German optima workpiece clamping fixtures optima model optima price

optima workpiece clamping fixture is an electromagnetic chuck that secures the workpiece being machined by the suction force generated by the chuck body when the electromagnetic coil is energized. The electromagnetic chuck consists of several parts, including a core, coil, faceplate, and bracket. The electromagnet, composed of the coil and core, is the main part of the electromagnetic chuck. Electromagnetic chucks vary due to differences in design methods or materials used, and they are continuously developing and improving. Initially, electromagnetic chucks were used on grinding machines to replace clamps and bolts for securing workpieces to be ground. Such electromagnetic chucks are relatively simple and can only secure flat workpieces. This is the traditional electromagnetic chuck, and its application has significant limitations. With industrial development, the demand for electromagnetic tools from enterprises is increasing, and the requirements proposed are becoming higher, prompting a series of improvements to electromagnetic chucks to meet production needs.

optima workpiece clamping fixture applications

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

optima workpiece clamping fixture features

1) Standardization: Standardization and generalization of machine tool fixtures are two interrelated aspects. China already has national standards for fixture parts and components: GB/T2148~T2259－91, as well as standards for various general-purpose fixtures and modular fixtures. Standardization of machine tool fixtures facilitates commercial production of fixtures, helps shorten production preparation cycles, and reduces total production costs. 2) Precision: As the precision of mechanical products continues to improve, the precision requirements for fixtures inevitably increase accordingly. There are many structural types of precision fixtures, such as multi-tooth discs for precision indexing, with an indexing accuracy of ±0.1"; and high-precision three-jaw self-centering chucks for precision turning, with a centering accuracy of 5μm. 3) High efficiency: High-efficiency fixtures are mainly used to reduce the basic time and auxiliary time for workpiece machining, thereby improving labor productivity and reducing workers' labor intensity. Common high-efficiency fixtures include automated fixtures, high-speed fixtures, and fixtures with clamping force devices. For example, using an electric vise to clamp workpieces on a milling machine can improve efficiency by approximately 5 times; using a high-speed three-jaw self-centering chuck on a lathe ensures that the jaws can still firmly clamp the workpiece at a test speed of 9000r/min, thereby significantly increasing the cutting speed. In addition to configuring corresponding high-efficiency and automated fixtures in production lines and automatic lines, various fixtures for automatic workpiece clamping and devices for automatic fixture changing have appeared on CNC machine tools, especially on machining centers, fully leveraging the efficiency of CNC machine tools. 4) Flexibility: The flexibility of machine tool fixtures is similar to that of machine tools. It refers to the ability of machine tool fixtures to adapt to variable process factors through adjustment, combination, and other methods. The main variable process factors include operation characteristics, production batch size, and the shape and dimensions of the workpiece. New types of fixtures with flexibility characteristics mainly include modular fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and CNC fixtures. To meet the needs of modern mechanical industry for multi-variety and small-to-medium batch production, expanding the degree of flexibility of fixtures, changing the non-detachable structure of special-purpose fixtures to a detachable structure, and developing adjustable fixture structures will be the main direction of current fixture development.

optima workpiece clamping fixture selection and use

With the continuous development of China's industry, electromagnetic chucks are increasingly widely used in industrial production. The most important aspect of an electromagnetic chuck is its parameters; among the performance parameters, 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 the load allowed to be lifted under specified operating conditions, also known as the rated lifting capacity. Generally, for cranes equipped with an electromagnetic chuck, the lifting capacity should also include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting threaded holes on both sides. During installation, T-shaped screws can be screwed in for lifting. They are fixed to the worktable using T-shaped blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper surface of the chuck once to ensure the parallelism between the upper surface and the bottom surface. When holding 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.
