Utilizing machine tool capabilities is helpful for optimizing workholding solutions, whether a mechanical, pneumatic or hydraulic clamping design. Let's start with drawbar driven machine solutions, which are commonly used. A drawbar can be used to pull back towards the machine spindle, but in most machines, they can also do a little pushing out away from the spindle as well. It's important to note some machines have variable, or different capabilities, in one direction or the other. This means the force may be stronger pulling back on the drawbar than it is pushing out on the drawbar. It is important to determine this in advance so the proper work-holding design can be implemented.
