R mansukhlal & company manufactures precision grinding vices. Precision grinding vices are manufactured from ohns material duly heat-treated after stress relieving and stablishing process. It has been precisely ground and lapped to a perpendicular accuracy of 0.005 mm for parallelism, flatness and squareness with the vice in any position. Precision grinding vices can be used in sophisticated toolroom on surface grinders, tool and cutter grinders, milling machines, edms, etc. Precision grinding vices are manufactured in two types of camping, i.E., angular clamping and screw type clamping. Angular clamping vices are manufactured in four different range of holding capacity 75, 90, 100 and 125 mm and screw type clamping made in 100 mm holding capacity. Angular clamping vices are for high accuracy light machining, whereas screw type clamping vices are heavy-duty type.
