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

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 loading/unloading, workpiece palletizing/depalletizing, welding, grinding, etc. 4) Milling machine fixtures: All mounted on the milling machine table, moving with the table 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 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, there is a wide variety of types and styles of bearing housing fixtures, accounting for a large proportion in both quantity and style. This type of bearing housing fixture can accurately determine the relative position between the workpiece to be machined and the cutting tool, meaning it can clamp the workpiece requiring machining, 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.

An 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 onto 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 waterproofing material into the interior of the base shell. 5) Manufacture the faceplate and install it together with the base shell part. Electromagnetic chucks use DC power supply and feature stability, strong holding force, and low residual magnetism. Electromagnetic chucks can be classified into standard-holding chucks and heavy-duty chucks based on different classifications. The holding force of standard-holding chucks is 10-12 kg/cm², while heavy-duty electromagnetic chucks are not less than 14 kg/cm². Based on application, they can be classified into electromagnetic chucks for grinders, electromagnetic chucks for milling and planing machines, electromagnetic chucks for tool grinders, etc.

1) Base components: Such as square, rectangular, and circular base plates, used as fixture tooling tables. The 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) Support components: Including U type angle blocks, L type angle blocks, support angle irons, angular connecting blocks, angle gauges, frame support bases, etc.; used for height positioning or platform expansion, and for positioning or clamping other accessories. These are elements such as shims, spacer plates, support plates, support blocks, and extension plates that are positioned 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 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; they are 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 the positional difference and gap 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 corner sleeves, 45 degree clamping corner sleeves, parallel clamping corner sleeves, vertical clamping corner sleeves, standard support legs, swivel caster support legs with brakes, fixed support legs, frame-structure support bases, hydraulic lift support bases, support rails; Purpose: Elements acting to connect 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 carts; Purpose: Auxiliary components supporting the assembly of tooling elements. 9) Assembly tools: Including hex keys, oil stones, magnetic pliers, and other assembly tools.
