idealspaten-bredt fixtures refer to devices used in the mechanical manufacturing process to secure workpieces, ensuring they occupy the correct position for machining or inspection; they are also known as clamps. Broadly speaking, any device used to quickly, conveniently, and safely mount workpieces 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 and guiding elements (to determine the relative position between the tool and the workpiece or to guide the tool direction), indexing devices (allowing 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 workpieces on machine tools, to ensure that the workpiece surface meets the technical requirements specified in the drawings regarding dimensions, geometric shape, and mutual positional accuracy with other surfaces, the workpiece must be properly located (positioned) and securely clamped (clamped) before machining.

1) Locating elements: These contact the locating reference of the workpiece to determine its correct position within the fixture, thereby ensuring the correct relative position between the workpiece and the tool as well as the machine tool's machining motion during processing. 2) Clamping devices: Used to clamp the workpiece, keeping it in the established position within the fixture during cutting. As shown in Figure 6-1, this includes the nut 5 and the slotted washer. 3) Tool-setting and guiding elements or devices: These elements ensure the correct position between the workpiece and the tool. Elements used to determine the correct position of the tool before machining are called tool-setting elements, such as tool-setting blocks. Elements used to determine the tool position and guide the tool during machining are called guiding elements. 4) Connecting elements: Elements that connect the fixture to the machine tool, ensuring the mutual positional relationship between the machine tool and the fixture. 5) Fixture body: The base component used to connect or fix various elements and devices on the fixture into a single unit. It connects and aligns with relevant parts of the machine tool, giving the fixture a definite position relative to the machine tool. 6) Other elements and devices: Some fixtures require indexing mechanisms based on the workpiece machining requirements, and milling machine fixtures may also require locating keys, etc. Not all of these components are indispensable for every type of machine tool fixture, but any fixture must have locating elements and clamping devices. They are key to ensuring workpiece machining accuracy, with the aim of positioning the workpiece accurately and clamping it securely.

idealspaten-bredt fixture features

1) Chuck holding force: Electrically controlled powerful chucks offer superior holding force, reaching up to 16kg/cm², with uniform and adjustable magnetic distribution, suitable for various heavy-duty machining, roughing, and finishing operations; ordinary powerful chucks have weaker and uneven holding force, unable to meet the requirements of heavy-duty machining. 2) Machining precision: The holding force of electrically controlled powerful chucks does not require a continuous power supply to maintain, generating no heat during continuous operation, thus avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface holding force ensures the highest machining precision even if the workpiece overhangs the table; whereas ordinary electromagnetic chucks require a continuous current supply, generating heat after a period of operation, which not only causes thermal deformation of the workpiece but also reduces the chuck's magnetic force, failing to guarantee machining precision. 3) Performance: Electrically controlled powerful chucks can be used continuously; even with daily continuous operation for over 20 hours, no failures occur, and no maintenance is required; ordinary permanent magnet chucks show a decline in holding force after about half a year of use, while electromagnetic chucks can only operate for a few hours a day, are prone to malfunction, and require frequent replacement and repair of internal components. 4) Operational efficiency: Using ordinary powerful chucks requires significant time for workpiece adjustment, accounting for 40%-50% of the entire machining process. Moreover, clamping and positioning are prone to obvious errors, resulting in a high scrap rate and very low efficiency; electrically controlled powerful chucks feature automatic auxiliary positioning, completing workpiece clamping or release in just 0.3 seconds with the simple press of a button, significantly improving production efficiency.

idealspaten-bredt fixture maintenance

1) Before use, check whether the limit dimensions remain in the correct position. 2) If stop pins are excessively worn, they can be ground and repaired; if baffles, pins, or locating taper pins are excessively worn, 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 life of synchronous fixtures; incorrect lubrication leads to reduced clamping force, poor precision, wear, and seizing, so proper lubrication is essential. After machining, be sure to clean the synchronous fixture body and slide ways using an air gun or similar tools. During cleaning, remove the dust cover fixing screws and take off the dust cover, while extending the main jaws to their widest position to easily clean chips accumulated inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Completely disassemble and clean the synchronous fixture every six months (at least every two months when machining cast iron or copper products). Check parts for damage or wear, and replace with new parts immediately if severe. Lubricate thoroughly before assembly.
