for scalable and proven warehouse robotic solutions. We have a track record of serving the world’s largest brands, which places Exotec at the heart of the explosive growth of the global warehouse robotics market, which is expected to be worth $16bn by 2031.”

In 2022, Exotec signed its first major UK customer – multichannel fulfilment and returns expert iForce – and is already deploying two additional large customer projects in the UK.
Exotec has made significant strides in making warehouse jobs easier and less physically demanding. To this day, Exotec robots have saved warehouse workers from having to walk at least 16 million miles, which is the equivalent of going to the moon and back 33 times.

This year, Exotec is continuing its track record of innovation by investing in R&D. Since its inception, Exotec has doubled its R&D spend every year, and the company also commits 10% of all sales towards the development of new products.As of today, Exotec holds 26 granted patents with 68 patent applications still pending. The company filed almost 50% of all patents in the past six months.

Four new energy-saving ABBrobots in 22 variants

ABB Robotics is expanding its large robot range with four new models and 22 variants, offering more choice, increased coverage and greater performance. The next-generation models include the IRB 6710, IRB 6720, IRB 6730 and IRB 6740, suitable for payloads ranging from 150 to 310kg, with a reach from 2.5 to 3.2m.

“Sustainable production is a major priority of automotive manufacturers, with 78% of companies identifying it as important to their business and a further 77% identifying it as a priority for their customers,” says Marc Segura, president of ABB’s Robotics Division. “ABB’s four new robots offer 22 variants and energy savings of up to 20%, responding to our customers’ needs; offering greater choice and flexibility for more sustainable production. These new robots will help our customers build resilience across a range of industries including automotive, general manufacturing and foundries.”

ABB’s OmniCore controller and lighter robot design lead to energy savings of up to 20%. Featuring ABB’s TrueMove and QuickMove motion control technology, ABB says the robots can achieve class-leading repeatability with a minimum of 0.03mm deviation. These capabilities make the new series of robots suitable for complex tasks such as spot welding, laser welding, screwdriving and riveting.

“Our new robot range meets the needs of the rapidly growing electric vehicle (EV) industry,” says Joerg Reger, managing director of ABB Robotics Automotive Business Line.“As manufacturers ramp up the production of EVs and batteries, they can choose from a wide range of ABB robots to ensure they have the right variant to handle batteries of different sizes, from individual cells and modules to complete packages.”
