Perfect curl for glasses

The new CNC 3D glasses frame bending machine S-514 produces glasses frames from a variety of metal profile wires, including stainless steel or titanium in different material thicknesses.

Whether oval, angular or round, or a plain gray or vibrant pink design; There is almost no limit to creativity, which is a decisive factor for purchasing glasses frames. The appearance is determined not only by shape and color, but also by the material. Eyeglass frames made of various metals such as stainless steel, new silver, phosphor bronze or titanium have been in fashion for several years. Schüssler Technik of Pforzheiml, under the state of Baden-Wurttemberg, is a specialized organization. This medium-sized company has been producing quality machines for the manufacture of spectacle skeletons for more than 50 years in the industry. The company’s products are also available for bending spectacle frames from metal wire profile, which is then the frame to fit on the spectacle lenses. Thanks to its machines,

Working principle of S-514 The
new CNC 3D glasses frame bending machine S-514 produces glasses frames from a variety of metal profile wires, including stainless steel or titanium in different material thicknesses. Hourly product output of the glasses frames reach 350 thousand. All known alloys up to 2.5 mm wide and up to 2.5 mm high can be used for spectacle frames. Baumüller’s precision and ideally adapted drive and automation components are relied upon as a highlight in highly accurate spectacle frames.
The programming of the machines takes place via data (a few form data from DFX or Schüssler Technik) via USB or network, or also by copying a molder. User; It has the opportunity to adjust parameters such as bending, correction values and steel wire thickness directly on the touch screen. Along with the shaped bend, the spectacle frames also achieve the desired radius of curvature, namely bottom curvature (front curvature). The way the machine works allows the wire to be adjusted so that the nut even in intense bends (eg sports glasses) is perpendicular to the middle axis. Thus, the lens can then be securely attached to the frame. Production without waste
One of the great advantages of S-514 is that segment corrections can be made. This; It means that the spectacle frame form can be divided into several segments until both the 2D form and the bent spectacle frame meet the quality requirements and then corrected. In particular, this is an extremely helpful feature in the critical range of eye types and wire profiles. Another added value of the machine is that it operates completely without waste. Thus, quality profile wires such as gold or titanium are also produced directly after each bending process without the next spectacle frame waste piece.
Thanks to the space-saving structure of the machine and the compact components of Baumüller, the electronics and all seven drives are located in a narrow space in the switchboard: four bending axes provide three-dimensional bending and three control axles to separate the wires. Axle drives provide high quality in bending and require no maintenance.

Complete drive system from one source
Most of the glasses produced worldwide are manufactured in Asia today. Demand in the market; long-lasting, space-saving and easy-to-use machines. Schüssler Technik shook hands with Baumüller as a competent and long-term partner in the development phase of the new 3D glasses frame bending machine. What was requested from the new S-514 was that it modernized the machine and made it compatible with Industry 4.0. Then the entire drive and automation system of the machine was produced in an ideally adapted manner by strategic partner Baumüller. All important components, from the drive control to the machine control and visualization, were available within the Baumüller Group. Sheet metal enclosure including switch cabinet, It was supplied by Baumüller Dravinja, the sister company of Baumüller, which specializes in machine enclosures and switch cabinet production. Baumüller also undertook all the engineering work of the machine.

Carstens: “We get fast and better application”
Schüssler Technik Business Development and Quality Management Department Manager Matthias Carstens, who stated that Baumüller supports them in all components and in the entire control system, said: the benefit is obvious. In this way, we have very little trouble, we get fast and better implementation, ”he said.
Besides space-saving, compact components, a prominent feature for Baumüller is its technical knowledge in the field of development and already available programming tools. With the perfect harmony of the regulator and the motor, the S-514 can produce glasses frames with a high accuracy of up to one percent of a millimeter. As a single unit, Baumüller’s b maXX 5500 servo inverter and six b maXX 3300 servo inverters control a total of seven drives of the machine.

Modern visualization and worldwide service

The modern visualization of the new S-514 allows the user to comfortably enter all the necessary parameters on the 12 “touch screen and control the machine. The use of symbols instead of language offers worldwide use without the need for translation. Tough as a machine control The new generation of the powerful performance b maXX PCC-04 series is a scalable and versatile platform for control tasks. Rupprecht: “There is a high demand”


The new 3D glasses frame bending machine S-514 also prepares our customers for Industry 4.0. The machine offers a digital user interface and optionally remote maintenance service for worldwide use. ”
As a manufacturer of machines to provide a fast and economical service, remote maintenance is extremely important for Schüssler Technik. The new machine optionally offers a remote control option for remote maintenance purposes thanks to the integrated router. Ubiquity, a safe remote maintenance solution by Baumüller, is one of the first software products in the field of industrial remote maintenance, certified in accordance with IEC 62443-3-3 and thus complies with the requirements of the core protection catalog within the Federal Office of Information Technology Security (BSI). Ubiquity; It provides safe access to machines worldwide to support during the installation, commissioning and maintenance phase, and to provide a safe remote diagnosis for faults or faults. Baumüller, offers the maintenance and preventive maintenance measures in the relevant place through the global service network. Thus, eyewear manufacturers worldwide can rely on the precise production of spectacle frames from the Schüssler Technik roof.

Summary: The
compact, digital and precise 3D glasses frame bending machine S-514 from Schüssler Technik and Baumüller together offers many new options such as modern visualization and secure remote control. The advantage of cooperating with a strategic partner and complete supplier such as Baumüller; It lies in the full range of expertise in both automation components and systems engineering.

How does the 3D glasses frame bending machine work?
Four bending axes produce the 3D glasses frame that runs parallel to the intermediate line:
– Coil sending,
– Wire bending,
– Bending the shape (front curvature),
– Counter-rotating for the upright nut to which the glass will be cut later.
The control axles, on the other hand, allow the cutting and putting forward of the wire :
– Positioning the knife,
– Cutting the wire ,
– Feeding the wire through the coil.
