Since 2019, Stephan Mayer has been responsible as President China. Stephan Mayer is responsible for all TRUMPF activities in China and manages the two locations in Taicang/Jiangsu and Jinfangyuan CNC Machine Co., Ltd. (JFY) in Yangzhou.
Stephan Mayer studied mechanical engineering at the University of Karlsruhe from 2000 – 2004, where he also earned his doctorate in 2007 – 2009. Mayer, a native of Schramberg, worked in consulting at McKinsey & Company Inc. in Stuttgart from 2004 until he joined TRUMPF.
Heinz-Jürgen Prokop started as Head of the Design Department at TRUMPF Lasertechnik GmbH in Ditzingen, Germany, in 1988 and was Vice President, Head of Development/Design and production at IHI-TRUMPF-Technologies in Yokohama, Japan, until 1992. After holding various external positions as Managing Director at Thyssen/Krupp in Essen, Fritz Studer AG in Steffisburg, Switzerland, and Frigoblock in Essen, he returned to Ditzingen in 2012 as Managing Director of Development and Purchasing at TRUMPF Werkzeugmaschinen GmbH + Co. KG. Since July 1, 2017, Heinz-Jürgen Prokop has been a member of the Group Executive Board as CEO MT.

Changing Times In The Metal Cutting Industry
Today, workpieces need to be machined using multiple tools and fast tool change systems are becoming the norm. Article by heimatec.
Today, workpieces generally need to be machined using multiple tools, which in turn means that tool changes are required during the machining process. In order to keep the changeover and adjustment times as short as possible, the use of fast tool change systems has become the norm. Here, heimatec, manufacturer of high-precision static and driven precision tools for lathes and machining centers, introduces its wide range of solutions for fast tool changing.
Flexible System
Efficient manufacture is made significantly easier in two aspects. If machine downtimes can be reduced, the productive time increases automatically. By using flexible universal tools, the tool inventory can also be reduced, resulting in cost savings.
heimatec developed the flexible heimatec.u-tec tool change system for this purpose, which allows machining companies to utilise different adapters for a wide variety of machining tasks. The driven heimatec.u-tec tools are designed with a collect chuck mount according to DIN 6499, allowing the user to use the driven tools without additional tool adapters. A special feature of the heimatec u-tec change system is the short mounting length which ensures exceptionally stable clamping of the cutting tool with low cantilever forces, leading to excellent machining results and a long service life of the cutters.
Reducing Machine Downtimes
The company has developed the easy-quick HT series specially for fast changes in the area of driven and static tools. This means different tool change inserts with market-standard tool mounts can be preset outside the tool machine and when required, can be simply, safely and quickly installed by the machine operator with one hand. With this series, machine downtimes are reduced significantly. In addition, the overall tooling costs are reduced thanks to the multiple and flexible use of the easy-quick base tools.

Manufacturing Quality Starts with the Motor
Accuracy and surface quality are the goals of superior production processes. This is why machining companies invest a great deal of time and expense in tools, machine tools, controls with special functions and options, measuring technology, and, of course, employee skills. Unfortunately, axis motors still receive very little attention in this arrangement, despite being a decisive factor in production quality. Article by Heidenhain.
Electric motors are used in a wide variety of applications and must meet a broad spectrum of requirements. When it comes to axis motors in machine tools, for example, torque ripple and the inertia ratio between the motor and the load are crucial factors, along with the maximum torque. These criteria have a direct effect on the quality of the workpiece to be manufactured. HEIDENHAIN axis motors for machine tools offer a balanced inertia ratio and very low torque ripple for exceptional machining results and dynamic motion control.
Withstanding Disturbances
A system’s rigidity is a crucial factor in its resilience to vibrations or milling forces—the greater the rigidity, the better. Rigidity, in turn, is heavily influenced by the inertia ratio between the motor and the moving mass of the feed axis (load). This means that larger motors provide greater system rigidity against milling forces or vibrations. Figure 1 shows, as a function of the inertia ratio between the motor and the load, how high a sudden load reversal must be in order to temporarily cause a given position error in a drive.
By way of illustration, a lightweight trailer attached to a large, high-torque vehicle will introduce fewer disturbances into the entire system when exposed to wind gusts or road damage than will a heavy trailer pulled by a lightweight vehicle of the same torque. This is true even though the lighter trailer is obviously much more susceptible to these influences than the heavier one. For a machine tool, this means that the largest possible motor should be moving the lightest possible table in order to minimise the effect of disturbances on the entire system (such as milling forces or vibrations arising at the table).
Unfortunately, if there is a significant difference between the inertias of the motor and the load, it is also necessary to lower the loop gains. Lowering the loop gains leads to lower rigidity, meaning that the entire system reacts more strongly to load disturbances, e.g., from milling forces or vibrations.
For a machine tool, a balanced inertia ratio between the motor and the load should therefore be selected. A balanced ratio provides the amount of rigidity needed to make the entire system insusceptible to external influences exerted on the load, meaning that these influences have no effect on the machining result, and, at the same time, making it possible to work with high loop gains. In other words, the trailer and the vehicle pulling it should be correctly matched to each other.

Productive processes reduce unit costs and increase productivity in production facilities in the long term
In order to make this a reality, you need qualified employees who know how to fully utilise the potential of modern cutting tools as efficiently as possible in their work. Knowledge of tools and their applications is key to successfully achieving increases in productivity whilst reducing costs. We will help you to overcome these challenges with qualified technical training for your employees.
Highly-qualified staff will help to lower your costs
If you want to use high-calibre tools efficiently and would like to guarantee reliable processes, you have to have excellent specialist knowledge at your disposal. Only with sound knowledge of machining, processes and strategies will your employees develop long-term expertise, which will give your company a competitive advantage.
Small application with a big impact
On average, tool costs in a modern production environment account for around four to six percent of the total production costs. However, tools have an effect on the majority of production costs and therefore offer the greatest potential for optimisation.
