German Koenig workpiece fixtures Koenig model Koenig price

Koenig workpiece fixtures refer to devices used in the manufacturing process to secure the workpiece in the correct position for machining or inspection, also known as jigs. Broadly speaking, any device used to quickly, conveniently, and safely install a workpiece during any step of the process can be called a fixture. Fixtures typically consist of locating elements (to determine the correct position of the workpiece within the fixture), clamping devices, tool-setting guide elements (to determine the relative position of the tool to the workpiece or guide the tool direction), indexing devices (enabling the workpiece to undergo machining at several stations in a single setup, including rotary indexing devices and linear indexing devices), connecting elements, and fixture bodies (fixture bases). Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures, among which machine tool fixtures are the most common and are often simply referred to as fixtures. When machining a workpiece on a machine tool, to ensure that the surface of the workpiece meets the technical requirements specified in the drawing, such as dimensions, geometric shape, and mutual positional accuracy with other surfaces, the workpiece must be properly located and securely clamped before machining.

Koenig workpiece fixture types

1) Standard rectangular electromagnetic chuck Application: Rectangular table surface grinders. 2) High-power electromagnetic chuck Application: Milling machines, planers, machining centers. 3) Fine-pole electromagnetic chuck Application: Rectangular table surface grinders, milling machines. 4) Multi-function high-power electromagnetic chuck Application: Rectangular table surface grinders. 5) Rotary electromagnetic chuck Application: Various surface grinders. 6) Electromagnetic chuck for tool grinding Application: Tool grinding machines. 7) Circular electromagnetic chuck (concentric type) Application: Circular table surface grinders. 8) Circular electromagnetic chuck (radial pole type) Application: Circular table surface grinders. 9) Circular electromagnetic chuck (plum blossom pole type) Application: Circular table surface grinders. An electromagnetic chuck is an electromagnetic fixture that secures the workpiece using the suction force generated by the chuck body when the electromagnetic coil is energized. The electromagnetic chuck consists of an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck.

Koenig workpiece fixture features

Workpieces for small-batch, high-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, 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 high-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 processing technologies such as CNC machine tools, machining centers, group technology, and Flexible Manufacturing Systems (FMS), machine tool fixtures have the following characteristics: 1) They can quickly and conveniently equip new products for production, shortening the production preparation cycle and reducing production costs; 2) They can clamp a group of workpieces with similar characteristics; 3) They can serve as high-precision machine tool fixtures suitable for precision machining; 4) They can serve as new types of machine tool fixtures suitable for various modern manufacturing technologies; 5) They adopt efficient clamping devices powered by hydraulic stations and other power sources to further reduce labor intensity and improve labor productivity; 6) They improve the standardization level of machine tool fixtures. This is mainly reflected in four aspects: standardization, precision, efficiency, and flexibility.

Koenig workpiece fixture selection and 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 of an electromagnetic chuck, the lifting capacity and its working class are the most critical. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of objects 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 also include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides. During installation, T-shaped screws can be screwed in for lifting, and T-shaped blocks and screws are used to fix them on the workbench. Connect the DC power supply and ground wire from the machine tool, then precisely grind the upper surface of the chuck once to ensure the parallelism between the upper surface and the bottom surface. When adsorbing workpieces, 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.
