The manufacturer of large-size molds relies on Schweiger Formenbau (Schweiger Tooling Manufacturing Company). In Germany, it relies on automation equipment to produce high-precision injection molds at competitive cost. In order to achieve the high process safety required, this home Large mold makers don't make any compromises. In terms of tools, they rely on the tool holders, heat shrinkers, dynamic balancing machines and tool setting techniques provided by system supplier Hanmer.
Schweiger GmbH & Co. KG, a family business from Uffing am Staffelsee, Bavaria, focuses on the most demanding industries: the automotive industry. For the general manager of Anton Schweiger and his 75 employees, this means every injection mould they produce. They must meet the highest standards of precision and quality. In addition, they also face tremendous market competition pressure from around the world.
However, in the face of global competition, this qualified mold maker and his team have adjusted and positioned accordingly. They rely on an automated process chain to ensure absolute process safety, so their injection molds can satisfy all Requirements. For example: The company built a new workshop in 2016 and invested in two 5-axis machining centers DMC 210U and 270U from Demagisen Precision, which can process very large parts at one time. Automatic exchange workbench system. These machines run 7 days a week, 7 days a week, and are operated by one person. The weekend is completely unmanned. This requires all the relevant parts and functions to have the highest process safety.
In view of this, Mr. Anton Schweiger is very concerned about the tool clamping technology, which is often overlooked as the interface between the spindle and the cutting tool. It is extremely responsible for the quality of the machining, spindle life and tool life.
Milling experts from Schweiger respect the advice and support of Hanmer from Igenhausen. For over forty years, Hammer, the family business has become the market leader in tool clamping technology in Europe. The technology of heat shrinking machine technology and dynamic balancing machine is recognized as the world leader.
Quality makes a difference
Andreas Orterer, production manager from Schweiger, believes that this strong partnership is based on the quality that Hanmer brings: » With Hanmer's products, we can ensure that we meet the highest standards of quality. » Schweiger is currently using Thousands of Hanmer's heat shrinkable shank, in addition, there are two heat shrinking machines and one dynamic balancing machine in the workshop.
Andreas Orterer added: » We have obtained all the tools that are very suitable for us from the same supplier, Hanmer. Moreover, the Hanmer heat shrink machine and dynamic balancing machine are developed by mechanics, easy to use and extremely efficient. » This review also applies to the UNO autofocus 20 | 70 tool setting tool, which is located between the heat shrink machine and the dynamic balancing machine in the Schweiger plant.
Since 2017, Hanmer acquired the Microset tool setting factory in Bielefeld, this product has become a product of Hanmer. Compared with the manual tool setting instrument, UNO autofocus semi-automatic tool setting instrument can automatically rotate the C axis. Focusing the cutting edge and measuring the size. Especially for tools with more cutting edges on the circumference, the semi-automatic tool setting instrument can save a lot of time. In short, this equipment can save up to 70% by setting the knife outside the machine. Preset time.
Andreas Haimer, General Manager of Hanmer Group added: » Through the acquisition of Microset tool setting technology, we have become a tool management system supplier for the machine tool industry. Microset tooling technology complements our original product technology series perfectly: High-precision tool holder and tool technology; heat shrink machine technology and dynamic balancing machine technology, so we can provide better support for customers. »
Automatically achieve the highest jitter accuracy
The partnership between Anton Schweiger and Hanmer, vice chairman of the German Tool and Mould Association, dates back 20 years, when he began using Hanmer's handle.
Twenty years ago, the mold maker purchased the first high-speed cutting machine. He gave up the collet-type shank due to the outstanding beating precision of the Hanmer heat-shrinking shank. Compared with other suppliers' products, Hanmer The excellent quality of the heat shrinkable shank finally won his trust. » The goal of Hanmer is consistent with ours. » » If the heat shrinkable shank is taken as an example, its runout accuracy is less than 3 microns by default. »
This is an important prerequisite for the mold maker from Uffing. Finally, they do not produce cheap injection molds, they provide very complex molds for the high-end truck industry, such as the production of two compartments for truck lighting housings. Injection Molding. These customers have extremely high requirements for the final product and do not allow for subtle flaws. The corresponding injection moulds have to meet similar requirements: As a rule, the surface must be as smooth as a mirror and the tolerance must be kept within 0.02 mm.
Schweiger's focus in production is the milling of large and complex molds, which can weigh up to nine tons. The cavity is very deep, usually between 300 and 400 mm, and sometimes as deep as 500 to 600 mm. These applications require Slender heat shrinkable shank, heat-shrinkable extension rod and cutting edge with extremely long handle. » Another advantage of Hanmer is the ability to offer a wide range of standard holders. If required, we can always order a variety of Non-standard design of the tool holder. » Production manager Orterer emphasizes. He once again pointed out that Hammer's standard and non-standard holders have extremely high runout accuracy, not only beneficial to the processing results, but also extend the spindle and cutting tool. life.
Long tool life for unmanned operation
In general, the longer life of the spindle means lower costs, but for automated production, tool life is even more important. » For unmanned operation, I need spindles, shanks and cutting tools that are absolutely reliable and long-lived. Anton Schweiger Explain.
When Schweiger processes many large injection molds, the non-stop processing time after one setup can be as long as 40 to 50 hours, sometimes as long as 100 hours. One tool break or spindle damage in unmanned operation will be fatal. In addition, to achieve the required surface quality, high rigidity and a firm connection are important. » The key to achieving this is Hanmer's tool holder, which ensures highly process-safe machining. The company owner added.
Not every requirement of this mold maker can be fully met by standard tool holders. Anton Schweiger is particularly pleased with the close cooperation with Hanmer experts and the flexibility of this company from Egenhausen. » For us, John It is very important to be able to listen to the user's needs. » The entrepreneur emphasizes that his Hanmer contact, Oliver Lechner, responsible for the South German sales manager, always responds quickly to the inquiry. Lechner said » »We supply Schweiger's many custom non-standard shanks, such as a non-standard tapered face milling shank, capable of milling cavities up to 360 mm deep. » Anton Schweiger adds: »These handles are perfect for use. In the size of the cutting tool and the corresponding cavity. This is why I can make the machine unmanned during roughing without concern. »
