Precision in a double pack: The \u00b5m-precise production partnership<\/strong><\/p>

Precision in manufacturing doesn\u2019t happen by chance: the \u00b5m only works when all components fit perfectly together! For machining centres, this includes zero-point clamping systems and the right vices, such as those from LANG Technik GmbH in Holzmaden.\u00a0<\/p>

The company relies on PEACOCK milling cutters from ZECHA Hartmetall-Werkzeugfabrikation GmbH to ensure that nothing is left to chance in their production.<\/p>

Their role is rarely celebrated, even though it makes a significant contribution to efficient machining processes in the background. Workpiece clamping technology is responsible for the secure and precise fixing of the workpiece and thus for the necessary stability during the machining process. LANG Technik is a global leader in clamping and automation technology. As a manufacturer of high quality innovative products for the machining industry, LANG Technik sees itself as a partner for all those who are looking for flexible and reliable clamping devices for their milling operations: from one-man shows to global corporations, as well as from a broad spectrum of industries such as mechanical engineering, medical tech, aerospace, automotive, motorsport and more.<\/p>

LANG Technik \u2013 fully operational<\/strong><\/p>

There is a long list of challenges in modern machining: production processes need to be simplified and made more efficient and manufacturing capacities need to be fully exploited. The focus is also on reducing set-up times and increasing machine utilisation \u2013 the ideal arena for LANG Technik\u2019s solutions. Manuel Daiber, Production Manager at LANG Technik, knows what is important here: \u201cForm fit connections are the key to maximum precision. That\u2019s why we at LANG Technik developed our patented stamping technology back then. A separate embossing station is used to create a truncated pyramid shaped blank in just a few seconds which is then reproduced in the clamping system \u2013 with huge advantages for the actual milling process.<\/p>

The highest holding forces, maximum process reliability and exact repeat accuracy are benefits which speak for themselves. Manuel Daiber: \u201cWhat makes us different is the clamping to just 3mm from the contact surface to the top edge of the vice. This minimises stress on the workpiece and the user benefits from the sustainable use of the material used.\u201d<\/p>

LANG Technik has 150 employees worldwide, with around 100 in Holzmaden, where the company primarily produces its serial products from zero-point and workpiece clamping technology to automation solutions developed in-house \u2013 everything \u201cMade in Germany\u201d.<\/p>

The challenge: 55-60 HRC steels\u00a0 \u00a0\u00a0<\/strong><\/p>

When Manuel Daiber switched from automation development to vice production in 2020, he was confronted with very high tool consumption. \u201cThe milling cutters really didn\u2019t cost the earth, but as we wanted to produce into the weekend, we needed performance and reliability!\u201d So he started looking for tolls that would allow faster processes in general and simultaneously be able work unmanned from Friday afternoon to Monday morning. Nothing to be sniffed at when mainly hardened steels of 55-60 HRC have to be machined.<\/p>

\u201cEach component already has a certain production history before it goes into hard machining. If I then produce rejects during the night shift or at the weekend because of a poor or underperforming tool, it costs money. Thanks to ZECHA\u2019S PEACOCK milling cutters, however, I no longer have to worry about this,\u201d reveals Manuel Daiber. A modern CNC machine park, high-end measuring and testing technologies, carefully selected carbides from leading manufacturers and uniform carbide qualities ensure consistent tool quality at ZECHA \u2013 a key factor in autonomous series production.<\/p>

PEACOCK cutters set the pace\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\u00a0<\/strong><\/p>

The trick was to achieve the highest quality unmanned, reliably and overnight. And that was for a number of demanding machining tasks on the vices. \u201cOne ZECHA cutter replaces three other cutters. The amazing thing is I\u2019m four times as fast. And what\u2019s even better is that a single PEACOCK cutter can machine even more components than the three previous cutters combined!\u201d exclaims Manuel Daiber enthusiastically.
ZECHA\u2019s cutting data calculator plays an important role in such impressive results. \u201cIt simply gives you values that you can actually run with! As it allows me to run significantly higher feed rates, I\u2019m much faster and I can make four or five times as many parts with consistently good quality \u2013 despite the high speed and vast quantities!\u201d In addition, the tools don\u2019t need to be changed prematurely: with cheap cutters, you have to worry about their next performance, with ZECHA\u2019s cutters you can keep on using them without hesitation.<\/p>

At the same time, idle times are reduced because set-up times are significantly lower.<\/p>

Well-positioned for hard machining\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0<\/strong><\/p>

Klaus Bruder, Technical Support at ZECHA Hartmetall-Werkzeugfabrikation GmbH says \u201cTool concentricity is also an important factor in hard machining. After all, we work with multi-edged tools, so even a hundredth of a concentricity error is theoretically enough to prevent all cutting edges from being used. While this may no be a problem immediately, it certainly will be once the cutting edges wear down, causing problems with both the surface and the tool life. Thankfully, our PEACOCK cutters have form and concentricity accuracies of 0.005mm and 0.003mm respectively.<\/p>

PEACOCK cutters are designed as special flat peripheral cutters with a high-end WAD coating. For additional cutting edge protection, they have a finely ground protective radius of max. 0.05mm or have defined ground corner radii, depending on the version. This special cutter design scores very highly in terms of performance and wear, therefore offering high machining efficiency for a wide range of materials, alloy components and material hardnesses up to 67 HRC.<\/p>

Three-point plan for process optimisation\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0<\/strong><\/p>

Manuel Daiber remembers the time when production hadn\u2019t yet reached its optimum level: \u201cTo be honest, the initial spark really came with the ZECHA moulds because the feed rates we now have would have been impossible before!\u201d But that was not all he achieved together with his colleagues and the expert advice from ZECHA. Manuel Daiber: \u201cPersonally, I need any improvement to deliver on three key metrics \u2013 more speed, lower costs and easier operation. I\u2019m only satisfied when all three of these points are met and everyone benefits. And by using PEACOCK cutters from ZECHA, we have achieved exactly that and actually gained room for further optimisation!\u201d<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
