German industra workholding fixtures industra model industra price

industra workholding 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 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 machine tool's machining motion during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

industra Workholding 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 mounted on the spindle, while a minority are mounted on the saddle or bed. 2) CMM fixtures: Used on coordinate measuring machines, utilizing their modular support and reference devices to achieve flexible fixation of the measured workpiece. This device allows automatic programming to support the workpiece and can establish an unlimited number of workpiece configuration reference points. Advanced dedicated software can directly generate the workpiece clamping program within seconds using the workpiece's geometric data. 3) Industrial robot fixtures: All mounted on industrial robots for use in industrial automation equipment, representing one of the new technologies in modern industrial automation equipment. 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, grinding, etc. 4) Milling machine fixtures: All mounted on the milling machine table, moving with the table for feed motion. They mainly consist of positioning devices, clamping devices, fixture bodies, connecting elements, and tool-setting elements. During milling, the cutting force is large, and the cutting is intermittent with significant vibration; therefore, milling machine fixtures require high clamping force, and high stiffness and strength requirements are imposed on the fixtures. 5) Bearing housing fixtures: To ensure and improve the production quality of bearing housings, in addition to using 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. A bearing housing fixture is a production tool specifically used to ensure the product quality of bearing housings, making the bearing housing production process more convenient. Different bearing housing fixtures vary according to their structure, form, operating conditions, and design principles; therefore, the types and styles of bearing housing fixtures are diverse, accounting for a large proportion in both quantity and variety. This type of bearing housing fixture can accurately determine the relative position between the workpiece and the tool, meaning it can clamp the workpiece to be machined, thereby completing the motions required during the workpiece machining process. Since bearing housing fixtures play a very important role in the bearing housing production process, the drafting of bearing housing fixture design drawings is also very important.

industra Workholding Fixture Process

The electromagnetic chuck consists of a base shell, iron core, coil, faceplate, and junction box. Its manufacturing process is as follows: 1) Select suitable materials for welding or casting the base shell. 2) Install the iron core on the base shell according to the different types of chucks. 3) Wind the coil with the corresponding number of turns and technical parameters, dry it, and fit it onto the iron core. 4) Pour asphalt or other waterproof materials into the interior of the base shell. 5) Manufacture the faceplate and install it together with the base shell part. The electromagnetic chuck uses DC power supply and features stability, strong suction force, and low residual magnetism. Electromagnetic chucks can be classified into standard suction chucks and heavy-duty chucks. The suction force of standard suction chucks is 10-12 kg/cm², while heavy-duty electromagnetic chucks are not less than 14 kg/cm². According to application, they can be divided into electromagnetic chucks for grinders, electromagnetic chucks for milling machines and planers, electromagnetic chucks for knife grinders, etc.

industra Workholding 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 combining the table with other modules. The dimensions of the base table can be chosen arbitrarily, and special sizes can be custom-made. If high accuracy is required after combining tables, guide rails can be used to connect them. 2) Supporting components: Including U-type square blocks, L-type square blocks, 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. These are components such as shims, spacer plates, support plates, support blocks, and extension plates that position supporting elements on the platform to ensure the workpiece meets certain height requirements during machining, mainly serving as supports at different heights. 3) Positioning components: Including positioning squares, positioning straight edges, planar angle squares, V-type positioning elements, and eccentric circle stops, used to accurately adjust positioning location or height. These are elements that precisely position the workpiece to ensure it meets certain dimensional accuracy requirements during machining; used to determine the relative positions between elements, and between elements and the workpiece. 4) Adjustment components: Including: height adjusters, 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, hex head locking pins, magnetic pins; Purpose: Elements used for positioning and locking between components. 7) Assembly components: Including: 90-degree clamping angle sleeves, 45-degree clamping angle sleeves, parallel clamping angle sleeves, vertical clamping angle sleeves, standard support legs, swivel caster support legs with brakes, fixed support legs, frame-structure support bases, hydraulic lifting 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: Auxiliary components for the assembly of tooling elements. 9) Assembly tools: Including hex keys, oilstones, magnetic pliers, and other assembly tools.
