German karg workpiece fixtures karg model karg price

karg workpiece fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They refer to fixtures specifically designed for a particular operation on a specific workpiece. Their characteristics include a 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 due to inability to reuse. It is only suitable for production with fixed products and large batch sizes. 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 machining motion of the machine tool during processing. It usually consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

karg workpiece fixture classification

Fixture types can be classified according to usage characteristics as follows: (1) Universal general-purpose fixtures. Such as machine vises, chucks, suction cups, indexing heads, and rotary tables, which have great versatility and can adapt well to changes in machining operations and workpieces. Their structures are standardized, and their dimensions and specifications are serialized, with most becoming standard accessories for machine tools. (2) Special-purpose fixtures. Designed and manufactured specifically for the clamping needs of certain product parts in a specific operation, serving a single purpose with strong specificity, generally designed by the product manufacturer. Common examples include lathe fixtures, milling fixtures, drill jigs (machine tool fixtures used to guide tools for drilling or reaming holes in workpieces), boring jigs (machine tool fixtures used to guide boring bars for boring holes in workpieces), and pallet fixtures (movable fixtures used on automated lines of modular machine tools). (3) Adjustable fixtures. Special-purpose fixtures whose elements can be replaced or adjusted. (4) Modular fixtures. Fixtures composed of standardized elements of different shapes, specifications, and uses, suitable for new product prototyping, single-piece and small-batch production with frequent product changes, and temporary tasks. In addition to vises, chucks, indexing heads, and rotary tables, there is a more common type called tool holders. Generally speaking, when the term "tool fixture" appears, it mostly refers to tool holders.

karg workpiece 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 meet market demands and competition. However, general enterprises are still accustomed to extensively using traditional special-purpose fixtures. In factories with medium production capacity, there are typically 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 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) Can rapidly and conveniently equip new products for production, shortening the production preparation cycle and reducing production costs; 2) Can clamp a group of workpieces with similar characteristics; 3) Can serve as high-precision machine tool fixtures suitable for precision machining; 4) Can serve as new types of machine tool fixtures suitable 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.

karg workpiece fixture maintenance

1) Before use, check whether the limit dimensions remain in the correct position. 2) If stop pins are worn beyond tolerance, they can be ground and repaired; if baffles, pins, or positioning tapered pins are worn beyond tolerance, they can be reassembled, shifting the worn areas to allow continued use. 3) Apply anti-rust oil after use. Regular long-term lubrication maintains the service 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 using 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 their widest position to easily clean chip accumulation inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture for a thorough cleaning every six months (at least every two months when machining cast iron or copper workpieces). Check parts for damage or wear, and replace with new items immediately if severe. Lubricate thoroughly before assembly.
