German ganter workholding fixtures ganter model ganter price

ganter workholding fixtures are devices used in the manufacturing process to secure the workpiece in the correct position for machining or inspection, also known as jigs. In a broad sense, any device used to quickly, conveniently, and safely install a workpiece 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 in 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 (to allow 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 a workpiece on a machine tool, to ensure that the surface of the workpiece meets the technical requirements specified in the drawing, such as dimensions, geometric shape, and mutual positional accuracy with other surfaces, the workpiece must be properly located (positioning) and securely clamped (clamping) before machining.

ganter workholding fixture structure

1) Locating elements: These contact the locating reference of the workpiece to determine its correct position in the fixture, thereby ensuring the correct relative position between the workpiece and the tool and machine tool movements during machining. 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, nut 5 and open 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 machining requirements of the workpiece, 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, as they are key to ensuring the machining accuracy of the workpiece, with the aim of accurately positioning and securely clamping the workpiece.

ganter workholding fixture features

1) Chuck holding force: The electro-permanent chuck has extremely strong holding force, 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 accuracy: The holding force of the electro-permanent chuck 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 accuracy even if the workpiece extends beyond the table surface; 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 accuracy. 3) Performance: The electro-permanent chuck can be used continuously, even for more than 20 hours per day, without any failures or need for maintenance; ordinary permanent magnet chucks experience 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, and clamping and positioning are prone to obvious errors, resulting in a high scrap rate and very low efficiency; the electro-permanent chuck features automatic auxiliary positioning, allowing workpiece clamping or release to be completed in just 0.3 seconds with the simple press of a button, significantly improving production efficiency.

ganter workholding fixture classification

1) Base components: Such as square, rectangular, and circular base plates, used as fixture tooling tables. The five working faces of the table feature grid-marked holes. The flatness, parallelism, and perpendicularity tolerances of these five faces, 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 precision is required after combining tables, rails can be used to connect them. 2) Support components: Including U type angle plates, L type angle plates, support angle irons, angular connection blocks, angle gauges, frame support seats, 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, which are positioned on the platform to ensure the workpiece reaches a certain height requirement during machining, are mainly used for support at different heights. 3) Locating components: Including locating squares, locating straight edges, planar angle squares, V type locating components, and eccentric circle stops, used to accurately adjust the positioning location or height. These are elements used to precisely locate the workpiece to ensure it meets certain dimensional accuracy requirements during machining; they determine the relative position 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, 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 seats, hydraulic lift support seats, support rails; Purpose: Elements used for connection or support between components and other parts. 8) Other components: Including: retaining rings, grounding devices, spiral clamps, pipe clamps, lifting rings, cross-slot pressure pads, two-point clamping bridges, three-point clamping bridges, multi-purpose support templates, platform protective plates, tool trolleys; Purpose: Auxiliary components for assembling tooling elements. 9) Assembly tools: Including hex keys, oil stones, magnetic pliers, and other assembly tools.
