German ortlieb workholding fixtures ortlieb model ortlieb price

ortlieb workholding fixture is a machine tool accessory produced based on the electromagnetic principle: energizing internal coils generates magnetic force, which passes through a magnetically permeable panel to firmly hold workpieces in contact with the panel surface; de-energizing the coils eliminates the magnetic force for demagnetization and workpiece removal. Main applications include workpiece fixation during machining of ferrous workpieces on grinding machines, electromagnetic knife grinders, gantry milling machines, and gantry planers. Rectangular electromagnetic chucks have lifting threaded holes on both sides; insert T-shaped screws for lifting, and secure 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 top surface of the chuck once to ensure parallelism between the top and bottom surfaces. When holding workpieces, sufficient positioning holding force is achieved by bridging two adjacent magnetic poles, allowing grinding operations. Magnetization and demagnetization of the workpiece can be controlled via the machine tool buttons.

ortlieb workholding fixture structure

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structural types of electromagnetic chucks include rectangular and circular shapes. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for fixing larger workpieces; transverse arrangement is suitable for fixing smaller workpieces. Circular chucks are suitable for fixing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed on the disk surface, magnetic suction force cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of the magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces of the same contact area; the point of application of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be arbitrarily changed. Therefore, disadvantages during machining include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

ortlieb workholding 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, general enterprises are still accustomed to extensively using traditional dedicated fixtures. In factories with medium production capacity, there are typically thousands to nearly ten thousand sets of dedicated fixtures. On the other hand, in enterprises with multi-variety production, approximately 50~80% of dedicated fixtures need to 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) Ability to quickly and conveniently equip new products for production, shortening the production preparation cycle and reducing production costs; 2) Ability to clamp 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) Adoption of efficient clamping devices powered by hydraulic stations, etc., to further reduce labor intensity and improve labor productivity; 6) Improvement of the standardization level of machine tool fixtures. This is mainly manifested in four aspects: standardization, precision, efficiency, and flexibility.

ortlieb workholding fixture usage

With the continuous development of China's industry, the use of electromagnetic chucks in industrial production is becoming increasingly widespread. The most important aspect of an electromagnetic chuck is its parameters; among the performance parameters, the lifting capacity and working class are the most critical. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight allowed to be lifted under specified working conditions, also known as the rated lifting capacity. Generally, the lifting capacity of a crane equipped with an electromagnetic chuck should include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting threaded holes on both sides; insert T-shaped screws for lifting, and secure 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 top surface of the chuck once to ensure parallelism between the top and bottom surfaces. When holding workpieces, sufficient positioning holding force is achieved by bridging two adjacent magnetic poles, allowing grinding operations. Magnetization and demagnetization of the workpiece can be controlled via the machine tool buttons. Before use, wipe the surface of the electromagnetic chuck clean to avoid scratches. Avoid severe impacts to prevent affecting precision. After use, clean thoroughly and apply anti-rust oil to prevent corrosion. When using an electromagnetic chuck independently, a ground wire must be connected to prevent electric shock from leakage.
