UNITED GRINDING Presents a World Premiere at EMO 2021
The UNITED GRINDING Group, a manufacturer of precision machines for grinding, eroding, lasering, measuring, and combination machining, is presenting a revolutionary innovation at EMO 2021 in Milan: UNITED GRINDING C.O.R.E. Each of the Group’s brands – MÄGERLE, BLOHM, JUNG, STUDER, SCHAUDT, MIKROSA, WALTER, EWAG and IRPD – will be on hand to see the innovation presented to the public on the first day of the trade fair (October 4, 2021 at noon local time).
No details about C.O.R.E. are being divulged ahead of the official market launch. Stephan Nell, CEO of the UNITED GRINDING Group, is only willing to reveal this much: “We have invested unwaveringly in research and development both before and during the coronavirus pandemic, to secure the future – not just for us, but above all for our customers. And when we talk about the future, it is inseparably linked to digitalization today and with an increasing work simplification in production.” In this connection, C.O.R.E. is intended to put the focus back on people – and in a truly revolutionary way. The brand name says it all: C.O.R.E. – Customer Oriented REvolution.
Experts from each of the Group’s three technology areas – surface and profile grinding, cylindrical grinding, and tool machining – worked within a joint team on this groundbreaking development. “This project reflects our bundled development expertise,” explains Christoph Plüss, CTO of the UNITED GRINDING Group. “Through C.O.R.E., we are laying the foundations for a new generation of machine tools to pave the way into the digital age.” The result is a world-first that encompasses all of the Group’s brands and machine types.

Milling Instead Of Grinding With The Hand Angle Miller
The wide range of milling discs, special techniques when milling by hand, as well as the use with hand angle millers and in (partially) automated processes. The milling discs are available in the three different kinds “milling disc”, “double sided milling disc” and “doubleworker”, which aim different areas of application.
For all of those the following applies:
The surfaces processed with the discs are metallic bright, and therefore prevent cavities while welding. While working, the discs produce neither (unhealthy) dust nor heat, and thus no structural changes that come with heat. The amount of material removed and the fineness of the result depend on the toothing. The fewer teeth, the coarser the chips and the greater the amount of material removed. The more teeth a disc has, the finer the chips and the smoother the surface, but less material is removed. The specific toothing depends on the material to be machined and the disc size.
The discs can be used for the following tasks:
- The milling disc gets used for bevelling, deburr and flatten as well as working out weld roots.
- The double sided milling disc (DMD) is used to open weld roots, according to the literal translation of the German original description, that would be “weld root opener”. Due to the teeth geometry, it is not made for the tasks performed by a single sided milling disc.
- The Doubleworker (DW) combines the scope of single and double sided milling discs, without the need to frequently change the tools. The teeth geometry of the double sided milling disc had been adjusted to resolve the problem of chips getting stuck in the chip chamber.
Maija-Frästechnik GmbH, founded in 2012, develops, produces and sells high-quality milling tools made of hard metal. The company owns the patent for milling discs, which was registered in 2000 by the later company founder.

Laser Process Measuring Technology for Precision Machining
Integrating laser measuring technology expands the possible applications of process measuring technology in grinding machines, supporting the user in his efforts to increase efficiency in precision machining. Article by STUDER.
Finishing processes on grinding machines often demand exacting tolerances in relation to dimension, form and position accuracies, as well as highly accurate surface qualities. Often, companies have empirical values available to fulfil these requirements.
However, with small lot sizes in particular, process evaluation on the machine is desirable, as intermediate measurement on external measuring machines and the resulting corrections prolong the processing time for part machining. These control measures would significantly increase process reliability and productivity. Solutions that can be flexibly used for a wide variety of workpieces are ideal and preferable.
Measuring Technology in Grinding Processes
Production engineers have diverse measuring functions available for process evaluation, which are based on different principles of production measuring technology. The measurement of process forces such as grinding forces (Ft, Fn) or comparative grinding spindle currents, for example, provide an index for achieving the service life of tools or, equally important, they enable the determination of fluctuating allowances, which can influence process stability and compliance with required tolerances.
In addition, tool costs can be reduced, as excessive dressing is prevented. Familiar acoustic touch sensors assist so-called contact detection in the grinding process to reduce grinding time, or monitor the true-to-profile dressing process with its envelope curve functions. Tactile measuring systems such as measurement and control systems for diameters or workpiece lengths, pneumatic systems or microsensors for longitudinal expansions of spindle systems also support increased process reliability.
Other measuring functions can also be described here, such as the use of camera or laser systems for process monitoring. Laser measuring technology in particular opens up interesting fields of application.
Integrating Laser Measuring Technology into Grinding Machines
STUDER can draw on more than 10 years of experience in the use of machine-integrated laser measuring technology, which have been evaluated for trials in the measurement of grinding wheels or workpieces. Such fundamental studies have a tradition at STUDER, to ensure the company is prepared for future trends in production technology. This knowledge and experience has been used to respond to the current requirements. The systems used in other industries for tool monitoring have been further developed by STUDER, on the basis of the latest laser measuring technology, only recently available, for measuring workpieces on grinding machines.

A Remedy To Uncertain Times
Medical manufacturing company Straits Orthopaedic delivers on diverse medical applications with their flexible ANCA CNC grinding machines. Article by Duncan Thompson, ANCA.
If manufacturers have learned anything over the recent months, it is that you can take nothing for granted. Circumstances can change quickly and how you are set up to respond can be the difference between your business flourishing or folding. Recognising this, Straits Orthopaedic has been investing in ANCA machines as part of their strategy to be a flexible manufacturer in the medical tooling and component market.
The events of COVID-19 this year are perhaps the most extreme example of rapid market change and resulting uncertainty. But, even after more normal circumstances return, manufacturers need to be constantly vigilant, watching and responding to changes in the market that provide new opportunities or necessitate a pivot in their business.
ANCA CNC grinding machines have long been recognised in the industry for their flexibility. It is this kind of flexibility that allows ANCA users to produce parts for diverse applications, so they are not limited to just one customer or one application. Powerful software allows users to create programs for a broad range of cutting tools and components. While modular machine design means features can be easily configured to suit the varying needs of different applications.
The medical industry offers exceptional and diverse opportunities for manufacturers, with ANCA grinding machines supporting international markets in the production of complex bone rasps, long rotary reamers and tiny dental drills and burrs, just to name a few.
Straits Orthopaedics, based out of Malaysia, is a case-in-point of a company taking advantage of ANCA’s diverse capabilities. Already well established for contract manufacture of medical components, Straits Orthopaedics’ first tool grinder was an ANCA FX5.
Senior Process Development Engineer Vidyadhiraj Vidyadharan comments, “Custom made tools have become a significant part of our growth in the medical tool market. We need the ability to make special tools to varying customer requirements and to be able to do it quickly. ANCA’s FX5 with its flexible tool programming software has certainly allowed us to meet this need. Demand for our diverse range of medical drills, reamers and planers easily justified our second FX5.”
