6. Direct Mounting to the Table 1. Plain Milling Machine Vise The plain milling machine vise is used for holding work which has parallel sides. The vise is bolted directly to the table using the T-slots in the machine table. The plain Vise can be accompanied by a swivel base. 2. Swivel base Milling Machine Vise The swivel base is graduated in degrees and allows the vise to swivel in the horizontal plane. The swivel base gives the vise a greater degree of versatility, but should be avoided when doing heavy rough cutting operations because it reduces the rigidity of the setup. For milling operations involving compound angles a universal vise are commonly used. 3. Universal Angle Milling Vise The universal vise allows the operator to tilt the work piece 90 degrees in the vertic4l plane as well as swivel it 360 degrees in the horizontal plane. In high production situations an air or hydraulically actuated vise may be used. These types of vises are quick acting. They also maintain consistent clamping pressures from one part to the next. However, on most manual type milling machines the vise is opened or closed using a handle. When tightening a plain type milling machine vise it is not necessary to strike the handle of the vise. 4. V-Blocks V-Blocks hold and support round work for milling or drilling. V-Blocks come in many different sizes. On milling machines, V-Blocks are typically clamped directly to the table. A V-Block and a strap clamp being used to clamp a round part to the table. 5. Angle Plates An angle plate is an L shaped piece of Cast Iron or Steel that has tapped holes or slots to facilitate the clamping of the workpiece. Angle plates are used when parts need to have machining operations performed at a 90 degree angle to the axis of the table. 6. Direct Mounting to the Table Work that is too large or has an odd configuration is usually bolted directly to the table. This method of work holding takes the most ingenuity and expertise. There are a number of accessories that can he used help you set up the workpiece. A variety of commercially available clamp sets are available for directly mounting workpieces.
