German veith workholding fixtures veith model veith price

veith workholding fixture is a machine tool accessory product manufactured based on the electromagnetic principle. It generates magnetic force by energizing internal coils, tightly holding workpieces in contact with the surface of a magnetically permeable panel. Demagnetization and workpiece removal are achieved by de-energizing the coils to eliminate the magnetic force. Main applications include workpiece fixation during the machining of ferrous workpieces on grinding machines, electromagnetic knife grinders, gantry milling machines, and gantry planers. Lifting screw holes are located on both sides of the rectangular electromagnetic chuck; insert T-head screws for lifting during installation. Secure it to the workbench using T-blocks and screws, connect the DC power supply and ground wire from the machine tool, and then precision grind the upper surface of the chuck once to ensure parallelism between the upper surface and the bottom surface. When holding workpieces, sufficient positioning suction force is 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.

veith workholding fixture classification

1) Lathe fixtures: Fixtures used on lathes to machine internal and external rotational surfaces and end faces of workpieces are called lathe fixtures. Most lathe fixtures are mounted on the spindle, while a minority are installed on the saddle or bed. 2) Coordinate measuring machine (CMM) fixtures: Used on measuring machines, utilizing modular support and reference devices to achieve flexible fixation of measured workpieces. This device supports automatic programming to realize workpiece support and can establish unlimited workpiece configuration reference points. Advanced dedicated software can directly generate workpiece clamping programs within seconds based on the geometric data of the workpiece. 3) Industrial robot grippers: Installed on industrial robots for use in industrial automation equipment, representing one of the new technologies in modern industrial automation. They primarily appear in modern industrial production in coordination with robots, with common applications including automated loading and unloading of machine tools, workpiece palletizing and depalletizing, welding, and grinding in unmanned factories. 4) Milling machine fixtures: Installed on the milling machine worktable and move with the table during feed motion. They mainly consist of positioning devices, clamping devices, fixture bodies, connecting elements, and tool-setting elements. During milling, cutting forces are high, and the process involves intermittent cutting with significant vibration; therefore, milling fixtures require high clamping force, as well as high rigidity and strength. 5) Bearing housing fixtures: To ensure and improve the production quality of bearing housings, in addition to machine tools and other mechanical equipment, a large amount of process equipment is used, including bearing housing fixtures, molds, cutting tools, and related auxiliary tools. A bearing housing fixture is a production tool specifically designed to ensure the product quality of bearing housings, making the production process more convenient. Different bearing housing fixtures vary in structure, form, operating conditions, and design principles, resulting in a wide variety of types and styles, which account for a significant proportion in both quantity and diversity. This type of bearing housing fixture can accurately determine the relative position between the workpiece and the cutting tool, meaning it can clamp the workpiece to be machined, thereby enabling the necessary movements during the machining process. Since bearing housing fixtures play a crucial role in the bearing housing production process, the drafting of their design drawings is also very important.

veith 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 and replace product varieties to adapt to market demands and competition. However, most 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 rate of the fixtures is only about 10~20%. To meet the application of new processing 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 setup 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 applicable to various modern manufacturing technologies; 5) Adopt efficient clamping devices powered by hydraulic stations and other sources to further reduce labor intensity and improve labor productivity; 6) Improve the standardization level of machine tool fixtures. This is mainly reflected in four aspects: standardization, precision, efficiency, and flexibility.

veith workholding fixture maintenance

When using vacuum suction cups (without grippers), note that the manipulator's movement speed should not be too high; otherwise, shear forces will be generated on the suction cup, causing the product to easily drop during rapid twisting. In some cases, a gripper can be used to ensure safe transport of the product. Considering that the product may stick to the mold, an air gripper is usually installed to resolve this issue. When the product's surface area is too small or the product is too heavy for vacuum suction cups, the problem can also be solved by using grippers. If the product has strict appearance requirements, the clamped area must not be the outer surface. To address this, a sensor circuit can be installed. Once the gripper or suction cup has securely grasped the product, the sensor sends a signal to the manipulator, allowing it to proceed to the next operation. In cases where the manipulator's motion capability is limited and manual twisting or prying is required to demold the product or move it out of the molding area, a special cylinder capable of independent movement without relying on the manipulator can be added to improve the situation.
