Hybrid mill/grind machine cuts cycle times

Manufacturers can now achieve faster processing times thanks to the hybrid milling and grinding capabilities available on the new Mikron MILL S/X (U) series from GF Machining Solutions. The new series combines milling and jig grinding in a compact footprint.

According to GFMS, these three- and five-axis machines deliver accuracy, precision, speed and best-in-class ergonomics. The various models can operate as stand-alone machines or, to improve productivity, can be integrated with automation systems to create flexible manufacturing cells.

Featuring Automated Machine Calibration (AMC) from GFMS and an advanced cooling system that cools the machine’s structure and spindle, changes in ambient temperatures or heat generated within the work environment during machining operations do not affect the machine’s ability to deliver high accuracy, even during long machining runs or extended periods of operation.

The AMC package allows operators to recalibrate the machine and recover its original precision, at the press of a button.

In MILL S and X machines, GFMS accommodates the grinding set-up within the standard footprint, while the laser measuring system and dressing spindle (boasting an increased spindle speed from 3000 to 20,000 rpm) are located close to the working area to ensure quick and fast grinding. In addition, the dressing spindle sits at a slight inclination in order to dress any type of grinding tool.

GFMS can equip the machine with an additional AE sensor to track grinding operations. Additional AE sensors are located on the machine table, allowing operators to adapt the process using the automatic tool detection cycle. This cycle, developed by GF Machining Solutions, avoids air grinding by detecting exactly when the grinding tool touches the part – thereby optimising the process.

Tyrolit picks up the pace with Cerabond X

Stock removal taking longer than expected and product wearing out too quickly? Tyrolit says that its Cerabond X brings a new dynamic to the process by maximising stock removal through enhanced abrasiveness, reducing working times and prolonging product lifetime in combination with a uniform finish.

Widely used in the market, ceramic grain is one of the most common forms of abrasives, known for being sharp, tough and strong. However, despite the advantages that ceramic abrasive grains have regarding stock removal, the best grain in the world can only be utilised for a limited time should it not be combined with a quality vulcanised backing and bond structure.

Tyrolit’s new self-sharpening ceramic grain, combined with a bespoke bonding system, is said to enable optimal bonding of the ceramic grain. New to the market, the Cerabond X product range not only includes fibre discs, but also a full range of metal removal products, including cut-off wheels, rough grinding wheels, flap discs and belts, which are suitable for all steel and stainless steel stock removal.

The structure of the ceramic grain in the new Cerabond X products not only provides extremely fast stock removal, but also shorter cutting time, reports Tyrolit. With the added benefit of flap discs featuring a trimmable core, the products deliver 30% higher stock removal rates. Furthermore, the entire disc can be utilised, maximising lifetime through the need of fewer discs.

Due to the durability of ceramic grain, combined with the bonding structure, Tyrolit says that the products perform better than others when used at high pressure, making the new Cerabond X system suitable for heavy-duty applications.

Cost-efficient finishing of balancing weights

Today, centrifuges are the most commonly used systems for cleaning and recycling the process water required in mass finishing operations. A case in point is Wegmann Automotive, a specialist supplier of balancing weights, which is today utilising a fully automatic Rösler Z1000 centrifuge.

As a pilot customer, Wegmann expanded the software for its centrifuge with the ‘advanced version’ of the digital process water management system from Rösler Smart Solutions.

Wegmann makes its balancing weights as stampings from steel and galvanised steel, as well as die-castings from zinc or zinc alloys. Eugen Weizel, department manager for mass finishing and coating, says: “After the stamping or die-casting process, the weights undergo a part-on-part mass finishing operation in a rotary vibrator. The goal is to remove the residual oil left over from the stamping process and the water-based mould release agent that remains from the die-casting operation. At the same time, the compound provides corrosion protection for the steel parts, while the zinc die-castings require a certain surface tension for the subsequent coating step. The surface tension is carefully monitored and controlled.”

Since the process water is recycled, the process water cleaning operation – with a fully automatic Z1000 centrifuge from Rösler – and control of the compound concentration are key factors that determine the quality of the balancing weights.

Says Wegmann’s Manuel Salomon: “When the mass finishing machine and the centrifuge were commissioned, we quickly recognised that there is a close correlation between the process water quality and the quality of our products. Therefore, we carefully measured the compound concentration once per week and recorded the measured results. This allowed us to define the compound concentration for our finishing process and correct it as needed.”

CO2 footprint calculator adds up for PPS

A new carbon footprint calculator for metal polishing is the result of an exciting tie-up between industry and academia. Professional Polishing Services (PPS), which has created three new jobs in the past 12 months, has tapped into funding and advice from the University of Birmingham’s ATETA programme to develop a digital process that will help it identify thousands of pounds of savings on energy costs.

The project involved mapping out manufacturing flows and installing high-end data logging sensors in key places to monitor the real-time power consumption of industrial equipment.
Notably, the equation takes account of several variables, including type of material and speed of job, to provide robust calculations that work out carbon footprint and identify potential savings.

The West Bromwich-based company is not looking to keep this IP to itself. Instead, PPS is planning to roll-out the calculator to the rest of the finishing sector in a bid to help industry move towards net zero.

Kirsty Davies-Chinnock, managing director of PPS, says: “Our bespoke stainless steel and non-ferrous polishing services are energy-intensive, so it made perfect sense to look at how we could monitor costs, especially with prices going through the roof. We now have a carbon calculator that can instantly work out the footprint of each job we put on our lines, which is fantastic information to have. It gives our production team the opportunity to look at how we save energy, making us more competitive in the process. The next step will be to roll this out to the rest of our sector and we’re already talking to the university and our competitors to see exactly how we do this.”

T&G at the ‘core’ of precision grinding

Given industry’s growing use of the IoT and the emergence of smart factories, potential machine tool customers are increasingly looking to purchase cutting-edge manufacturing aids with ‘smart’ controls and enhanced connectivity capabilities.

One such progressive company is Surrey-based T&G Engineering, which recently installed the UK’s first Studer S31 universal cylindrical grinding machine to feature the new United Grinding C.O.R.E. (Customer-Oriented REvolution) operating system.

T&G’s engineering director Tong Smyth says: “The Studer S31 universal cylindrical grinding machine was ordered because of the ever increasing amount of high-precision cylindrical grinding we need to perform. As we have done in the past, before our latest Studer purchase we liaised closely with Peter Harding, the managing director of Advanced Grinding Supplies, the exclusive Studer agent in the south of England and Wales. This co-operation ensured that we specified our new Studer machine to suit our exacting requirements.”

He adds: “In keeping with our policy of ordering machine tools featuring technology that will aid efficiency, our new Studer grinder uses United Grinding’s latest C.O.R.E. operating system. C.O.R.E. is now incorporated into our in-house digital communication and production systems, further improving our programming and grinding efficiency levels.”

Thanks to the uniform C.O.R.E. software architecture, exchanging data between United Grinding machines is now effortless. The integrated system’s universal machine technology interface (umati) can also communicate with third-party systems, while also providing access to United Grinding’s Digital Solutions products directly on the machine without requiring the installation of additional hardware.

The C.O.R.E. panel has a logical design and uses self-explanatory icons, allowing the operator to navigate through the machine’s menu and process steps intuitively.
