German diamanttechnik workpiece fixtures diamanttechnik model diamanttechnik price

diamanttechnik workpiece fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They refer to fixtures specifically designed for a particular operation on a specific workpiece. Their characteristics include a 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 due to inability to reuse. It is only suitable for production with fixed products and large batch sizes. It contacts the positioning datum of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the correct relative position of the workpiece with respect to the cutting tool and the machining motion of the machine tool during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

diamanttechnik workpiece fixture applications

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

diamanttechnik workpiece fixture features

1) Chuck holding force: The electro-permanent magnetic chuck has extremely strong holding force, up to 16kg/cm², with uniform and adjustable magnetic field distribution. It is suitable for various heavy-duty machining, roughing, and finishing operations. Ordinary permanent magnetic chucks have weaker and uneven holding force, unable to meet the requirements of heavy-duty machining. 2) Machining accuracy: The holding force of the electro-permanent magnetic chuck does not require a continuous power supply to maintain. It generates no heat during continuous operation, avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface holding force ensures the highest machining accuracy even if the workpiece extends beyond the table surface. In contrast, ordinary electromagnetic chucks require a continuous current supply, generating heat after a period of operation. This not only causes thermal deformation of the workpiece but also reduces the magnetic force of the chuck, failing to guarantee machining accuracy. 3) Performance: The electro-permanent magnetic chuck can be used continuously. Even with continuous operation for more than 20 hours per day, no failures occur, and no maintenance is required. Ordinary permanent magnetic chucks show a decline in holding force after about half a year of use. Electromagnetic chucks can only operate for a few hours a day, are prone to malfunctions, and require frequent replacement and repair of internal components. 4) Operational efficiency: Using ordinary permanent magnetic chucks requires significant time for workpiece adjustment, accounting for 40%-50% of the entire machining process. Clamping and positioning are prone to obvious errors, resulting in a high scrap rate and very low efficiency. The electro-permanent magnetic chuck features automatic auxiliary positioning. Simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.

diamanttechnik workpiece fixture classification

1) Base components: Such as square, rectangular, and circular base plates, used as fixture tooling tables. All five working surfaces of the table feature grid-marked holes. The flatness, parallelism, and perpendicularity tolerances of these five surfaces, as well as the positional accuracy of the holes, are very high, ensuring sufficient accuracy for positioning on the table and for combination with other modules. Base table dimensions can be chosen arbitrarily, and special sizes can be custom-made. If high precision is required after combining tables, guide rails can be used to connect them. 2) Support components: Including U-type angle plates, L-type angle plates, support angle irons, angular connecting blocks, angle gauges, frame-style support bases, etc.; used for height positioning or platform expansion, and for positioning or clamping other accessories. Components such as shims, spacer plates, support plates, support blocks, and extension plates are positioned on the platform to ensure the workpiece meets certain height requirements during machining, primarily serving as supports at different heights. 3) Positioning components: Including positioning squares, positioning straight edges, planar angle squares, V-type positioning elements, eccentric circle stops; used for accurate adjustment of positioning location or height. These elements precisely position the workpiece to ensure it meets certain dimensional accuracy requirements during machining; they determine the relative positions between elements and between elements and the workpiece. 4) Adjustment components: Including height adjusters and adjustment shims; purpose: elements used to adjust positional differences and gaps between elements and the workpiece. 5) Clamping components: Including: 90° spiral clamps, horizontal spiral clamps, 45° spiral clamps, vertical quick-action clamps, horizontal push-type quick-action clamps; purpose: elements used to clamp the workpiece onto the platform or base components to prevent displacement during machining. 6) Locking components: Including: quick-locking pins, countersunk quick-locking pins, countersunk locking pins, handle quick-locking pins, locating pins, connection lock magnetic pins, hex socket locking pins, external hex locking pins, magnetic pins; purpose: elements used for positioning and locking between components. 7) Assembly components: Including: 90-degree clamping swivel sleeves, 45-degree clamping swivel sleeves, parallel clamping swivel sleeves, vertical clamping swivel sleeves, standard support legs, swivel castor support legs with brakes, fixed support legs, frame-structure support bases, hydraulic lift support bases, support rails; purpose: elements acting on the connection or support between components and other parts. 8) Other components: Including: retaining rings, grounding devices, spiral clamps, pipe clamps, lifting eyes, cross-slot pressure pads, two-point clamping bridges, three-point clamping bridges, multi-purpose support templates, platform guard plates, tool trolleys; purpose: accessory components for assembling tooling elements. 9) Assembly tools: Including hex keys, oil stones, magnetic pliers, and other assembly tools.
