Germany EROGLU workpiece fixture EROGLU model EROGLU price

EROGLU workholding fixture is a machine tool accessory manufactured based on the principle of electromagnetism. It generates magnetic force by energizing internal coils, firmly holding workpieces in contact with the surface of a magnetically permeable panel. Demagnetization and workpiece removal are achieved by de-energizing the coils to eliminate the magnetic force. Primary applications include workpiece fixation during the machining of ferrous workpieces on grinding machines, electromagnetic knife grinders, gantry milling machines, and gantry planers. Rectangular electromagnetic chucks have lifting threaded holes on both sides; T-head screws can be screwed in for lifting during installation. The chuck is secured to the worktable using T-head 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 parallelism between the upper and bottom surfaces. When holding workpieces, sufficient positioning holding force is 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.

EROGLU workpiece fixture classification

1) Lathe fixtures: Fixtures used on lathes to machine internal and external rotary surfaces and end faces of workpieces are called lathe fixtures. Most lathe fixtures are installed on the spindle, and a minority are installed on the saddle or bed. 2) CMM fixtures: Used on coordinate measuring machines, utilizing modular support and reference devices to achieve flexible fixation of measured workpieces. This device allows automatic programming to support workpieces and establish unlimited workpiece configuration reference points. Advanced dedicated software can directly generate workpiece clamping programs within seconds based on the geometric data of the workpiece. 3) Industrial robot fixtures: Installed on industrial robots for use in industrial automation equipment, representing one of the new technologies in modern industrial automation. They mainly appear in modern industrial production in coordination with robots, with common applications in automated unmanned factories for machine tool loading/unloading, workpiece palletizing/depalletizing, welding, and grinding. 4) Milling machine fixtures: Installed on milling machine worktables, moving with the worktable feed motion. They mainly consist of positioning devices, clamping devices, fixture bodies, connecting elements, and tool-setting elements. During milling, cutting forces are high and cutting is intermittent, causing significant vibration; therefore, milling machine fixtures require high clamping force, stiffness, and strength. 5) Bearing housing fixtures: To ensure and improve the production quality of bearing housings, in addition to machine tools and other mechanical equipment, a large amount of process equipment is used, including bearing housing fixtures, molds, cutting tools, and related auxiliary tools. Bearing housing fixtures are specialized production tools designed to ensure the product quality of bearing housings, making the production process more convenient. Different bearing housing fixtures vary in structure, form, operating conditions, and design principles, resulting in a wide variety of types and styles, accounting for a significant proportion in both quantity and variety. These fixtures can accurately determine the relative position between the workpiece and the tool, i.e., clamp the workpiece to be machined, thereby enabling the motions required during the machining process. Since bearing housing fixtures play a very important role in the production process, the drafting of their design drawings is also crucial.

EROGLU workpiece fixture classification

1) General-purpose fixtures: General-purpose fixtures are standardized fixtures that can be used to machine different workpieces within a certain range. Examples include three-jaw chucks and four-jaw independent chucks on lathes, and vises, indexing heads, and rotary tables on milling machines. These fixtures are generally produced by specialized factories and are often supplied 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) Dedicated fixtures: Dedicated fixtures are specifically designed for a particular operation on a specific workpiece. Their characteristics include 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. They are 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 adjusted to adapt to the machining of different parts. Fixtures used for group machining of similar parts are called group fixtures. Compared to group fixtures, general-purpose adjustable fixtures have less clearly defined machining objects and a wider scope of application. 4) Modular fixtures: Modular fixtures are assembled from a set of pre-manufactured standard components and parts according to the machining requirements of the part. Manufactured by specialized manufacturers, their characteristics include 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: Pallet fixtures are used on automated lines. These fixtures not only clamp the workpiece but also become integrated with the workpiece, moving along the automated line from one station to the next for different machining operations.

EROGLU workpiece fixture applications

1) Can stably ensure workpiece machining accuracy: When clamping workpieces with fixtures, the positional accuracy of the workpiece relative to the tool and machine tool is guaranteed by the fixture, unaffected by the worker's skill level, ensuring consistent machining accuracy for a batch of workpieces. 2) Can reduce auxiliary time and improve labor productivity: Using fixtures for workpiece clamping is convenient and fast; workpieces do not require scribing and alignment, significantly reducing auxiliary time. Clamping workpieces in fixtures increases workpiece rigidity, allowing for increased cutting parameters. Fixtures capable of clamping multiple workpieces or at multiple stations can be used, and high-efficiency clamping mechanisms can be adopted to further improve labor productivity. 3) Can expand the usage range of machine tools and achieve multi-functionality: By attaching different types of fixtures according to the forming motion of the machining machine tool, the original process range of the machine tool can be expanded. For example, installing boring jigs on the carriage of a lathe or the worktable of a radial drilling machine enables boring operations on box-type parts. 4) Ensure machining accuracy: Using fixtures for installation allows accurate determination of the mutual positions between the workpiece, machine tool, and tool. Workpiece positional accuracy is guaranteed by the fixture, unaffected by the worker's skill level, resulting in high and stable machining accuracy. 5) Improve productivity and reduce costs: Clamping workpieces with fixtures allows rapid positioning and clamping without alignment, significantly reducing auxiliary time. Clamping increases workpiece rigidity, allowing for increased cutting parameters. Multiple-workpiece and multi-station fixtures can be used with high-efficiency clamping mechanisms, all of which contribute to higher labor productivity. Additionally, using fixtures stabilizes product quality, reduces scrap rates, allows for the assignment of lower-skilled workers, and significantly lowers production costs. 6) Expand the process range of machine tools: Using dedicated fixtures can change the original purpose of the machine tool and expand its usage range, achieving multi-functionality. For example, installing boring jig fixtures on lathes or radial drilling machines enables boring of hole systems in box parts; dedicated fixtures can also convert lathes for broaching operations, fully leveraging the capabilities of general-purpose machine tools. 7) Reduce worker labor intensity: Clamping workpieces with fixtures is convenient and fast. When using pneumatic, hydraulic, or other clamping devices, worker labor intensity can be reduced.
