    • Technology

        • Vertical turning

        • As the first machine tool company WEISSER presented the vertical turning with pick-up-machines (also called vertical pick-up turning). Thereby the focus was on loading and unloading of workpieces as well as on the integration of further processes as drilling and milling.

          With our VERTOR-lines we turn vertically with a fixed spindle. Loading can be made manually, automated or with a crane in case of big heavy workpieces.

        • Rotational turning

        • WEISSER is the first machine tool company which entered the market with the concept of a horizontal shaft pick-up machine. By the interaction of tailstock and working spindle the machining of workpieces between centres is possible.

        • 4-axis turning of shafts and chuck parts

        • With 4-axis machining, various machining steps can be combined in one process. Working with two tools simultaneously shortens the machining times of workpieces and thus reduces the unit costs.

        • Out of round turning

        • With the original WEISSER HOT system, the machining of non-circular workpieces becomes far more economical compared with milling or grinding, since any contours may be produced with just one turning process. This significantly improves not only the speed, but also the shape accuracy.

          Non-circular workpiece shapes are used among other things in general mechanical engineering, the automotive industry, in aircraft construction or electrical engineering. Special applications include pistons, connectors, sliding seats, coupling elements and shaft-hub connections (car gearboxes, control wheels, etc.).

          The out-of-round turning method developed by WEISSER

          • Replaces traditional forms of processing such as profile milling and grinding and/or profile grinding
          • Significantly reduces the processing time thanks to the special kinematics between the rotating workpiece and the oscillating tool cutting edge (freely programmable)
          • Generates high surface quality
          • Enables highly productive manufacture of regular polygons and disharmonious profile shapes with the highest precision and surface quality
          • Provides internal, external and face machining on the workpiece
          • Replaces profile connections (spline shaft connections) and parallel-key connections by polygonal workpiece shapes

        • Ends machining

        • The machining of shaft ends including milling, drilling and manufacturing of the total length of the shaft is possible with the series UNIVERTOR AE, UNIVERTOR AE-T as well as the vertical VERTOR EC from WEISSER.

        • Whirling

        • WEISSER whirling for highly productive turn-milling of cylindrical roller bearing cages and shaft-hub connections. Based on counter-spindle kinematics, special shapes, such as rectangular pocket windows, can be incorporated into workpieces with this procedure, which has been further developed by WEISSER.

          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.

          The shape of the cage bars is controllable by the whirling method, which allows perfect osculation of the rolling elements to the cage. The rolling elements do not need be mounted and fixed in a time-consuming way, but can be clipped into the cage by simple snap-in assembly.

          Whirling or impact/turn-milled brass or steel cages are perfect for heavy-duty bearings and therefore are particularly useful in:

          • Planetary gearboxes and heavy-duty wind-power planetary gears
          • Railway axles and construction equipment, such as cranes or excavators vehicles

          This method is not only useful for incorporating radial pockets in cage rings, but also for generating, for example, the following geometries:

          • Positive fitting shaft hub profiles (spur gearing)
          • Coupling profiles (positive fitting), such as claw and tooth clutches
          • Cycloid pockets and recesses for weight reduction

          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

        • Turning, drilling, milling, threading in one workspace

        • The combination of different manufacturing processes and work steps enables the production of complex workpieces in as little clamping as possible. The accuracy in terms of shape and position tolerances is thus significantly improved.

        • 5-axis turning/milling machining

        • The interaction of a full-size milling spindle with a tool changer and a turret enables the fusion of turning and milling operations on complex workpieces in a single setup using combined processes.

        • Rotational turning

        • With the rotation-turning process developed and patented by WEISSER, finely machined surfaces can be generated with twist-free finish precision, completely replacing time-consuming grinding operations. The simultaneous rotation of workpiece and tool cutting edge reduces the machining time by up to 77 % (user study) - a beneficial ratio effect.

        • Hard turning

        • Hard turning can be an adequate substitute for grinding of hardened workpieces. Hard turning can be performed as wet and dry machining.

        • Internal/external cylindrical grinding

        • Internal and external cylindrical grinding in one clamping achieves the highest precision and twist-free surface quality.

        • 3D friction coating

        • The process objective is based on a fast, cost-effective process for depositing metal coatings on metallic base materials under normal atmospheres.

            • ...always the right Tailor-made Solution

              Automated machine tools and/or turning centres that can be integrated into processes as well as system integrations can be used to reduce throughput and set-up times depending on the requirements' profile.

              We develop the optimum and efficient tailor-made solution as a process or system integration for each application in cooperation with our customers.

              Process integration:

              The machine finishing is achieved in a single set-up wherever possible with technology or process integration in a working area using the options of hard, out-of-round and rotational turning, drilling, threading, milling or grinding, amongst other things. This achieves high workpiece quality, contour accuracy and surface finishes. In addition, set-up, tooling, programming and idle times are drastically reduced.

              Variants of the WEISSER process integration:

              • Single or multi-spindle complete workpiece machining in a single set-up
              • Complete machining processing through follow-on operations in a multi-spindle working area and thus significantly reduced downtimes and maximum precision
              • Workpieces are picked up, transported and transferred to the automation fully automatically within the working area using the original WEISSER Pick-up System (WEISSER patent) or workpiece grippers.
              • Complete manufacturing with a turning station for the rear-face machining of workpieces in the second set-up
              • Process integration into manufacturing lines with automated workpiece transport
              • Highly productive and efficient process integration as a substitute for multi-stage production
              • Link to post-process monitoring stations, for example

              System integration:

              System integration through the intelligent and efficient link of manufacturing solutions, such as rotational turning/hard turning and gear grinding makes flexible and highly productive solutions from multiple machine systems possible. The advantage of extremely short cycle times in the individual processes remains completely unaffected. Workpiece handling, waiting times and the machine periphery are significantly improved through the system integration.

              Advantages of the process or system integration:

              • Reduction in the order throughput times using technologies perfectly coordinated with one another
              • Multi-stage production is conducted using one system
              • Complete automated machining reducing unit costs
              • Reduction in the in-plant logistics processes
              • High productivity per unit area by concentrating the complete supply chain on just a few square metres
              • Significant reduction in the investment costs for the automation
              • Link to post-process monitoring stations, for example

        • Applications

            • Pistons

            • The challenge:
              Complete machining at top quality for maximum yield and process reliability during out-of-round turning

              The solution:
              Precision lathe with WEISSER HOT system

              Specific production lines with machine models of the VERTOR and UNIVERTOR AM series are used for carrying out all process steps for the complete machining of pistons.

              Especially significant in piston machining is the out-of-round turning with the original HOT system (Hyperspeed Oval Turning) developed by WEISSER.

              The ideal basis for the take-up of the out-of-round machining system WEISSER HOT is the precision machine WEISSER VERTOR C. The production centre allows the highly productive manufacturing of regular polygons and disharmonious profile shapes with maximum precision and surface quality, and is used with high efficiency and excellent precision for the out-of-round turning of pistons, for example.

              Process:
              The process sequence range includes various operations, particularly on the piston neck, shaft, ring section, piston base and recess. This includes turning, drilling and milling work, in-process measuring and the out-of-round turning with the WEISSER HOT system.
