mineo outillages machines workholding fixture is a machine tool accessory product manufactured based on the electromagnetic principle. It generates magnetic force by energizing internal coils, firmly holding the workpiece in contact with the surface of the magnetically conductive panel. Demagnetization and workpiece removal are achieved by de-energizing the coil to eliminate the magnetic force. Main applications include workpiece fixation during 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-shaped screws for lifting during installation. Secure it to the workbench using T-shaped blocks and screws, connect the DC power supply and ground wire from the machine tool, and then perform a precision grind on the upper surface of the chuck to ensure parallelism between the upper and bottom surfaces. When holding a workpiece, sufficient positioning and 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.

Whether it is a simple hydraulic clamping fixture or a complex integrated production line, the design process for hydraulic fixtures remains the same, proceeding in the following order: formulation of the overall scheme, selection of hydraulic cylinder types and specifications, selection of control valves, design of mechanical components, selection of pump station accessories, and system connection. Hydraulic fixtures provide powerful clamping and positioning forces for various machining processes. Yun Dongli hydraulic cylinders are used for positioning and clamping in automated machining processes. Products such as self-centering vises and self-centering clamping elements provide accurate positioning; swing cylinders and lever cylinders provide clamping force on the workpiece; and support cylinders prevent deformation of the workpiece during machining. From simple fixturing to robot-assisted machining centers, hydraulic cylinders provide clamping and support forces to enhance production efficiency.

mineo outillages machines workholding fixture classification

1) General-purpose fixtures: General-purpose fixtures are standardized fixtures that can be used to machine different workpieces within a certain range. Examples include three-jaw chucks and four-jaw independent chucks on lathes, and machine vises, indexing heads, and rotary tables on milling machines. These fixtures are generally produced by specialized factories and are often supplied as machine tool accessories. They are characterized by wide adaptability and low production efficiency, making them mainly suitable for single-piece and small-batch production. 2) Special-purpose fixtures: Special-purpose fixtures are designed specifically for a particular operation on a specific workpiece. They are characterized by 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. They are only suitable for production with fixed products and large batches. 3) Universal adjustable fixtures and group fixtures: Their characteristic is that some components of the fixture can be replaced and some devices adjusted to accommodate the machining of different parts. Fixtures used for group machining of similar parts are called group fixtures. Compared with group fixtures, universal adjustable fixtures have less clearly defined machining objects and a wider scope of application. 4) Modular fixtures: Modular fixtures are assembled from a set of pre-manufactured standard components and parts according to the machining requirements of the part. Manufactured by specialized manufacturers, they are characterized by flexibility, high versatility, short manufacturing cycles, and reusable components, making them particularly suitable for new product prototyping and single-piece or small-batch production. 5) Pallet fixtures: Pallet fixtures are used in automatic lines. The fixture not only holds the workpiece but also moves as an integral unit with the workpiece from one station to the next along the automatic line for different machining operations.

1) Consistently ensures workpiece machining accuracy: When clamping a workpiece with a fixture, the positional accuracy of the workpiece relative to the tool and machine tool is guaranteed by the fixture, unaffected by the worker's skill level, resulting in consistent machining accuracy for a batch of workpieces. 2) Reduces auxiliary time and improves labor productivity: Using fixtures makes workpiece clamping convenient and fast, eliminating the need for layout and alignment, significantly reducing auxiliary time. Clamping the workpiece in a fixture increases its rigidity, allowing for higher cutting parameters. Fixtures capable of holding multiple workpieces or at multiple stations, combined with efficient clamping mechanisms, further improve labor productivity. 3) Expands the usage range of machine tools, achieving multi-functionality: By attaching different types of fixtures according to the forming motion of the machining machine tool, the original technological range of the machine tool can be expanded. For example, installing a boring jig on the carriage of a lathe or the table of a radial drilling machine enables boring operations on box-type parts. 4) Ensures machining accuracy: Installation using fixtures accurately determines the mutual position between the workpiece, machine tool, and cutter. Workpiece positional accuracy is guaranteed by the fixture, unaffected by the worker's skill level, resulting in high and stable machining accuracy. 5) Increases productivity and reduces costs: Clamping workpieces with fixtures allows rapid positioning and clamping without alignment, significantly reducing auxiliary time. Clamping increases workpiece rigidity, enabling higher cutting parameters. The use of multi-workpiece and multi-station fixtures, along with efficient clamping mechanisms, contributes to higher labor productivity. Additionally, the use of fixtures stabilizes product quality, reduces scrap rates, allows for the assignment of lower-skilled workers, and significantly lowers production costs. 6) Expands the technological range of machine tools: Using special-purpose fixtures can change the original purpose of the machine tool and expand its usage range, achieving multi-functionality. For example, installing a boring jig fixture on a lathe or radial drilling machine enables boring of hole systems in box parts; special-purpose fixtures can also convert a lathe for broaching operations, fully utilizing the capabilities of general-purpose machine tools. 7) Reduces workers' labor intensity: Clamping workpieces with fixtures is convenient and fast. When using pneumatic, hydraulic, or other clamping devices, workers' labor intensity is reduced.
