H5G and ESG Mini vices join WNT workholding range
1 min read
Two recent additions to the WNT workholding range are the H5G and the ESG Mini series of vices. The two systems sit at opposite ends of the scale with the H5G system offering clamping forces of up to 40 kN and, depending on the configuration, a gripping width of up to 499 mm. The ESG Mini is designed for smaller components and has a maximum gripping force of 12 kN and is suitable for multiple clamping set-ups using zero-point pallets.
A key feature of the H5G series is its pre-set clamping force which eliminates the possibility of over or under tightening the component. This makes it suitable for a wide range of components including those with thin walls. To lock and unlock the vice the mechanism only needs to be moved through an arc of 160º, so clamping can be completed in under a second.
The H5G series vice's low height of 125 mm mean that it can be accommodated by smaller machine tools. The clamping mechanism is fully sealed to protect against swarf and other contaminants and prolong the life of the vice. The location of the clamping spindle ensures minimal deflection of the clamping jaws, even at maximum gripping force.
The ESG Mini series offers a 40 mm jaw width as standard with a 100 mm width option. These jaws also provide a variety of helpful features that can help with machine/component set-up. For example, jaws are available with precision ruled marks and stops on them, or with indentations to allow quick positioning of components and also facilitate the removal and repositioning of components for inspection part-way through machining. As with the larger H5G vices the operating mechanism of the ESG Mini series is completely enclosed.
The fixed jaw of the ESG Mini series vices are manufactured from the same block of material as the vice base for strength and deflection resistance. The vice jaw system is fully modular allowing great variations in clamping options and the clamping mechanism can be specified as a manual or hydraulic system.
Both systems feature tenon or zero point location points making them suitable for most machine tools or set-up applications. The ESG Mini series is particularly suitable for multiple vice applications on base plates or tombstone-type fixture blocks. As with all other products from WNT the entire range of vices and accessories are featured in the extensive WNT catalogue and are all available ex-stock for next day delivery.
