aba fixture Germany aba model aba price

aba 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 conductive 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-shaped blocks and screws, connect to the DC power supply and ground wire on 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 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.

aba fixture classification

Due to the different operating characteristics and structural forms of various machine tools, different requirements are correspondingly imposed on the structure of the fixtures used. According to the machine tool 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 clamping power source adopted, they can be divided into: manual fixtures, pneumatic fixtures, hydraulic fixtures, pneumatic-hydraulic fixtures, electric fixtures, magnetic fixtures, and vacuum fixtures. Specialized classifications include general-purpose fixtures, special-purpose fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and pallet fixtures. A pallet fixture is a fixture used on automated 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 automated line for processing different operations.

aba fixture classification

1) General-purpose fixtures: General-purpose fixtures refer to fixtures that have been standardized and can be used to process different workpieces within a certain range. For example, three-jaw chucks and four-jaw independent chucks on lathes, and vise jaws, indexing heads, and rotary tables on milling machines. Such fixtures are generally produced by specialized factories and are often provided to users as machine tool accessories. Their characteristics are wide adaptability and low production efficiency, making them mainly suitable for single-piece and small-batch production. 2) Special-purpose fixtures: Special-purpose fixtures refer to fixtures specifically designed for a specific operation of a particular workpiece. Their characteristics are 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 will be scrapped because it can no longer be used. It is only suitable for production with fixed products and large batches. 3) General-purpose adjustable fixtures and group fixtures: Their characteristic is that some components of the fixture can be replaced, and some devices can be adjusted to adapt to the processing of different parts. Fixtures used for group processing of similar parts are called group fixtures. Compared with group fixtures, general-purpose adjustable fixtures have less clearly defined processing objects and a wider scope of application. 4) Modular fixtures: Modular fixtures refer to fixtures assembled from a set of pre-manufactured standard elements and components according to the processing requirements of the part. Manufactured by professional manufacturers, their characteristics are flexibility, strong versatility, short manufacturing cycle, and reusability of components, making them particularly suitable for trial production of new products and single-piece small-batch production. 5) Pallet fixtures: A pallet fixture is a fixture used on automated 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 automated line for processing different operations.

aba fixture maintenance

1) Before use, check whether the limit dimensions are still in the correct position. 2) If the stop pin wear exceeds tolerance, it can be repaired by grinding; if the baffle, pin, or locating taper pin wear exceeds tolerance, it can be reassembled, shifting the worn areas to continue use. 3) Apply anti-rust oil after use. Regular long-term lubrication can maintain the life of synchronous fixtures; incorrect lubrication will lead to reduced clamping force, poor accuracy, wear, and seizing, so correct lubrication is essential. After machining, be sure to clean the body and slide ways of the synchronous fixture with an air gun or similar tool. During cleaning, remove the dust cover fixing screws and take off the dust cover, while opening the main jaws to the widest position to easily clean accumulated chips inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture every six months for thorough cleaning (at least every two months when machining cast iron or copper alloys). Check parts for damage or wear, and replace with new items immediately if severe. Lubricate thoroughly before assembly.
