staeubli fixtures Germany staeubli models staeubli prices

staeubli fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They refer to fixtures specifically designed for a particular operation of a specific workpiece. Their characteristics include compact structure, rapid, convenient, and labor-saving operation, ensuring high machining accuracy and production efficiency. However, the design and manufacturing cycle is long, and manufacturing costs are high. When the product changes, the fixture becomes obsolete and is scrapped because it can no longer be used. It is only suitable for production with fixed products and large batches. It contacts the positioning datum of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the correct relative position of the workpiece with respect to the cutting tool and the machine tool's machining motion during processing. It usually consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

staeubli fixture classification

Due to the different operating characteristics and structural forms of various machine tools, different requirements are correspondingly placed on the structure of the fixtures used. According to the machine tools used, fixtures can be divided into: lathe fixtures, milling machine fixtures, drilling machine fixtures, boring machine fixtures, grinding machine fixtures, gear machine tool fixtures, and other machine tool fixtures. According to the different clamping power sources adopted by the fixtures, they can be divided into: manual fixtures, pneumatic fixtures, hydraulic fixtures, pneumatic-hydraulic fixtures, electric fixtures, magnetic fixtures, vacuum fixtures, etc. Specialized classification includes general-purpose fixtures, special-purpose fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and pallet fixtures. A pallet fixture is a type of fixture used on automatic lines. This fixture not only serves to clamp the workpiece but also becomes integrated with the workpiece, moving from one station to the next along the automatic line for processing different operations.

staeubli fixture features

Workpiece varieties for small-batch, multi-variety production already account for approximately 85% of the total number of workpiece types. Modern production requires enterprises to frequently update their product varieties to adapt to market demands and competition. However, most enterprises are still accustomed to extensively using traditional special-purpose fixtures. Generally, factories with medium production capacity own thousands to nearly ten thousand sets of special-purpose fixtures. On the other hand, in enterprises with multi-variety production, approximately 50~80% of special-purpose fixtures must be updated every 3~4 years, while the actual wear of the fixtures is only about 10~20%. To meet the application of new machining technologies such as CNC machine tools, machining centers, group technology, and Flexible Manufacturing Systems (FMS), machine tool fixtures have the following characteristics: 1) Enable rapid and convenient equipment for new product production, shortening production preparation cycles and reducing production costs; 2) Capable of clamping a group of workpieces with similar characteristics; 3) Suitable for high-precision machine tool fixtures for precision machining; 4) Suitable for new types of machine tool fixtures for various modern manufacturing technologies; 5) Adopt efficient clamping devices powered by hydraulic stations, etc., to further reduce labor intensity and improve labor productivity; 6) Improve the standardization level of machine tool fixtures. This is mainly manifested in four aspects: standardization, precision, high efficiency, and flexibility.

staeubli fixture usage

With the continuous development of China's industry, electromagnetic chucks are increasingly widely used in industrial production. The most important aspect of an electromagnetic chuck is its parameters; among the performance parameters, the lifting capacity and its working class are the most critical. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of the load allowed to be lifted under specified operating conditions, also known as the rated lifting capacity. Generally, for cranes equipped with an electromagnetic chuck, the lifting capacity should also include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides. During installation, T-shaped screws can be screwed in for lifting. They are fixed to the workbench using T-shaped blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper surface of the chuck once to ensure the parallelism between the upper surface and the bottom surface. When holding workpieces, sufficient positioning holding force can be obtained by bridging two adjacent magnetic poles, allowing grinding operations to proceed. Magnetization and demagnetization of the workpiece can be controlled via the machine tool buttons. Before use, the surface of the electromagnetic chuck should be wiped clean to avoid scratches. Severe impacts are prohibited to prevent affecting accuracy. After use, it should be cleaned and coated with anti-rust oil to prevent corrosion. When using the electromagnetic chuck independently, a ground wire must be connected to prevent electric shock due to leakage.
