Flexible and at the same time highly productive solutions for grinding for electromobility and similar applications – this is what the EMAG Group demonstrated at the GrindingHub exhibition earlier this year. The company put together an interesting programme for the new trade fair for grinding technology. In addition to exhibits such as universal cylindrical grinding machines from EMAG Weiss and the VLC 350 GT combination machining machine, the company gave an insight into developments in the field of Industry 4.0 and IoT, in which a lot has happened in recent years – including in grinding technology.

In order to make it as easy as possible for EMAG customers to enter the world of data-optimised production, machines can now be delivered IoT-ready. This makes it possible to integrate the machines directly and without major effort into existing IoT networks.

Emag Weiss showed two machines at GrindingHub: a W 11 CNC and a W 11 EVO. The W 11 CNC is a grinding machine equipped with a modern, fast, grinding-oriented control, while the W 11 EVO is a further development of the well-known K11 series. The latter is a new, contemporary version of the conventional grinding machine with many extras that make production life easier: hydraulic-free, axle drives with servomotor and ball screw, modern HMI with touchscreen, automatic parallel dressing and free-driving.

Both machines offer high precision in external round machining with a grinding length of up to 2000 mm and a maximum grinding diameter of 360 mm.

EMAG also presented a VLC 350 GT for the first time at GrindingHub. The GT abbreviation stands for ‘Grinding’ and ‘Turning’. They indicate the strength of this machine: the combination of grinding and turning (plus other processes) with the proven EMAG pick-up automation enables countless manufacturing solutions.

Evapo-Rust from CRC Industries is a water-based rust remover that is biodegradable and non-toxic for the user and the environment. Its award-winning formula eliminates rust without having to scrub or sand parts. Furthermore, it is economical as the product is suitable for reuse several times. CRC says that Evapo-Rust can restore metal parts and tools rapidly and efficiently in all industries: automotive, construction, marine and general metalworking.

To use Evapo-Rust, which is REACH compliant, simply immerse the part in a bath of the ready-to-use solution. The rust then detaches from the metal surface and remains suspended in the liquid. Notably, the active ingredient in the formula binds exclusively to iron, removing only the rust from steel, iron, cast iron and chrome. It thus preserves the non-oxidised metal and is harmless to other metals. Compared with conventional acidic or basic strippers, CRC Evapo-Rust is non-toxic, non-caustic and non-corrosive, and does not affect plastic, PVC, Viton and non-oxidised paint on treated parts.

According to CRC, Evapo-Rust removes the thickest layers of rust down to bare metal, leaving no residual layer and requiring no sanding or blasting. The treatment is fast: it is possible to remove a light layer of rust in only 15 to 30 minutes; a medium layer in 6 hours; and a thick layer in 12 to 24 hours. It works at room temperature, although it is possible to accelerate results by heating to 50°C.

It takes 5 litres of Evapo-Rust to remove 0.3 kg of pure dry rust. Moreover, preliminary cleaning is only necessary in the case of very dirty and greasy parts.

Following a very flourishing experience at the MACH show in Birmingham earlier this year, abrasives specialist Tyrolit followed it up by exhibiting alongside Brit Plant at Rail Live 2022 in Warwickshire in June. Tyrolit’s team provided extensive insight into its dedicated rail technology expertise. Working with demanding requirements for short grinding times, combined with the need for long service life, Tyrolit’s rail machining solutions are suitable for the most diverse needs often under difficult application conditions.

Last month, at another week-long show, Tyrolit showcased its precision aerospace solutions at the Farnborough Air Show. The company has more than a century’s worth of abrasives experience in aerospace and MRO, helping customers to identify the optimal solution for any application. Additionally, Tyrolit demonstrated ToolScope – an Industry 4.0 modular assistance system that allows users to unlock the full potential of their manufacturing processes through the digitalisation of grinding technology.

On 12-13 October, Tyrolit will be returning to The Speedy Expo, one of the UK’s leading tool, equipment and plant hire events in the north of England.

Says sales director Pete Dufty: “As we all return to normality following the pandemic, it’s a powerful time for our business to interact with customers and demonstrate the wealth of our industry expertise. We hope that our presence at these shows is proving hugely beneficial for those visiting.”

As a manufacturer of grinding and dressing tools, these events provide the opportunity to demonstrate that Tyrolit is a proven partner in multiple industries.

Studer’s new SmartJet concept supplies a precisely controlled flow of coolant to the grinding wheel, saving costs and increasing sustainability in production.

On many grinding machines it is the operator’s task to manually control the cooling of the grinding process. He or she must position the nozzles correctly and operate the ball valve by hand. A pump then transports the cooling lubricant to the grinding process location. Often, this uses more coolant than necessary or the nozzles lack optimal positioning, which is bad for efficiency and the environment. Studer says it is breaking new ground with its patented SmartJet concept.

From now on, cooling will be the responsibility of the machine control unit. The central components are a frequency-controlled pump and a dynamic pressure measuring unit. This concept makes it possible to set the volume flow precisely to suit the process, whether for roughing, fine grinding or finishing. The coolant flows through a distributor piece and flow-optimised, adjustable nozzles to the grinding wheel.

“Our new concept guarantees precise and reproducible cooling,” emphasises Martin Habegger, project manager. “We create a consistent jet of coolant with a high exit velocity in the range of 12 to 20 m/s, which effortlessly overcomes the air movement caused by the wheel.”

As a result, process reliability improves and less coolant is required to produce equivalent grinding outcomes.

In conclusion, SmartJet not only accelerates set-up time for users, it also enables them to grind significantly more efficiently and sustainably.

“It reduces water consumption by 40% and energy requirements by up to 50%,” states Habegger, before adding: “SmartJet makes a significant contribution to making machining more eco-friendly.”

The new Vollmer CSF860 side grinding machine and CS860 face and top grinding machine both made their worldwide exhibition premiere at the GrindingHub exhibition in May, superseding the company’s CHD 270 and CHF 270 saw blade processing machines.

“The base, the housing and many other elements are completely different to before, but components that have proven their stability and accuracy over many years remain,” explains product manager Thomas Wenger. “We’ve designed both new machines with the same kinematics, housing, structure and polymer concrete base, so we can have a modular foundation. This makes the machine easier for the operator to handle as there is greater synergy between the CS and CSF machines, creating uniformity with regard to loading, setting-up, ergonomics and programming.”

He adds: “This uniformity of technology was our target, adopting the same CNC, operating philosophy and the latest drive technology. In the past, we used some servomotors with standard synchronous motors. Now, all motors, grinding spindles and axes are servo-driven. We have seven motors on the CSF side grinder and eight on the CS face and top grinder. This includes linear CNC axes plus three CNC grinding spindles on the face/topper and two CNC grinding spindles on the side grinder. The servo-driven grinding spindles provide a higher quality saw blade and we can now conduct different in-feed and cutting speed rates on each tooth. This improves the surface quality of the cutting edge and brings more flexibility into the grinding process.”

With any new concept, the team at Vollmer aims to achieve four key delivery parameters for customers: increased flexibility, productivity, reliability and quality.

“We met the goals by creating more stable processes in the new machines to provide better grinding results at the cutting edge,” says Wenger.
