                • As one of the most quality-sensitive components, the piston is partly responsible for cleaner combustion. It also ensures a long service life for the engine. Due to the optimization of the combustion chamber, the shape of the pistons is becoming increasingly demanding and must be adapted separately.
                  In engine construction, the machining of pistons is one of the most complex processes.

                  Here, WEISSER masters the entire process chain for complete machining. Very small tolerances are required, especially for the machining of the outer contour, but also the weighting in the area of flexibility is increasing. Nowadays, it must be possible to machine a wide variety of piston types on machines for the outer contour machining of pistons. Here we are not only talking about the design and size, but also about different materials such as aluminum or hardened steel.

                • Rotor Shafts

                • Rotor shafts, which are used in electric motors, are usually massive shafts with a small diameter. These rotor shafts do not have a high weight per se, but the small inner diameter of the shaft is the reason that a large laminated core is needed, which gives the complete rotor its high weight. For electric drive motors, the extra weight results in a reduction of the range of the vehicle.

                  In order to make the production of these components as efficient and economical as possible, WEISSER develops process-safe complete solutions with various loading systems such as robots or gantry loaders in order to be able to offer customers an integrated manufacturing system.

                • Differential Housing

                • The differential housing is and remains an indispensable component when it comes to drive concepts. The increasing quantities of this complex component bring with them a growing challenge. For the production of the differential housing, the classic high requirements of automotive engineering apply: high quantities, error-free processes, short cycle times. In addition, this connecting element, which is located in the middle of the differential gear, has an extremely complex shape. Therefore, the turning operation is demanding and takes place in several sub-processes. WEISSER offers unmatched expertise in this area due to countless customer projects. Individual machining processes are optimized economically and with the latest technologies, and thus offer an efficient manufacturing solution.

                • Planetary Gears

                • Usually, modern automatic transmissions consist of up to three individual planetary gears. In the simplest case, these consist of planetary gears, a sun gear, planet carriers and a ring gear. Planet carriers are used to hold the gears of a planetary gearbox. These planetary gears are being used more and more frequently due to their high efficiency. They are also characterized by their compact design as well as their high power density. WEISSER machining centers are predestined for the economical machining of these workpieces.

                • Gears

                • Due to the growing demands in gear manufacturing, the number of gears and gear components required is increasing. Therefore, components must be produced in ever greater quantities with high precision and efficiency. Here, at best, all processes are highly flexible. In order to be able to produce the various gear components such as disk carriers, shafts, gears or planetary gears at one location, WEISSER offers a wide range of machines and, thanks to automotive know-how acquired over many years, always the best manufacturing solution.

                • Brake Discs

                • When manufacturing brake discs, attention must be paid not only to a safety-relevant component, which must be manufactured with high process reliability and precision, but also to the high cost pressure. Therefore, the manufacturing of brake discs is not a simple process. WEISSER machines and brake disc production have the common feature of a high output quantity and a fast cycle time. As a specialist in brake disc machining, WEISSER has already realized a number of customized turnkey solutions in cooperation with various customers.

              • Technologies

                  • Rotational Turning

                  • With the rotation turning process developed and patented by WEISSER, precisely machined surfaces can be generated with twist-free finishing precision and thus replace the expensive grinding operations. The simultaneous rotation of workpiece and tool cutting edge reduces the machining time by up to 77 % compared with hard turning.

                  • Universal Machining

                  • WEISSER offers the option of turning and milling from the bar parallel to machining time. This for diameters up to 105 mm and a length of 1200 mm in a 6-sided complete machining. The 6-sided machining enables an excellent machining quality due to fewer reclamping processes. In addition, order throughput and machining times are significantly reduced, and the unit costs are noticeably lower.

                  • Out-of-round Turning

                  • 3 times capacity with WEISSER HOT system for shorter piece times and lower piece costs. The technology enables the highly productive machining of a wide range of workpieces, such as pistons for combustion engines, camshafts, polygonal profiles or the production of polygon shapes (shaft-hub connections) with process-oriented perfection.

                  • Internal/External Grinding

                  • Machining with the technology of external and internal cylindrical grinding in one machine is exemplary for perfect hard fine machining of rotationally symmetrical workpieces. In order to achieve optimum cycle times, this machining technology can be combined with hard turning or rotational turning processes.

                  • End Machining

                  • With the end machining technology, WEISSER offers a solution for the face machining of shafts. Typical processes include deburring, facing, chamfering, drilling, centering and spindle machining. In addition to contour machining at the ends, both single and double-sided machining of shafts is possible. The technology also offers advantages in terms of cycle time and availability.

                  • Gear Cutting (Hobbing)

                  • Integration of a hobbing module, being the only method to manufacture internal and external gearings with different helix angles and directions in a single machining center. This manufacturing process combines hobbing and slotting by continuous hobbing with maximum feed rate.

                  • 4-Axes-Machining

                  • Highly productive simultaneous machining in one machine with two powerful disk turrets (4-axes). Intelligent technology processes and the combination of different machining steps offer high savings potential. Working with two tools simultaneously shortens the machining times of the workpiece and thus reduces the cost per part.

                  • Whirling

                  • Compared to the milling of bearing cages, which are typically made of brass, shorter cycle times and tribological matched contours with greater precision can be achieved for cylindrical roller bearings.

                    Whirling or impact/turn-milled brass cages are perfect for heavy-duty bearings and therefore are particularly useful in planetary gearboxes, heavy-duty wind-power planetary gears, railway axles and construction equipment, such as cranes or excavators vehicles.

                    The WEISSER whirling method offers these unique user benefits:

                    • High efficiency due to the substitution of time-consuming and expensive manufacturing processes, such as milling, drilling and broaching or boring and punching
                    • Improved contact conditions between roller and cage bar with the new concave pocket-window geometry
                    • Ideal lubricant film formation in the rolling region with less wear
                    • Self-retaining function of the rolling elements due to concave ridge forms: Facilitated assembly due to snap-in assembly of the rollers without a separate device or caulking to prevent falling out

                    The method also allows efficient machining of stable full-mould cage forms so that they can be used instead of sheet-metal cages. This results in

                    • Greater solidity and durability in spite of a reduced overall mass, thereby reducing inertia forces in operation
                    • Increase of the static as well as dynamic load rating and service life due to the machining options for solid components
                • Solutions

                    • Weisser Turnkey Process
