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 an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck. Electromagnetic chucks vary due to differences in design methods or materials used and are continuously developing and improving. Initially, electromagnetic chucks were used on grinding machines to replace clamping plates 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, which has significant limitations in its application. With industrial development, the demand for electromagnetic tools from enterprises has grown, and the requirements have become 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 fixtures is the same: 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 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; swing cylinders and lever cylinders provide clamping force on products; support cylinders prevent deformation during product machining. From simple fixation 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 increases, the precision requirements for fixtures inevitably rise. 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 and auxiliary time of 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 loading and automatic fixture changing devices have appeared on CNC machine tools, especially 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 and combination. The main variable process factors include operation characteristics, production batch size, and workpiece shape and dimensions. 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, small-to-medium batch production, expanding the 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 duty 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 electromagnetic chucks, 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 perform a precision grind on the upper surface of the chuck to ensure the parallelism between the upper surface and the bottom surface. When holding workpieces, sufficient positioning 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.
