Production via precision machining

With flexible manufacturing concepts that are selected in line with demand, the MS Powertrain Technology Group gives you productivity, process stability and quality. We use latest-generation machining centers, and make effective use of single-spindle and multi-spindle machining. If necessary, we manufacture in a single clamping, using hydraulically operated, multiply adjustable tensioning devices - as well as process-specific combi-tools. Through process-oriented measurement we continuously maintain compliance with all tolerances.

Central core competence
Just as the uses of the various production plants are varied, the basic requirements we place on each machine are correspondingly and consistently high. After all, metal cutting is a central core competence of the MS Powertrain Technology Group. With the modern production facilities of a renowned machine tool manufacturer, we implement a wide range of machining technologies. Faster turnaround times, highly productive manufacturing and short chip-to-chip times are the result.

Vertical Milling
With two high-performance spindles we simultaneously process several workpieces completely, setting records in terms of productivity. The simple formula is: produce twice the number of workpieces within the same time! We relied here on highly productive machines from a renowned German manufacturer. The focus is on universality of use. Even with enormously heterogeneous workpieces, high flexibility and high-performance modules always ensure economically efficient production.

Horizontal Milling
Our horizontal machines guarantee high performance and precision, and are used in the MS Powertrain Technology Group for the production of large parts in particular. Flexible tool-holders enable, e.g., the production of large gearboxes. Reduced downtimes and maximum productivity are assured by innovative manufacturing concepts adjusted to the process, including integrated pallet changing systems.

Turning
Valuable lathes with high-quality machine elements are combined at our company with extensive accessories. The result: long-lasting precision for complex components. Our universal lathes are especially impressive for their power, torque, precision, and flexibility for long runs. Typical components created by turning at our company include rocker arm supports, the pins of which are located at various angles to one another. The components are not rotationally symmetrical, and their complex angular positions require special manufacturing expertise – a task that is perfect for the MS Powertrain Technology Group!

Hard turning is also a part of our processing spectrum. This involves a turning process in which already hardened workpieces are finished with the lathe. Using standard tools in this context, extremely precise internal contours and outer contours with high surface quality can be produced. Even grinding operations can be partially substituted by hard turning.

Surface grinding
Plane grinding is used in almost all areas of grinding for the generation of flat surfaces. We use it to perfect the functional areas of our products. So far there is no technically and economically viable alternative to ensuring perfect surfaces. At our company, surface grinding machines are used primarily for the manufacture of valve bridges, but they are universally resettable.

Cylindrical grinding
External cylindrical grinding also represents a common grinding method. Our high-torque drives and rigid machines guarantee consistent results here. With cylindrical grinding we give our products the desired surface accuracy and ensure the highest standards where dimensions and tolerances are concerned. During the grinding process we always keep up with the state of the art, and attach great importance to quality tools.

Tailormade
We process burrs produced during the manufacturing process with various deburring methods, all directly tailored to the product.

TEM
Where components with high deburring quality are required, our thermal deburring system comes into its own: TEM. This process is also often called explosion deburring. An oxygen-fuel gas mixture in an enclosed chamber ensures a completely burr-free component. Combustion of the burrs, which takes place at the component surface without material removal, takes only a few milliseconds, so that the workpieces are heated only slightly. All burs located on the workpiece are trimmed off. In addition, the bur roots are sealed – with the highest process safety. The TEM system of MS Powertrain Technology Group is characterized by a particularly large combustion chamber. Lateral and deep hole drilled rocker arm shafts with a length of 1.2 m are thus deburred reliably.

HD deburring
With high pressure deburring (HD), contact pressures up to 650 bar can occur. First, the components are pre-washed, then deburred, and then sent straight off to be washed and also vacuum dried. The MS Powertrain Technology Group uses a fully automated system here. HD-deburring reaches hard-to-access joins and drill-holes, for example at gate and valve housings.

Vibratory finishing
Vibratory finishing enables simple components to be deburred inexpensively and effectively. Here, workpieces or edges have corners or frayed edges removed. Depending on the component, the grinding bodies are directly adapted to the deburring process.

ECM
Electrochemical deburring (ECM) consists mainly of a resolution process at the anode. The positive pole of a power source is connected to the workpiece, and the negative pole to the tool. A small gap remains between the two parts, through which the electrolyte solution can flow. Via a chemical reaction, material is removed from the workpiece in a targeted manner. The advantages of ECM processing are obvious. Compared to manual, mechanical deburring of workpieces there are all kinds of benefits: in addition to the highest precision and cost savings through fewer rejects, automated processing with precisely coordinated ECM tools also increases quality. ECM enables the MS Powertrain Technology to work in parallel on up to twelve nests.

Using heat treatment, the properties of metallic materials can generally be modified within wide limits. The MS Powertrain Technology Group relies on different heat treatment processes in order to cater to as many customer requirements as possible.

Nitriding
Nitriding is a process for surface hardening on the basis of nitrogen. The result is a surface layer, which shows itself resistant to about 500°C. In nitriding we rely on external partners, with whom we have cooperated successfully for decades.

Hardening
Various hardening processes enable realization of various product requirements. The spectrum here includes induction hardening, carburizing and depth hardening. Components are hardened individually or in batches, depending on the application. During hardening we also work together with long-term, external partners wherever necessary.

Whether complex aluminum gear housings or steel components equipped with oil channels, there are many examples of high demands made on residual dirt. Here, the MS Powertrain Technology Group offers specially designed washing systems and processes. The highest levels of purity can be achieved via ultrasonic cleaning, in an effective, gentle, and environmentally-friendly manner. Contaminated components are placed inside a cleaning bath, which is made to vibrate via ultrasound. The energy released during the implosion is very high. Dirt particles are literally 'blown off' the material being cleaned.

We use a completely environmentally friendly cleaner for final cleaning. Of course, we always distinguish between the cleaning of aluminum and steel components. Flow-through systems with camera surveillance ensure maximum transparency. The purity filters are strictly checked and regularly maintained.

Unlike many other development service providers, we are certified according to DIN ISO/TS 16949 and DIN ISO 9001 as well as to DIN ISO 14001 and DIN ISO 50001. This demonstrates a high degree of structure, data security, documentation transparency and development transparency.

Since almost all our workstations are equipped with web meeting software and conference phones, an exchange in teams is also possible. Our ultra-modern meeting rooms enable integration of not only an audio but also a video conference system. This advanced equipment is the best way to guarantee the information flow.
