If the operator attaches a Unilock knob to the workpiece, he can easily move a part from one machine to another, doing rough cuts on a three-axis machine and fi nish work on the fi ve-axis. Zaya pointed out there’s a further advantage in being able to take a part attached to the workholding tool to the qualifi cation room where it can be mounted in the exact manner as it’s held on the cutting machines. In addition to base units and extensions with some very long lengths, BIG Kaiser has a modular stabilizer system for lateral support of large workpieces.
No Pallet, No Problem with Quick-Change Clamping When Fastems (West Chester, OH) needed to pick a workholding system for its six-axis robot-powered RoboFMS, it went with “zero-point” clamping from Schunk Group (Heu- chelheim, Germany), because of its quick-change ability and high repeatability, said California-based Robert Humphreys, Fastems international sales manager. “Our core business is factory automation and primar-
ily integration of metalcutting or composite-type machining centers,” Humphreys said. “And as a result of that busi- ness we’re obviously touching on other technologies, such as workholding, zero-point clamping and all those types of things that go hand and hand with creating a solution, so it’s something we’re very familiar with and use a lot.” Humphreys explained that the Schunk quick-change
system produces very high levels of clamping force. “One-point-fi ve, two, sometimes three tons of clamping
force in some cases,” he said. “So we’re creating clamping forces equivalent to the clamping forces securing a machine pallet within a typical HMC [horizontal machining center].” The Schunk quick-change system solves a number of problems, Humphreys said.
“It gives us a method of clamping a fi xture plate in a very easy and cost-effective way into, for example, a fi ve-axis trunnion machine with limited access,” he said. In a normal fl exible manufacturing system, machine pallets are required, which add to cost. But the RoboFMS
