Madhukar engg. Components offers precision vices for cnc machine. These vices are useful on cnc machining centres as well as on conventional milling machines and on surface grinders. Basically, the vice has modular construction of three parts, viz, base, moving jaw unit and fixed jaw. Any number of bases and jaw units can be combined to hold workpieces of different configurations and any size. Three units are usable to construct a chuck for a vertical lathe for example. All the members are manufactured from tool- steel, appropriately hardened and heat treated. The wedging action featured in the moving jaw provides heavy grip, prevents lifting of job and enables quick releasing. It ensures locking and fast setup as jaws are mounted on serrations ground on the surface of the base. These vices can be offered with swivel base or sine base premounted. Pallets mounted with a number of these vices can be provided in different sizes.
