Another common type of work holding on a milling machine is clamps. If you 

have an odd shaped work piece or a large one that does not fit into a mill vise, 

you can clamp it directly to the mill table or fixture plate using clamps. Clamps 

are usually a bar type with an oval slot cut through the bar for a bolt and a 

tapped hole in the bar for a jackscrew. The jackscrew is set to be slightly longer 

than your work piece is tall. A small shim made of soft material .05” minimum 

thickness should be placed between the jackscrew and the machine table to 

prevent the screw from damaging the table when the clamp is tightened.

Set the clamp on top of the work piece and the jackscrew and shim on the 

table. Place a bolt through the slot in the clamp and screw it into a tee nut in 

the table’s tee slot and tighten the bolt to increase the clamping pressure. A 

series of clamps around your part should hold it in place during machining.
If you need to machine completely through the part, you will need to get the 

work piece off of the table. In this case, place blocks between your work piece 

and the table at the same locations where your clamps are. The blocks need to 

be directly under the clamps and all the blocks need to be the same height.

Another method of getting your work piece up off the table is to make a fixture 

plate. The fixture plate can be bolted to the machine table using tee nuts and 

bolts. Drill and tap holes where the clamps need to be. Clamp your part to the 

fixture plate as described above.

A third method of work holding is for round, cylindrical work pieces. A chuck 

with movable clamping jaws can be mounted to the machine table. The chuck 

works like the small chucks on a drill press or a drill motor. A chuck key is used 

to turn a screw in the side of the chuck, which moves all the clamping jaws 

simultaneously to clamp on a round work piece.
For information on other types of work holding or more information on the types 

discussed here, contact your local distributor of industrial supplies.
